I have an older (installed in 2015) 400 watt solar installation on my motorhome which uses 4 100Watt Grape Solar GS-STAR-100W (VOC 21.9, ISC 6.13), I have also recently acquired a number of very lightly used 305Watt LG NeON (VOC 40 ISC 10.1) panels from a hurricane damaged installation, that I would like to re-use along with Victron 100/50 MPPT solar controller for this upgrade. My issue is that I only have enough rooftop real estate to fit 3 of the LG NeON2 panels due to vent / skylight / antenna placement. I could however additionally fit 2 or possibly 3 more of the 100W Grape panels in smaller open spots around the roof.
Which leads to the mix and match potential options, and do you think it will work:
3 LG panels in parallel (VOC 40) along with 2 Grape panels in series so as to get a VOC of 43.8 on the Grape panels?
2 LG panels in series (VOC of 80), paralleled with 1LG and 2 Grape panels in series for a VOC of 83.8 combined for all 3 panels?
Will this not work at all, should I just live with only 3 LG panels, and only go from 400 to 615 watts of panels on my upgrade,...?
p.s. correction they are LG NeOn not NeOn2, ISC and VOC has been corrected above
