2. Safety Information
Please read and understand all safety instructions before installation and operation. Failure to follow these instructions may result in electric shock, fire, serious injury, or death.
- Indoor Use Only: This product is designed for indoor use. It is forbidden to use it outdoors.
- Qualified Personnel: All installation and wiring must be performed by qualified personnel in compliance with local electrical codes and regulations.
- Battery System: This inverter is designed to work ONLY with a 48V battery system. Ensure the battery system is correctly configured before connecting.
- Required Battery: The inverter MUST have a battery connected to function correctly.
- Load Compatibility: Different types of loads have different starting impulse currents. Select the appropriate inverter model based on actual equipment power, current, and load characteristics. For resistive loads, choose an inverter with continuous power higher than the appliance's rated power (ideally 80% of rated power). For inductive loads (motors, compressors), choose an inverter whose continuous power is 3-10 times higher than your appliances.
- Protection Features: The inverter includes built-in protections against battery low/high voltage, over-temperature, overload, and short circuit.
3. Setup and Installation
Mounting the Inverter:
- Choose a dry, temperature-appropriate, and well-ventilated room for installation.
- Ensure proper clearance around the inverter for air circulation and heat dissipation. Leave a gap of about 20cm on both sides and 50cm at the top and bottom.
- Fix the equipment to the wall using recommended M5 screws.
Wiring Connections:
Before starting any wiring, ensure all power sources (solar, battery, AC input) are disconnected and secured. Prepare cables and circuit breakers that meet the specifications provided in the manual. The cable AWG and circuit breaker specifications are determined by the maximum current the cable needs to bear.
- Battery Wiring: Connect the 48V battery bank to the designated BAT+ and BAT- terminals. Ensure correct polarity.
- PV Input Wiring: Connect the solar panel array to the PV+ and PV- terminals. Ensure the PV input voltage (Voc) and current are within the inverter's specifications (Max PV Input Voc: 60-500V).
- AC Input Wiring: Connect the AC utility power or generator to the AC IN terminals.
- AC Output Wiring: Connect your AC loads to the AC OUT terminals.
- Grounding: Properly ground the inverter using the grounding port on the unit. Keep the grounding point as close as possible to the inverter for maximum effectiveness.

The inverter features an LCD display and function keys for monitoring and configuring various parameters. Long press the ENTER button for 3 seconds to enter the setup mode. Use the UP/DOWN buttons to navigate and ENTER to confirm selections.
Work Modes:
- PV Load Priority Mode: Solar energy powers the load first.
- Inverter Priority Mode: Inverter output is prioritized.
- PV Priority Mode: Solar energy is prioritized for charging.
Charging Modes:
- Only Solar Charging: Solar is the sole charging source.
- Mains Priority Charging: Utility power charges the battery preferentially.
- Solar Priority Charging: Solar energy charges the battery as the first priority.
- Mains & Solar Hybrid Charging: Solar energy charges preferentially, with utility power supplementing if solar is insufficient.
Communication Ports:
- RS485/WIFI: For communication with monitoring hosts, lithium BMS, or mobile apps via optional modules.
- USB: Connects to PC software for configuration (requires CH340T driver).
