Growatt error 201: Leakage current too high
Growatt error code 201 usually means the inverter has detected leakage current that is higher than the permitted safety limit.
Leakage current faults are designed to protect the inverter and electrical system from unsafe operating conditions. When this happens, the inverter may stop producing power or disconnect from the grid as a safety response.
This type of fault may be linked to insulation problems, damaged DC cabling, moisture ingress, faulty solar panels, grounding faults, inverter hardware issues or another electrical fault within the system.
In some cases, the issue may appear after heavy rain, high humidity or ageing components within the solar installation.
Book a solar inverter check with e-Solar
If Growatt error code 201 appears once and clears after a restart, the inverter may have detected a temporary condition. However, leakage current faults should not be ignored if they keep returning.
If the code keeps appearing, your solar production has dropped, or the inverter is shutting down repeatedly, it is worth having the system checked.
Our Perth solar experts can inspect your inverter, solar panels, DC cabling, isolators and grounding system to help determine whether the issue is linked to insulation resistance, moisture-related faults, damaged wiring or another system issue.
Contact e-Solar and let us know:
- The exact error code on the screen or app
- When the code appears
- Whether your solar production has dropped
- Your inverter model, if you know it
Do not open the inverter or attempt electrical testing yourself. If the issue is persistent, a qualified technician may need to carry out insulation testing, leakage current testing and a full system safety inspection.
