HBBWG PV Grid-Connection Cabinet
LV grid-tie cabinet for 400 V distributed PV: anti-islanding protection, auto reclosing on voltage recovery, sealed metering bay and smart telecom — built on MNS/GCS/GCK/GGD frames to suit the site.
- Protection: passive islanding detection, live-line auto closing, over/under-voltage, over/under-frequency and
- Auto grid connection: trips on grid voltage loss and auto-recloses when voltage recovers; smart telecom links
- Energy metering: optional lead-sealed metering bay against power theft, housing utility metering and load-cont
A cleaner, more reliable approach to MV switching
The HP-ELS series replaces SF₆ with environmentally friendly insulating media while keeping the proven safety and performance utilities expect from gas-insulated switchgear.
Product Overview
The HBBWG low-voltage PV grid-connected cabinet serves distributed PV projects in AC 400 V low-voltage systems. It mainly consists of an anti-islanding protection device (with optional fault-decoupling and online power-quality monitoring), an isolating disconnector, a grid-connected circuit breaker, a surge arrester, a temperature/humidity controller, an energy-metering device and the cabinet body. The cabinet type and dimensions are customized to site conditions as MNS, GCS, GCK or GGD.
