Store cheap power. Use it when it’s expensive.
Halo AC is a 3 kWh battery, expandable to 18 kWh, that plugs into a socket in your home. It charges when power costs less, gives it back when it costs more, and an AI decides the best moment on its own based on your tariff.
Set up in 5 minutes. No building work, no installer. And if the power goes out, your home keeps running.
Plug it in, pick your tariff and forget about it.
Your electricity bill depends on when you use power. Halo shifts part of your usage from expensive hours to cheap ones without you changing your habits.
Plug it in
It plugs into a socket at home and connects to your wifi. No fuse box work, no building work: about 5 minutes.
Tell it your tariff
In the app you choose your supplier and tariff, or PVPC if you’re on the regulated price. That tells it when power is cheap and when it’s expensive.
The AI does the rest
It charges in the cheap hours and discharges in the expensive ones. If prices change, it adapts on its own. You see the saving in the app.
Halo in 40 seconds.
Tests carried out under controlled conditions.
This is how fast it installs.
Charges overnight, discharges at peak time.
Illustrative example using the 2.0TD tariff time bands on working days. Weekends and national holidays are off-peak all day.
If the power goes out, your home keeps going.
Halo doesn’t just save you money on your bill. It comes with a built-in backup outlet to keep the important things running when the grid fails, with nothing else to buy.
Theoretical calculation: capacity ÷ connected load, without conversion losses. In practice it will be a little less. Maximum 1,500 VA output, or 3,000 VA if you add at least one module.
Load test using the backup outlet, under controlled conditions.
Peace of mind when you need it most
During a power cut you can keep the essentials running: fridge, router, lighting, chargers. It’s a standard feature, not an extra.
Start with 3 kWh. Grow to 18 kWh.
Add HYX-MS3000B battery modules whenever you need them, up to 5. Each module adds 3 kWh. Modules add energy and backup time; the power at the socket stays at 800 W.
Halo AC only · HYX-MS3000B modules (max. 5)
With modules, the independent backup outlet rises to 3,000 VA. Theoretical backup times, without conversion losses. Calculated with 3 kWh per unit.
Add modules to my orderSave on your bill and keep the lights on if the grid fails.
What matters when it’s in your home: it’s easy, it’s safe and it lasts.
Plug in and done
It delivers up to 800 W to your home through a socket. With 3 kWh stored, it covers almost 4 hours at full output, or many more at a typical home’s usage.
Power if the grid goes down
It includes an independent backup outlet of up to 1,500 VA. Plug the important things (fridge, router, lights) into that outlet, with nothing else to buy.
Built to last
10,000 cycles and a 10-year warranty. With one cycle a day, that’s more than 27 years of use.
Real safety
LiFePO₄ chemistry, automotive-grade A+ cells, five levels of protection with built-in aerosol suppression, and IEC 62619 and UN38.3 certifications.
Handles any location
Protected against dust and water jets. Works from −20 °C to +55 °C and warms itself up when it’s very cold.
Runs itself
The cloud AI optimises savings with your tariff and usage. Control it from the HYXi app via wifi and Bluetooth, with an LED light that shows its status. AI mode requires the meter.
Set it up with your tariff and see how much you save.
With the meter, Halo works in AI mode and is ready for PVPC. Without it, you set up a TOU schedule with your tariff’s time bands. Pick yours.
Charge in cheap hours and discharge in expensive hours—
Switching to Alumbra Energía: calculated from your bill+ your saving
The two savings add up: the Halo saving doesn’t depend on the supplier, and the tariff switch saving comes on top.
How to set it up, screen by screen.
Ready for PVPC
The PVPC price is known the day before. Halo reads it, finds the cheapest hours to charge and the most expensive to power your home. The more the price varies between hours, the more you save.
Cloud AI algorithm
No schedules to set. The algorithm combines your tariff, the day’s price and your real usage to decide when to charge and when to discharge. AI mode requires the meter.
No meter, TOU mode
Without the meter, you set your tariff’s time bands in the app and Halo’s operating mode for each one. It works with free-market time-of-use tariffs.

Halo AC is the battery. The dual meter is needed for AI mode; without it, Halo works in TOU mode.
Halo AC · 3 kWh
Plug-in battery with built-in inverter, backup outlet and app control. It’s the core of the system: it comes with 3 kWh and expands with modules.
Battery module · +3 kWh
Each one adds 3 kWh to your Halo AC, up to 5 modules: 18 kWh in total. More backup time, and the backup outlet rises to 3,000 VA. The power at the socket stays at 800 W.
Capacidad del sistema: 3 kWh
Dual meter · iDW131 MCT-DW
Measures your usage in real time. It’s needed to run Halo in AI mode. Without it, Halo works in TOU mode with your tariff’s time bands.

What people usually ask before buying.
Do I need solar panels?
No. Halo AC charges from the grid in the cheap hours, so the saving comes from the price difference between time bands. If you have solar, it can also store your surplus.
Does it really not need an installer?
It plugs into a socket and connects to your wifi, and you set it up in the HYXi app. The power at the socket is 800 W.
What if I change supplier?
You change the tariff in the app and the AI reorganises charging with the new prices.
How long will it keep my power on if the grid fails?
It depends on what you connect. With the unit’s 3 kWh, a fridge, router and lights adding up to 200 W would give about 15 theoretical hours; a bit less in practice because of losses.
Can I expand the battery?
Yes. With HYX-MS3000B modules of 3 kWh each, up to 5, you reach 18 kWh in total. Modules add energy and backup time; the power at the socket stays at 800 W and the backup outlet rises to 3,000 VA.
Do I need the meter?
For AI mode, yes. Without the meter you can use Halo in TOU mode: you set the time bands and operating mode in the app according to your contracted tariff.
How is the estimated saving calculated?
With one 3 kWh cycle a day, we multiply the price difference between peak and off-peak hours by that energy. It’s a gross estimate, without VAT or conversion losses, and your result depends on your usage.
