10.24 kWh Low-Voltage Wall Battery (51.2 V, 200 Ah, IP65)
The Deye RW-F10.2 is a 10.24 kWh, 51.2 V LiFePO₄ wall-mounted battery designed to store a serious chunk of your solar power for use at night, on cloudy days and during blackouts. It’s IP65 weather-rated, uses safe LFP chemistry, can be expanded up to 32 units (around 326 kWh) and comes with a 10-year warranty on the EU/AU version.
BSC Renewables can build this battery into a full solar-plus-storage system that’s sized around your actual power bills and how you use your home or business.
What Is the RW-F10.2?
The RW-F10.2 is a home and small-business battery pack that:
- Stores roughly 10.2–10.24 kWh of energy per unit (51.2 V, 200 Ah) Deye+2Uniz Solar+2
- Uses Lithium Iron Phosphate (LiFePO₄ / LFP) cells
- Is low voltage, which is well-suited to residential systems
- Bolts neatly to a wall or sits on a floor stand, with an IP65 enclosure for harsh environments Deye+2Alibaba+2
In short: it’s a chunky, outdoor-rated battery that lets you hang onto far more of the solar you generate.
Why This Battery Works Well for Aussie Homes and Businesses
1. Turn More of Your Solar Into Real Savings
Without a battery, a lot of your midday solar gets exported to the grid for a small credit. The RW-F10.2 lets you hold onto those kilowatt-hours and use them when you actually need them.
The battery is designed specifically for residential ESS (energy storage) and is part of their low-voltage series for homes and small businesses.
What that means in practice:
- Store surplus solar instead of giving it away
- Use that stored energy in the evening, overnight or on poor-sun days
- Over time, that can cut your grid usage and smooth out power bills
BSC Renewables can look at your actual bills and recommend how many RW-F10.2 units make sense, rather than just throwing a random number at it.
2. Backup Power When the Grid Drops Out
With a compatible hybrid inverter and backup design, the RW-F10.2 is designed for high power, long life and stable operation with support for up to 1C charge and 1.2C discharge, and around 6000 cycles at 90–100% depth of discharge.
That lends itself nicely to backup duties, such as:
- Keeping lights, modem/routers, fridge/freezer and other essentials running during outages
- Avoiding the hassle and noise of a generator for short blackouts
- Letting you ride through grid issues with a lot less stress
BSC Renewables can create a dedicated backup/essential loads circuit so your battery focuses on the things that matter when the power goes out.
3. Wall-Mounted, Weather-Rated and Space-Saving
This model features IP65 protection and a flat design for wall or floor mounting, with natural cooling (no noisy fans) and a wide –20 °C to 55 °C operating range.
Day-to-day benefits:
- IP65 means it’s comfortable on a garage wall, external wall (under suitable cover), or in a plant area
- Wall-mounting keeps the floor clear, which is handy in smaller garages or commercial plant rooms
- Natural cooling and outdoor rating make it well-suited to Aussie conditions when installed correctly
BSC Renewables will choose a location that’s safe, compliant and easy to access for future checks.
4. Built to Grow With You
The system is modular and expandable up to 32 units in parallel, for a total of 326 kWh of capacity.
That gives you plenty of flexibility:
- Start with one battery if you’re dipping your toe in
- Step up to two or three as you get a feel for how it performs
- Scale out over time if you add EV charging, extra air-con, a pool, or expand your business
You’re not locked into guessing your “forever size” on day one – you can build towards it.
5. Safe LFP Chemistry and Intelligent BMS
Across the Deye low-voltage series, including RW-F10.2, feature highlights include:
- Cobalt-free LiFePO₄ (LFP) chemistry for enhanced safety
- Integrated Battery Management System (BMS) watching voltage, current and temperature
- Cell balancing to extend cycle life
- Environmentally friendly, non-toxic materials
In plain terms:
- The chemistry has a strong safety record compared with older lithium types
- The BMS keeps an eye on the pack and helps protect it from misuse
- You’re buying a battery that’s designed to be charged and discharged every day for many years
