Hybrid inverter: production, battery and grid in one device
The brain of your solar installation. The hybrid inverter converts the power from your panels, charges and discharges the battery, and arbitrates exchanges with the grid — all to maximise your self-consumption. And during an outage, its backup function keeps your essential circuits powered.

Technical specifications
What a hybrid inverter really does
The functions and figures that matter for a well-sized hybrid inverter, fitted by our teams. Concrete benchmarks, not marketing.
- Three roles in one 3-in-1
MPPT (maximum power point tracker) to draw the most from your panels, an inverter to produce 230 V, and a reversible battery charger. A single device arbitrates production, storage and grid instead of three separate units.
- Conversion efficiency > 97% European
DC/AC conversion efficiency exceeds 97% on good models. With DC coupling, the energy goes through only one conversion before the battery: fewer losses than a battery added separately on the AC side.
- Battery-ready Battery-ready
You can install it today with your panels and add the battery later, without replacing the inverter. Check the supported battery voltage range (high or low voltage) to keep your options open.
- Backup function EPS / UPS
During a grid outage, the backup output (EPS) re-powers your essential circuits from the battery and panels. Switchover takes anywhere from a few milliseconds to a few seconds depending on the model and wiring.
- Single / three-phase Single & three
Available in single-phase (most Belgian homes) and three-phase for more powerful installations or charging points. The choice depends on your connection and the power of your panels.
- Self-consumption control Real time
An energy meter continuously measures your consumption and your export. The inverter stores the surplus, gives it back in the evening and limits grid export — at the heart of self-consumption under the prosumer tariff.
* Indicative values for mainstream hybrid inverters. Exact performance depends on the model, the power of the panels and the associated battery — confirmed during the study.

Pros & cons of the hybrid inverter
No solution is perfect for every project. Here, honestly, is where the hybrid excels and where another approach may be enough.
Where it shines
- One smart deviceProduction, storage and grid managed together, without stacking up equipment.
- Ready for the batteryFit the panels now, add storage later without replacing everything.
- Power during an outageThe backup function re-powers your essential circuits when the grid goes down.
- Maximised self-consumptionStores the daytime surplus and gives it back in the evening — valuable under the prosumer tariff.
What to keep in mind
- Pricier than a simple inverterThe charging electronics and the backup function push up the price of the device.
- Worth it mainly with a batteryWithout storage ever planned, a standard inverter may be enough and costs less.
- Battery compatibility to checkThe voltage range (high or low) limits which batteries you can pair: best framed from the start.
- Backup is not unlimitedThe backup power and duration depend on the battery: we size it to your needs.
For which project
Is the hybrid inverter right for you?
It comes into its own as soon as you aim for self-consumption, storage or the security of a backup supply. A few cases where it shines:
-
Solar + battery
You install (or plan) a battery to use your own energy in the evening: the hybrid manages everything and avoids adding a separate battery inverter.
-
Backup needed
You want to keep the fridge, internet and lighting running during an outage: the backup output (EPS) switches over to the battery automatically.
-
Optimise the prosumer tariff
With the Digimeter and the prosumer tariff, exporting earns little: storing and self-consuming your surplus becomes the real lever for savings.
No battery planned just yet?
If storage is not on the agenda in the short term, first compare the inverter range of standard models. And if your panels face different directions or are partly shaded, take a look at the micro-inverter.

Real case · 4-sided house, Wavre
From surplus exported for almost nothing to 70% self-consumption
The customer was exporting his midday surplus to the grid for a trivial value under the prosumer tariff. We replaced his inverter with a hybrid model and added a 10 kWh battery: the surplus is now stored during the day and given back in the evening, and the backup output secures the essential circuits.

How much does a hybrid inverter cost?
The price depends on the power, the number of MPPTs, single or three-phase and the backup function. The hybrid pays off above all when paired with a battery. Here are some benchmarks for a fitted hybrid.

Hybrid inverter FAQ
Your questions about the hybrid
What is the difference between a hybrid inverter and a standard inverter? +
A standard inverter only converts the power from the panels into 230 V. The hybrid adds a reversible battery charger and grid management: at every moment it decides whether to consume, store or export, and it can power the house during an outage. It is a control device, not just a converter.
Can I install a hybrid inverter without a battery today? +
Yes, that is the whole point of being "battery-ready". You fit the hybrid with your panels and it works like a standard inverter. The day you add a battery, it manages it without needing to replace the device — provided you checked voltage compatibility from the start.
DC or AC coupling, what is the difference? +
With DC coupling, the battery connects directly to the hybrid inverter: the energy goes through only one conversion, with fewer losses. With AC coupling, you add a separate battery inverter to an existing installation: more flexible in renovation, but slightly less efficient. The hybrid favours DC coupling.
Does the hybrid inverter work during a power outage? +
Yes, if it is equipped with the backup function (EPS) and connected to a battery. During an outage, it isolates the house from the grid and re-powers the essential circuits — fridge, lighting, internet. The power and duration depend on the battery capacity; an inverter on its own, without a battery, cannot provide backup.
Single-phase or three-phase, how to choose? +
It depends on your connection and the power. Most Belgian homes are single-phase, which is enough for a standard residential installation. Three-phase is needed for high power, a charging point or an already three-phase connection. We check your meter before choosing.
Is the hybrid worthwhile with the prosumer tariff and the Digimeter? +
More than ever. With the Digimeter and the prosumer tariff, energy exported to the grid earns very little. The hybrid, paired with a battery, stores your midday surplus to give it back in the evening: you consume your own production instead of selling it at a loss. It is the main lever for savings today.
