Maintenance Tips
- Keep batteries within the recommended temperature range; avoid charging below 32°F (0°C) and protect from prolonged extreme heat.
- Use a compatible 24V LiFePO4 charger/inverter with the correct charge voltage setting (28.8V).
- Avoid leaving the battery bank at 0% state of charge for extended periods; recharge promptly after deep discharges.
- For long-term storage, keep batteries at a partial charge and store in a cool, dry location.
- Inspect battery cables, terminals, and connections regularly for tightness, corrosion, or damage.
- Ensure adequate ventilation around the battery bank and keep it free from dust, moisture, and debris.
- Monitor system performance periodically through your inverter or battery monitoring system to identify abnormal voltage or temperature conditions early.
- Do not exceed the battery bank’s rated charge or discharge limits; rely on the built-in Battery Management System (BMS) for protection.
- Keep firmware and inverter settings updated according to manufacturer recommendations when applicable.
