  1. That made a lot of sense. And when he said, if you don't get paid, still feed back, it is easier and simpler. I like that logic. Why waste money and complicate your system design. Let me guess, the pic below is not allowed in SA, as it will feed back? ESS without meter:
  2. And there I learn something! My upgrade path after my Phoenix (if it ever goes) is then all set for a Multigrid, have all the parts. Sell the BMV and to offset some of the new inverters cost. :-)
  3. I always say, when the insurance industry acts, then you get down to "facts. Like "global warming". Insurers have started to act, and their stats are for real. This part got my attention in the article below, I quote: One key player has not been swayed by all this wireless-friendly research: the insurance industry. In our reporting for this story, we found not a single insurance company that would sell a product-liability policy that covered mobile phone radiation. “Why would we want to do that?” one executive asked with a chuckle before pointing to more than two dozen lawsuits outstanding against wireless companies, demanding a total of $1.9bn in damages. https://www.theguardian.com/technology/2018/jul/14/mobile-phones-cancer-inconvenient-truths?utm_source=esp&utm_medium=Email&utm_campaign=GU+Today+main+NEW+H+categories&utm_term=281086&subid=22723954&CMP=EMCNEWEML6619I2 Makes me wonder of the effect of wifi in the house with small kids / babies. Older kids with phones glued to their person, 24 hours a day. (yes, they use them when you think they sleep, or it is right next to their beds.) :-)
  4. Don't. You are new, lots of thoughts and questions. Lots of answers and explanations. While from now, someone reads it all, identifies with what you asked, and learns from it. Time is then well spent. This is a information site, not a Google quick short answer site. :-)
  5. A thought on that. gennies are cheaper than a huge bank you seldom use. Like with ad hoc extended power failures. And, because the gennie is used to power stuff AND charge the batts, every ounce of fuel is optimally used.
  6. It was not the intention, I just wanted to share the Blue teams passion for the expensive equipment we have. No, we are not justifying the expense, it really works out the box. I mean, who in this world gives a 5 year warranty, free software and support? T105RE's are 6v batteries and they have 4000 cycles (8 years) at 20% DOD. So you can use them to 20% each and every day. If you push them to 50%, you have 1600 cycles. They are tried and tested solar batteries. No surprises with them if you follow the rules and keep them filled. On T105RE's you aim for 20% DOD on average. 10% is not enough to use them over their lifetime. 10% is good on UPS batteries. That decision is made when you buy the solar inverter. Till that point, you can be 12/24/48v, as UPS inverters are cheap. You will tweak the system part by part till you find the perfect medium, that is where Wife does not give you a lot of words and ultimatums about why the power is off when you are far far away. It is a journey, if she buys in, it is really cool. From what I gather, wife is in, so you are good to go. :-) I used to run a Intel server, 27" screen and router for up to 8 hours off 2 x 105ah batteries, repeatedly. That was pushing them yes, as they did get close to 50% DOD and are NOT designed for that, not like solar batteries are. A+ fridges and freezers are supposed to be good for 12-48 hours, T&C's apply. Then there is also a case to be made for what is in them. we buy very expensive fridges to keep a few rands worth of goods cool. If you fridge/freezer is full, that is another case. Therefor today I have 4 x T105RE's. They can take it with ease. My thinking is, and some on the forum disagrees, is that 12/24v has a benefit in that when, not if, when a battery goes, you have less of an expenses than when one battery goes on a 48v bank. That one problem battery drags the rest down, so you have a choice, buy 1 new one and drag it down, or replace all. Now a 48v bank has more storage yes, but you can have same storage on a 24v bank, if you need that. It all comes down what you want powered for how long and what max amps come out of the batteries. Computers, routers, lights A+ fridge and that, long backup times, 12/24v is fine. A house, 48v. Cheapest bank is a 12v system BUT you are limited in the max system size. My rule of thumb, as in continuous, not peaks: 12v - ideal 250w pushing at 1000w (Victron has 12v 5000va inverters - good for peaks, never continuous on 12v) 24v - ideal 800w pushing at 2000w 48v - above 3000w, you can go big. So it is knowing your continues load, making sure the bank is not stressed, that is it. O, 12v has