  1. Right, crossroads, after a deep dive into Solis, to the brink of purchasing. NBEEF feedback: - 60amp breaker, will not sign off more than 3kw. - Panels will be earthed. - Batteries must be ventilated - they are in a wooden box - even maintenance free ones, AGM's too. - He does claim checks for select insurers. No CoC, no claim payout. Costs: - If all is ok with DB, about R1k to get a CoC - excluding fixes. - "The Engineer" ... I'll be back on that price. I'm smiling very broadly at this point in time. :-) I have: - BMV700, VenusGX, Trojan batts and all the cables. - 930w on a 150/35 in series (310w x 3) - 400w on a 100/30 in series (200w x 2) Additional parts required: - Carlo Gavazzi ET112 and a RS485 cable +- R1500 odd - New MultiGrid 24/3000/70-50 inverter. Worst case: R13 038.00 ex VAT. Plan: Want to push all solar power into the house, with a few select circuits like internet, computers, lights, fridge, 1 small freezers on battery backup. So will have the Carlo G energy meter installed after the main switch and before the earth leakage. As per Plonkster. As Plonkster pointed out: So, to max the controllers, yes, I know 24v has input limits, but Victron combinations do not. :-) 100/30 can take max 880w - currently on 400w 150/35 can take max 1000w - currently on 930w Total of 1 330watts. Run as is, see what the numbers look like after a few months. Assuming the numbers make sense, then BEST case thereafter: Get another 150/35 controller with 3 new 200w panels added to the exiting 2 x 200w = 1000w Get 4 new 220w panels on the 100/30 = 880w Plus the existing 930w array on the existing 150/35 = 2810 watts in total from 2 existing controllers, and 1 new. All the above on the assumption that ESS will allow this size array, on a small 24v 225ah bank. What am I missing?

    Anyone submitted an SSEG application to CoCT?

    Yes, that is the one. Mine is 99% complete, bar the spots that a sparky must test things. Like: - Electrical parameters of embedded Generation - Max peak AC short circuit current. - Circuit diagram ... ? - CoC. - And then the Compulsory Declaration - Engineer? That I know of ... Or am I missing the plot?

    Anyone submitted an SSEG application to CoCT?

    @Mark - don't laugh! It is serias stuff. A bunch of tests that must be preformed on the DB ... no jokes. IF anything is not on par, there you go, here is the quote, EFT so long ...

    Hold on a moment ... what form is that? Did you get a electrician in to test the stuff they want tested?

    Anyone submitted an SSEG application to CoCT?

    Welcome NigelL Nope, not that I am aware of. There is a trick though. Once you have the CoC, the engineer comes and check (I have contact details of one, send me a PM if you want), then the system is switched off, you need to wait for approval from CoCT to switch it on again. Can take a little while. They guys in Bellville are quite jacked though. So I heard form more than one source.

    Undersized inverter

    We have, and you are right, all of it. But that was before grid tied (feeding all the power into the DB board) like ESS software does. ESS takes grid / panels / batteries and cleverly balances it all by pushing all the possible power back into the DB when needed, even back into the grid if you want, this is optimal, pushing into the grid, but that has some T&C's. Or go grid tied like with a Solis and no batteries. That is THE cheapest approved grid tied inverter I know of, sending all the panel power into the house on demand. Even on a 1kw unit you start winning. So this changes everything, can now go smaller inverter and have more savings.

    Axpert 5KV+, Error 51, overload/surge

    Can happen to any of us ... All MAKES of inverters. Worst is when the power comes back after a failure. Circulars went around, even from insurers, to switch everything off after the failure and wait for it to settle before switching stuff back on. And we all had a lot of failures at one stage. Not that easy with DB connected solar systems (all MAKES). They take hits when the power comes back on.

    Axpert 5KV+, Error 51, overload/surge

    I have a question: Why did it happen: Age? Temp? Power surges? ... could it be all three? If it is power surges then can happen again and others could also be affected in due course, maybe. Ok two: And if they are replaced, is that it or could there be more parts affected that also needs replacing later? DIY is cool but asking from a non-DIY perspective: Is it worth to fix?

    Infini 3kw no batteries tripping on startup

    As you thought, put a UPS before the Axpert that the power goes Eskom / UPS / Axpert and see if that sort the problem. A UPS can handle much larger range of Eskom woes. If the UPS starts clicking at that time, or even takes the load over, then you know there is something "off" - pun intended. ;-) Just make sure that the UPS you do use, can handle the load at the time.

    Axpert 5KV+, Error 51, overload/surge

    A shot in the dark. On the forum there is also a Infini 3kw no batteries tripping on startup, no errors and the fact that the other night I had my inverter and a UPS switching 4 times due to Eskom. Assuming the inverter is not faulty and settings are right, what are the chances that Eskom is causing the inverter to trip - and not the heat? Any chance of putting test equipment on the inverter input / Eskom, to constantly read and record the incoming current, to see what came in when the inverter flips again?
  11. The Terrible Triplett

    Infini 3kw no batteries tripping on startup

    I would then look at the incoming power. Something in the area comes on, power dips at your house and your inverter reacts as designed. Your case, my case the other night and the thread about Axpert 5KV+, Error 51, overload/surge - could maybe all be related to Eskom. Mine was definitely Eskom. Maybe.

    Infini 3kw no batteries tripping on startup

    I missed that, apologies. Is it a daily morning routine, the tripping? Assuming the inverter is not faulty and settings are right, what are the chances that Eskom is causing the inverter to trip at that time due to voltage dips or some such? Could be an idea to put testing equipment on the inverter input / Eskom and see if you can eliminate the incoming power as the cause? (the technical guys can suggest what to use)

    Not that simply I'm afraid. There is on another solar forum a resident "expert" by the name of "Bill", before he took "over" a guy called "Caribocoot", before he got banned. ;-) It takes a lot of time to keep track of all that goes on, asking the right questions, giving the right advice, knowing all the quirks ... understanding the depths of solar making it newbie friendly. We are not doing to badly on our own.

