Our wall-mounted 48V LiFePO4 solar battery combines top-tier safety with over 6,000 charge cycles, delivering a stable output of up to 5.12 kW.
Perfect for homes, mobile applications, or commercial projects, it is flexible to expand and compatible with most inverters on the market.
The integrated 100A Battery Management System (BMS) provides real-time monitoring, intelligent cell balancing, and multi-level protection against overcharging, deep discharge, overcurrent, and extreme temperatures.
Designed for demanding energy applications, it optimizes battery performance and extends lifespan — ensuring a consistent, safe, and efficient power supply.
The integrated smart management system continuously monitors voltage, current, temperature, and state of charge (SOC) in real time to ensure stable and safe performance at all times.
An integrated LED display shows all key parameters directly on the device, while Bluetooth and WiFi connectivity allow you to track values conveniently via mobile app on your smartphone or tablet.
With RS485/RS232/CAN communication interfaces, the system can be seamlessly integrated with most inverter brands.
The wall-mounted modular design saves valuable space and allows parallel expansion to meet growing energy demands.
With broad compatibility with off-grid and hybrid solar systems, it’s ideal for home backup power, small businesses, telecom installations, and remote cabins.
Its silent, maintenance-free operation makes it perfectly suited for indoor installation.
Our dedicated team of engineers and inverter specialists is available by phone to answer your questions and make the switch to advanced inverters as simple as possible.

Nominal voltage is 51.2 V, made from 16 cells (3.2 V nominal each).
Full charge (max) is 58.4 V → ~3.65 V per cell.
Discharge cutoff (min) is 40 V → ~2.5 V per cell
Standard charge/discharge: 50 A (≈ 0.25 C).
Max continuous charge/discharge: 100 A (≈ 0.5 C), only at temperatures ≥ 10 °C(51.2V-300Ah is 200A)
BMS will shut off charging/discharging beyond the limits.
Fast charging within the design specs (up to 0.5 C) is acceptable. Going above can stress the battery, reduce cycle life, or trigger BMS protection
Charging: 0 °C to 45 °C; Discharging: –20 °C to 55 °C; Storage: –10 °C to 45 °C (short‑term: –20 °C to 65 °C).
Do not charge below 0 °C (risk of lithium plating). Warm the cells to about 5 °C first if below freezing
Rated at ≥ 6000 cycles at 80% depth of discharge and 25 °C. Typical lithium‑iron‑phosphate cells last 2,500–9,000+ cycles depending on use
BMS performs passive balancing automatically when a cell hits ~3.40 V.
SOC LED indicators show ranges: 0–25%, 25–50%, 50–75%, ≥ 75%.
LCD shows voltage, current, temperature, and balance status.
Series wiring is not recommended unless done by the manufacturer.
To expand capacity or voltage, it’s safer to use fully compatible modules managed by same-series BMS (max 16 units parallel).
Improper series/parallel wiring may cause imbalance, risk, or invalidated warranty
No. Lead‑acid chargers operate at lower voltages (≈ 2.3–2.45 V per cell), which results in undercharging and no proper balance—this shortens life and affects capacity. Use a charger designed for LiFePO4 chemistry (≈ 3.6–3.65 V per cell)
LiFePO4 chemistry offers higher thermal and chemical stability versus other lithium-ion types.
It’s significantly more resistant to thermal runaway; cell thermal runaway occurs at around 220–240 °C, much higher than NMC‐type cells (~160–230 °C)
Still, avoid physical damage, overcharging, and exposure to extreme temperatures.
Don’t leave it charging unattended, and use only manufacturer-approved chargers and equipment.
Keep discharge depth ≤ 80% (avoid full cycles regularly).
Operate and store at moderate temperatures (~25 °C ideal).
Avoid charging below freezing, and don’t overcharge beyond cutoff voltages.
