Grid-Connected PV Box
For small and medium grid-connected PV projects below 100 kW that need one integrated AC-side box between the inverter and the grid or user side.
What it doesThe grid-connected PV box collects AC output from the inverter, distributes it to the grid or load side, and reserves positions for energy metering and data collection. It integrates isolation, overload, short-circuit, surge grounding, over-voltage, under-voltage and voltage-loss protection.
Why buyers choose it- 10 / 25 / 30 / 50 / 60 kW options cover common rooftop and small commercial PV projects.
- Outdoor IP65 wall-mounted enclosure supports complex site conditions.
- Optional cold-rolled steel, galvanized sheet or stainless steel enclosure helps match budget and environment.
- Ventilation layout helps reduce internal temperature and extend component service life.
- Reclosing and metering configuration supports stable grid-connected operation.
Please confirm PV capacity, AC voltage, inverter output circuits, meter requirements, enclosure material, installation environment and destination country.
