Store your energy. Use it when you need it.
With a HyxiPower home battery you store energy for later. Generated during the day by your solar panels, or bought when that fits your energy situation. SolarFast supplies HyxiPower in two lines: a compact modular battery, or a complete All-in-One energy system with battery and hybrid inverter in one design.
More grip on the energy in your home
Your solar panels do not always generate energy at the moment you need it. Midday can bring a surplus, while you use more electricity in the evening. A home battery helps bring those moments closer together. Energy you do not use right away can be stored and made available for your home later. How much you generate matters. When you use that energy matters just as much. We link Frank Energie if you take their dynamic contract or already have one.
A home battery has to fit the rest of your home. So an install at SolarFast does not start with which battery you want to buy, but with what you want to achieve with your energy. Then we look at your solar panels, usage, connection, current inverter and the capacity you need.
Benefits of HyxiPower. How to get more from smart storage at home
Use more yourself
Make smarter use of the energy your solar panels produce.
Automatically managed
The system continuously watches the battery and the energy flows.
Choose what fits
From 5.3 kWh to the All-in-One sizes we install. The table below shows what we fit.
Installation and aftercare
We review your situation: usage, solar panels, connection and wishes. Then we choose All-in-One or modular and the right capacity. We connect the battery and set up the energy system. After handover you can follow the system through the available software.
Capacities we install
We look at your situation first, then at the kWh. Hybrid without full backup, or All-in-One with backup. Single-phase 3.6 or 5 kW, three-phase 10 kW. Frank Energie or Hyxi (optional) for steering: that requires a dynamic contract with Frank Energie.

Starting prices include standard installation and 21% VAT, price level September 2026. If your meter cupboard needs work, that is listed separately in your quote. If you trade power with your battery, you can reclaim the VAT under conditions. Whether that works for you, you can see with the VAT refund check.
How it works
Which HyxiPower fits your home?
Not every home asks for the same setup. That is why SolarFast works with two HyxiPower systems.
The All-in-One HTA is a complete energy system: battery, hybrid inverter and smart energy control as one whole. Available as 10.6 kWh, 15.9 kWh, 21.2 kWh or 26.5 kWh. Choose that line if you want a tidy All-in-One install, a strong three-phase setup, or backup in the design.
The H2 is a separate high-voltage battery that we combine with a matching hybrid inverter. Modular, from 5.3 kWh. Choose that line if you want a separate battery and inverter, to start small, or lots of choice in capacity.
Two lines, one choice
All-in-One HTA: battery, inverter and backup in one design
H2: separate pack, from 5.3 kWh, plus hybrid inverter
The table shows the sizes we install
How large should your home battery be?
The best home battery is not automatically the largest. Which capacity fits depends on your energy use, solar panels, when you use energy, your connection and what you want the battery to do.
That is why SolarFast looks at your situation first, and only then at the kWh. You do not have to work that out yourself in advance. The sizes we install sit in the table above. More on the trade-off: which home battery fits you.
Energy goes where you need it
During the day your home first uses the energy that is available at that moment. A surplus can then be stored in the battery.
In the evening, when your solar panels produce less or nothing, stored energy can be made available for your home.
Depending on the settings, energy can also go into the battery from the grid. Frank Energie or Hyxi (optional) as steering only works with a dynamic contract with Frank Energie.
The Hyxi All-in-One supports a fast switch to backup. Which appliances keep working during an outage is set when we design the install. That is not a promise that the whole home gets backup power by default. More on backup power with a home battery.
From solar now to later
By day your home uses the energy that is there
A surplus can go into the battery
In the evening that power can go back to the house
See what happens with your energy
With the Hyxi energy platform you can follow the system's energy flows. You get a view of battery status without having to sit in technical settings every day.
How full is my battery, where does my energy come from, is everything working as it should: that is in the app. So you do not have to stand next to the battery every day. A large part of the monitoring happens digitally.
Already a customer? The user manual walks you through the app screens, including linking Frank Energie if you take their dynamic contract or already have one.
Storing energy needs proper monitoring
A home battery sits in or around your home for years. So we look at capacity, power, and how the battery watches itself.
Hyxi systems use lithium iron phosphate (LiFePO4). The Battery Management System watches key battery values and steers the system. Depending on the system there are protections against high temperature, overcurrent, over- and discharge and short circuit. The systems are designed with a high protection rating for suitable install locations.
No yearly bill because that is how it is done
A well-installed home battery normally needs little periodic maintenance. There is no oil to change every year, no burner to retune, no filter a technician must replace as standard. That is why SolarFast does not require a yearly maintenance contract for your home battery.
Keep the area around the battery clean and clear, do not block any ventilation, and watch for anything unusual. Technical monitoring is largely done by the Battery Management System and the software.
If something breaks, that is service, not periodic maintenance. SolarFast assesses what is going on. If a fault falls under the applicable product or installation warranty, it is handled under those warranty terms.
Hyxi All-in-One: one system, one design
In a traditional battery setup the pack and hybrid inverter sit as separate parts. On the Hyxi HTA the battery modules, inverter and energy control are designed as a stackable system. That keeps the install tidy and lets the parts work as one.
The hybrid inverter steers energy between solar panels, battery, home and grid. Two to five battery modules, depending on the capacity you choose. The BMS watches the pack. Monitoring via app and web. Backup can be part of the install design; it is not a default for the whole fuse box.
Prefer more freedom in capacity?
Then the Hyxi H2 is interesting. The battery is built from separate modules and combined with a matching hybrid inverter. That gives more capacity choices than the All-in-One series.
The H2 family is modular, from 5.3 kWh. The maker shows stacks into the tens of kWh. That is the family ceiling, not what we typically put in a home. We install the sizes in the table above.
After install you still want to know where you stand
HyxiPower offers a 10-year factory warranty on these battery solutions. The exact terms, performance criteria and any limits differ per product and version. The applicable manufacturer terms decide.
If you have a question or a fault appears, you should not have to work out which maker or supplier to start with. SolarFast stays your first point of contact for the install we supplied.

Frequently asked questions
That depends on your energy use, solar panels, connection and what you want the battery to do. SolarFast therefore looks at your situation first and then advises capacity and version. More on the trade-off: which home battery fits you.
The H2 is a modular battery that we combine with a matching hybrid inverter. On the HTA All-in-One battery and hybrid inverter are designed as a complete system.
The systems are built modularly, but expansion depends on the chosen model, the existing configuration and the technical conditions. Ask SolarFast to include that up front if future expansion matters to you.
That depends on your current install and the chosen Hyxi system. SolarFast checks your existing inverter, connection and PV setup before we advise a configuration.
The Hyxi All-in-One supports backup. Whether and which appliances in your home keep working during an outage depends on how the install is designed and connected. That is not a promise of power in the whole house. More: backup power with a home battery.
A well-installed home battery normally needs little periodic maintenance. Keep the system clean, do not block any ventilation, and watch for anything unusual. The battery is also watched through the BMS and digital systems. SolarFast does not require a yearly maintenance contract.
Then we talk about service. SolarFast can assess what is going on. When a fault falls under the applicable warranty, it is handled under those warranty terms.
