What you will see
- Error 201 Residual I High
- Inverter drops off on humid or rainy days

- Note the weather when it happened
What not to do
- Do not keep restarting
- Do not touch panel frames or cables while the fault is active
When to call us
- Insulation test AC and DC cables
- Check earthing
- Raise a warranty case if the sensor is faulty
