The main ground-fault breaker (RCD) trips frequently.

Situation

Ground faults are being caused by electrical appliances, the KP100L, or the solar
modules.

Possible Cause

Remedy for User

1. Check to make sure that the ground faults are not being caused by electrical
appliances.
2. If no abnormalities are found, contact the store from which you purchased the
product to measure the insulation resistance of the KP100L and the solar modules. Also
describe the circumstances under which the problem happens (for example, the
problem occurs on the morning after a rainy day, etc.).
