High-efficiency monocrystalline modules are used, with power and quantity configured for the system.

BMS communication management display

BMS communication management

The inverter and lithium battery support BMS communication for charge-discharge control and battery-status management.

Modular storage expansion display

Modular storage expansion

Storage capacity can be expanded according to load and runtime requirements for later system scaling.

APP remote monitoring display

APP remote monitoring

An optional remote monitoring module can display generation, consumption, and storage operating status.

Aluminum PV mounting structure display

Aluminum PV mounting structure

The mounting structure can be customized for roof or ground conditions, with attention to weather resistance, corrosion resistance, installation, and maintenance.

Load Examples

Reference Runtime from the Source Material

For initial selection only.

Individual loadReference runtime
3P air conditioner 2100 Wapproximately 50 hours
Induction cooker 2000 Wapproximately 52 hours
Washing machine 1000 Wapproximately 100 hours
Water pump 800 Wapproximately 130 hours

The runtime figures are single-load reference values from the source material and do not mean that every appliance can run simultaneously for the stated duration. Actual runtime depends on solar irradiation, temperature, system efficiency, battery state of charge, depth of discharge, and load variation.

Before you inquire
