Solar PV Combiner Box Manufacturer - 4-16 Strings, 1000 V DC
DC combiner boxes that collect the output of multiple PV strings into one DC output, with per-string fuse protection and surge protection, for commercial and utility solar installations.
- Per-string protection — every string input is fused individually.
- DC surge protection — surge protective device fitted on the output side.
- Two voltage classes — DC 1000 V standard, DC 1500 V for utility projects.
- Metal or insulated enclosure — steel or SMC/PC enclosure to order.
- Monitoring on request — string current monitoring can be integrated for SCADA connection.
