Why Have Your Home Battery Installed by Off Grid Supply BV?

We assist you with the purchase, installation, and setup of your home battery. We always use YMVKAS cables with a thickness of 4x4mm² or 4x6mm² — often not strictly required, but significantly safer, especially if you plan to expand your system in the future with additional storage capacity.

A home battery is a complex system that must be installed safely by a certified technician. Our installers have completed thousands of installations and have the right expertise. We are NEN 1010 and NEN 3140 certified and are authorized to carry out all electrical work in and around your home.

The home battery is always connected behind a separate residual current circuit breaker. In case of an issue, only the home battery is disabled — not your entire household system.

We offer transparent fixed pricing for home battery installations. For business installations, we generally perform a site visit first.

Home Battery Installation Costs

Our installation costs are transparent and clearly structured. We offer fixed pricing based on different installation packages.

Our Installation Process

✔ Accurate quotation after site visit
It is nearly impossible to provide an accurate quote without an on-site inspection. Photos and videos can give a distorted view of the actual situation.

✔ Site visit for installation assessment
We always conduct a site visit before preparing a quote. The visit costs €139, which will be deducted from your final invoice if you proceed with the installation.

✔ Schedule within 1–2 weeks
After your request, our certified installer will visit your location to assess the situation and provide a non-binding quote. You can also discuss additional requests, such as combining the battery with solar panels or modifying the fuse box.

✔ Agreement and planning
Once you accept the quote, the installation can be scheduled within 1–4 weeks. After payment, we’ll contact you to arrange an installation date.

✔ Transparent pricing
Below you’ll find a clear overview of our standard installation costs so you can anticipate your investment.
