Core Components
System Components and Functions
Every product group presents the following configuration areas.
BMS communication management
The inverter and lithium battery support BMS communication for charge-discharge control and battery-status management.
Modular storage expansion
Storage capacity can be expanded according to load and runtime requirements for later system scaling.
APP remote monitoring
An optional remote monitoring module can display generation, consumption, and storage operating status.
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 load | Reference runtime |
|---|---|
| 1P air conditioner 750 W | approximately 10 hours |
| Induction cooker 2000 W | approximately 6 hours |
| Washing machine 1000 W | approximately 11 hours |
| Water pump 800 W | approximately 12 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.
