the problem: i didn't read the 'fine print'. just picked up 2 stackable 2500 w modified sine inverters and one 6000w pure sine inverter - i was on a roll, what can i tell you... tax return giddiness. anyways, turns out this 6000w inverter can't be used when the PVs are charging the batteries, it will only act as a battery charger/transfer switch via AC power.... not a HUGE issues since this is for a remote cabin, so i can unhook the inverter when i leave and let the solar panels charge the batteries (12 x 6v golf cart batteries wired as 24v so way more power than i need for a long weekend)... HOWEVER so i don't have to mess with hooking and unhooking stuff when i leave, could i use the 2x2500 watt inverters connected to the solar panels (via a charge controller of course), with a bank of 4x6v batteries, with the ac cable to the IN on the 6000w inverter? technically sounds like it would work, but just seems like there has to be an easier way... maybe simply shutting off the inverter when i'm using it and turning ON the solar panels (i built a charge combiner with breakers) when i leave?
