Powerwall+ inverter has rainwater dripping in after storms
Rainwater gets into the Powerwall+ inverter after storms, coming down the conduit from the roof, sometimes with a loud cooling fan and solar dropping to zero for minutes. This page covers what to check first and the cause behind it.
What to check first
- After rain, look for water coming into the inverter's top port from the conduit that runs down from the roof.
- Note whether the inverter's cooling fan runs loudly for most of the day, and whether solar drops to 0 kW for several minutes at a time.
- Take pictures of any water that has drained into the inverter and send them to Tesla.
- Ask Tesla or your installer to inspect the conduit run from the roof and the fittings along it.
