Inverter Low Voltage Cutoff--Why SO low?
I''m planning to buy two 12V inverters: a small one (about 500W) and a bigger one (about 2000 watts). I want to protect my 2 x 105AH FLA batteries, but have been surprised to see that the low voltage cutoffs on inverters tends to be at about 9-10 VDC (often with an alarm starting at about 0.5...
