My 2022 GD Reflection 28bh came with a Grape Solar 370 Watt panel from the factory and as im looking to expand the system it is proving to be a bear to add additional panels, efficiently. I'd like to avoid replacing the existing 10awg from the roof to the controller up front so expanding in series made the most sense at first, however I don't have room for 3 of those 370w beasts and we camp in the woods often so the shading effect of all panels in series makes me nervous. So here's where im at, SERIES-PARALLEL, please let me know what you think. There's lots of theoretical information out there to consider in a setup like this so please double check my work! If you think it's a good idea, then I got lots of inspiration from folks on these forums and Nate over at Explorist.life (Check them out if you haven't, TONS of great info). If it sucks, then it was my idea, i'm the only one to blame.
The 370w Grape is what I already have. They won't ship a panel to me, said the packing for freight would cost 500 bucks before the price of the panel! I found this Furrion 370W gen 2 from Lippert and while it's expensive, shipping is free. The Newpowa 200W panels I found from BattleBorn with free shipping. These panels were designed to expand 24v systems which makes them look to be a better match to expand my system. Anyways, let the darts fly where needed!
