Hi Folks:
I got the Victron MPPT 100/30 and the 24v EG4 LifePower battery. I have 3 Solar Panels Q.PLUS L-G4.2 330 (datasheet attached). I'm trying to figure out the best configuration for the voltage and the way to connect the solar panels. The options I see are:
1 - Connect them all in parallel. The Voc is 46.5 and Vmpp is 37. The battery charging voltage is 29V. While this is close I'm assuming this should be fine for the MPPT to work.
2 - Add a fourth panel and use then into 2S2P (2 serial and two parallel). However I would be going over the solar capacity of the MPPT of 880 watts by a large margin as 4 panels would be 1320 watts.
3 - Replace the charge controller with a Victron MPPT 150 / 35 use them all in series. More opportunity for shading and power loss.
I'm leaning towards 1, but would like to check on the wisdom of the group.
Thanks
