Model

Built around a self-developed BMS and a six kilowatt inverter, the APOLLO B stores fifteen point three six kilowatt hours and rides a outage on a clean two hundred thirty volt wave. One cabinet holds inverter, charge controller and a fifteen point three six kilowatt hour battery, giving a home six kilowatt backup that switches on the moment the grid drops.

Features

  • Fits the home A six kilowatt unit and fifteen point three six kilowatt hour pack in one narrow cabinet disappears into a corner yet still carries the evening load.
  • Safe output The six kilowatt stage feeds two hundred thirty volt loads with a clean sine; motors start smoothly and LEDs do not buzz.
  • Grow on demand Clip another six kilowatt cabinet to grow the fifteen point three six kilowatt hour store; the link is the same one the first unit already uses.
  • Guardian BMS Over-current and heat are fenced off across the fifteen point three six kilowatt hour cells; a fault trips the bad cell, not the whole home.
  • Long chemistry LiFePO4 gives years of nightly use; it is the chemistry chosen for buses and grids because it simply lasts.
  • One cable in Solar, mains and generator meet at a single port; installers run one line instead of a tangle of feeds.

Applications

  • 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.
  • Annex & outbuilding: A shed, studio or guest wing shares the main bank, so outbuildings stay powered without a separate box.
  • Cold storage: During an outage the fifteen point three six kilowatt hour bank keeps freezers and fridges cold, protecting perishable stock.

Energy Management & System Architecture

A self-developed BMS binds the six kilowatt stage to the fifteen point three six kilowatt hour cells, trimming current and heat so the pack ages slowly. Everything closes inside one cabinet face: the six kilowatt inverter, the charge controller and the fifteen point three six kilowatt hour LiFePO4 bank, all logged by the BMS.

Grid-tied it stores and replays solar; islanded the six kilowatt inverter feeds the essentials while the BMS seals off failing cells on two hundred thirty volt. It loads at noon and discharges after sunset at two hundred thirty volt; in a blackout the six kilowatt stage reclaims the home fast while the BMS nurses each cell.

Grid, Backup & System Integration

The unit rides the grid and falls into island mode on its own, the six kilowatt inverter rebuilding a stable two hundred thirty volt wave from the fifteen point three six kilowatt hour pack. When the mains drops, the fifteen point three six kilowatt hour store carries the home with no manual switch, the six kilowatt stage holding two hundred thirty volt until supply returns.

A generator input is built in: if solar and grid both run short, the inlet takes a genset to recharge while the BMS keeps watch. A second cabinet can later dock beside the first, so the fifteen point three six kilowatt hour reserve doubles without extra wiring or a separate controller.

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

Is it expandable?

Begin with the fifteen point three six kilowatt hour block and add six kilowatt cabinets as demand rises.

Can it take a generator?

Yes. The one PV inlet also takes a portable genset.

Is the fifteen point three six kilowatt hour pack built for daily use?

It is made for exactly that - nightly charge and discharge.

Indoor safe?

Yes. The BMS fences off faults; mount it where air flows.
