What does a HYXi Power home battery cost?

The price depends on capacity, backup option and your fuse box. You get a tailored quote. Request one with no obligation and we'll run your numbers.

Does HYXi Power work with my solar panels?

Yes. The system works with solar panels, the grid, dynamic contracts and energy management systems. We connect everything properly during installation.

Do I have backup power during an outage?

Only if you choose it. Hybrid backup typically covers two circuits; with All-in-One your full fuse box can stay active. Without backup there is no power during an outage.

Does the battery restart automatically after a power cut?

Yes. When grid voltage returns the system starts up again automatically and resumes normal operation.

Do I need to maintain the battery myself?

No. The HYXi Power home battery is maintenance-free. You do not need to perform any maintenance yourself.

How long can my home run on the battery during an outage?

That depends on battery capacity, your home's energy use and which appliances are running at the time. We size the system to your situation.

Can I link HYXi Power to Frank Energie?

Yes. Frank Energie is our energy partner. After installation you can link the battery through the Frank Energie app for smart charging on dynamic rates.

How long does installation take?

Usually within three weeks after approval. Our installers fit the system by your fuse box and walk you through the app.

Smart storage with HYXi Power

With HYXi Power you store daytime solar power for the evening, charge during cheap hours and keep control of your energy bill. The system works with solar panels, the grid, dynamic energy contracts and energy management systems (EMS).

Why HYXi Power through SolarFast?

HYXi Power combines a hybrid inverter and battery in one system. The app shows when your battery is charging, discharging or exporting. We size capacity to your usage and fuse box, and enable backup only when it fits your needs.

Benefits of HYXi Power

More self-use: Use your solar surplus in the evening instead of feeding it back at low rates.
Dynamic charging: With a dynamic contract you charge cheaply and discharge when prices peak. Frank Energie linking available.
Optional backup power: Choose hybrid backup (two circuits) or an All-in-One with your full fuse box on backup power.
Maintenance-free: No periodic maintenance required. 10-year factory warranty on battery modules.

Our Approach: Personal and Tailored

We review your usage profile, existing solar panels and fuse box. Then we advise the right HYXi Power setup: capacity, backup and any Frank Energie linking.

About your home battery

Congratulations on your HYXi Power home battery. With this system you can store energy and use it at the moments that are financially or practically most beneficial.

The system can work together with:

Solar panels
The electricity grid
Dynamic energy contracts
Energy management systems (EMS)

What does your home battery do?

The home battery stores energy so it can be used at a later moment.

The energy can come from:

Solar panels that generate energy during the day.
Cheap power from the electricity grid.
Automatic energy trading via imbalance tariffs.

The stored energy can then be used when:

The solar panels generate little or no energy.
The electricity price is high.
The electricity grid temporarily fails (only on systems with a backup function).

Important to know:

Not every home battery includes backup power as standard. Whether you have backup power depends on the type of installation you chose (for example a hybrid system with or without backup).

Without this option the battery provides no power during an outage.

With backup function (backup power)

Without backup function (no backup power)

During a power outage (hybrid with backup)

When the electricity grid fails, the system automatically detects the outage. With a backup installation we can keep part of your home powered, based on your wishes.

Hybrid backup installation:

The system automatically detects the outage.
The battery switches over to backup power.
2 circuits in the home keep working.
Switching over takes 0.01 seconds.

Appliances often connected to backup power:

Fridge and freezer
Lighting
Internet and router
General sockets
Central heating boiler

Heavier appliances are usually not connected to backup power:

Induction hob
Heat pump
EV charging station
Sauna or whirlpool

With hybrid backup installations, typically a maximum of two B16 circuits can be supplied with backup power.

Full backup with the HYXi All-in-One system

With a HYXi All-in-One system the entire fuse box can be placed on backup power. This means all circuits in the fuse box can stay active during an outage.

Examples of appliances that can then keep working:

Induction hob
Heat pump
EV charger
Air conditioning
Sauna or whirlpool

Complete user guide for the HYXi app

Overview of the energy flow

The overview screen directly shows the energy flows: solar generation, household consumption and whether the battery is charging or discharging.

Charging the battery

The battery stores energy when there is a solar surplus, or when the system is trading and cheap power is being bought.

Discharging the battery

By default the battery discharges when there is not enough solar energy available.

Solar panel information

View the technical data of your solar panels, such as current power, voltage and current, provided they are connected directly to the battery's inverter.

Battery information

Here you see key battery information, including the charge percentage (SOC), the power and the health (SOH).

Grid information

This screen shows information about the grid connection, such as the power drawn or exported and the voltage and current per phase (L1, L2, L3).

Statistics and charts

Analyse in charts how much energy was charged or discharged by switching between day, week, month and year views.

With the HYXi app you can easily monitor how your energy is used. You can see when the battery charges or discharges and how much energy is drawn from the grid.

Solar panel production is not always visible when the panels are not connected directly to the system.

Examples from the HYXi app

Recognise your own situation in the app with these practical examples.

Battery discharging

Situation 1 | Panels power the home, battery discharges alongside

The panels do not generate enough for total consumption. The battery steps in to make up the shortfall.

Battery charging

Situation 2 | Home powered and battery charging

Generation exceeds consumption. The surplus is stored in the battery (2.54 kW, 71%).

Exporting to the grid

Situation 3 | Battery full, surplus power back to the grid

The battery is nearly full (90%). The extra generation (5.94 kW) is exported to the electricity grid.

Explained: dynamic costs & usage

The dynamic part:

There we show a chart of your actual costs and usage up to that moment. If you select 'month' at the top you see your actual costs per day, and if you select 'day' you see the actual costs per hour or quarter hour, depending on your contract.

Just like on your invoice we use the market price+. Energy tax and other fixed costs are not included here.

Under Costs you see:

The costs for gas and electricity.
The costs or earnings from exporting.

For electricity usage:

A positive amount means costs.

For exporting:

A positive amount means earnings.
A negative amount means costs.

Here we explain how to link your home battery to the Frank Energie app and which steps to follow.

Step 1:

Open the Frank Energie app.

Step 2:

Go to the 'Smart Home' tab and tap 'Add device'.

Frank Energie app: this month's overview

Step 3:

Tap 'Home battery'.

Step 4:

Thuisbatterij laten installeren: Het eerste contact met Marco is positief. Hij reageert telkens vliegensvlug op al mijn vragen, ook in de avond en het weekend, dus Marco: dat mag wel iets minder! De installatie verliep niet vlekkeloos, maar wel naar tevredenheid. De monteur is supernetjes en vriendelijk en gaat door tot het netjes klaar en afgerond is. De prijs is concurrerend. Prima partij die mij betrouwbaar overkomt.

Good contact with Raymond, quickly agreed on the price of a Hyxipower 10kWh battery, which was then delivered quickly and neatly installed by Team Ali. So far so good. The battery works well after a lot of searching in the app, but that is not Solar Fast's fault.

On April 22, 4 solar panels were installed at our location by 2 employees from SolarFast. The work started exactly on time and was carried out neatly and quickly. Afterwards, a good explanation was provided at an installed site to monitor
