10.24kWh 51.2V 200Ah LiFePO4 Battery for Solar Inverters with CAN/RS485 Communication
10.24kWh 51.2V 200Ah LiFePO4 Battery for Solar Inverters
The Voltertech BAT-10KWH-51.2V-W provides 10.24kWh nominal energy from a 51.2V 200Ah LiFePO4 battery platform. Designed for compatible low-voltage solar inverter systems, it supports CAN and RS485 communication, 200A recommended charging and parallel expansion for larger battery banks.
51.2V 200Ah Battery for Solar Inverter Systems
Selecting a solar battery requires more than matching the nominal voltage. The inverter charging range, battery current capability, load power and communication protocol should all be checked before installation.
The BAT-10KWH-51.2V-W uses a 51.2V LiFePO4 platform for compatible low-voltage inverter systems and provides 10.24kWh nominal energy from one 200Ah battery.

Matching Battery Power with the Solar Inverter
The specification lists a recommended maximum load power of up to 8kW and an ultimate maximum load power of up to 10kW. This provides an important reference when matching the battery with a low-voltage solar inverter.
However, inverter kW rating alone is not enough to confirm compatibility. Battery-side DC current, startup loads, inverter settings and BMS limits should also be checked.
- Confirm the inverter brand and exact model
- Check the supported battery voltage range
- Review battery-side charge and discharge current
- Confirm maximum connected load requirements
- Check CAN or RS485 protocol compatibility
200A Charging and 57.6V Charge Reference
The supplied technical specification lists a recommended charge current of 200A and a recommended charge voltage of 57.6V. The BMS charge cut-off voltage is specified at 58.4V.
The connected inverter or battery charger should be configured according to the approved battery charging parameters rather than using a generic lithium charging profile without confirmation.
CAN / RS485 Inverter Communication
The battery provides CAN and RS485 interfaces for communication with compatible solar inverter systems. Communication can allow supported battery operating data and control information to be exchanged between the inverter and BMS.
A CAN or RS485 port alone does not guarantee compatibility. Protocol, cable definition, firmware and inverter settings can differ between brands and models, so the exact inverter model should be confirmed before ordering.
Parallel Expansion for Larger Battery Banks
Up to 15 compatible battery units can be connected in parallel according to the product specification. This provides a flexible path for projects that may need more stored energy later.
10.24kWh nominal energy.
20.48kWh nominal energy.
51.2kWh nominal energy.
153.6kWh nominal energy.
Final battery quantity should also be checked against inverter current limits, communication requirements, DC protection and cable design.
Frequently Asked Questions
1. Can a 51.2V 200Ah battery work with a 48V solar inverter?
It can work with many compatible 48V-class lithium battery inverters, but nominal voltage alone does not confirm compatibility. The inverter voltage window, charging parameters, battery current requirements and communication protocol should be checked first.
2. Is this battery suitable for an 8kW solar inverter?
The product specification lists recommended maximum load power of up to 8kW. Final matching should also consider battery-side DC current, inverter efficiency, startup loads and BMS operating limits.
3. Can it be used with a 10kW inverter?
The specification lists an ultimate maximum load power of up to 10kW, but this should not automatically be treated as a recommended continuous operating condition. The exact inverter model, DC current demand and load profile should be reviewed before configuration.
4. What charging voltage should be used for this 51.2V LiFePO4 battery?
The recommended charge voltage is 57.6V, while the BMS charge cut-off voltage is specified at 58.4V. Charger or inverter settings should follow the approved battery configuration.
5. Does CAN or RS485 guarantee inverter compatibility?
No. The physical communication interface is only one part of compatibility. The communication protocol, firmware, cable pin definition and inverter settings must also match.
6. How many 10.24kWh batteries can be connected together?
The specification supports up to 15 compatible batteries in parallel, providing up to 153.6kWh of nominal battery capacity. Final system design should also consider the inverter, current limits and protection equipment.
7. What information should I provide before ordering?
Provide the inverter brand and exact model, inverter power, required battery capacity, maximum load and planned battery quantity. This allows voltage, current and communication compatibility to be checked before system configuration.
