Operation Guide
Ensure correct system installation to maintain the longevity of both the inverter and the connected battery bank.
| Consideration | Recommendation |
|---|---|
| Input Source | Ensure the DC input (12V or 24V) exactly matches your battery system. |
| Load Sizing | Calculate the peak power (surge) of your loads, not just the continuous rating, to prevent overload shutdowns. |
| Cable Sizing | Use high-gauge cables to minimize voltage drop between the battery and the inverter, especially at high loads. |
Safety Note: Ensure proper ventilation around the inverter's cooling vents. Never block the airflow path, as this will trigger the over-temperature protection circuit.
