Solution Overview

This product features comprehensive safety protections including overcharge, overload, and short‑circuit protection, with manual AC/DC disconnection and one‑key emergency stop. It adopts high‑efficiency three‑level technology, reaching up to 98.7% operating efficiency and 99.9% MPPT accuracy, and supports 110% continuous overload operation.

Compatible with three‑phase three‑wire / four‑wire systems, it provides power factor control, active/reactive power compensation, and harmonic and three‑phase imbalance suppression. Its control system uses redundant AC/DC dual power supplies, integrating switches, pre‑charging circuits, and an independent BMS power and communication supply.

It supports flexible capacity expansion via multi‑module parallel connection, with LVRT/HVRT and strong grid adaptability, and a designed service life of over 25 years. With an optional DC/DC converter, PV power can directly supply loads or charge batteries via a bidirectional AC/DC converter.

The EMS manages battery charging and discharging through the bidirectional converter. After DC‑to‑AC inversion, power is distributed via an STS static transfer switch, connecting to the grid or supplying local loads directly. The EMS monitors system status in real time, intelligently schedules PV and energy storage, prioritizes on‑site PV consumption, stores or feeds surplus power to the grid, supplements power from batteries when needed, and switches to off‑grid mode during grid outages to ensure uninterrupted power supply and stable source‑grid‑load‑storage coordination.
