Model

An five point one two kilowatt hour battery and a six kilowatt inverter share one compact cabinet, so the APOLLO B brings two hundred thirty volt backup and self-use solar to a home without a rack or combiner. The APOLLO B pairs a six kilowatt pure-sine inverter with a five point one two kilowatt hour LiFePO4 pack in a single narrow cabinet, ready to wire straight to the consumer unit.

Features

  • Compact all-in-one The six kilowatt inverter, charge controller and a five point one two kilowatt hour LiFePO4 pack share one narrow cabinet, so a home gains backup without a battery room or combiner.
  • Pure sine output The six kilowatt stage feeds two hundred thirty volt loads with a true sine wave, so routers, fridges and medical kit run cleanly through a switchover.
  • Self-developed BMS A multi-protection BMS balances the five point one two kilowatt hour cells and fences off over-current, over-temperature and short circuit across the pack.
  • 6000-cycle chemistry The LiFePO4 cells are rated for daily cycling over thousands of cycles, holding capacity far longer than a lead-acid bank in the same duty.
  • Quick-install modules A module design clips the inverter and battery together in one cabinet, cutting install to a single AC feed and one PV line.
  • Wide input range The MPPT front end takes panels, grid or generator and tolerates a two hundred thirty volt supply from 90 to 280 volt, smoothing weak local lines.

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.
  • Workshop & tools: Power tools and machinery pull a steady two hundred thirty volt wave from the six kilowatt stage, with no flicker on motor start.
  • Small business: Tills, routers and lighting stay up on the six kilowatt supply, so a shop keeps trading through a blackout.
  • Off-grid cabin: Far from the nearest line, the LiFePO4 pack and inverter run a cabin through nightly cycles, fed by panels or a small generator.

Energy Management & System Architecture

Inverter, MPPT and the five point one two kilowatt hour LiFePO4 cells sit on one short BMS bus inside a narrow cabinet, so there is no rack to assemble or combiner to wire. The compact body puts a six kilowatt inverter next to a five point one two kilowatt hour pack on a single controller loop, eliminating shelf space and separate boxes.

While the sun shines it tops the bank at two hundred thirty volt; the moment the grid wavers the six kilowatt stage carries the load and the BMS fences off any weak cell. It self-consumes midday PV, banks the surplus, and during an outage the BMS holds every cell balanced at two hundred thirty volt through constant cycling.

Grid, Backup & System Integration

Backup arrives without a flicker of the lights: the six kilowatt stage shifts the load onto the five point one two kilowatt hour bank the instant a dip is sensed, so the home stays lit. Transfer is clean and quick, so an outage barely registers for the six kilowatt load drawn from the five point one two kilowatt hour cells at two hundred thirty volt.

A single breaker to the consumer unit keeps the install tidy, yet the BMS still oversees charge, discharge and protection across the two hundred thirty volt system. Because inverter and battery share one cabinet, the house tie is a single breaker - reserve grows by standing a second cabinet next to the first, not rewiring the wall.

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

Will it fit a small home?

Yes. The five point one two kilowatt hour pack and six kilowatt inverter live in one narrow cabinet that tucks into a utility space.

How long does the storage serve me?

It runs the essentials for hours nightly and repeats that for years of daily cycling.

Can I grow it later?

Yes. Stand a second six kilowatt cabinet beside the first and the BMS lifts the five point one two kilowatt hour reserve.

Is it safe indoors?

Yes. The BMS guards over-current, heat and short circuit; keep it ventilated.
