1. Product Positioning & Application Scenarios
This power frequency charger-inverter all-in-one unit delivers pure sine wave output and is primarily designed for off-grid power supply scenarios including vehicle-mounted and communication power systems. Featuring powerful load-carrying capacity, it can drive a wide range of loads such as household appliances, office equipment, electric tools and industrial lighting. It is also compatible with inductive loads that produce high startup surge power, including motors and refrigerators.
2. Integrated Core Functions
The equipment integrates inverter and charging modules to output pure sine wave voltage.It is equipped with a UPS uninterruptible power supply function. When mains power fails, the unit rapidly switches to battery inverter power supply to avoid shutdown of electrical appliances caused by power loss.
Embedded with an intelligent charging program, it is compatible with lithium batteries, lead-acid batteries, gel batteries and flooded lead-acid batteries. Severely depleted batteries will start charging and recover automatically once connected to mains electricity.
3. Control and Communication Configuration
The device supports CAN communication and reserves multiple communication ports on the body. A dedicated remote control panel is available as an optional accessory, which allows remote power on/off operation and real-time viewing of operating data such as voltage and battery capacity, realizing intelligent monitoring of the entire power supply system.
Fitted with cooling fans and three-color status indicator lights, the unit visually identifies working states including mains power supply, battery inversion, charging, fully charged and fault alarms.
4. Safety Protection & Fault Handling
Multiple protection circuits are built into the unit. When abnormalities such as overload, overheating, undervoltage or hardware faults occur, the fault light flashes accompanied by a buzzer reminder.
A complete troubleshooting guide is attached to the manual for quick diagnosis of common issues including no device response, charging failure and abnormal output.
