Technical specifications of the low-voltage residential solar battery PRO
- Type: low-voltage (LV) solar battery PRO version
- Capacity: 5 kWh
- Configuration: expandable multi-parallel
- Version: PRO — high-end range
- Use: residential energy storage
Advantages of the low-voltage residential solar battery PRO version
The BXB 5KLV-PRO low-voltage residential solar battery offers differential advantages over the standard version:
- Premium finish with a more compact and aesthetic design
- Higher energy density per unit of volume
- Additional certifications including UKCA and RoHS
- Multi-parallel configuration for maximum scalability
- Greater compatibility with LV hybrid inverters on the market
- Product video and user manual included for easy installation
Multi-parallel configuration — scale your storage
One of the main advantages of the BXB 5KLV-PRO low-voltage residential solar battery is its multi-parallel design:
- 2 units — 10 kWh — standard overnight autonomy
- 3 units — 15 kWh — extended autonomy or installations with higher consumption
- 4+ units — capacity for off-grid or maximum autonomy
- Subsequent expansion without changing the inverter or modifying the installation
Applications of the low-voltage residential solar battery
- Residential solar self-consumption — stores surplus for night-time use
- Off-grid installations — full autonomy with no grid connection
- Energy backup during grid outages
- Tariff optimisation — charging at off-peak hours, discharging at peak hours
- Integration with electric vehicle for smart charging management
- Premium installations where design and finish matter
BXB 5KLV-PRO vs BXB 16KLV — which one to choose?
- BXB 5KLV-PRO (this one): 5 kWh per unit, high-end PRO version, more units in parallel for greater flexibility, premium design
- BXB 16KLV: 16 kWh per unit, greater capacity in fewer units, more cost-effective option per kWh stored
The BXB 5KLV-PRO is ideal when you want to start with a small capacity and expand progressively. The BXB 16KLV is a better choice when the total capacity needed is known from the start.
Certifications and regulatory compliance
- IEC 61000 — electromagnetic compatibility
- IEC 62619 — safety of lithium battery storage systems
- UKCA — conformity marking for the UK market
- RoHS — restriction of hazardous substances in electrical equipment

Frequently asked questions about the low-voltage residential solar battery PRO
Which inverter do I need for the BXB 5KLV-PRO low-voltage residential solar battery?
The BXB 5KLV-PRO requires a compatible low-voltage (LV) hybrid inverter. 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 specific inverter.
How many units can I connect in parallel?
The BXB 5KLV-PRO low-voltage residential solar battery supports multi-parallel configuration. Refer to the technical datasheet or contact our team for the maximum number of units in parallel allowed with your inverter.
How much autonomy does a 5 kWh unit give me?
For a household with night-time consumption of 5-6 kWh, one unit covers approximately one night. For greater autonomy, add more units in parallel. As a reference, the average night-time electricity consumption in European homes is 5-8 kWh.
What’s the difference between the PRO version and the standard version?
The PRO version offers higher energy density, premium finish, additional certifications (UKCA, RoHS) and greater compatibility with inverters on the market. It’s the recommended option for installations where quality and design are a priority.
How long does this battery last?
LFP (lithium iron phosphate) technology guarantees over 6,000 charge and discharge cycles while maintaining more than 80% of nominal capacity, equivalent to over 15 years of daily use under normal conditions.
