So, all hypothetical of course.
I have a 48v completely off grid system, comprising of a 1000w inverter, 4kw battery and a 150/35 charge controller. Lets say I am pulling 700watts sustained from my inverter. Could I THEORITICALLY plug in a cheap "grid tie" AC inverter from some small solar arrays to supplement the load? I.e. if I add a 300w micro inverter downstream of my DC inverter, then my 700w load becomes 400w on the DC side? (roughly, obviously some minor losses). As long as there is a sustained load on the AC end, there should be no risk of back feed?
Thanks!
