Choosing the right storage battery installer in Namur (5000) means guaranteeing honest sizing, a safe installation and after-sales that actually answers. At Wendows, it’s salaried technicians — not subcontractors — who study your consumption profile, check your inverter’s compatibility and fit your battery to the highest standard, from the villas of Wépion to the homes of Jambes.
Installing a storage battery in Namur isn’t something to improvise : you have to read your production and consumption readings, check your hybrid inverter’s compatibility, secure the connection and configure the back-up. It’s a job for a qualified electrician, not a simple plug-in — and that’s why we work with salaried technicians, never passing fitters.
Before any quote, the same person who will fit your battery comes to study it at your home, within 48 hours and with no call-out fee. They size the capacity on your real figures — not on a catalogue — and recommend reliable brands proven in the Namur area, from the equipped villas of Wépion to the homes of Jambes.
The criteria that make a good installer
Sized on your profileA serious installer starts from your real production and consumption readings, not a standard capacity : this is what separates a profitable battery from an oversized one.
Safety & proven brandsCompliant connection, protection against lithium thermal runaway and reliable brands compatible with your hybrid inverter : safety is not optional.
Certified rather than amateurQualified, salaried electricians, verifiable local references and written warranties : enough to avoid the botched installations that wreck after-sales and resale value.

Grants & support
An installer who optimises your support in Namur
Namur comes under the support schemes of Wallonia. A good installer doesn’t just fit : they secure the reduced VAT and calculate your profitability against the prosumer tariff. Here is what we optimise for you, with no paperwork on your side.
6 %VAT
Reduced VAT properly applied
For a home over 10 years old in <strong class="text-ink font-semibold">Wallonia</strong>, VAT drops from 21% to 6% on the supply and installation. A declared installer applies it directly and correctly on your quote — an amateur, rarely.
Prosumer tariff
Profitability calculated, not promised
In <strong class="text-ink font-semibold">Wallonia</strong>, the prosumer tariff taxes your use of the grid. We quantify the self-consumption gain your battery really delivers, quote in hand — a serious installer shows the figures before you sign.
Qualified
A compliant, insured installation
Work carried out by qualified electricians in <strong class="text-ink font-semibold">Wallonia</strong>, insured and guaranteed : the condition for a safe, lasting installation with no nasty surprises at resale.
2026 grant guidance — amounts and rules are indicative, to be confirmed for your case.
The full breakdown of amounts, the prosumer tariff and storage profitability is on our battery pricing & profitability page. We calculate your self-consumption gain and your return on investment before any signature.

Choosing your battery installer in Namur — your questions
How do I choose a good battery installer in Namur? +
Check three things : who actually fits it (salaried, qualified technicians, not passing subcontractors), how the capacity is sized (on your real meter readings, not a standard figure) and what is guaranteed in writing (equipment, installation and after-sales). At Wendows, the person who studies your project in Namur is also the one who fits it and handles the follow-up.
How do you size my storage battery? +
We start from your real solar production and consumption readings, your evening usage profile and your back-up needs. We also check your hybrid inverter’s compatibility. This is what avoids an oversized battery — common when the installer works from a catalogue — and guarantees profitability against the Walloon prosumer tariff.
Which battery brands do you install, and are they reliable? +
We install lithium battery brands proven in the Namur area, chosen for their reliability, lifespan and compatibility with common hybrid inverters. During the study, we steer you towards the solution best suited to your installation rather than an imposed brand — and we explain why.
What warranties does your battery installation offer? +
You benefit from the manufacturer warranty on the battery (capacity and duration varying by brand) and from our warranty on the installation and connection, all in writing. As it’s our own salaried technicians who carry out the work, the same contact answers any question — not an untraceable subcontractor.
Do you handle after-sales after installation in Namur? +
Yes. After-sales is handled by the same team that fitted your battery, based in the Namur region. Installation follow-up, adjustments, back-up configuration and intervention if needed : you keep a single contact from the study throughout the life of your battery, everywhere in the conurbation.
