Sorry that is to hard to understand for me. You can not describe it in a way so even not experts can understand?

Please tell me what this means: Full power MPPT voltage range

I can not see anything about optimal voltage in manual

I contacted Sofar about this question. They say: PV1 and PV2 can operate at different voltage levels so there should be no problem. Can you show documentation about "same string voltage"?

My idea is to do like this. I will take away the 8 panels on south roof and place them on the other three places. Then I will try to find a new panel that is very good. Is Longi LR7-72HVD 625-645 the best to find. Please help me to find the best. Important that the panel should be good when weather is cloudy. Then I will install 17 of that one on south roof, 3, 5 and 9 Then it will be on Slave 9 south + 10 east. Master 17 south roof +10 west Someone told me that it have to be the same number of panel on the 2 connections on each inverter Especially on Master that will be a big difference

So it is like that, you can not mix panels, the least good will be the result I looked at your link to Lazada. price was 2,640 then I saw promotion and 2 prices 560 and 450. What does it mean?. Can anybody tell how good this panel is? Better than my old? As good as Longi? That means I have to change everyone to get better data?!

Hi, I have an off-grid system at Hua Hin I have 2 Sofar 20kW inverter, they are set in parallel 17,5 kW battery to each inverter 30 panels Suntech STP545S-C72 Slave inverter have 8 south panels in serie to MPPT1 7 east panels to MppT2 Master have 8 south panels to MPPT1 and 7 west panels to MPPT2 My system has been working for 3 years and I don't think i can add more batteries My idea is to add more panels. Because the system needs more power I heard from a person that I thin know what he say, Longi LR7-72HVD 625-645 is a very good panel He give me a price of 2,700 baht, I don't know if it is possible to find a better price He said that when it is a cloudy day, my panel only gives 5%. Longi gives 30%, and even the max output is 15% higher So my idea is to add 1 to the 8 on carpark 3 to the 7 on east side of roof 9 to the 8 on south side of roof And 3 to the 7 on west side of roof. This should be 16 in total on Slave that should be 9+10 Master 17+10 Now I wounder, as being no expert, should it be ok to do like this

Could the reason be that the pump have stopped but the cell have been working, and the chlorine have affected the pvc tube and some material detached and stuck on the cell?

Interesting! So this is 4 inverters. And this information you can see in picture in your program? I wounder if I can see that too in my Solarman business? I think I will see if I can find a manual "throttled right back," Which means? Attach a picture of my electric central. Made by a former colleague of me that let build this house. Little unusual in Thailand I think

The reason for 2 inverters is the electric car ;-). The big charger is for 32A in 1 phase and that is maximum for the inverter. And as we have a 3 phase house there are many things on every phase Expansion of panels? the problem are the batteries 35 kW, too little and they are expensive and the say I can add more because the problem to align them to the old. After 6 months I was successfull to add 4 to the 10 I had. So that is the reason why I try connect to PEA, sell power and buy power when batteries are low. "If there's nowhere for the energy to go it won't get made." Please explain

Thanks for the link, I hope I will understand! Nothing shading! 1 group on roof of carport (slave inverter), 1 group on house roof (Master inverter). Inverters connected in parallell to get 64 A load on each phase Both absolute south orientation I never heard of maxing out inverter (Sofar HYD20KTL-3PH), is it possible and how to do? Info in manual? I don't know how to see the dayly effect on Solarman Business. Is it possible to see on each connection? On Slave I have PV1: Carport 8 panels in serie, PV2: east 7 panels in serie On Master I have PV1: Roof house south 8 panels in serie, PV2: west 7 panels in serie

Is there a table for this or can anybody help me? I have 8 panels on 2 places towards south and they give very different current, about 20% difference. I don't know the inclanation of them, will check today. Either the differnce in inclanation gives the difference or a problem have ocurred

It was installed by a PEA registered company and material was approved too! <Note by Crossy> Fixed the reply, it was inside the quote

How do you know this is not installed by a pea approved installer using pea approved equipment?
