Frequently Asked Questions
What is the primary function of a PV combiner box?
A PV combiner box consolidates multiple DC inputs from solar panels into a single DC output. It protects the system by housing necessary safety components like fuses, surge protectors, and circuit breakers.
Does this combiner box support lightning and surge protection?
Yes. The box comes equipped with a PV-dedicated Surge Protective Device (SPD) to defend your system against lightning strikes and high-voltage surges.
Is the combiner box suitable for outdoor installation?
Absolutely. It features an IP65 protection rating, which means it is completely dustproof and highly water-resistant, making it perfect for harsh outdoor environments.
Can I monitor the status of individual strings in real-time?
Yes, we offer an optional current monitoring system for each string. Combined with the optional RS485/Modbus-RTU interface, you can monitor parameters like voltage, current, and temperature remotely.
What is the difference between On-Grid and Off-Grid configurations?
On-grid configurations are designed to coordinate with high-voltage utility grid tied inverters. Off-grid configurations focus on directing combined solar energy to charge controllers and battery banks for independent power storage.
