"Omvormer" is the Dutch word for inverter — the component that converts the current from your panels. SMA, a German manufacturer, is a benchmark for it. wendows installs SMA inverters across Belgium, on both sides of the language border, and remains your point of contact for warranty and after-sales.
Whether you say "inverter" or "omvormer", the equipment is the same. Here are the SMA families we install most often in Belgium, sized to your roof and your grid.
The benchmark single-phase string inverter for the individual home: simple, robust and widely deployed. The safe bet for residential.
For three-phase installations and high outputs. Designed for the home connected in three-phase or generous roofs.
The SMA home battery to store the surplus and boost self-consumption. The inverter + battery pair framed from the study onward.
Web and mobile supervision of output, with history and alerts. The tool that makes the installation legible and eases remote after-sales.
Inverter or omvormer, the criteria are the same: robustness, efficiency and monitoring. The key points of SMA equipment, commissioned by our teams.
SMA specialises in the string inverter (central omvormer): a single device converts the current from all the panels. A simple, robust architecture.
The range covers everything from small single-phase residential to high-power three-phase, which lets it equip almost any individual home roof.
The stated conversion efficiency is high across the Sunny Boy and Tripower ranges. The exact value depends on the model and the sizing.
Manufacturer warranty on the inverter, often extendable depending on the model. wendows handles the liaison and the intervention if needed.
Web and mobile supervision included: output, history and alerts. The tool that makes the installation legible and eases remote after-sales.
Depending on the range, the SMA omvormer pairs with the Home Storage battery to boost self-consumption. The coupling is framed at the study.

Whether your project is in French or in Dutch, the SMA equipment and our installation standards are the same. Our teams install, configure and commission the inverter according to the manufacturer's rules, then handle warranty and after-sales directly.
SMA isn't the only omvormer option. Depending on your roof, your grid and your storage needs, another architecture may suit. Compare, then we decide at the study.

SMA, a pioneering German manufacturer, is a benchmark for the omvormer. Its range is complete and coherent: the single-phase Sunny Boy omvormer, the three-phase Sunny Tripower, the Home Storage battery and the Sunny Portal monitoring share the same world, easy to expand.
"Inverter or omvormer, it's the same device: the one that makes your panels' energy usable in the home.
This is where our role as an approved installer matters, on both sides of the language border. We size the omvormer against your panels and your grid, commission it and remain your single point of contact for warranty and after-sales, in French as in Dutch.
A high conversion efficiency. On the Sunny Boy and Tripower ranges, little energy is lost between the panels and your distribution board — the exact value depends on the model and the sizing.
On the budget side, the SMA omvormer sits in the reliable, recognised-component segment. The difference comes mainly from power and type (single- or three-phase). To frame your project, start from our solar panel pricing page, then ask for a quote.
The price depends mainly on the power and type of omvormer (single- or three-phase), and on whether a battery is added — not just on the brand. Here are starting ranges for SMA equipment installed by our teams.

Yes. "Omvormer" is simply the Dutch word for "inverter". It refers to the component that converts the direct current from the panels into usable alternating current. In Belgium, both terms are used for the same equipment.
SMA is a pioneering German manufacturer of solar inverters, renowned for its reliability and longevity. It's a proven component, widely deployed and easy to monitor. The result also depends on the sizing and commissioning.
The Sunny Boy is a single-phase omvormer, suited to most individual homes. The Sunny Tripower is three-phase (driefasig) and targets more powerful installations. The right choice depends on your grid and the panel output.
We operate everywhere in Belgium, on both sides of the language border. The SMA equipment and our installation standards are the same, whether your project is in French or in Dutch.
Depending on the range, the SMA omvormer pairs with the Home Storage battery (thuisbatterij) to boost your self-consumption. If storage is part of the project, we frame the compatibility at the study.
Expect from around €1,200 for an installed SMA string omvormer, and from ~€5,000 for a battery + inverter set. It all depends on the power and the storage, with subsidies and 6% VAT then deducted.
