All-in-one explained

What is an all-in-one inverter battery?

An all-in-one home battery combines the solar charge controller (MPPT), the inverter, the battery and the management systems in a single stackable unit. One product does the work of a separate inverter, battery and controller, with fewer parts to buy, wire and warranty.

The four parts, in one unit

A typical home solar-plus-storage system has several separate components. An all-in-one integrates them:

  • Solar MPPT: converts and optimises the power coming from your panels.
  • Inverter: turns stored DC energy into the 230 V AC your home uses.
  • Battery: LiFePO4 cells that store the energy.
  • BMS and EMS: the battery and energy management that keep it safe and efficient.

All-in-one vs separate components

Buying a separate inverter, battery and controller can work, but it means matching brands, wiring more connections and holding several warranties. An all-in-one reduces the system to one certified product: fewer points of failure, a single warranty, a smaller footprint and a faster install. For a fuller breakdown aimed at installers, see all-in-one vs components.

How it works, day to day

During the day, solar charges the battery (or you charge from cheaper off-peak grid power). In the evening, when tariffs peak, your home runs on stored energy instead of the grid. If the grid drops, the unit keeps your essential circuits running. You manage it from the Sunpura HOME app.

Hybrid or AC-coupled?

If you are planning or building a solar system, a hybrid model (S2400, S4800, S6000) connects panels directly. If you already have solar and want to add storage without rewiring the array, an AC-coupled model (S2400 AC, S6000 AC Pro, U8000 AC) couples on over AC. See the full range.

Frequently asked questions

What is an all-in-one home battery?
An all-in-one home battery combines the solar charge controller (MPPT), the inverter, the battery and the battery and energy management systems in a single unit. Instead of buying and wiring a separate inverter, battery and controller, you install one integrated, stackable product.
Is an all-in-one the same as a hybrid inverter?
A hybrid inverter manages solar, battery and grid power but is still a separate device that needs a matched battery. An all-in-one goes further: the hybrid inverter and the battery are built into one unit, so there are fewer components to specify, wire and warranty.
What does depth of discharge (DoD) mean?
Depth of discharge is how much of the battery you can safely use. A 90% DoD on a 2.4 kWh battery means about 2.16 kWh is usable. Sunpura all-in-one batteries use a 90% depth of discharge.
What does IP65 mean?
IP65 is an ingress-protection rating: the unit is dust-tight and protected against low-pressure water jets from any direction. Sunpura all-in-one units are rated IP65 and operate from -20 C to 55 C.
Can I expand the battery later?
Yes. The stackable models start small and expand by adding battery modules, up to 9.6 kWh (S2400), 14.4 kWh (S4800) or 24 kWh (S6000), and can be paralleled far higher for larger jobs.
Do I need solar panels to use it?
No. You can charge from solar, or charge from cheaper off-peak grid power and use it at peak times, or keep it as backup. Hybrid models connect panels directly; AC-coupled models add storage to solar you already have.
