Integrated 10kW Off-Grid Power System
This 10kW energy storage controller inverter integrated machine combines a pure sine wave inverter, MPPT solar controller and utility charger. It is designed for locations where grid power is unavailable, insufficient or unstable, with utility or generator input available as a backup charging source.
20.48kWh Modular Battery Storage
The confirmed configuration uses four 5.12kWh battery modules for 20.48kWh of total nominal storage. Each module is rated at 51.2V and supports RS485, RS232 and CAN communication. The battery specification lists 90% depth of discharge and 6,000 cycles at 80% DOD and 25°C.
10kW Pure Sine Wave Output
The system provides 10,000W rated output, 230Vac ±5% voltage regulation and selectable 50Hz or 60Hz output. Peak inverter efficiency is 93%, surge capacity is twice rated power for five seconds, and no-load consumption is below 75W.
High-Voltage MPPT Solar Input
The 10kW model supports 10,000W rated PV power, a 90–450Vdc MPPT range and up to 500Vdc maximum PV open-circuit voltage. Maximum PV input current is listed as 27A × 2, with 40A maximum.
Backup Charging and Parallel Expansion
Utility charging current is 150A. The system supports selectable utility, solar or solar-battery priority modes and allows up to six inverter units in parallel with CAN communication.
Applications and Installation
Suitable applications include residential backup power, farms, workshops and small commercial loads where off-grid generation and battery storage are required. PV array sizing, load assessment, protection, earthing and battery communication must be completed by qualified electrical or solar professionals according to the product manual and local regulations.
