Electricity bills too high? Power outages too annoying? …This all‑in‑one energy storage system is about to change the way we use electricity at home:
✨ Ready to use out of the box – save on installation labour
All
matching and debugging are completed at the factory. No need for
customers to pair inverters and batteries themselves – no communication
protocol mismatches, no wiring irregularities, and no expensive
professional installation fees.
✨ Plug‑and‑play, a “power bank” you can roll anywhere
No
wall‑breaking, no rewiring, no electrical panel modifications. With a
sleek design and built‑in wheels at the bottom, you can move it from
kitchen to balcony, courtyard to garage – wherever you need power, truly
giving you “freedom of electricity.”
✨ Three sizes to fit your needs – expandable on demand
Available in 5 kWh, 10 kWh, and 16 kWh capacities:
5 kWh – ideal for rental rooms, small apartments, or campervans; enough for emergency lighting, phones, and laptops.
10 kWh – for a family of 3‑4, covers air conditioning, refrigerator, and daily nighttime loads.
16 kWh – for large flats or small shops, runs multiple ACs and production equipment, and can even slowly charge an EV in reverse.
Multiple units can also be paralleled for greater capacity, meeting diverse power demands.
✨ Longer lifespan, safe and reliable
Unlike
traditional stacked designs, our cells are placed vertically and
supported by a sturdy frame, preventing deformation and damage caused by
long‑term compression on bottom cells. With over 6,000 cycles, service
life exceeds 12 years. Equipped with Grade‑A LiFePO₄ cells – no fire
risk, no noise, no odour – safe even in basements.
✨ Smart dispatch, seamless switching
Default
priority: solar power first supplies household loads, with excess
charging the battery; when solar is unavailable, the battery powers
loads; when battery is low, it automatically switches to grid power.
Zero‑second switchover between off‑grid and grid‑tied modes – lights,
refrigerators, and routers keep running instantly during outages.
✨ Powered by the “smartest brain” – full‑scene remote intelligent control
Built‑in
BMS battery manager with multiple protections: over‑voltage,
over‑temperature, short‑circuit, and more. Supports
RS485/CAN/Bluetooth/WiFi full communication. With the mobile app, you
can monitor and manage its status from anywhere, even when you're away.
Good energy storage is not an expense – it's a long‑term investment in the quality of your home electricity.
