  1. Seems like I missed out on a great Discussion sofar many valid points mentioned sofar.. however the most important thing for me is what happens after the warranty is over will I still be able to have my Pylontech / Hubble /Blue Nova / Revov etc serviced repaired or refurbished?
  2. Wow that does look very nice and neat
  3. Please substantiate you comments with proof @Brani you are an installer and have hinted that on many occasions.. you are not an consumer and have many times indicated to us that you claimed to have vast knowledge when it comes to solar power and batteries .. however I will not further waste my time as it is not educational nor productive and I don't argue for the sake of Argument..
  4. Lol Leshen has been a member longer than you have buddy almost as logical as your Pylontech argument.
  5. Segen Solar does not sell directly to the Public do they ??
  6. Well from a budget point of view C rating is Important especially in a off grid Scenario I have 2 x Hubble 5.5 KW batteries I have a 5 KW Sunsynk I run my whole house including my Geyser off my system So my Peak loads can Exceed 4.8 KW at certain times and I have to manage my loads I paid the Special Price of R24700 each for my batteries for 11KWH R49400.00 the two batteries combined can deliver 9.6 KW Max my inverter can demand is 5KW so even then I would loading my batteries at just over .5C when recharging with solar power I have the same scenario Which Means I will never cycle my batteries at 1C which means a Hugely extended lifespan from a cost perspective 3 x US 3000 C Batteries would have cost me R18750.00 VAT Included Each R56250.00 and I would've had 9.975 KWH and max continuous discharge and recharge of 5.328 KW Which is .5C of a battery that is so called a 1C Battery where my Hubbles can do 9.6 KW the Pylontech's Can only Sustain a 1 C Discharge or charge for 90 Seconds However this means the Pylontech batteries would be working at maximum capacity or close to it the whole time where the hubbles would basically be idling I have monitored and measured my system and My Hubbles give me around 12 KW Hour useable power and it has been improving over time. Now form a Cost perspective the Pylontechs cost me a lot more for a lot less Useable power and they would have been running at their Maximum Output for a lot of the time. Besides I am adding 2 more Hubble 5.5 units this reduce the load even more on my batteries and extend their life even more so for me the choice was easy and logical Price Difference of R6850 and I could use Decent battery cable 50mm2 covered the cost of a couple extra panels..
  7. The Sources of your Pricing is very Inconsistent I have not been able to Find a US3000C for R16100 Vat included anywhere So just on your 1st calculation on the US 3000C the best online Price I could find was R16699.94 and the Price per KWH is R5022.53 Per KWH The Up 5000 with its 5 year warranty is R4797.18 and that is the price on the power forum store also clearly it looks like you have your knife out for Hubble Besides the new specs on the BSLB batteries are all supposed to be 100% DOD however no stats available on what cycles you will get at 100% on those another point is the 3000 Cycles that the Hubble battery gets cycled at has to be 1C discharge and 1C Recharge and you will achieve this on a 5KW inverter if you try hard what I aslo know is that after you cycled the Hubble 3000 Cycles at 1C it still retains 80% of its original capacity which is 4400 Watt Hours and then you can discharge it at 1C and recharge at 1C 100% dod and get another 3000 cycles what does it say about the other brands how much capacity is retained after its 6000 Cycles and will it give another 6000 cycles at the same C rating and DOD ? Would be interesting to know..
  8. This is very bad news ..... had a friend that wanted a couple of these what caused the store to drop the special ?
  9. Would love to see those price comparisons price per watt linked to warrany
  10. Hubble Lithium s-100 12v 1.2KW 100% dod batteries on the forum store for 5k each vat incl Estimated average solar production is Rated Solar power of panel @ 5 hours per day..I oversized by 100% panels are cheap.. Roi for me is over 25 years as I am off grid and works out to R24 per month... Sizing your system correctly is important that includes batteries to get you through cloudy days.. www.powerforum-store.co.za a great option..
  11. Simple Answer get a Sunsynk or True hybrid inverter system.
  12. I can Recommend the www.powerforum-store.co.za very good prices great service and great advice worth it.
  13. Deye and Sunsynk inverters are two seperate brands I assume Deye for firmware updates your installer has to request that from Deye. Freedom Won can get complicated best you contact Freedom Won directly for support or get your installer to sort it out.
  14. My Recommendation is get a decent electrician you have bridged neutrals in your setup somewhere like a light pullining a neurtral from a plug...
