First, position the battery in your chosen location using the built-in wheels. It is heavy, so definitely use the wheels. You can either place it on a level floor or use the included brackets to wall-mount it. Ensure the area is dry and well-ventilated. Connect the positive and negative terminals to your inverter using appropriately sized cables (at least 2/0 AWG recommended for 200A continuous draw). Tighten all connections securely.

Step 2: First-Time User Guide

After installation, turn on the battery using the main switch on the front panel. The color LCD screen will light up, showing the state of charge (SOC), voltage, and current. For first-time use, or if the battery has been stored for a while, you may need to perform a full charge cycle. Connect your solar charge controller or AC charger and allow the battery to reach 100% SOC. This initial calibration helps the BMS accurately track capacity.

Step 3: Core Functions and Daily Use

In daily operation, the battery works automatically. You can monitor its status via the LCD touch screen. Tap the screen to cycle through different screens showing individual cell voltages, total pack voltage, current flow, and temperature. The CAN/RS485 communication means your inverter can automatically adjust charging parameters based on the battery’s state. For best results, configure your inverter (like a Growatt or Victron) to communicate with this battery using the appropriate protocol.

Step 4: Advanced Techniques

If you are scaling your system, you can connect up to 15 batteries in parallel. Use the included communication cables to link the battery modules together. The master battery will then display the combined status of all connected units. You can also adjust certain battery parameters directly from the LCD screen, such as low-voltage cutoff and charging voltage limits, which gives advanced users fine-grained control over their energy storage.

Step 5: Maintenance and Care

LiFePO4 batteries require minimal maintenance. Keep the terminals clean and tight. Periodically check the LCD screen for any alarm codes or abnormal cell voltages. If storing the battery for a long period, charge it to about 50% SOC and store it in a cool, dry place.
