Ideal for large-scale, residential, and commercial solar power installations. Built with robust components, the PV combiner box includes circuit breakers and surge protection devices to safeguard your PV system from electrical faults and lightning strikes. Maximum voltage of 1000V DC and a maximum current per string of 15A. The enclosure offers an IP65 protection level. Ideal for large commercial and industrial solar power installations, utility-scale solar farms, extensive off-grid solar systems, residential solar arrays with multiple strings, and community solar projects.
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.
