Salam, hope everyone is doing ok. I am planning to upgrade my solar system in coming months so I need some suggestions from you guys. My current system is:
6*295w solarworld panels, connected as 2 parallel arrays of 3 panels in series.
3kva axpert inverter with 48v battery bank of 4 AGS 200 Amp Hour batteries.
So my future plan is to buy infini 3kw plus model and add 4 or 6 more panels of 350watts Solarworld as I cannot find the 295watt panels now in the market. The short circuit current of these new panels (350watts) is the same as the old 295watt panels I have, so I believe I can wire them both in series.
So here is my plan:
Buying 4 or 6 of the 350watt panels and make two arrays in parallel. Each array will be 3295watts panels plus 2 or 3 350watt panels in series.
The spec sheets of both type of panels is as following. Kindly advise me should I go for 4 of the new 350watt panels or 6 of them.
Rated max power 295w 350w
Open Circuit Voltage (VOC) 40.0V 47.3V
Rated Voltage(Vmpp) 31.5V 37.8V
Short Circuit Current (Isc) 10.10Amp 9.82Amp
Rated Current (Impp) 9.45Amp 9.29Amp
Any response in this matter will be highly appreciated.
