Model

Built for the 110V/230V split-phase standard, the APOLLO C gives a home twelve kilowatt backup and thirty point seven two kilowatt hours of stored energy. The APOLLO C wraps a twelve kilowatt inverter and a thirty point seven two kilowatt hour LiFePO4 pack into a single unit that outputs 110V/230V split-phase power.

Features

  • Two-voltage home One cabinet delivers 110V/230V split-phase, running the kitchen outlets and the 230V dryer or well pump together.
  • Clean supply Sensitive electronics ride a true sine; TVs, routers and medical kit draw steady power through the switchover.
  • Grow the bank Add a twelve kilowatt cabinet to lift the thirty point seven two kilowatt hour store; the link is the same one the first unit already uses.
  • Cell balance A BMS keeps the thirty point seven two kilowatt hour pack even, so the full rated capacity stays usable year after year.
  • Daily duty The LiFePO4 pack is built to charge every noon and discharge every night.
  • Tolerant inlet Shaky supply is handled by the charge stage; the inverter keeps a steady output even when the wall feed wanders.

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 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 thirty point seven two kilowatt hour store carries a cabin or kiosk day and night from panels or a genset.
  • Water pump: A bore or irrigation pump draws a clean two hundred thirty volt wave from the twelve kilowatt output, running on stored sun.

Energy Management & System Architecture

A profile-aware BMS reads the supply and sets the twelve kilowatt inverter and thirty point seven two kilowatt hour cells to local limits, trimming current and heat to those rules. Inside, a twelve kilowatt inverter, MPPT and the thirty point seven two kilowatt hour LiFePO4 pack share a bus the BMS tunes to the installed split-phase standard.

By day it banks PV and replays it after sunset; during a blackout the twelve kilowatt stage engages quickly and the BMS keeps each cell within bounds. Each day it turns sunlight into power and tops the bank; away from mains the twelve kilowatt output powers the site while the BMS guards every cell.

Grid, Backup & System Integration

The unit rides the grid and steps into island mode on its own, the twelve kilowatt inverter rebuilding a steady split-phase wave from the thirty point seven two kilowatt hour pack. Backup switches over the instant the grid fails: the twelve kilowatt stage moves the load to the thirty point seven two kilowatt hour battery before a lamp dims, on the 110V/230V split-phase output.

Generator support is built in: if solar and grid both run short, the inlet accepts a genset to recharge while the BMS keeps watch. One feed wire to the panel and one to the array keep the install lean in any home, while the BMS quietly governs charge, discharge and protection across the 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 it charge from a generator?

Yes. The single inlet accepts a genset when solar runs short.

Is the thirty point seven two kilowatt hour pack built for daily use?

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

Expandable?

Add a twelve kilowatt cabinet; the BMS adopts it and lifts the thirty point seven two kilowatt hour total.

Safe to live with?

Yes. The controller isolates faults on its own; set it where air can circulate.
