Batterij-Outlet or Solar Outlet?

Batterij-Outlet and Solar Outlet both sell standalone energy hardware. That makes a price comparison look straightforward. Yet the bare product price does not tell you what a complete, working system costs. Look at the exact model, the parts required and whether you can order installation along with it.

The same Sigenergy battery module

On 14 July 2026 the SigenStor BAT 10.0 was listed at Solar Outlet for €3,199 including VAT. The same battery module was listed at Batterij-Outlet for €3,299 including VAT. On this reference date Solar Outlet was therefore €100 lower for the standalone hardware.

This is a battery module, not a fully installed system. Depending on the situation you may also need a Sigen Energy Controller, gateway, meter and installation kit, among other parts. The BAT 10.0 has a usable capacity of 9.04 kWh. When comparing follow-up quotes, put the same controller, phase configuration and remaining components side by side.

The difference sits in the full package

At Batterij-Outlet you can add an installation package directly as a service. The basic package for a home battery up to and including 10 kW costs €1,349 including 21% VAT. It sets fixed limits for the power cable, data cable, surface-mounted conduit and any digging or paving work. Anything outside those limits goes through a quote first.

For the BAT 10.0, the combination of our standalone battery module and the basic installation package comes to €4,648 including VAT. That is still not a complete system price: the controller and other necessary parts have to be added depending on the chosen configuration. That is why we do not place this figure next to an all-in price from Solar Outlet.

Where Solar Outlet is strong

Solar Outlet carries a wide range of standalone solar and battery products. The Sigenergy module we checked was sharply priced and in stock. That is attractive when your installer is already lined up and you know exactly which separate parts you need.

Where Batterij-Outlet works differently

We combine a brand-independent hardware shop with installation as a separately ordered service. This lets you choose the technical configuration first and then see which package price applies to the mounting. Systems above 10 kW and situations outside the fixed package limits go through a quote.

That route is most useful when you do not have an installer yet, or want to pin down in advance what the installation package includes. If you already have an installer, the lowest bare hardware price may weigh more heavily.

How to compare the two shops

For each quote, put the type numbers of the battery, controller, gateway, meter and mounting kit side by side. Then check the number of phases, the power rating, delivery, the scope of installation and any additional work. Only then add up the amounts including VAT.

We check this comparison weekly. If the product price or package contents change, we update the entry or take it down temporarily. That keeps the comparison tied to a concrete reference date.
