Victron Energy
The go-to for off-grid and remote sites: a robust ecosystem, inverters/chargers and advanced monitoring, ideal off the grid or for broad autonomy.
Beyond the big names, other storage brands meet specific needs: Victron for off-grid and remote sites, Growatt for an economical coupling, and other alternatives. wendows installs them: advice, installation and after-sales by our own teams, subsidies and reduced VAT handled.
Each alternative brand has its area of expertise. Here are the main ones we install in Belgium depending on your project — from the remote site to the economical coupling.
The go-to for off-grid and remote sites: a robust ecosystem, inverters/chargers and advanced monitoring, ideal off the grid or for broad autonomy.
An economical inverter + battery coupling for residential self-consumption. A good-value alternative when budget drives the project.
Other LiFePO4 brands on the market may suit you depending on inverter compatibility and availability. We compare them with the usual references.
Remote site, large autonomy, space or budget constraint: we identify the alternative brand best suited to your case, without dogma.
Each alternative has its strengths: autonomy, price or flexibility. The benchmarks to place these brands against the references, set out by our teams.
Most of these brands rely on lithium iron phosphate, valued for its stability and longevity. Some off-grid configurations use other technologies depending on the use.
Depending on the brand, you tailor the capacity from a few kWh to large off-grid installations. The sizing depends entirely on your project and your site.
Warranties vary from one brand to another, generally on the cycles and the capacity. wendows acts as your relay and specifies the exact terms on the quote.
Victron excels at full autonomy and remote sites, with an inverter/charger ecosystem and advanced monitoring. The off-grid reference.
Growatt aims for an economical coupling for residential self-consumption. A relevant alternative when budget drives the project without sacrificing reliability.
We're not tied to a single brand: we recommend the one that best serves your case, whether it's about price, autonomy or compatibility.

Choosing an alternative brand shouldn't complicate the after-sales. Whatever the manufacturer, our installers fit it to its rules, and we handle the warranty and service directly, just as for the big brands.
Alternative brands answer specific cases, but the major references often remain the safe choice. Compare them, then we decide together at sizing.
An overview of the storage brands we install in Belgium: references and alternatives, by capacity and by budget.
See all battery brands → the referenceStackable modular LiFePO4 battery, a safe bet for residential. The go-to when you want proven modular storage.
Compare with BYD → the all-in-oneAll-in-one 13.5 kWh pack with built-in backup. Worth considering for a turnkey solution with native grid backup.
Compare with Powerwall → the budgetGreat value for money in modular LiFePO4. Often the most affordable alternative among our references.
Compare with Pylontech → to combineA battery only makes sense with good production. Check the sizing of your panels before adding storage.
See solar panels → the guideBefore the brand, the principle: understand how a battery stores your solar surplus and cuts your bill.
All about home storage →When you add a battery to your panels, you're choosing two things: a storage brand and an installer. The major references cover most cases, but some situations call for an alternative: a remote site, a budget constraint or a need for full autonomy.
Victron is the off-grid reference: its inverter/charger ecosystem and advanced monitoring suit off-grid sites or large autonomies. Growatt, for its part, offers an economical coupling for residential self-consumption when budget drives the project. Other LiFePO4 brands can complete the picture depending on inverter compatibility.
"No brand is the best in absolute terms: the right battery is the one that fits your site, your budget and your need for autonomy.
That's where our role as a multi-brand installer matters. We're not tied to a single manufacturer: we recommend the brand that best serves your case, fit it to its requirements and remain your single point of contact for the warranty, the commissioning and the after-sales. No buck-passing between the seller, the manufacturer and the fitter.
One contract, one person in charge. Neutral advice, sizing, ordering the chosen brand, installation, subsidies and after-sales: everything goes through wendows, from the first call until after the warranty.
On the budget side, the gaps depend mainly on the brand, the capacity and the use (off-grid or grid-connected). To get a sense of your project, start from our storage pricing page, then ask for a costed quote: it's the only way to get a fair price, sized to your installation.
The price depends heavily on the brand, the capacity and the use (off-grid or grid-connected) — not just the manufacturer. Here are starting ranges for these alternatives installed by our teams, with subsidies deductible afterwards.

Beyond the major references, we notably install Victron (off-grid and remote sites), Growatt (economical coupling) and other LiFePO4 brands depending on compatibility. We recommend the one that best serves your case, without being tied to a single manufacturer.
Victron is the go-to for off-grid and remote sites: its robust inverter/charger ecosystem and advanced monitoring suit cases where you're aiming for full autonomy or an off-grid installation. It's less a consumer product than a bespoke solution.
Growatt offers an economical inverter + battery coupling for residential self-consumption. It's a relevant alternative when budget drives the project, without sacrificing reasonable reliability. We confirm its suitability for your case during the study.
No: whatever the brand, we fit it to the manufacturer's rules and remain your single point of contact for the warranty and the service. You have just one contact, just as with the big brands.
It all depends on your case: off-grid, tight budget, space constraint or need for autonomy. The major references often remain the safe choice, but an alternative may fit a specific situation better. We decide together at sizing.
Reckon from around €3,500 for ~5 kWh and from ~€6,000 for ~10 kWh installed, depending on the brand and the use. Off-grid installations like Victron are priced on quote. Subsidies and reduced VAT deducted afterwards, depending on your region and your eligibility.
