TCL error code P0
What it means
High voltage protection.
Possible causes
Supply voltage exceeding design limit Wiring errors at isolator or distribution board Surge or transient overvoltage
Suggested fix
Measure supply voltage profile, correct wiring and site power configuration and install appropriate surge protection; replace damaged inverter or protective components before re-energizing the system.
Safety first. Isolate the power supply before inspecting any unit. Refrigerant-circuit
and electrical repairs must be carried out by a qualified, registered technician.
