What makes the price of an SMA inverter vary
At equal output, two SMA quotes can differ by several hundred euros. Here are the items that really weigh in.
- Range: Sunny Boy vs Tripower vs Storage
The Sunny Boy covers single-phase residential installations. The Tripower is the choice for three-phase setups in large houses and small buildings. The Sunny Boy Storage adds integrated battery management: it is the most expensive range but also the most complete.
See the SMA ranges → - Nominal output (kW-peak)
The higher the output, the more the inverter costs. But a slightly undersized inverter (DC/AC ratio ≈ 1.2) is often more cost-effective: it clips the rare peaks and reduces the total price.
- SMA Portal monitoring
Access to the SMA Sunny Portal or the SMA Energy app is included with most recent models. Installing the Wi-Fi or Ethernet communication module can add €80 to €150 if the access point is far away.
- Extended warranty
The standard SMA warranty is 5 years, extendable to 10 or 20 years. A 10-year extension generally costs €150 to €300 depending on the range. It secures your investment over the full lifetime of the installation.
- Battery compatibility
The Sunny Boy Storage is designed to drive LFP (BYD, Pylontech) or NMC batteries. Planning for the hybrid inverter from the first installation avoids a costly replacement when adding storage.
Sizing your battery → - Certification and grid approval
All SMA inverters are IEC-certified and compliant with the requirements of Belgian grid operators (Ores, Sibelga, Fluvius). This simplifies the commissioning declaration and avoids non-compliance costs.
The grants that lighten your installation with an SMA inverter
The SMA inverter is an integral part of your solar installation: the grants apply to the whole PV system, inverter included. Here are the 2026 benchmarks — we calculate the amount and guide you through the process.
Green certificates (PV support mechanism)
The Walloon support mechanism awards green certificates proportional to production. The SMA inverter, included in the certified system, requires no specific additional step.
- Installation carried out by an approved installer
- IEC-certified inverter declared to the grid operator
- Installation declaration to the CWaPE within the deadlines
Green certificates + Renolution grant
Brussels combines green certificates (10 years) and the Renolution grant for energy renovation. The SMA inverter is eligible as part of the overall PV installation.
- Installation in a home over 10 years old for the Renolution grant
- Certified installer and itemised invoice required
- Declaration to Brugel within the regulatory deadlines

Your questions about SMA inverter prices
How much does an SMA inverter cost in Belgium in 2026?
An SMA Sunny Boy inverter (single-phase) costs between €800 and €1,200 supplied and installed. The Sunny Tripower (three-phase) is between €1,200 and €2,000, and the Sunny Boy Storage (hybrid with battery management) between €1,800 and €2,800. These ranges include installation, cabling and commissioning.
What is the difference between the Sunny Boy and the Sunny Tripower?
The Sunny Boy is a single-phase inverter for residential houses with a standard electrical connection. The Sunny Tripower is three-phase, ideal for large houses and buildings with three phases available. The Tripower is more expensive but balances the load on the grid better and suits high outputs.
Is SMA Portal monitoring included in the price?
Access to the SMA Sunny Portal and the SMA Energy app is included free with recent inverters. Installing the Wi-Fi or Ethernet communication module is an extra of €80 to €150 if the electrical panel is far from the router. We include it in the quote.
What warranty for an SMA inverter?
The standard SMA warranty is 5 years. It is extendable to 10 or 20 years for an extra €150 to €350 depending on the range. SMA is renowned for the reliability of its products and the long-term availability of spare parts.
Is the Sunny Boy Storage compatible with all batteries?
The Sunny Boy Storage is compatible with most LFP batteries on the market (BYD HV, Pylontech) as well as certain NMC batteries. SMA publishes a verified compatibility list: we check it systematically before sizing your hybrid system.
Is VAT reduced for the purchase and installation of an SMA inverter?
Yes. For renovation of a home over 10 years old, VAT is 6% instead of 21% on the whole installation bill (panels, inverter, structure, installation). On a €1,000 inverter, that is a saving of about €150. We check your eligibility from the first contact.
Is it better to choose SMA or another inverter manufacturer?
SMA is a German manufacturer with over 40 years of experience and an excellent reputation for reliability and after-sales service. Compared with Fronius or SolarEdge, prices are comparable; SMA stands out for the long availability of parts and a well-regarded monitoring portal. We present the options suited to your installation.
