Product Description


Feature

The system utilizes modular inverter units in parallel configuration, where

each inverter module's DC input corresponds to a dedicated battery cabinet,

enabling per-cluster management to eliminate circulating currents between

battery strings.

The AC/DC power modules support flexible deployment in both quantity and

power rating, with a maximum capacity of 60kW modules in a 5-unit parallel

configuration.

The AC output from the power modules is delivered through a transformer

isolated output stage, supplying power to the load with strong resistance to

current shock.

The hybrid ESS employs DC-coupled photovoltaic integration, achieving high

energy conversion efficiency and optimized for off-grid scenarios with PV

generation capacity exceeding load demand; Outdoor-rated MPPT controllers

integrate combiner and MPPT functionalities into a single hardened enclosure.

The complete system includes a diesel generator ATS option, a 300kW hybrid

inverter, PV MPPT controller, and a battery energy storage system.
