Off-Grid & Home Storage LiFePO4 Batteries

Q: 3. 12 V, 24 V or 48 V – which system voltage is sensible for my project?

For small backup solutions and garden sheds, 12 V is usually sufficient. For larger off‑grid systems with an inverter (house, cabin, home office), 24 V is more efficient because the currents are lower. For almost self‑sufficient single‑family homes, many inverters operate with 48 V systems – our 12‑ or 24‑V batteries are integrated here via suitable equipment (e.g. inverter / DC converters).

Q: 4. How do I combine multiple batteries correctly – in parallel or in series?

More capacity at the same voltage is achieved by parallel connection (e.g. 2× 12V 280Ah in parallel). A series connection to increase voltage is only permitted if it is expressly authorized in the datasheet – otherwise do not try it. Always combine only identical Lithink models and coordinate the design and protection with your electrician.

How Do You Choose Your Battery

Off-Grid & home storage?

8 reasons why Lithink is the ideal foundation for home electricity, PV storage, and backup power.

More usable energy from your PV system

Lithink LiFePO₄ batteries can be deeply discharged and make a large portion of their rated capacity truly usable – ideal for using solar power generated during the day into the night, instead of giving energy away to the grid.

World's No. 1 LiFePO₄ Internal Build Quality

First-class internal construction quality: reinforced support frame, epoxy insulation all around, and protected wiring. The result: greater structural stability, improved vibration resistance, and a longer cell lifespan.

Safe through the winter – with self-heating

Models with a heating function automatically warm the battery while charging when it’s cold outside, protecting it from critically low temperatures. That way your storage remains ready for use even in an unheated garage, in the utility room or in the mountain cabin.

Perfect for PV, backup power & fast charging

Lithink batteries are designed for frequent charge/discharge cycles and tolerate daily PV cycles as well as occasional fast charging via suitable chargers or hybrid inverters – ideal for self-consumption optimization and backup power.

Everything in View with Bluetooth App

With the Lithink App you can see the state of charge, voltage, current and temperature of your battery storage in real time – including warnings before important loads such as your router, heating or cooling become critical.

Modular system – storage grows with you

Whether a small off-grid cabin or a larger single-family home: multiple Lithink batteries can be combined into a larger storage system and integrated into compatible 12-/24-/48-V systems. This allows your capacity to grow with your energy needs.

Safety BMS with 30+ protection functions

An automotive-grade BMS continuously monitors each battery with over 30 measurement and protection parameters – including over-/under-voltage, overcurrent, short circuit, and over- and under-temperature. Multiple temperature sensors ensure that your storage remains safe and stable even under high load, during intensive PV cycles, and in winter operation.

Long lifespan & 10-year warranty

A+ cells, rigorous Lithink lab tests and thousands of life cycles make your storage an investment for years to come. It's rounded off by our long-term 10-year warranty.

LiFePO4 batteries for Off-Grid & Home Storage

Gain greater independence from the power grid with Lithink LiFePO4 batteries for home, holiday home, and off-grid cabins. Our storage systems efficiently absorb solar power, provide a stable, quiet energy supply for essential loads, and also serve as a reliable backup power source during grid outages. Thanks to high cycle durability, an integrated safety BMS, and optional self-heating, they are ideal for 12-, 24- and 48-V systems – from PV self-consumption installations to fully autonomous off-grid setups.

Any Questions About Off-Grid & Home Storage?

Read our frequently asked questions — and if you're still unsure afterwards, just write to us directly.

1. How do I find the right Lithink battery for my off-grid or home storage system?

First determine which scenario applies to you: garden shed, weekend cabin, holiday home, or partially off-grid single-family home. Then compare your consumption with our tables on this page (kWh per day / typical appliances). There you can immediately see which Lithink configuration (e.g. 1× 24V 100Ah or 2× 12V 280Ah in parallel) we recommend for your scenario.

2. How much storage capacity (kWh) do I need per day?

Write down your main appliances, their power (Watt) and daily operating hours. Calculate: Watt × hours = Wh, the total equals your daily consumption in Wh or kWh. Example: 150 W refrigerator × 10 h ≈ 1.5 kWh. Compare the value with our ranges (e.g. 2–4 kWh / 4–8 kWh) to choose the appropriate battery size.

3. 12 V, 24 V or 48 V – which system voltage is sensible for my project?

For small backup solutions and garden sheds, 12 V is usually sufficient. For larger off‑grid systems with an inverter (house, cabin, home office), 24 V is more efficient because the currents are lower. For almost self‑sufficient single‑family homes, many inverters operate with 48 V systems – our 12‑ or 24‑V batteries are integrated here via suitable equipment (e.g. inverter / DC converters).

4. How do I combine multiple batteries correctly – in parallel or in series?

More capacity at the same voltage is achieved by parallel connection (e.g. 2× 12V 280Ah in parallel). A series connection to increase voltage is only permitted if it is expressly authorized in the datasheet – otherwise do not try it. Always combine only identical Lithink models and coordinate the design and protection with your electrician.

5. What do I need to consider for the PV system, inverter, and temperatures?

The PV output should match your daily consumption — use the PV guideline values in our tables as a reference. Inverters, MPPT controllers and chargers must be suitable for LiFePO₄ and match the battery’s voltage & current. In cold conditions: only charge below 0 °C with suitable Lithink models (e.g., those with self-heating); the BMS additionally protects the battery from harmful temperatures. If you’re unsure, simply send us your device sizes and we will check the combination for you.
