Gree E5 error code: overcurrent and supply voltage protection

Gree assigns E5 to an overcurrent protection trip. The control has seen the compressor circuit draw more current than its limit, and Gree links this to a supply voltage that is too high or that sags and swings under load. It points at the electrical supply, the connections, or the compressor and its drive rather than one named part. Applies to: Gree residential mini-splits that publish E5 in the protection code family This reading follows the Gree code overview and service literature for the residential mini-split families that publish E5 as a protection code. Other Gree ranges and other brands can map these characters differently, so match the indoor and outdoor model plates first. Owner-safe checks: Note whether E5 trips coincide with other large appliances running and whether the lights dim when the outdoor unit starts. | Check that the isolator switch by the outdoor unit is fully on and shows no scorching or a burnt smell, without opening it. Qualified technician: Measuring supply voltage under load, checking the feed size, inspecting energised connections, and testing the capacitor, contactor, and compressor current require a qualified technician or electrician.