    O, the guys I ask on Whatsapp, whom do reply when they can, after we have agreed my job is too small for them, for which I respect them for being that honesty, telling me straight, are too busy to be bothered with PF. I did ask them, seeing as they do help me now and then.
  18. The Terrible Triplett

    New Solar user

    I told them about PF and about potential business lying here, free for the picking. Not one of them are pro-Axpert. Not one. I picked that up after asking all of them repeatedly, for a Axpert specific solution, like the exact parts to use. They all go quiet, changing the subject. Also picked stompies up from a couple of them that they steer well clear of DIY installs. Few installers flatly refused to even quote unless they did the original install. Too many comebacks they say. Which makes sense. Some of the larger well known names, use contractors to do the actual install. And then there is the not wanting to get involved with DIY'ers in the sharing of their hard earned experiences, for free. Or giving advice / helping, just like insurance brokers whom are never allowed to help publicly, for it can bite them afterwards if things go wrong. Am finding the registered installers extremely ... uhm ... best word ... "arrogant"(?) ... it is like we don't need your business unless it is at Rx 000.00 per day. The entire team must come see. Then you get the guys at like Omnisolar. They bend over backwards to help, even in you did not even buy the part from them. Like Ontrack whom helped the other forumite, via Plonkster. Both of these companies have been around for yonks. My bet is a LOT of these "new" registered installers are not going to last ... when more sparkies get their teeth into solar. You know WHAT! Now that I think about it ... All the "sparkies" that I have been chatting to, they have real sparkies on their payroll!!! Every single one that I have met face to face, 2 guys pitch. One the smous / solar trained, the other the sparkie that is actually going to do the work. Sorry for the rant. I'm getting gatvol, just want to pay someone to sort some wires, maybe add a frame or two ... the reluctance for new business is staggering. 2-3 hours work tops at wot, R350-R450 per hour, parts excluded, for a proper install. Little to no interest from over 20 I have contacted. Most don't even reply.

    That sound is so cool, sounds "solid". APC's does a similar thing. Once I have this tripping sorted, as it is now an issue, man I'm gonna smile. APC can then be retired.

    Undersized inverter

    Ditto PLONK, that is what I mysefl was looking for!!! @Dylan my arrays combined are even smaller than Plonksters, and I'm negotiating with myself to add more panels or not, face the N/E/W ... the peak loads are kitchen, the evening loads the trick, whilst we are "negotiating" peak hours of usage, to move more to times solar performance is at it's peak. ;-) This should ideally be nicely curved, not jagged, if the use is constant, the smaller array being favoured, making me wonder if I need to move it to face East.

    Infini 3kw no batteries tripping on startup

    No idea how a Infini works, but seeing as the Blue team has a similar problem AND we also have 24v systems, maybe there is a common thread here? Our DB's are tripping because of the collective mA's on the circuit that are exceeding the Earth Leakage limits. Maybe you are in the same boat? What comes on after 7am? Can you stop that, wait till say 7h15, then switch on what normally goes on at 7am?
  23. The Terrible Triplett

    Crit my idea ... pull it to pieces, I can take it.

    Yes, mA, not mV - my bad. Consensus seems that it is because SABS is not testing stuff anymore, therein this problem, cheaper and cheaper stuff arriving on our shores - not that we pay less that is. My first port of call is to feed a online APC from the MG DB, and APC feeds the rest. If with the APC the MG DB does not trip, then I can trace the components easier and safer, with the least amount of interference, till I find the culprit/s. Because each time I "fix" things, touch wood, SOMETHING goes wrong ... (facepalm). Ok, let me go and think this thing through, one plug at a time ... they say. If I/we sort our quirks, we would have learnt a LOT! @plonkster One question: To trigger the MG to go into UPS mode, what is the best way? Switch off the mains supply to it?

    Undersized inverter

    Hi Dylan, welcome. I have a Multigrid 24v, brand new, but basically the exact same scenario as you are questioning. The costly part of your bill is not the kettle or stove, it is the loads that are on 24/7/365. They tend to be below 1kw. And the part we tend to forget, the loads that are on when all are asleep, loads that are not needed. And the last part, when are the loads used, like stove, late afternoon, early morning or evenings? Let me give you my take: - Is it worth the cost to go bigger inverter to cover a kettle on for 3 minutes each time it is used? You can get a 1kw / 2kw kettle if you want. Just takes longer to boil, same power usage. - Stove. With ESS the big watts are off-set with all the panels can give, so you are saving (cents) each time it is used. - Geyser, put in a smaller 2kw element, and a timer or whatnot, that it draws at the time the inverter is idling, and not when the stove / kettle is on. ESS is the perfect balance to use all the power the panels can provide, and by staggering the loads evenly, you save even more. That is why one can use a smaller inverter and enjoy the best usage of solar power. Flip side: Go big inverter, lots of panels - and batteries - and cover all the PEAK loads that we tend to worry about, loads that are on for probably less than an (fill in time) ___ per day, or loads that probably are on in the evenings, which needs batteries, or Eskom. Batteries, where Eskom is available, with optimal daytime use of appliances, is more expensive than Eskom. Another thought: If you are Cpt based, EV tubes are more efficient in winter than any PV panel. It could be an interesting idea to check out a EV tube system for ones geyser, than adding more panels or bigger inverter, for geysers do use a lot of power.

    One sparkie came back, he says reputable suppliers like Rubicon has the new cables as per new regs.
