The BWG grid-connection cabinet connects in series between the grid-connected inverter — or an AC combiner box — and the grid in high-power PV plants. It provides grid under- and over-voltage, input surge, system overcurrent and grid- isolation protection, with a multi-function meter behind a sealed anti-tamper window and an integrated design that isolates the distribution and metering sections. Anti-islanding and power-quality monitoring devices can be added.

Overview
The BWG grid-connection cabinet sits between PV inverters (or an AC combiner box) and the grid in high-power photovoltaic plants, providing under/over- voltage, surge, overcurrent and grid-isolation protection with multi-function metering and anti-islanding support.
Key features
- Connects in series between PV inverters / AC combiner box and the grid.
- Grid under/over-voltage, surge, overcurrent and isolation protection.
- Distribution and metering sections isolated to reduce interference.
- PV-specific molded-case reclosing circuit breaker.
- Compatible with anti-islanding and power-quality monitoring devices.