more amps in the cables than say 48v. Bleh say I, go 35mm cables (if you want go 50mm) on the batts and to inverter and be done with it. For if a 48v system pulls 5000w or a 12v system pulls 1000w, if the connections or fuses are not correctly done, both systems will have an issue. :-) 12v just sparks better see, bigger bang for your buck ... literally. :-) Any case, the inverter is the key deciding factor, 12/24/48, as the MPPT, batteries and panels, can do all three voltages. So call is yours, 48v or not, keeping in mind the new batt tech in Pylontechm being 48v. Plonskter can guide you. I would budget for a VenusGX, cable per deivce, for the magic happens in there. And do not forget the BMV battery monitor. It is the key in switching the system. Happy batteries = happy wife. (... if you have to spend thousands on a new bank due to overuse) I am starting to think yes, skip the UPS, go Multiplus direct. Would keep controller apart, you have more room to maneuver ito the future or if something has to break. I view it as so: Panels + MPPT + batteries the entire fuel system. BMV the gauge of the "tank" Inverter the engine engine. But, if you want it all as one, nothing wrong with that at all. It has more of a Plug and forget, with slightly less room to move. Multiplus and VenusGX and BMV combination can auto-start a generator, if the gennie has the capability. Or BMV alarm goes off, DOD is say 30%, you can manually switch on the gennie.
  7. We don't buy from Sustainable. :-) No, we don't. Look at Current Automation prices. Attached a pricelist for you. There are two camps here. Axpert or Voltronic and copies of Axperts (everyone bar 2) and Victron (the 2) Plonkster and I. There are more Blue supporters, but they are very quiet or have left, as their systems work. :-) Both Plonk and I use 1.2kw inverters, mine a Phoenix, just inverter, as when I started, things where even more expensive than when he started. Victron's MPPT's and later inverter, are good. Pricey (depends how you see it), but very good. You don't have to sukkel ever, firmware is updated automatically, lots of options to adjust to fit any battery bank, backed by good support etc. vs Axpert, blerrie good price, but no support bar here, and from Australia, clever guys there, to upgrade the firmware. You want to tinker, tamper, do-your-own-thing, cheap, then go Axpert. You want to "plug and forget", more options later, the go Victron, and worth the spend if you don't like to tinker. Batteries, either Trojan T105RE's or the new Lithium banks / PolyonTech. Both are used by lots of people here on the site. PolyonTech you can add more batteries later on as you need. UPS charging may be an issue. They are expensive. Use them a lot! Trojan's needs TLC ito adding water, cannot add more batteries later. Less expensive. UPS can charge them. 4000 cycle on 20%, 1600 on 50% use. Use them a bit. Or 200ah Truck batteries. Cheapest option, for learning and not draining them below 10% on average, or 50% on very rare occasions. Like a real UPS application. Light use. Axpert and Victron MPPT's work on all the above, Trojan's are better than truck batteries and PolyonTech is the best, and the most pricey. Plug and Forget, go PolyonTech. Just need to ensure the UPS can handle the charging. Or go cheaper, seeing as batteries are going to be replaced in the future, and start with 200ah truck batteries. UPS'es are mostly modified sine wave, if you want the fridge now on UPS, you have to go sine wave, then UPS is not worth it, spend the money rather on a solar inverter. Keep the fridge for later? Focus on stuff that brings money in now. Inverter with MPPT built in, like Axperts, you decide day 1, 24 or 48v. And best you go 48v. Victron separate MPPT's are 24/48v auto adjustable, so you can later change over to 48 with 3kva inverter, or stay 24v. Me, I see no need to go 48v unless you want a big battery bank. I'm 24v. Have Victron MPPT's (2) and can go 48v if I want, if I replace the inverter ... No. But if inverter ever breaks, maybe then I'l go 48v. 6 years in no sign of issues at all. YES!. All inverters I have sold during the Eskom fiasco, I made sure they can run unplugged, stupid if they cannot. Just earth them. Gas can be more expensive then Eskom. :-) But I hear you. It is good for power issues! And better for ANY inverter not to power a stove. Good luck on that one. Eskom still has to run, or the country goes up in smoke. To make it all green, she has to start letting go of the hairdryer. Luxury see. :-) Then she must switch off everything that is not used, lifestyle change, as so many of use here had to "teach" the wifes and kids. Some of use did not make it. Rest their souls .. only joking. Some did end up in hospital, SWAMBO got upset. :-) So, to sum up: 1) Batteries, you have ideas above and a PM. Once you have given us the load, we can help you spec the bank size. 2) The final load, one day, dictates the inverter size. 3) And the above would all be catered for because you will by a MPPT (if you go separate) that can handle any future changes. 