MMichaelK replied to the thread XW pro not running loads.Just because the generator is running doesn't mean the inverter is accepting power from the generator. With my XW+, the inverter...

MMichaelK replied to the thread Two mixed strings one mppt.Without additional space, here is what you could do. If you have only four of the 240W panels, wire one string with four of those. So...
-
MMichaelK replied to the thread Two mixed strings one mppt.Yes, as I suspected, you are comparing the Voc of one panel with the Vmp of the other. So, for the 240W string, you have 43.7V X 5...

MMichaelK replied to the thread Inverter recognizes generator but won't accept charge.Try first setting it a ridiculously low setting, like only 1-2A, then try ratcheting up the amperage incrementally. My XW6848 is that...
-
MMichaelK replied to the thread Two mixed strings one mppt.Not really, no, but your numbers are suspect? For panels in the first set, those appear to be standard 250W residential panels. For...
