Micro-inverter: every panel works for itself, without dragging down the others
One micro-inverter per panel converts the direct current into alternating current right at the roof. The result: a panel in the shade of a chimney or a tree no longer holds back the whole installation. The solution for complex, multi-orientation and partly shaded roofs in Belgium — with panel-by-panel monitoring and no high voltage on the roof.

Technical specifications
What a micro-inverter is really worth
The concrete benchmarks of distributed power electronics (MLPE), installed by our teams. Useful figures, not marketing.
- Architecture MLPE 1 per panel
Each panel has its own inverter fixed under the module. The DC→AC conversion happens right at the roof: there is no single large central inverter, and no common weak link across the whole chain.
- Shading management Per panel
Each panel drives its own maximum power point (MPPT) independently. A module shaded by a chimney or a tree produces less, but the others stay at 100% — whereas a string inverter aligns the whole chain on the weakest panel.
- Multiple orientations Unlimited
East/west slopes, L-shaped roofs, several pitches: since each panel is independent, you can freely mix orientations on the same installation without penalising the overall output.
- Safety No HV DC
The current flowing on the roof is low-voltage alternating current, not high-voltage direct current. The risk of an electric arc is greatly reduced and rapid shutdown is made easier for firefighters.
- Monitoring Panel by panel
Each module reports its individual output in the app. You immediately spot a soiled, faulty or shaded panel, with no need to diagnose the whole chain.
- Warranty & lifespan 20–25 years
Micro-inverters are warranted far longer than a central inverter (often 8 to 12 years). And in case of failure, only one module is affected: the rest of the installation keeps producing.
* Indicative values for mainstream micro-inverters. The gains from shading depend heavily on your roof configuration — quantified during the survey.

Pros & cons of the micro-inverter
No technology is ideal for every roof. Here, honestly, is where the micro-inverter excels and where another solution will be more relevant.
Where it shines
- Shade resistantA shaded panel no longer holds back the others: output preserved on a complex roof.
- Free multi-orientationEast/west, several slopes and pitches on the same installation, with no compromise.
- Enhanced safetyNo high-voltage direct current on the roof; electric arc and fire risk reduced.
- Scalable and finely trackedYou add one panel (and its micro) at a time, with module-by-module monitoring.
What to keep in mind
- Higher cost per WpThe distributed electronics cost more than a central inverter, especially on a large installation.
- More components on the roofOne unit per panel, accessible under the modules: more elements over the long term.
- No native storageTo pair a battery simply, a hybrid inverter is often more direct.
- Oversized if everything faces southOn a single, unshaded, full-south roof, the real gain becomes marginal.
For which project
Is the micro-inverter right for your roof?
It comes into its own as soon as the roof is not a perfect, clear plane. A few cases where it makes all the difference:
-
Shaded roof
Chimney, dormer, neighbouring tree, antenna: if part of the panels is shaded at certain hours, the micro-inverter isolates the loss to the single module concerned.
-
Multiple orientations
East and west slopes, L-shaped roof, hips: since each panel is independent, you cover every face without aligning output on the worst one.
-
Scalable installation
Planning to expand later, or to track each panel closely? The micro-inverter is added module by module and is diagnosed individually.
Simple roof, or a project with a battery?
For a single, clear, full-south roof with storage, a hybrid inverter is often more relevant. And to optimise an existing string without replacing everything, look at optimisers.

A shaded east/west roof that finally produces at full power
The roof, split between an east slope and a west slope, was partly shaded by a large oak at the end of the day. With a string inverter, every shadow dragged down the whole chain. We fitted one micro-inverter per panel: each module now produces according to its own sunlight, and the panel-by-panel monitoring revealed two modules that needed cleaning.

How much does a micro-inverter cost?
The price is counted per panel, since you need one micro-inverter per module. The extra cost pays off above all on shaded or multi-orientation roofs. Here are some benchmarks for fitted equipment.

Micro-inverter FAQ
Your questions about the micro-inverter
What is the difference between a micro-inverter and a standard inverter? +
A standard (string) inverter is a single unit that converts the power of a whole chain of panels: if one panel weakens, the whole chain aligns on it. The micro-inverter places a small inverter under each panel, which converts the power individually. Each module then produces according to its own sunlight, independently of its neighbours.
Is the micro-inverter really worth it when there is shading? +
Yes, that is precisely its strength. As soon as a chimney, a dormer or a tree shades part of the roof at certain hours, the micro-inverter isolates the loss to the single panel concerned. On a regularly shaded roof, the production gain commonly reaches 5 to 25% compared with a string inverter.
Can you mix several panel orientations? +
Absolutely. Since each panel manages its own power point, you can freely install east and west slopes, several pitches or an L-shaped roof on the same installation, without the least-exposed face penalising the others. This is one of the technology’s great strengths.
Is the micro-inverter safer? +
Yes. Since the conversion happens right at the panel, it is low-voltage alternating current that flows on the roof, not high-voltage direct current as with a central inverter. The risk of an electric arc is greatly reduced and emergency shutdown (rapid shutdown) for rescue services is made easier.
What happens if a micro-inverter fails? +
Only the panel concerned stops producing; the rest of the installation continues as normal. The panel-by-panel monitoring identifies the faulty module straight away, which makes troubleshooting simple and targeted. Micro-inverters are, moreover, warranted for 20 to 25 years, far longer than a central inverter.
Is the micro-inverter compatible with a battery? +
Yes, but the coupling happens on the alternating-current side, which adds a conversion. If storage is central to your project and your roof is simple and clear, a hybrid inverter will often be more direct and economical. We compare both options together based on your installation.
