    FAQ

    Q1. What can cause the circuit breakers to trip frequently?

    Frequent tripping of circuit breakers can be caused by overcurrent situations, faulty PV strings, or a short circuit. Inspect the PV strings for any faults or damage and ensure the current from each string does not exceed 15A.

    Q2. How do I reset a tripped circuit breaker in the combiner box?

    To reset a tripped circuit breaker, switch it to the "off" position and then back to the "on" position. Ensure there is no underlying issue before resetting.

    Q3. What should I check if there is no output even when all connections are correct and breakers are not tripped?

    Verify the integrity of the surge protection devices and inspect for any visible damage. Ensure the output cables are properly connected and check the overall system voltage compatibility.