  15. You Could look at the Riot cloudlink No monthly fees and works with most of the nex Axpert Clones https://www.riotsystems.cloud/
  16. Then Your best option is either the bull or the hubble I saw the powerforum store has a special going on the bslb 10.2KW and based on your loads 3 would do the job very well
  17. My Recommendations would be if I understand your terminology correctly you have a 700 Watt base load and a 1.5KW peak load not KVA as that is calculated with a power factor.. So based on that premise you can do the calculations as follows Load 700 Watt runtime 4-6 hours lets work on 6 6 x 700 watt =4200 watt this tells us you need a battery that can store and produce 4200 watt of useable power so the battery you can look at is a BSLB 6.4 KWH or a Hubble AM2 5.5 KWH the Bull has a theoretical capacity of 6400 watt @100% dod and the hubble 5500 watt @100% both batteries are 1C which means they can charge and discharge at their capacity 125 amp @ 48v for the Bull and 115 amp @ 48v for the Hubble you may use a little additional capacity for the peak load of 1.5KW but its negligible. Now for the Choice of the inverter.. Your Continues load of 700W and peak of 1.5KW dictates a small inverter but will limit you to expanding your system so the recommend system and this is based on value for money is a 3KW Axpert clone inverter but they have a lot of limitations 1 MPPT limited solar power short warranty 2 to 3 years and they are basically designed as battery backup solutions or you Could look at a True Hybrid inverter like a Sunsynk Solis Kodak or Goodwe all are decent hybrids 5 year warranty you scope or aim will dictate what you need also note any 3kw Axpert inverter is 24v and not worth wasting money on the Kodak 3KW Hybrid as an example is 48v and will work with the suggested batteries they also have duel 500v MPPTs which is more flexible however a 5KW Sunsynk is probably going to be your best choice.
  18. Pylontech works but you need atleast 3 x US3000C batteries for a 5KW inverter Hubble AM2 is 5.5KW 100 amp and you need one good battery I have 2 and BSLB Bull 6.4 is good there you will just need one but if you have budget limitations then You could also look at the Hubble AM3 2.75 KW or the BSLB Bull 5.1 KW.. withe neither of these will you have potential warranty issues with minimum battery requirements that some Pylontech suppliers enforce.
  19. Your Configuration on your strings are wrong 3 x 360 watt panels will have no meaningful production because of the low VOC so I would move 3 panels to the north roof and add another string of 6 or 8 panels facing east or west you can also add a third string using a small grid tie inverter on the Aux port of the sunsynk Facing west of around 2.5KW.
  20. The Guys at Riot are in constant state of development as far as I know you will get charge discharge rates capacity and so on from Pylontech and some basic Info not as detailed as the Hubble apparantly Pylontech is very protective on their code for their BMS etc the version of Riot Iam getting comes with a very accurate 3 phase meter that can be used to remotely monitor loads in stand alone mode and the Sunsynks MODBUS code will be added too it soon so I will be able to get far more accurate readings from the inverter and battery. So yes it will work with Pylontech but with more limited information on the battery.
  21. @Vassen I am not too concerned about Hubble being around in the next 10 or 20 years it is Local yes and as far as I know they have roots and support of a company thats been around longer that Segen solar GC Solar and pylontech and other brands the positive aspect is that they offer good after sales service and they are continously developing new tech on their batteries and I support local cause its lekka..
  22. I agree with you however I am getting a RIOT in place soon that will give me more accurate readings and a little more in depth information that one can analyze the true performance and losses. Give your system some time it may improve as mine did.
  23. Hi @Saul Seems very strange I have 2 x Hubble AM2 Batteries with a theoretical Capacity of 11KW or 11000 watt if you look at this screenshot of solar man you will note my battery was at 46% Capacity which is theoretically 5060 Watt left in the battery My system Recharged 6700 watt into the battery you can see it clearly on the screenshot this means either my battery has a larger capacity than 11 000 watt if you add 5060 to 6700 watt then we get 11760 watt However I must admit when my batteries were brand spanking new I only got 10 000 watt out of them the problem is each installation has its own factors that can affect efficiency and so on your inverter may be slightly less efficient or your batteries need more time to "run In" whatever the case may be I am very pleased with how my batteries have been performing for the past 3 Months sofar.
  24. Then I would rather go for the BSLB POWER WALL 10.2 KW check the forum store they have a special on it we all know its a reasonably good product..