4) Panels can be added as needed. Plonksters suggestion on a small Multiplus is very good idea, with a bigger MPPT for more option later. Start with one, then if you need more power later, get a 2nd one. Maybe you stick with one, like we both have been doing for many years. AND ... Plonksters system is grid tied, if you want to go that far later. But lets not confuss the matter now. One issue at a time. Last though for now: I have separate circuits for all stuff that is solar. Fridge / Freezers are on / off solar, based on the season. Lights are on changeover switch between Eskom (cheaper) and solar (power failures) All computers TV's, DSTV are on separate circuit. For daytime solar, evenings Eskom, with option to go over to solar with power failures. This way I control the battery SOC and what is on and what is off, by hand. For summer and winter here is a huge difference, seeing as we have rain in winter. Geyser is on EV tubes, works best in cloudy weather. PV panels are pretty weak, compared to EV tubes, on a Cpt winter cloudy dayS. Geyser on solar draws 2000w, so on a small inverter, little else can be on, so you have to spend more for bigger inverter and panels ... EV tubes is best for water heating, I have been shown. And you can make it so, with training everyone, that they shower right, and seldom use Eskom, and save the planet, sorry water. Once you got solar sorted, read on the forum about saving water, for THAT is saving the planet, like Cpt did collectively, this last few months. If I could redo the house, I would have 2 pipe systems. One for toilets / bath / showers for pure rainwater feed, drinking water for municipal water. Why? Potable water is expensive to do oneself. You don't need potable water for showers / toilets. VICTRON-2018.pdf
  8. Welcome Fredhen. We'll sort you promptly. :-) Unless they changed it, those Mecer inverters are pretty loud ito the fan. Cyberpower UPS are really quiet. Fan only on when needed. Correct, solar is a tough ROI, sums have been done, doing it on credit, makes it even worse. Good idea to start with a UPS!!! Focus on the right battery bank for the loads, for that is one of the most expensive parts of going solar. O, and do get a BMV Battery Monitor and cable WITH the bank. After a while, once all is settled, you see where you are going, now get a separate MPPT (larger than you need, trust me) with solar panels matching the battery bank charging with the load. Why? With the MPPT and panels, you start charging the batteries so that you can use the UPS for longer hours, and not using Eskom to charge the batteries. UPS is a inverter. Now, the UPS inverter will fail, so buy a 2nd hand one for like R1000, for they are not designed to run day in and day out. Get some ROI out of it before it goes. At the time of the UPS popping, you have the battery bank properly specced, panels are in place and MPPT (with loads more capacity), now you buy a decent solar inverter. Cost nicely spread over time, as you learn, AND you solved your immediate worry of Eskom failures. Next thought. The moment you start talking things like oven / hairdryers / kettle in the same sentence as solar, you are looking at bigger inverter/s to handle the loads, for people will switch more on than the inverter can handle, and your computers go down. :-) Now take a oven, when is it mostly used? Evenings right? Hairdryers early mornings. Lights are evenings. Think of when the loads are mostly used for if not in the ideal solar times, then batteries are required ... and Eskom is cheaper than batteries. Plus, the big loads mentioned require bigger inverter/s. From 5kva to 10 kva - this roller coaster can blow your hair back if you don't reign it in. ;-) So my thinking with my system was take all loads that are below 1000w, put that on solar, rest stays on Eskom. These loads in my case are, guess what, home office. :-) So morning till evening all the office stuff is on solar, sometimes I add more loads, other times I remove loads. Sometimes in summer I leave stuff on solar 24/7. Winter in Cpt, tough on solar. For Eskom failures, I have Trojan T105RE batteries, which only powers the most important equipment, in case we need many hours of use. The loads costing you money are the ones that are on 24/7/365. Find them. My biggest saving, switched all loads off when everyone sleeps. How does the above sound to you?

