When your inverter has a red LED on, it means something is wrong. There could be several issues. Most installations are connected via the Internet to the inverter manufacturer’s monitoring platform.
On a rainy day it is best to wait until the weather improves, if the malfunction is gone then your installation is dealing with an insulation fault. In that case, please contact Eco Technics.
If you do not notice anything abnormal right away and the inverter fuse is on, it is best to contact Eco Technics.
