LiFePO4: Zero Thermal Runaway Risk
Scalable Design: 5 kWh to 76.8 kWh
The Li-PRO 5120 supports up to 15 units in parallel, scaling total system capacity from 5 kWh to 76.8 kWh. Each unit has its own independent BMS, so expanding an existing installation requires no reconfiguration. Simply mount, wire, and commission the new battery. Start with one unit and add more as your energy needs or budget grows.
Hidden Wiring for Clean, Protected Installation
All wiring connections are routed through the back of the Li-PRO 5120, keeping the front face clean and uncluttered. This design improves the visual appearance of wall-mounted installations and protects cables from UV exposure, physical damage, and accidental contact. This is especially important for outdoor setups where the battery's IP65 enclosure is exposed to the elements.
Wall-Mounted or Floor-Standing Installation
The Li-PRO 5120 supports both wall-mounted and floor-standing installation using the included mounting bracket. Wall mounting saves floor space and positions the battery closer to the inverter, reducing cable runs. Floor standing suits garages, utility rooms, or situations where wall structure cannot support the battery weight. Both methods are compatible with the IP65-rated enclosure for indoor or outdoor use.
5 kWh and 10 kWh Capacity Options
The Li-PRO series offers 5 kWh (Li-PRO 5120) and 10 kWh (Li-PRO 10240) wall-mounted batteries, sharing the same communication protocols, mounting system, and app-based monitoring. Choose the capacity that fits your daily energy consumption, or mix both sizes in a parallel configuration to match your household load precisely.
Compatible with AC-Coupled and DC-Coupled Solar Systems
Whether you are installing a new DC-coupled solar system or adding storage to an existing AC-coupled PV setup, the Li-PRO 5120 integrates with both configurations. It communicates with over 30 hybrid and off-grid inverter brands via CAN bus and RS485 protocols, making it a flexible solution for any residential solar installation, new-build or retrofit.

Why Solar Installers Choose This Battery
Most 5kWh wall-mounted batteries on the market communicate only through RS485 or CAN and are rated for indoor use only. The BSLBATT Li-PRO 5120 goes further on both fronts.
It includes built-in WiFi and Bluetooth connectivity at no added cost, giving installers and homeowners direct access to real-time battery data through the BSLBATT app: state of charge, voltage, current, temperature, and cycle history. No third-party dongles or gateways are needed.
Its IP65 ingress protection rating eliminates the need for a separate weatherproof enclosure when the battery is mounted outdoors near the inverter, reducing cable runs and simplifying installation. The hidden wiring design keeps connections clean and protected from UV exposure and physical damage.
With pre-loaded communication protocols for over 30 inverter brands covering both CAN and RS485, the Li-PRO 5120 integrates into virtually any residential solar system without custom configuration.
Compatible Inverter Brands
The Li-PRO 5120 communicates via CAN bus and RS485 protocols, with pre-loaded firmware for over 30 inverter brands. Default settings: CANBUS set to Victron, RS485 set to Pylon.

Where the 5kWh Home Battery Fits
Solar self-consumption
Store excess daytime solar generation and discharge after sunset. A single 5kWh unit typically covers 6 to 10 hours of essential household loads, reducing grid dependence and maximizing the return on your solar panel investment.
Backup power during outages
Keep critical loads running when the grid goes down, including lighting, Wi-Fi routers, refrigerators, and medical equipment. The battery switches seamlessly between grid-tied and backup modes.
Time-of-use arbitrage
Charge the battery from the grid during off-peak hours and discharge during peak-rate periods to lower electricity bills. This is especially effective in markets with tiered or time-of-use tariffs.
Off-grid solar systems
Pair with solar panels and a compatible hybrid inverter for complete energy independence in remote homes, farms, or cabins. Scale capacity by adding more units in parallel as energy needs grow.
Frequently Asked Questions
Q: Can Li-PRO 5120 be installed outdoors?
Yes. The BSLBATT Li-PRO 5120 carries an IP65 rating, meaning it is fully protected against dust ingress and low-pressure water jets from any direction. It can be wall-mounted outdoors without an additional enclosure.
