1.Do I need to clean my solar panels?

Solar panels do self-clean based on the angle. It is recommended to clean between 1-2 years as dust and bird droppings may build up over time. Use a soft cloth to wipe them down or you can hose them down.

2.What do I do when my inverter is not working?

First, check power supply. If it is working, try turning off your inverter as per the shutdown procedure. Ensure the solar supply switch is in the “on” position. If these steps have not fixed the issue, please contact us or refer to your system’s online manual.
