Why Lithium Battery

Why Homeowners Are Moving to a 15kWh Battery

15kWh is the sweet spot of home energy storage — big enough to run a household from sunset to sunrise,
compact enough to hang on a wall or tuck into a garage.

Rising Electricity Bills

Store cheap solar power or off-peak grid energy, and stop buying peak-price electricity every evening.

Unreliable Grid

Blackouts and brownouts are becoming more frequent. A 15kWh battery keeps fridges, lights, Wi-Fi and medical devices running.

Net-Zero Goals

Maximize self-consumption of your solar panels and cut household carbon emissions without changing your lifestyle.

Wasted Solar

 Without storage, most rooftop solar is exported for pennies. A battery keeps that energy for your own evening use.

Our 15kWh configuration

Three Flexible Options for Your Home

One LiFePO4 cell platform, three installation styles. All three routes use automotive-grade cells, a 6,000-cycle @ 80% DOD rating and CAN / RS485 / RS232 communication.

LFF51314 · 16.08kWh
Floor Standing Battery

One cabinet does it all: 16.08kWh in a single floor-standing unit on heavy-duty wheels, with a built-in automatic fire extinguishing device and LED display. IP20 (IP65 customizable). Perfect for whole-home backup and small commercial storage.

3 × 51.2V 100Ah · 15.36kWh
Power Wall Battery

Slim 5.12kWh powerwall modules paralleled side by side on any garage wall. 5kW output per unit, CAN / RS485 / RS232 plus optional WiFi, 4G and Bluetooth monitoring. Ideal where floor space is precious.

3 × 51.2V 100Ah · 15.36kWh
Rack Mounted Battery

Rack-mounted 5kWh modules — the same platform offers 100Ah, 150Ah and 200Ah options, so your system can grow from 15kWh to 30kWh+ by adding modules instead of replacing batteries.

How Long Will a 15kWh Battery Power Your Home?

Based on 14.6kWh of usable energy (15.36kWh configuration at 95% depth of discharge).  Runtime = usable energy /load.

Load Typical Power Runtime on 15kWh Battery
Refrigerator 150W ≈ 97 hours
LED lighting (whole house) 100W ≈ 146 hours
TV + Wi-Fi + router 200W ≈ 73 hours
Essential home loads (night) 500W ≈ 29 hours
Air conditioner 1.5HP 1,200W ≈ 12 hours
Whole home (mixed load) 2,000W ≈7 hours

✔ Rule of thumb: to charge a 15kWh battery in one day, you need about 8 × 450W solar panels with 5 peak sun hours.

Where the 15kWh Battery Works Scene ?

One platform, many home and small-business applications.

Home Solar Self-Consumption

Store daytime solar for evening use and push self-consumption from ~30% to 80%+.

Whole-Home Backup

Seamless backup for fridges, lighting, Wi-Fi and medical devices during outages and extreme weather.

Peak Shaving & Time-of- Use

Charge on cheap off-peak grid power, discharge during expensive peak hours — cut bills even without solar.

Home Office & SmallBusiness

Shops, clinics, farms and home offices that cannot afford downtime — scalable from 15kWh to 30kWh+.

15kWh Lithium Battery FAQ

The questions our customers ask most — answered by LVFU engineers.

How long will a 15kWhlithium battery power a house?

With about 14.6kWh of usable energy (15.36kWh battery at 95% depth of discharge), a 15kWh battery runs essential home loads (fridge, lights, TV, Wi-Fi — roughly 500W) for about 29 hours. A single 1.5HP air conditioner (1,200W) runs about 12 hours. Runtime = usable kWh ÷ load in kW.

About 8 × 450W panels. With 5 peak sun hours and ~10% system losses, each 450W panel generates roughly 2kWh per day, so eight panels cover a full charge in one sunny day. Cloudy regions should size up 20–30%.

LVFU LiFePO4 batteries are rated for 6,000+ cycles at 80% DOD — more than 16 years of daily charging. Every unit carries a 5-year factory warranty.

Yes, for typical households. It covers the essential loads of a 3–4 bedroom home overnight. Homes with heavy daytime consumption (EV charging, all-day AC) can add wall or rack modules later — the system scales without replacing the first battery.

kWh measures energy (how much is stored); kW measures power (how fast it can be delivered). A 15kWh battery with a 5kW output can continuously power appliances with a combined load of 5kW for approximately three hours.

Pricing depends on quantity, configuration (floor-standing / wall-mounted / rack), certifications and destination country. As a factory we offer distributor-tier wholesale pricing — send us your target market and annual volume for a quotation within 24 hours.

LVFU batteries communicate over CAN / RS485 / RS232 and are compatible with mainstream hybrid inverters including Deye, Growatt, GoodWe and LuxPower. Full compatibility list and protocol files available on request.

Yes. LiFePO4 chemistry is thermally stable and does not enter thermal runaway like NMC cells. The built-in smart BMS protects against over-charge, over-discharge, over-current, short circuit and extreme temperatures — and the LFF51314 floor unit adds an automatic fire extinguishing device.
