Q1. How does it contribute to system safety?

The combiner box plays a crucial role in system safety by providing overcurrent protection (through fuses or circuit breakers) for each solar panel string, thus preventing potential electrical fires. Surge protection devices also protect the system from voltage spikes caused by lightning or grid disturbances.

Q2. Can it accommodate different types of solar panels?

Yes, it can accommodate different types of solar panels as long as they are within the voltage and current specifications of the combiner box. It’s important to match the electrical characteristics of the panels to the combiner box’s specifications.
