18kWh 51.2V Floor Standing Lithium Battery with 346Ah and 10kW Output

This 18kWh floor standing lithium battery is the higher-capacity option for projects that require more stored energy than the 15kWh configuration. Its 51.2V, 346Ah LiFePO4 platform is suitable for larger homes, farms, clinics, shops and small commercial energy systems.

The increased capacity is intended to extend the available energy reserve rather than increase inverter output. A compatible external inverter remains necessary for solar charging and AC load supply.

More Energy for Longer Operating Periods

The stated 18,000Wh capacity provides additional energy for projects with higher evening consumption, longer overnight operation or a greater backup reserve for priority equipment.

This model can be considered when the 15kWh battery is close to the calculated daily requirement and the buyer wants additional operating margin. Final capacity should still be selected from actual watt-hour consumption rather than product size alone.

Plan Enough Charging Energy for Daily Recovery

A larger battery requires an appropriately sized solar array, inverter charger or other AC charging source. The charging system should replace the energy used during the available solar or utility charging period.

The battery supports up to 150A of continuous charging and 200A of continuous discharging. These values are maximum limits; actual settings should be selected according to the inverter and required operating strategy.

CAN, RS485 and RS232 communication interfaces support integration with compatible inverter and monitoring equipment. Protocol compatibility should be confirmed before production.

Project Delivery and Long-Term Storage

The battery weighs approximately 163kg. Site access, unloading arrangements, floor strength and the final installation position should be prepared before delivery.

The IP22 enclosure requires a dry indoor or protected technical location. For extended storage periods, the specification requires a maintenance charge at least once every three months.

18kWh Capacity and Deployment FAQ

When should a project choose 18kWh instead of 15kWh?

The 18kWh option is more suitable when the calculated daily energy use approaches the smaller battery capacity or additional reserve is required.

Does the higher capacity increase the maximum AC load?

Not automatically. Maximum AC load is determined by the external inverter and battery-current settings.

How should the charging system be sized?

It should be based on daily battery use, available sunlight, inverter charging power and the time available to restore the energy reserve.

What should be prepared before the battery arrives?

Confirm the unloading route, stable floor location, ventilation, cable access and protection from water or condensation.

Does the battery require attention during long storage?

Yes. The specification requires a maintenance charge at least once every three months during storage.
