A1:The hybrid inverter is not working. The screen is not showing
anything.
Q1:For this situation, there are 3 things to check:
(1)Check for loose, broken or corroded connections in the cables
between the inverter and battery bank.
(2)Check the fuses/breakers in the combiner box.
(3)Verify battery voltage is sufficient to power up the inverter
A2:Everything is hooked up correctly. The sun is shining directly onto
the solar panels but no charge is going to the batteries.
Q2:Check the voltage of the battery bank. The battery bank is most
likely fully charged and the solar charge controller inside the hybrid
inverter has disconnected the solar panels from the battery. The solar
charge controller will reconnect the solar panels to the battery bank
when it requires charging.
The following maintenance is recommended to ensure optimum perfor-
mance and longevity of the solar panel:
• Clean the glass surface of the solar panel when necessary. Always
use water and a soft sponge or cloth for cleaning. A mild, non-abrasive
cleaning agent can be used to remove dirt.
• Check the electrical and mechanical connections every six months to
verify that they are clean, secure and undamaged.
• Inspect the solar panels and make sure the surfaces are free from
dust, dirt, and other debris; clean with a wet cloth or glass cleaner if
necessary.
