Model

The five point one two kilowatt hour six kilowatt APOLLO A stacks into a home as one cabinet, pairing a pure-sine inverter with a LiFePO4 bank so rooftop solar becomes stored, switchable power. Designed for whole-home resilience, the five point one two kilowatt hour six kilowatt APOLLO A folds inverter, charge controller and battery into a single stackable block for buildings.

Features

  • Stackable backbone Each six kilowatt cabinet clicks to the next, so a home scales its five point one two kilowatt hour base into a larger bank without rewiring.
  • Pure-sine drive The six kilowatt inverter delivers clean wave output that suits sensitive electronics across a two hundred thirty volt supply.
  • Daily-cycling LiFePO4 The five point one two kilowatt hour cobalt-free pack is built for everyday charge and discharge.
  • Self-developed BMS A proprietary BMS watches each cell and coordinates the inverter, keeping the five point one two kilowatt hour bank balanced.
  • Wide PV window The charge controller rides weak or unstable grids and pairs with rooftop arrays or a small generator.
  • Climate proof Stable output holds in garages and cabins where temperatures swing.

Applications

  • Whole-home backup: A blackout barely registers: the six kilowatt inverter hands the load to the five point one two kilowatt hour bank in moments.
  • Evening solar self-use: Rooftop generation is captured by day and released after sunset, so more of the five point one two kilowatt hour store serves the home itself.
  • Peak-period bill cut: It stores cheap midday power and gives it back when prices climb, smoothing the peak-demand charges on the account.
  • Annex & outbuilding: A shed, studio or guest wing shares the main bank, so outbuildings stay powered without a separate box.
  • Large residence: Stacked cabinets cover a villa or multi-room home, meeting the full five point one two kilowatt hour demand from one tidy row.
  • Workshop & tools: A pure-sine six kilowatt feed starts saws and pumps cleanly, so the workshop runs as if wired to the grid.

Energy Management & System Architecture

Inside the cabinet a six kilowatt inverter, an MPPT stage and the five point one two kilowatt hour LiFePO4 pack share one bus under a self-developed BMS. The BMS balances every cell and isolates a fault before the six kilowatt stage feels it. A stackable design means the five point one two kilowatt hour store is really several six kilowatt blocks on a common BMS. Each block reports cell voltage and temperature, so the controller sees the whole bank as one object.

While the grid is present the unit inverts panel energy to two hundred thirty volt and tops the five point one two kilowatt hour bank; on a drop it shifts to backup within moments, keeping a home's essentials alive. Charging flows from solar first, then grid or generator, all through one tolerant input; the BMS decides the mix and protects the five point one two kilowatt hour cells through constant daily use.

Grid, Backup & System Integration

Backup is seamless: the six kilowatt inverter detects a grid loss and moves the load to the five point one two kilowatt hour battery in a few milliseconds, so lights and routers never blink. Because the BMS already spans the row, adding a six kilowatt cabinet simply lengthens the same backup string protecting a home at two hundred thirty volt.

Integration stays simple — one AC port to the home and one PV port to the array — yet the BMS still coordinates charge, discharge and protection across the two hundred thirty volt system.

Warranty

We provide a 5-year warranty on the battery and a 2-year warranty on the inverter of this product. If you experience any quality issues within the warranty period, please contact us and we will arrange a replacement or repair promptly.

Frequently Asked Questions

Can I really stack more later?

Yes. Each six kilowatt cabinet clips to the next and the BMS merges it, so the five point one two kilowatt hour total grows without new wiring.

How long does the five point one two kilowatt hour battery last in an outage?

It carries essentials for hours and repeats that routine for years thanks to LiFePO4 cycling.

Will it run my whole home?

The six kilowatt inverter drives lighting, fridge and routers together on two hundred thirty volt.

Is it safe indoors?

The BMS guards over-current, over-temperature and short circuit; mount it ventilated.
