This is the regularly made inquiry with respect to control inverters, and is the most hard to reply. The period of time that your batteries will last is proportionate to the span of the battery, the load of your inverter, what different loads are running from the battery and what charging sources are connected. Without knowing these factors our skilled technicians and engineers can’t give you an exact answer.

What we can anyway do is take a look at the power necessities of the appliances you intend to run, to what extent do you intend to run them and what other DC appliances will utilize the batteries.
