LiFePO4 battery storage systems for remote homes, cabins, farms and other locations without dependable grid power.
Available configurations include 12V, 24V, 48V and 51.2V batteries for daily cycling, solar energy storage and backup power. We support solar installers, distributors and system integrators with battery sizing, Smart BMS configuration, inverter communication, testing and OEM production.
An off-grid solar battery stores energy generated during the day and supplies connected loads when solar production is low or unavailable.
A dependable system must provide sufficient usable energy without exceeding the current limits of the battery, Smart BMS, inverter, cables or protection equipment.
LiFePO4 battery storage is suitable for applications requiring:
Battery capacity should be calculated from daily energy consumption, required backup time, usable battery capacity and expected system losses.
For loads measured on the AC side, a practical starting formula is:
Required Battery Energy (Wh) = Daily Energy Use (Wh) × Backup Days ÷ Usable Battery Percentage ÷ Inverter Efficiency
For example, a site using 5,000Wh per day, with 80% usable battery capacity and 90% inverter efficiency, requires:
5,000Wh ÷ 0.80 ÷ 0.90 = 6,944Wh
The calculated requirement is approximately 6.94kWh, so a 7kWh or larger LiFePO4 battery system would be needed for one day of backup.
Additional reserve may be required for low temperatures, battery aging, changing energy consumption and periods of limited solar generation. If energy use has already been measured on the battery’s DC side, inverter efficiency should not be deducted again.

An off-grid solar system requires correct integration between the LiFePO4 battery, inverter, charge controller, cables and electrical protection equipment.
Our integration review can cover:
The Smart BMS monitors individual cells and controls battery operation when voltage, current or temperature moves outside the approved range.
Selected battery configurations support CAN or RS485 communication with compatible solar inverters. This allows the inverter to receive battery status and apply suitable charge and discharge limits.
The inverter model, firmware version, BMS protocol and communication cable must be confirmed before sample development or production.
LiFePO4 battery storage can supply lighting, refrigeration, water pumps, communication equipment and household appliances where utility power is unavailable or unreliable.
Off-grid solar batteries can support irrigation controls, monitoring equipment, lighting, feeding systems and other electrical loads in agricultural and rural locations.
Battery systems can be configured for telecom equipment, monitoring stations and remote infrastructure requiring dependable power with limited onsite maintenance.
Project-specific battery capacity, Smart BMS settings and inverter communication can be configured for solar installers and system integrators developing independent power systems.
The correct battery voltage depends on the inverter, system power and installation design. Smaller standalone systems may use 12V or 24V batteries, while home and higher-power off-grid systems commonly use 48V or 51.2V configurations.
Wall-mounted, floor-standing and rack-mounted enclosures are available according to the required capacity, installation environment and service-access requirements.
Off-grid projects differ in electrical load, installation space, charging conditions and communication requirements. For qualified OEM projects, the battery can be configured around the application rather than limited to a standard design.
Customization options include:
To define a suitable configuration, provide the daily energy consumption, inverter model, system voltage, maximum charging current, required backup time and available installation space.
Battery packs are assembled and tested against the approved project specification before shipment.
Production and quality-control procedures can include:

LiFePO4 batteries are widely used for off-grid solar storage because they provide high usable capacity, deep-cycle performance and long service life. The correct configuration depends on daily energy consumption, inverter load, system voltage, temperature and required backup time.
Calculate daily energy consumption in watt-hours and multiply it by the required number of backup days. Divide the result by the usable battery percentage and inverter efficiency. The inverter’s continuous load and startup current must also be checked.
Selected battery systems support CAN or RS485 communication with compatible inverters. Compatibility depends on the inverter model, firmware, BMS protocol and communication cable.
Yes. Both 48V and 51.2V LiFePO4 battery configurations are available. Capacity, enclosure, Smart BMS and communication can be configured for qualified projects.
Selected systems support parallel expansion. The maximum number of batteries, cable configuration and communication arrangement should be confirmed before installation.
Yes. OEM options include custom voltage and capacity, Smart BMS settings, inverter communication, enclosure design, product labels, packaging, sample testing and volume production.
Send us the system voltage, daily energy consumption, inverter model, required storage capacity, peak load, backup time, installation dimensions and estimated order quantity.
Our engineering team will review the information and recommend a suitable LiFePO4 battery configuration for sample development or volume production.
