Deye RW-F10.2 – 10.2 kWh Low-Voltage (LV) LiFePO₄ Battery

The Deye RW-F10.2 is a 10.2 kWh capacity, low-voltage (51.2 V) energy storage battery designed for residential and small commercial systems. The module is based on LiFePO₄ technology, offering safe operation, long service life, and stable performance for solar power systems .

What is it used for?

This battery is primarily intended for systems where the goal is to use the generated energy on-site and increase energy independence.

Typical applications:

• energy storage for residential solar power systems
• increasing self-consumption
• backup operation in the event of a power outage
• small commercial systems

How does it work?

The RW-F10.2 stores energy generated during the day but not used, and later—typically in the evening or during a power outage—feeds it back into the system.

The built-in intelligent BMS continuously monitors the condition of the cells (voltage, temperature, current) and ensures safe operation. It also balances the cells, resulting in a longer service life.

The system is capable of even higher performance: it supports higher discharge currents for short periods, allowing it to handle sudden consumption peaks effectively.

Technical and system-level benefits

Approximately 9.2 kWh of the 10.2 kWh nominal capacity is usable, which is sufficient to cover a significant portion of a single-family home’s daily energy needs.

One of its greatest advantages is modularity: up to 32 units can be connected in parallel, allowing the system to scale up to over 300 kWh. This means it can be used not only in residential applications but also in smaller C&I projects.

The device features IP65 protection, allowing it to be installed indoors and, under suitable conditions, outdoors as well. The wide operating temperature range (-20°C – +55°C) also enables flexible installation.

SOLARKIT Reviews

The RW-F10.2 is a typical, highly usable LV battery that provides a stable foundation for residential energy storage. Thanks to LiFePO₄ technology, it is safe and reliable in the long term.

Its particular strength lies in its scalability: it is not a “fixed” system, but one that is easily scalable. This makes it a good choice for those who wish to expand capacity later on.

Overall, this is a practical, easily integrated battery that is an ideal choice for solar power systems if the goal is to increase self-consumption and achieve energy independence.
