A systematic installation checklist prevents costly mistakes and ensures your battery system operates safely and efficiently for 10-15 years. This checklist covers everything from delivery inspection to commissioning.
>Before Delivery
- Confirm battery bank dimensions fit the allocated space
- Verify battery room ventilation meets requirements
- Confirm floor can support weight (flooded batteries are very heavy: 2V 1000Ah cell = ~75kg)
- Order all cables, fuses, bus bars, and monitoring equipment
- Schedule qualified electrician for grid connection
Delivery Inspection
- Check battery voltage of each unit — should be within 0.1V of each other
- Inspect cases for cracks, swelling, or damage
- Verify model numbers match order
- Request quality certificates and test reports
- Document serial numbers for warranty registration
Installation Steps
- Install battery rack. Secure to floor. Check level.
- Place batteries in configured arrangement. Leave gaps for ventilation.
- Connect series strings (use torque wrench to specified torque).
- Connect parallel strings using equal-length cables to bus bars.
- Install DC fuses or breakers on each string.
- Connect battery monitor shunt on negative bus bar.
- Connect temperature probe to center of battery bank.
- Double-check polarity and connection torque.
- Connect to inverter/charge controller.
- Commission charge controller with correct voltage settings.
Commissioning Checks
- Verify float voltage after 24 hours
- Confirm battery monitor is reading correctly
- Test low-voltage disconnect function
- Record baseline readings: voltage, current, temperature
