SMA Solar Technology is a German pioneer of the photovoltaic inverter, renowned for its reliability and longevity. wendows installs its entire range — Sunny Boy, Sunny Tripower, Home Storage and Sunny Portal monitoring — commissions it and remains your point of contact for warranty and after-sales support.
SMA covers the inverter, the storage and the control in a single catalogue. Here are the families we install most often in Belgium, each sized to your roof and your grid.
The benchmark residential string inverter: simple, robust and widely deployed. The safe choice for the single-family home on a single-phase connection.
For three-phase installations and higher power ratings. Designed for the three-phase home or generous roof areas.
The SMA storage solution to keep your solar surplus and boost self-consumption. The inverter + battery pairing scoped right from the study.
Web and mobile supervision of your output, with history and alerts. The software component that makes the installation legible and eases remote support.
Beyond the brand, it is the robustness of the inverter and its efficiency that make the difference. The benchmarks specific to SMA hardware, commissioned by our teams.
SMA specialises in the string (central) inverter: a single unit converts the current of all the panels. A simple, robust architecture that is easy to supervise.
The range spans from small single-phase residential to high-power three-phase, allowing almost any single-family home roof to be equipped.
The stated conversion efficiency is high across the Sunny Boy and Tripower ranges. The exact value depends on the model and on the sizing relative to the panels.
Manufacturer warranty on the inverter, often extendable depending on the model. wendows handles the liaison and the intervention when needed.
Web and mobile supervision included: output, history and alerts. The software component that makes the installation legible and eases remote support.
Depending on the range, the SMA inverter pairs with the Home Storage battery to boost self-consumption. The pairing is scoped at the time of the study.

A reliable inverter deserves careful integration. Our teams wire, configure and commission SMA components to the manufacturer's rules, then handle the monitoring, the warranty and after-sales support directly.
SMA isn't our only string to play. Depending on your roof, your grid and your storage needs, another architecture may suit better. Compare, then we decide together at the study.
An overview of the inverter's role and of the string, hybrid and micro-inverter architectures, to place SMA in the landscape.
All about the inverter → vs SMA stringThe inverter that handles solar and battery in a single unit. A logic to compare with the Sunny Boy + Home Storage combination.
See the hybrid inverter → vs SMA stringOne micro-inverter per panel rather than a central inverter: an opposite architecture, useful on shaded or complex roofs.
See the micro-inverter → vs SMAThe SUN2000 hybrid inverter and the LUNA2000 battery in an integrated ecosystem. An alternative to SMA when you want storage managed as a pair.

All about the home battery → overviewPointers on the complete photovoltaic installation, from panel to commissioning, to frame an SMA-equipped project.
See solar panels →When you equip a roof, the inverter is the component that converts the panels' energy into usable current. SMA, a pioneering German manufacturer, has built a reputation for reliability and longevity on this very component — often exactly what you want when you're after simple, durable hardware.
SMA's strength is a full and coherent range: the single-phase Sunny Boy inverter, the three-phase Sunny Tripower, the Home Storage battery and Sunny Portal monitoring all share the same world. You can start with the inverter alone, then add storage without changing the control logic.
"The best inverter is the one you forget: a reliable component works in silence for years.
This is where our role as an approved installer counts. We size the SMA inverter against your panels and your grid, commission it and remain your single point of contact for warranty and after-sales support. The monitoring helps us intervene remotely as soon as an alert comes through.
A high conversion efficiency. Across 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 budget, SMA sits in the reliable, recognised-component segment. The difference comes mainly down to power and inverter type (single- or three-phase). To frame your project, start from our solar panel pricing page, then request a costed quote.
The price depends mainly on the power and the inverter type (single- or three-phase), and on whether a battery is added — not just on the brand. Here are starting ranges for SMA hardware installed by our teams.

SMA is a pioneering German solar inverter manufacturer, renowned for its reliability and longevity. It is a proven component, widely deployed and easy to supervise. As with any hardware, the result also depends on sizing and commissioning.
The single-phase Sunny Boy inverter, the three-phase Sunny Tripower, the Home Storage battery, Sunny Portal monitoring and the SMA Energy app, plus off-grid solutions such as the Sunny Island. A coherent catalogue covering the inverter, the storage and the control.
Depending on the range, the SMA inverter pairs with the Home Storage battery to boost your self-consumption. If storage is part of your project, we scope compatibility and sizing at the time of the study.
Via Sunny Portal and the SMA Energy app: real-time output, history and alerts. The monitoring also lets us detect an anomaly remotely and respond quickly for after-sales support.
Depending on the model, the manufacturer warranty can run up to 10 years, often extendable. wendows handles the liaison and the intervention. The exact terms are stated on your quote.
Expect from around €1,200 for an installed SMA string inverter, and from ~€5,000 for a battery + inverter set. It all depends on the power and the storage chosen, with grants and 6% VAT deducted afterwards.
