Working Principle of Off-Grid Solar Power Generation System
|
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). |
|
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. |
|
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. |
|
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. |
|
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
| What safety protection functions do lithium batteries have? | What should be noted during daily maintenance? | How to troubleshoot when a fault occurs? |
| Hardware protection: Over-temperature protection, short-circuit protection, over-current protection, and reverse battery connection protection. Software protection: BMS (Battery Management System) monitors voltage, current, and temperature in real time. It automatically alarms and cuts off the circuit when abnormalities occur. Fire protection measures: Some energy storage systems (such as container-type) are equipped with aerosol or perfluorohexane fire extinguishing systems. |
Regular inspection: Check the LCD display and confirm the battery status (voltage, capacity, temperature). Check if the connection lines are loose and if the interfaces are overheating to avoid poor contact. Cleaning and maintenance: Wipe the outer shell with a dry cloth to prevent dust accumulation that may affect heat dissipation (for forced air-cooled models, ensure that the fan is not blocked). Long-term idle: Charge once every 3 months and keep the battery level between 30% and 50% to avoid deep discharge. |
Common fault handling: 1.Over-temperature alarm: Check if the cooling fan is working properly and if the ambient temperature is too high. Reduce the load or improve ventilation as necessary. 2.Abnormal charging and discharging: Check if the BMS communication is interrupted and if the battery connection lines are loose. Contact after-sales service for battery cell inspection if necessary. |
