Model

The APOLLO C combines a twelve kilowatt inverter with a fifteen point three six kilowatt hour LiFePO4 pack and delivers 110V/230V split-phase output from a single compact unit. One cabinet, two voltages: the APOLLO C supplies 110V/230V split-phase output for appliances and sub-panels from its twelve kilowatt inverter and fifteen point three six kilowatt hour bank.

Features

  • Split-phase for shops The twelve kilowatt stage runs 110V/230V split-phase, so a workshop, stall or small office draws from one cabinet without a separate step-up transformer.
  • Tool-grade wave A true sine output starts motors cleanly; pumps, compressors and POS all see stable voltage through a switchover.
  • Add a block A second twelve kilowatt cabinet bolts onto the same bus to raise the fifteen point three six kilowatt hour total; the BMS treats both as one bank.
  • Bank protection The BMS watches every cell in the fifteen point three six kilowatt hour pack, isolating a weak cell before it drags the rest down.
  • Built to cycle The LiFePO4 chemistry is rated for daily charge and discharge, holding capacity through years of commercial use.
  • Mixed source Panels, grid or a genset all feed the one MPPT inlet, so the fifteen point three six kilowatt hour store tops up from whatever is on hand.

Applications

  • Evening solar self-use: Rooftop generation is captured by day and released after sunset, so more of the fifteen point three six 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 twelve kilowatt stage, with no flicker on motor start.
  • Small business: Tills, routers and lighting stay up on the twelve kilowatt supply, so a shop keeps trading through a blackout.
  • Market stall: A till, scale and lighting run from one quiet cabinet, so a vendor trades anywhere the sun or battery reaches.
  • Off-grid cabin: Off the grid, the fifteen point three six kilowatt hour store carries a cabin or kiosk day and night from panels or a genset.

Energy Management & System Architecture

The APOLLO C keeps one cabinet body and delivers 110V/230V split-phase output, so the twelve kilowatt stage and fifteen point three six kilowatt hour bank match the destination wiring. One cabinet, two voltages: the fifteen point three six kilowatt hour twelve kilowatt cabinet outputs 110V/230V split-phase, serving home, shop and small plant.

On-grid it self-consumes and banks surplus; islanded the twelve kilowatt inverter carries the load while the BMS fences off weak cells. The BMS treats solar, grid and generator as one source and protects the fifteen point three six kilowatt hour pack through constant use on the local line.

Grid, Backup & System Integration

When mains fails the fifteen point three six kilowatt hour store carries the site with no manual switch, the twelve kilowatt stage holding the load until power returns. Blackout response is measured in moments: the twelve kilowatt stage pulls the fifteen point three six kilowatt hour bank online before appliances notice, on the local split-phase standard.

Another cabinet is later added to the same bus, so the fifteen point three six kilowatt hour total rises without fresh wiring or a second controller. The BMS merges every stacked block into one virtual battery, so reserve grows with the physical stack and the feed stays unified.

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 truly split-phase?

Yes. The inverter is built for the 110V/230V split-phase standard from the factory.

Will it lower my bill?

Yes. It banks midday solar and discharges through the evening peak.

What runs in a blackout?

The twelve kilowatt stage keeps essentials alive for hours on the split-phase output.

Indoor safe?

Yes. The BMS isolates faults; keep air moving.
