MultiPlus & Quattro
The heart of a standalone installation: the inverter/charger handles panels, battery and, where applicable, a generator or the grid. Robust and modular, it's Victron's signature.
Victron Energy is the benchmark for standalone installations and remote sites: robust inverter/chargers, batteries and advanced monitoring, to aim for total autonomy. wendows installs this equipment: advice, fitting and after-sales service by our own teams, with management of subsidies and reduced VAT when the home is eligible.
Victron offers a complete ecosystem built around the inverter/charger, storage and monitoring. Here are the configurations we fit most often in Belgium — sized case by case.

To store energy on a remote site or aim for high autonomy: we size the capacity according to your consumption and production, without depending on the grid.
Victron bets on advanced monitoring: detailed tracking of production, charge and consumption, with fine control. Ideal for mastering a standalone installation.
Remote site, backup, autonomy constraint: Victron lends itself to bespoke setups that mainstream solutions don't cover. We design according to your case.
Beyond power, it's robustness and off-grid flexibility that make the difference. The benchmarks specific to Victron equipment, fitted by our teams.
Victron designs inverter/chargers (MultiPlus, Quattro) that handle panels, battery and the grid or generator in a single device. An architecture built for autonomy.
Victron inverter/chargers deliver a good efficiency, optimised for standalone use. The exact figure depends on the model and the configuration of the installation.
Manufacturer's warranty on the equipment, depending on the range. wendows handles the liaison for any warranty work, as with the other brands.
Victron offers detailed monitoring and fine control of the installation: a real asset for mastering a standalone or off-grid system day to day.
Victron is a recognised benchmark for standalone and off-grid energy, with a robust, durable ecosystem. Seriousness valued on demanding installations.
The Victron ecosystem is highly modular and lends itself to bespoke setups. Ideal off-grid or for specific cases that mainstream solutions don't cover.

Buying good off-grid equipment isn't enough: a standalone system has to be designed and sized precisely. Our installers fit it according to the manufacturer's rules, and we handle the warranty and after-sales service directly.
Victron excels off-grid, but it isn't the right choice for everything. On a standard grid-connected installation, other brands suit better. Compare, then we decide together.

All about the inverter →When you install solar, you choose two things: equipment and an installer. Victron answers the first for a very specific use: autonomy. Where a conventional inverter lives to the rhythm of the grid, the Victron inverter/charger is designed to break free from it, on a remote site or to aim for great independence.
The brand has built its reputation on robustness and modularity. Its ecosystem — inverter/charger, batteries, advanced monitoring — combines for bespoke setups that mainstream solutions don't cover: remote site, extended backup, total autonomy.
"Victron is the equipment for those who want to break free from the grid: on a remote site, its robustness and modularity make the difference.
That's where our role as installer counts. A standalone system has to be designed precisely: we size the inverter/charger, the battery and the monitoring according to your site and your consumption, fit it according to the manufacturer's requirements and remain your single point of contact for the warranty, commissioning and after-sales service. No passing the buck between the seller, the manufacturer and the fitter.
One contract, one person responsible. Design, sizing, ordering the Victron equipment, fitting, subsidies and after-sales service: it all goes through wendows, from the first call to beyond the warranty.
On the budget side, a Victron system is priced mainly according to the scale of autonomy targeted and the storage capacity. To get a feel for your project, start from our panel 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 scale of autonomy, the storage capacity and your site — not just the brand. Here are starting ranges for Victron fitted by our teams, subsidies deductible afterwards.

Victron is the benchmark for off-grid and standalone installations: its robust inverter/charger ecosystem and advanced monitoring suit remote sites or when you aim for great independence from the grid. It's less a mainstream product than a bespoke solution.
This is precisely Victron's terrain: with the right sizing — inverter/charger, battery, sometimes a backup generator — you can aim for total autonomy on a remote site. Feasibility depends on your consumption, your production and your site, assessed during the study.
It's a device that combines an inverter and a charger in a single unit (MultiPlus, Quattro ranges): it handles the panels, the battery and, where applicable, the grid or a generator. This versatility is what makes Victron suited to standalone installations.
It's possible, but it isn't always the most relevant choice: on an installation simply connected to the grid, a conventional inverter (SMA, Huawei) is often better suited and more economical. Victron really comes into its own as soon as you seek autonomy. We decide when sizing.
The manufacturer's warranty on Victron equipment depends on the range, generally around 5 years. wendows handles the liaison and the intervention. The exact terms are set out on your quote.
Allow from around €1,200 for an inverter/charger fitted, but a complete standalone system is priced on quotation according to the scale of autonomy and the storage capacity. Reduced VAT of 6 % on the eligible photovoltaic installation, subsidies deducted afterwards.
