Frequently Asked Questions
Plastic or metal PV combiner box — which should I choose?
Plastic boxes are lighter, fully corrosion-resistant and ideal for residential and rooftop projects. Metal boxes provide greater mechanical strength, better heat dissipation and are common in utility-scale and harsh environments such as desert or coastal sites.
What system voltage do your combiner boxes support?
We offer both 1000V DC and 1500V DC versions. 1500V DC is now the standard for utility-scale PV due to lower BOS cost.
Do combiner boxes include SPD, fuse and breaker?
Yes — our standard combiner boxes are pre-assembled with DC fuses, DC SPDs and DC MCBs. The configuration is adjusted to match your project single-line diagram.
Do you provide drawings and BOMs for tender packs?
Yes — we provide CAD drawings, single-line diagrams and BOMs in formats suitable for EPC tender submissions and engineer review.
What is the standard IP rating?
Standard rating is IP65 for outdoor use. IP66 is available on request for harsh environments.
