Product Description

Product Description

 

Working Principle of Off-Grid Solar Power Generation System

1. Photoelectric Conversion
When sunlight irradiates solar panels, based on the photovoltaic effect, semiconductor materials in the panels absorb photon energy, generating electron-hole pairs that form an electric current. This process converts solar energy into direct current (DC).
2. Charging Control
The DC power generated by the solar panels enters a controller, which monitors parameters (such as voltage and current) and adjusts the charging process from the panels to the battery. This ensures safe charging and prevents overcharging.
3. Energy Storage
The battery stores electrical energy through internal chemical reactions, converting it into chemical energy for storage. When sunlight is insufficient, it reverses the process, converting chemical energy back into electrical energy for output.
4. Inversion and Output
An inverter transforms the DC power from the battery into standard alternating current (AC). It also controls the quality of the output by regulating parameters like voltage and frequency to meet grid-standard requirements.
5. Load Power Supply
The AC power generated by the inverter is transmitted to various electrical loads to meet their power demands. The system dynamically balances and stabilizes the power supply according to real-time load requirements, ensuring stable operation.

FAQ

FAQ

1.How should lithium batteries be used in low-temperature environments? It can be discharged at -20ºC to 0ºC, but the charging and discharging efficiency decreases. It is recommended to turn on the battery heating function (optional for some models). Do not use at temperatures below -30 ºC to prevent permanent damage to battery performance.

2.Are lithium batteries environmentally friendly? Does it contain heavy metals? They are made of lithium iron phosphate material, free of heavy metals such as lead and cadmium, the material is recyclable and complies with CE and UN38.3 certifications.

3.What is the warranty period for lithium batteries? Generally, a 5-year or 10-year warranty is provided (with slight variations for different models). Please refer to the product manual for specific details.
