Frequently Asked Questions

Expert Insights into Solar DC Protection

Why do I need a combiner box for my solar PV system? +
A combiner box consolidates multiple DC strings from solar panels into a single output for the inverter. It provides essential protection (fuses, SPDs, breakers) and simplifies system maintenance and wiring.
Can ShineTong customize the combiner box configuration? +
Yes. As a leading manufacturer, we offer full customization. You can specify the number of inputs, voltage ratings (600V/1000V/1500V), and additional features like monitoring or specific connector types.
What is the standard lead time for wholesale orders? +
Standard configurations are usually shipped within 7-14 days. For large-scale customized orders, our factory ensures a fast turnaround time of 3-4 weeks.
Are the components inside TUV or CE certified? +
Absolutely. Every critical component inside a ShineTong combiner box, including the SPD, fuse, and breaker, carries its own TUV or CE certification to ensure maximum safety and compliance.
