iStore error 2077: Off-grid output overload
iStore alarm 2077 usually means the off-grid output is drawing more current than the inverter is rated for, or there is a short-circuit condition.
This can happen if too many loads are connected at once, or if an inductive load causes a temporary spike. The inverter may stop supplying power to protect internal components.
Check the off-grid load and inverter output safely
Power off the inverter before inspecting the output (turn off AC and DC switches) and follow safety label instructions. Verify that no connected devices are short-circuited and that the total load does not exceed the inverter’s rated output. Adjust the connected loads as needed to prevent overload.
