PV Combiner Box
For grid-connected photovoltaic projects that need AC distribution, metering, combiner or grid-connection protection between inverters and the grid side, when the project needs a project-ready grid-connected PV equipment with PV capacity configuration of 100-250 kW. What it does:
PV Combiner Box collects, distributes or connects PV system output while integrating switching, surge protection, metering and enclosure options according to project scale. It supports voltage options including 690V AC, 400V AC and 690VAC. The product is positioned for procurement teams that need clear model selection, technical confirmation and export project coordination. Why buyers choose it:
- Available PV capacity configuration of 100-250 kW helps match common project loads without changing the product family.
- Selectable voltage options including 690V AC, 400V AC and 690VAC supports coordination with site distribution systems.
- model reference 100 / 150 / 200 / 250 kW, IP65 protection gives engineers a clear basis for technical comparison and specification review.
- The product can be coordinated with Longxiang switchgear, transformer, new-energy equipment or project accessories for packaged delivery.
- Product data support clearer communication for overseas tendering, distributor quotation and technical review. Before quotation:
Please confirm PV capacity, AC voltage, inverter circuit quantity, input and output circuits, metering requirement, enclosure material, installation method and protection degree.
