Frequently Asked Questions
What are the main functions of a PV combiner box?
The main function is to converge the DC output of multiple solar strings into one channel, while providing protection through fuses, surge protectors, and circuit breakers to ensure system safety.
Is this combiner box suitable for outdoor installation?
Yes, the box is designed with an IP65/IP66 protection grade, making it waterproof, dustproof, and resistant to harsh outdoor environments and UV exposure.
What types of solar panels can be used with this box?
It is highly flexible and can be used with single crystal silicon, polycrystalline silicon, and thin-film solar modules.
How does the lightning protection work?
The box includes a professional DC Surge Protection Device (SPD) that handles nominal discharge currents of 20kA and maximums up to 40kA, protecting the inverter and panels from voltage spikes.
Can the components inside the box be customized?
Yes, while core components follow high standards, elements like the circuit breaker types or specific monitoring modules can be modified based on specific project requirements.
What is the standard payment term for orders?
Typically, orders are processed via T/T. For standard orders, advanced payment is required, while for larger projects, terms can be discussed regarding balance payments before shipment.
