Charging Parameters

To ensure optimal performance and longevity, verify that all charging components (converters, inverter/chargers, solar controllers, DC-DC chargers, etc.) can be programmed to match the following:

• Bulk/Absorption Voltage: 14.2V – 14.6V

• Absorption Time: ~30 minutes per 200Ah in parallel

• Float Voltage: 13.4V – 13.8V

• Equalization: Disabled or set to 14.4V

• Temperature Compensation: Disabled

• Recommended Charge Rate: 50% of battery or bank capacity

• Operating Charge Temp: 32°F to 131°F (0°C to 55°C)

• Operating Discharge Temp: -4°F to 140°F (-20°C to 60°C)

• Cell Charge Temp Range: 32°F to 131°F (0°C to 55°C)

Note: Not all chargers support multistage charging. If yours does not, ensure it can be manually set to the recommended bulk/absorption voltage. Disable float, equalization, and temp compensation if not compatible. Consult your charger's manual or manufacturer for guidance.