    No man, not that one, the other one ... not sure who is in charge, then speak to the man who is in charge. :-) Till she fires him or whatnot. This one: Ian Nielson Professional career He worked across South Africa on various engineering projects. Key water supply projects that he worked on were a detailed basin study of the Luvuvhu River Basin (a tributary of the Limpopo River) and the Orange-Vaal Rivers Weir project (an envisaged alternative to the Lesotho Highlands Water Supply System). He also worked on a number of flood and storm water projects, most notable of which was the design of the canal system at Century City, Cape Town. It the latter part of his career he established himself as an expert in pipeline design and pipe network planning.

    Land Expropriation without Compensation - Truth and Fake News

    I have NO idea what you are talking about? The part I do get "simply too privileged to know that it has just happened", I don't pick up nuances or slights when people talk, sometimes I pick something up (humor a lot), but unless it is said, it is assumed on my part, therefor don't take it to heart, ignore. My wife on the other hand is very good at reading between the lines of what is not said. Sometimes I ask her, what did s[he] just say, when she explains in detail, a whole chapter that I missed! I am very privileged in that regard .. blissfully unaware. :-) FWIW. Not much makes us different from animals. Not even owning land (grond) in Afrikaans. Want DIE land is MY land. :-)

    Land Expropriation without Compensation - Truth and Fake News

    Yes, THAT makes sense ... especially when they grow up, for like water, the father cannot easily "contain" in order to "protect". NO laughter when she starts dating. So when we speak about "land" to farm on and "die land SA" in Afrikaans, versus "grond" to farm on in Afrikaans and "soil" in English, we are already confussed. :-) Then we have religion and emotions and toils and troubles to keep the land and the banks ... man we are making it complicated! Where are the days if I want land, I just take it. (cwl)

    Land Expropriation without Compensation - Truth and Fake News

    And on the matter of land, and how we discuss it, and what motivates our discussions, I think doing it in English complicates it even more. Let me demonstrate: Homographs are words of like spelling but with more than one meaning. A homograph that is also pronounced differently is a heteronym. 1) The bandage was *wound* around the *wound*. 2) The farm was used to *produce produce*. 3) The dump was so full that it had to *refuse* more *refuse*. 4) We must *polish* the *Polish* furniture. 5) He could *lead*if he would get the *lead* out. 6) The soldier decided to *desert* his dessert in the *desert*. 7) Since there is no time like the *present*, he thought it was time to *present* the *present*. 8) A *bass* was painted on the head of the *bass* drum. 9) When shot at, the *dove dove *into the bushes. 10) I did not *object* to the *object*. 11) The insurance was *invalid* for the *invalid*. 12) There was a *row* among the oarsmen about how to *row*. 13) They were too *close* to the door to *close* it. 14) The buck *does* funny things when the *does* are present. 15) A seamstress and a *sewer* fell down into a *sewer* line. 16) To help with planting, the farmer taught his *sow* to *sow*. 17) The *wind* was too strong to *wind* the sail. 18) Upon seeing the *tear* in the painting I shed a *tear*. 19) I had to *subject* the *subject* to a series of tests. 20) How can I *intimate* this to my most *intimate* friend? There is no egg in eggplant, nor ham in hamburger; neither apple nor pine in a pineapple. English muffins weren't invented in England or French fries in France. Sweetmeats are candies while sweetbreads, which aren't sweet, are meat. We take English for granted. But if we explore its paradoxes, we find that quicksand can work slowly, boxing rings are square and a guinea pig is neither from Guinea nor is it a pig And why is it that writers write but fingers don't fing, grocers don't groce and hammers don't ham? If the plural of tooth is teeth, why isn't the plural of booth, beeth? One goose, 2 geese. So one moose, 2 meese? One index, 2 indices? Doesn't it seem crazy that you can make amends but not one amend? If you have a bunch of odds and ends and get rid of all but one of them, what do you call it? If teachers taught, why didn't preachers praught? If a vegetarian eats vegetables, what does a humanitarian eat? Sometimes I think all the English speakers should be committed to an asylum for the verbally insane. In what language do people recite at a play and play at a recital? Ship by truck and send cargo by ship? Have noses that run and feet that smell? How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites? You have to marvel at the unique lunacy of a language in which your house can burn up as it burns down, in which you fill in a form by filling it out and in which, an alarm goes off by going on. English was invented by people, not computers, and it reflects the creativity of the human race, which, of course, is not a race at all. That is why, when the stars are out, they are visible, but when the lights are out, they are invisible. PS. - Why doesn't 'Buick' rhyme with 'quick'? AND If a male goat is called a ram and a donkey is called an ass, why is a ram-in-the-ass called a goose? No wonder we land on opposite sides of the land expropriation matter, not that it matters?
