What is a solar combiner box?

A PV combiner box combines multiple strings of solar panels into one main output circuit. It''s essential for any solar installation with multiple strings as it provides overcurrent protection, surge protection, and circuit isolation, ensuring the safety and efficiency of your solar system. How do I know which voltage level to choose?

How does a solar combiner work?

Each string consists of solar modules wired in series, and the combiner box gathers multiple strings into a single output while ensuring safety and system efficiency. Current Collection: Consolidates DC output from 6–24 strings into busbars. Circuit Protection: Prevents overcurrent, lightning damage, and reverse current.
