SMA Home Storage is the storage solution of the SMA ecosystem: it keeps your panels' surplus to deliver it back in the evening, clearly boosting your self-consumption. wendows sizes, installs and configures the battery, and remains your point of contact for warranty and after-sales support.
A battery doesn't just store: it changes the way you consume your solar. Here are the configurations we install most often in Belgium, sized to your consumption.
The surplus produced during the day is stored and then returned in the evening, when the panels no longer produce. That is the heart of a residential battery's value.
The battery integrates with the SMA ecosystem and talks to the inverter. The pairing is coherent, controlled from the app, with no stacking of brands.
With a hybrid inverter, the installation is ready to take storage from the outset or later, without replacing the heart of the system.
The app shows the charge level and arbitrates between consuming, storing and exporting. Storage becomes legible and is tuned to your habits.
Beyond the stated capacity, it is the integration and the control that make a good battery. The benchmarks specific to SMA Home Storage, installed by our teams.
Lithium home battery, the benchmark technology for residential storage: good density, long service life and many charge cycles.
The capacity is sized to your consumption and your solar production. We set the battery size as precisely as possible at the study, without oversizing.
The charge/discharge efficiency of a lithium battery is high: little energy is lost between storing the surplus and returning it in the evening.
Dedicated manufacturer warranty on the battery, expressed in years and/or cycles depending on the model. wendows handles the liaison and the intervention.
The battery is designed for the SMA ecosystem and talks to the inverter. A coherent pair, controlled from the app, with no stacking of brands.
Charge level, surplus arbitration and real-time tracking from the SMA Energy app. Storage becomes legible and is tuned to your habits.

A poorly sized battery pays back poorly. Our teams calculate the usable capacity to suit your consumption, install and configure SMA Home Storage to the manufacturer's rules, then handle the warranty and after-sales support directly.
Storage isn't just down to a brand. Depending on your inverter, your consumption and your budget, another solution may fit. Compare, then we decide together at the study.

See solar panels →Without a battery, the surplus produced during the day goes to the grid, often at a low price. SMA Home Storage stores that surplus to return it in the evening, when your panels no longer produce. The result: you consume more of your own energy instead of buying it back.
The appeal of an SMA battery is its integration: it talks to the brand's inverter and is controlled from the SMA Energy app. No mismatched stacking — a coherent pair that arbitrates on its own between consuming, storing and exporting.
"A well-sized battery doesn't store as much energy as possible: it stores exactly what you'll consume again in the evening.
This is where our role as installer counts. We size the usable capacity to your real consumption — a battery that's too big pays back poorly — then install, configure and remain your single point of contact for warranty and after-sales support.
Self-consumption clearly increased. By returning in the evening the surplus stored during the day, SMA Home Storage increases the share of solar consumed on site — the exact gain depends on your profile and the installed capacity.
On budget, the battery + inverter set accounts for the bulk of the cost of a storage project. The return depends on your consumption profile. To frame your project, start from our pricing page, then request a costed quote on a case-by-case basis.
The price depends mainly on the usable capacity and the pairing with the inverter — not just on the brand. Here are starting ranges for SMA hardware installed by our teams.

It stores the solar surplus produced during the day to return it in the evening, when your panels no longer produce. You consume more of your own energy instead of buying it back from the grid, which increases your self-consumption.
Home Storage is designed for the SMA ecosystem and talks to the brand's inverter. With a hybrid inverter, the installation is ready to take storage. We scope compatibility at the time of the study.
It depends on your consumption and your solar production. A battery that's too big pays back poorly. We size the usable capacity as precisely as possible during the survey, based on your real readings.
Via the SMA Energy app: charge level, surplus arbitration and real-time tracking. Storage becomes legible and is tuned to your habits, from your smartphone.
The battery comes with a dedicated manufacturer warranty, expressed in years and/or cycles depending on the model. wendows handles the liaison and the intervention. The exact terms appear on your quote.
Expect from around €5,000 for an installed battery + inverter set, depending on the capacity chosen. The return depends on your consumption profile, with grants and 6% VAT deducted afterwards.
