* When installing this system in high humidity locations, install using ground fault equipment breakers (often referred to in other countries as an ELCB earth leakage
current breaker) to reduce the risk of leaking current which may result in electric shock or potential fire. We suggest installing GFEB breakers or follow local
electrical code. This system uses an inverter, which means that when used with a ground fault breaker you must use breakers that can handle higher harmonics
such as a (GFEB) Ground Fault Equipment Breaker (30 mA or greater) in order to prevent malfunctioning of ground fault device.
