Advantages of LiFePO4 technology in solar batteries
The low-voltage LiFePO4 solar battery uses lithium iron phosphate chemistry, the safest and longest-lasting on the residential storage market:
- Greater safety — doesn’t generate toxic gases or pose a risk of spontaneous combustion
- Over 8,000 lifecycle cycles — over 15 years of daily use
- No memory effect — can be partially charged and discharged with no loss of capacity
- Superior chemical stability compared with other lithium chemistries
- Stable performance across a wide temperature range
- Greater usable depth of discharge (DoD)
Multi-parallel configuration — scale your storage
One of the main advantages of the BXB 16KLV low-voltage LiFePO4 solar battery is its multi-parallel design that allows multiple units to be connected to increase total capacity:
- 1 unit — 16 kWh — standard autonomy for average residential consumption
- 2 units — 32 kWh — extended autonomy for households with higher consumption
- 3+ units — up to several days of autonomy in off-grid installations
- Subsequent expansion without changing the inverter or modifying the installation
Applications of the low-voltage LiFePO4 solar battery
- Residential solar self-consumption — stores surplus for night-time use
- Off-grid installations — full autonomy with no grid connection
- Energy backup — continuous supply during grid outages
- Tariff optimisation — charging at off-peak hours, discharging at peak hours
- Electric vehicle integration — smart management of car charging
CAN and RS485 communication
The BXB 16KLV low-voltage LiFePO4 solar battery features CAN and RS485 communication protocols for seamless integration with compatible hybrid inverters:
- CAN: high-speed communication protocol for real-time management with the inverter
- RS485: standard protocol for integration with monitoring systems and external BMS
- Compatible with Bexie BE Series LV hybrid inverters
- Enables full monitoring from the Bexie Monitoring platform
LV battery vs HV battery — which one do I need?
- LV battery (this one): operates at 51.2 Vdc, more cost-effective, ideal for inverters up to 6-10 kW, easier to handle during installation
- HV battery: operates at a higher voltage, greater efficiency in high-power installations, recommended for 5-30 kW inverters
The BXB 16KLV is the most suitable option for residential installations with LV hybrid inverters from the BE3.6-6KW-1PH (LV) or BE8/10KW-1PH (LV) range.

Frequently asked questions about the low-voltage LiFePO4 solar battery
Which inverter do I need for this low-voltage LiFePO4 solar battery?
The BXB 16KLV requires a low-voltage (LV) hybrid inverter compatible with 51.2V LiFePO4 batteries. It’s compatible with the Bexie BE3.6-6KW-1PH (LV) and BE8/10KW-1PH (LV) hybrid inverters. Contact our technical team to confirm compatibility with your inverter.
How much autonomy does a 16 kWh battery give me?
It depends on the household consumption. For a home with average night-time consumption of 10-12 kWh, a 16 kWh battery covers approximately one full night. For greater autonomy, you can add a second unit in parallel.
How many units can I connect in parallel?
The BXB 16KLV low-voltage LiFePO4 solar battery supports multi-parallel configuration. Refer to the technical datasheet or contact our technical team for the maximum number of units in parallel allowed with your inverter.
How long does this battery last?
LiFePO4 technology guarantees over 8,000 charge and discharge cycles while maintaining more than 80% of nominal capacity, equivalent to over 15 years of daily use under normal conditions.
Can it be installed outdoors?
Refer to the technical datasheet for the operating temperature range and IP rating of this model. For outdoor installation, we recommend protecting the unit from direct solar radiation and extreme temperatures.
