1. If the indicator flashes red, wait for 30 seconds to see whether the fault will be corrected automatically. If it is corrected, then no further action is required.

2. If it is not corrected, then press the power button once to manually correct the fault.

3. If this does not correct the fault, remove the input and output cables of Solarbank E1600 and turn it off and then on again. Next, troubleshoot based on the following possible conditions:

 If the indicator still flashes red after the restart, the fault may stem from Solarbank E1600.

If the indicator no longer flashes red after the restart, the fault may stem from the photovoltaic panels or the microinverter. To determine the exact cause, connect Solarbank E1600 to only the microinverter or only the photovoltaic panels, and check if the indicator still flashes red to identify whether the fault is coming from the photovoltaic panels or the microinverter.
