Off Grid Home Forums Technical Discussion Power Usage Re: Power Usage


re calculations on batteries, not quite correct – any off-grid living system should be on 2 volt cells (deep cycle) (always check the cyclic capacity as this will give an indication of the life). Discharge ideally down to 50% depth of discharge (dod)any lower than 80% will kill the battery. After installing these for last 10 years, there is no average system, but based on lifestyle and usage size can vary between 24v and 48v and 1200Ah to 2000Ah. Using 12v monoblocs (leisure batteries, car batteries, truck batteries) etc on any domestic installation with a large inverter can be false economy.
