Model

Think of it as a thirty point seven two kilowatt hour twelve kilowatt power brick: the APOLLO A snaps beside others to scale a home from evening buffer to full-day backup. More than a battery, the twelve kilowatt APOLLO A is a thirty point seven two kilowatt hour building block that clicks into a row as the load grows.

Features

  • Lego for power Each twelve kilowatt block clips to its neighbour, turning a home into a scalable thirty point seven two kilowatt hour plant.
  • Clean drive stage The twelve kilowatt pure-sine inverter feeds two hundred thirty volt loads without humming harm.
  • Long-lived cells LiFePO4 gives the thirty point seven two kilowatt hour pack a decade-class working life.
  • Smart oversight The BMS reads every cell and throttles the inverter before stress builds.
  • Input tolerant Shaky voltage and generator swing are absorbed by the MPPT front end.
  • All-weather From a hot loft to a cold shed the cabinet keeps its output.

Applications

  • Workshop & tools: A pure-sine twelve kilowatt feed starts saws and pumps cleanly, so the workshop runs as if wired to the grid.
  • Small business: Card readers, routers and display lights draw from the twelve kilowatt output, so trading never pauses for an outage.
  • Off-grid cabin: With no mains nearby, the battery and inverter keep a remote cabin lit and working through every nightly cycle.
  • Cold storage: Frozen and chilled goods stay safe on battery through a blackout, with the thirty point seven two kilowatt hour pack holding the cold.
  • Security & lighting: Surveillance, gates and yard lights stay on the battery through an outage, holding a site under watch.
  • Community microgrid: Neighbouring homes wire their cabinets into one pool, sharing a single backup bank through the blackout.

Energy Management & System Architecture

Built as one block, the twelve kilowatt inverter and thirty point seven two kilowatt hour pack need no external combiner — the BMS already bridges them and logs health on the shared bus. A modular bus lets a home begin with a single twelve kilowatt thirty point seven two kilowatt hour block and grow; the BMS re-balances the enlarged bank automatically.

It stores midday PV and releases it after dark on two hundred thirty volt; during a blackout the twelve kilowatt stage swaps in quickly and the BMS keeps every cell in bounds. Solar is the default source, grid or generator the filler, all landing in the thirty point seven two kilowatt hour cells through one input the BMS orchestrates at two hundred thirty volt.

Grid, Backup & System Integration

Off-grid or on, the twelve kilowatt inverter keeps a clean two hundred thirty volt output from the thirty point seven two kilowatt hour LiFePO4 store, and the BMS trips only on a real fault. The unit floats on the grid and disconnects cleanly into island mode, the twelve kilowatt inverter rebuilding a stable two hundred thirty volt wave from the thirty point seven two kilowatt hour pack.

Scaling is mechanical: drop another twelve kilowatt cabinet beside the first and the BMS adopts it, extending both capacity and backup runtime at once. Generator support is built in: if solar and grid both fall short, the MPPT input accepts a genset to recharge the bank while the BMS keeps watch.

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 professional install required?

Minimal — set the twelve kilowatt cabinet down, link more, and connect one AC and one PV line.

Will it handle motor starts?

The twelve kilowatt pure-sine inverter starts pumps and fridges the thirty point seven two kilowatt hour bank buffers.

How quick is backup?

A few milliseconds from grid loss to battery power.

Indoor safe?

Yes. The BMS guards against heat, current and short circuit.
