🔋Choose the right battery
Choosing the right battery is very important for your inverter to work safely and stably.
1. Selection Principle
The actual output power of the inverter is determined by the discharge capability of the battery.
If the battery capacity is too small, the following problems will occur:
⭐Low voltage alarm
⭐Automatic shutdown
⭐Unable to drive loads
⭐Cannot reach rated power
2. How to calculate the required battery current
The maximum current the battery needs to supply depends on your inverter power and battery voltage.
Formula:
Discharge Current (A) = Inverter Rated Power (W) ÷ Battery Voltage (V) ÷ 0.85
3. Suggested Battery for Common Inverters
For 12V Batteries
⭐500W inverter → Recommended battery: 70Ah or above
⭐1000W inverter → Recommended battery: 100Ah or above
⭐1500W inverter → Recommended battery: 150Ah or above
⭐2000W inverter → Recommended battery: 200Ah or above
For 24V Batteries
⭐1000W inverter → Recommended battery: 70Ah or above
⭐1500W inverter → Recommended battery: 100Ah or above
⭐2000W inverter → Recommended battery: 150Ah or above
⭐3000W inverter → Recommended battery: 200Ah or above
4. Important Tips
⭐Insufficient battery capacity will cause low voltage alarm, shutdown or unable to reach full power.
⭐For long life and safe use, do not overload the battery.
⭐If you need help choosing a battery, please tell us your inverter model and load power.
