SMA is a long-established German manufacturer of solar inverters, renowned for the reliability of its Sunny Boy (single-phase) and Tripower (three-phase) ranges and for its monitoring. wendows installs this equipment: advice, fitting and after-sales service by our own teams, with management of subsidies and reduced VAT when the home is eligible.
SMA breaks its inverters down into several ranges depending on the size and type of connection of your installation. Here are the configurations we fit most often in Belgium — sized case by case.
The benchmark inverter for a single-phase residential installation: robust and proven, it converts the power from your panels for reliable self-consumption.
For three-phase or higher-power installations: the Tripower spreads production across the three phases, suited to large houses and big consumers.
Production monitoring is done via the SMA portal and app: graphs, history and alerts. Clear monitoring to check everything is working properly.
Depending on the range, the SMA inverter can control a battery to store the surplus. The coupling and compatibility are confirmed when sizing.
Beyond power, it's German reliability and monitoring that make the difference. The benchmarks specific to SMA equipment, fitted by our teams.
SMA designs string (central) inverters: a single device converts the power of the whole solar array. A proven architecture, simple and robust for most roofs.
Sunny Boy and Tripower inverters deliver a high European efficiency, in the region of 98 % depending on the model. The exact figure depends on the power and configuration.
Manufacturer's warranty on the inverter, often extendable depending on the range. wendows handles the liaison for any warranty work.
Monitoring is done via the SMA portal and app: production graphs, history and alerts. Clear monitoring to check performance over time.
SMA is a long-established German manufacturer of the solar inverter, a guarantee of reliability and parts availability. A safe bet over the long term.
SMA inverters pair with a wide range of panels on the market. This compatibility makes it easier to choose modules according to your roof and budget.

Buying a good inverter isn't enough: its performance depends on sizing and commissioning. Our installers fit it according to the manufacturer's rules, and we handle the warranty and after-sales service directly.
SMA isn't our only string. Depending on your roof and budget, other inverter brands may suit you better. Compare, then we decide together when sizing.

All about the inverter → to combineAn inverter is only useful if it's well matched to the panels. Check the sizing of your solar array before choosing.
See the solar panels →When you install panels, you choose two things: equipment and an installer. SMA answers the first with its Sunny Boy and Tripower inverters, German devices renowned for their reliability: they convert the power from your panels to feed your home, day after day, without fuss.
The brand draws its strength from its heritage. SMA is one of the oldest manufacturers of solar inverters: mature R&D, parts available over time and clear monitoring via Sunny Portal. For those who favour a safe bet on the inverter side, it's a benchmark.
"The inverter is the silent heart of the installation: you forget about it as long as it works, and SMA has built its reputation on that peace of mind.
That's where our role as installer counts. We choose the power and type of inverter — single- or three-phase — according to your solar array and connection, fit it according to the manufacturer's requirements and remain your single point of contact for the warranty, commissioning and after-sales service. No passing the buck between the seller, the manufacturer and the fitter.
One contract, one person responsible. Advice, sizing, ordering the SMA inverter, fitting, subsidies and after-sales service: it all goes through wendows, from the first call to beyond the warranty.
On the budget side, the inverter is priced mainly according to its power and type. To get a feel for your project, start from our panel pricing page, then ask for a costed quote: it's the only way to get a fair price, sized to your installation.
The price depends mainly on the power, the type (single- or three-phase) and your existing installation — not just the brand. Here are starting ranges for SMA fitted by our teams, subsidies deductible afterwards.

SMA is a long-established German manufacturer of solar inverters, recognised for its reliability and monitoring. The appeal is a safe bet on the inverter side. As with all equipment, the final performance depends as much on sizing and fitting as on the device itself — hence the importance of an installer.
The Sunny Boy is a single-phase inverter, suited to most residential installations. The Tripower is three-phase and suits higher-power installations or three-phase connections. The choice depends on your connection and the size of your solar array, defined when sizing.
Via the Sunny Portal portal and app: production graphs, history and alerts in the event of a problem. This monitoring lets you check the installation's performance over time and quickly spot a drop in output.
SMA inverters pair with a wide range of panels on the market, which leaves plenty of freedom in choosing modules. We check compatibility with the chosen panels when sizing your installation.
The manufacturer's warranty on the inverter can run up to 10 years depending on the range, often extendable. wendows handles the liaison and the intervention. The exact terms are set out on your quote.
Allow from around €1,200 for a single-phase Sunny Boy fitted, depending on the power and your installation. Three-phase Tripower models are priced according to power. Reduced VAT of 6 % on the eligible photovoltaic installation, subsidies deducted afterwards.
