UK homeowner reports solar battery flooding in garage

A homeowner in the United Kingdom reported flooding in their garage that reached the level of their solar backup equipment. While the main solar system was shut off at the isolators and fuse board, the resident expressed concern that a Growatt battery may have remained powered on due to cable obstructions preventing the manual shutdown.

Online discussions regarding the incident highlighted that IP66 ratings do not protect equipment from submersion. Experts suggested using fans to dry the unit thoroughly before attempting to restore power to mitigate damage from moisture.
