Set your preferred battery charge/discharge limits through the inverter’s menu.

Step 3: Core Functions and Daily Use

The system operates automatically in off-grid mode. When solar power is available, it charges the battery first, then powers loads. If the battery is full and solar is still producing, excess power is wasted unless you have a grid connection. The inverter switches between battery and solar sources seamlessly — in our review, we saw zero transfer time during grid simulations.

Step 4: Advanced Techniques

For maximizing self-consumption, program the inverter to prioritize solar during peak sunlight hours and use battery power during evening peaks. If you install multiple batteries, parallel them using the included communication cables to ensure balanced charging and discharging. Our review confirmed that the system handles parallel configurations without issues, balancing currents automatically.

Step 5: Maintenance and Care

Keep the battery and inverter clean and free from dust. Check all connections monthly for tightness. The BMS will alert you via the app if any parameters go out of range. Every six months, run a full charge/discharge cycle to calibrate the battery’s state of charge reading. In our review, this calibration improved accuracy from +/-5% to +/-1%.

Step 6: Troubleshooting Common Issues

If the system doesn’t power on, check the battery breaker and inverter fuse. If solar charging seems low, verify your panel orientation and check for shading. The inverter’s error codes are explained in the manual — in our review, error code 03 meant a communication fault, fixed by reseating the RJ45 cable.
