Hello
I am planning to use 7 panels in a 5kw Easysolar Controller.
Configured as 3 panels in series, 40Voc 385W panels on the 150/100 Easysolar controller
Then 4 x 40Voc 385W panels on a separate 100/35 Controller in 2 x 2 Parallel in series with each other 2p2s configuration.
The reason being that 7 panels n series would be too hight for the Easysolar Controller so i need a second MPPT controller and the 4 panels in series would be 160V. I don't want the voltage to be that high for safety reasons and the 250V controller would be £500 instead of £250.
My questions:
1. Is it ok to put 2p2s configuration together?
2. Will the MPPT function of the controller work efficiently with 2p2s?
3. Should I use any shading diodes in either String 1 (3s) or String 2 2p2s.?
thanks very much for your thoughts.
