Installed a 10kwh battery to my 7kwh solahart panels. Installation went smoothly. App now includes battery information.
10kwh won’t be enough to survive off the grid, but will save us money.
We chose to include our air~con circuit on the battery backup as we don’t have many blackouts where we live… and when we do, power is usually back on within a couple of hours.
Battery is usually full by 10am (in Nov on sunny days in Newcastle) and discharges overnight to the 10% minimum. So I can calculate that our savings at present are around 9kwhs per day + a little extra saving when the battery contributes to our power usage during the day when our usage exceeds the power delivered by the panels.
