Energy storage and charging

Power when you need it, even when the grid is full

EPOWER installs charge points and battery storage, at home and on business parks. Every project starts by measuring what you actually use, because an installation chosen on an assumption rarely pays for itself.

  • We measure first, then propose

  • A straight no if it will not pay for itself

  • A fixed price before we start

What you can expect from us


  • We measure before we choose

    Your connection does not limit how much you use in a year, it limits how much you may draw at any one moment. Almost nobody knows where that peak sits without measuring it, so that is where every project starts.

  • A no when the answer is no

    If your consumption is flat, there is no peak to flatten. If your connection can be upgraded and that works out cheaper, we will say so. That costs us an order and it saves you an installation that does nothing.

  • The price is fixed before we start

    No headline price that turns out to be something else. With a charge point the money sits in the metres of cable in between, and we only know that after a visit. After that the amount stands.

Most asked for by businesses

Three things that come back in nearly every business project. The full overview is under Business.


  • Battery storage for business

    What you get

    • A measurement of your consumption pattern before anything is chosen
    • A system sized on your peaks, not on a standard size
    • Installation, connection and commissioning
    Go to Battery storage for business
  • Charging infrastructure for business

    What you get

    • A calculation of what your current connection can take
    • Charge points matched to how long vehicles actually stand
    • Load balancing, so the points do not get in each other's way
    Go to Charging infrastructure for business
  • Energy monitoring

    What you get

    • Measurement per quarter of an hour at the points that matter
    • A readable overview of your peaks, not just raw data
    • A report after the first month covering what stands out
    Go to Energy monitoring
  • Solar panels for business

    What you get

    • A structural check on what your roof carries, before a quote is written
    • A yield calculation alongside your own quarter-hourly measurement, not just an annual total
    • The application to your grid operator and the answer that comes back
    Go to Solar panels for business

Most asked for by households

A charge point at home and storage for the solar power you generate, with a calculation on your own consumption first.


  • Charge point at home

    What you get

    • A check of your meter cupboard and consumer unit beforehand
    • A fixed price before we start, cabling included
    • Fitting, connection and handover with a test run of the installation
    Go to Charge point at home
  • Home battery

    What you get

    • A calculation on your own consumption, not on an example household
    • A system sized on what you use in the evening
    • Installation, connection and pairing with your inverter
    Go to Home battery
  • Solar panels

    What you get

    • A yield calculation for your roof, with the shade of your own surroundings in it
    • A panel choice that follows from that calculation, not from a stock list
    • Mounting, connection and the notification to your grid operator
    Go to Solar panels

How a project runs


  1. We look at your situation

    At a home that means a visit: where the car is parked, where the meter cupboard sits, what the consumer unit can take. At a business it means measuring your consumption per quarter of an hour, for a month at least.

  2. You get a proposal with the calculation in it

    Not only what it costs, but why this size and not a larger one. And if the outcome is that it will not pay for itself, that is in there too.

  3. We install and connect

    Including the cabling, the circuit, the earthing and the handover. On larger installations also the permit application and the arrangements with the netbeheerder, the regional grid operator.

  4. You see whether it does what it promised

    An installation with the wrong settings runs for months without anyone noticing: everything works, only the saving never arrives. That is why we measure afterwards.

Frequently asked questions


Why are there no prices on this site?

Because for nearly every product your own situation decides the price. For a charge point it is the distance from the meter cupboard to the car, for a battery the size of your peak. An amount that turns out to be wrong costs you more than no amount at all.

Can I have a charge point if I live in a flat?

Usually yes. The hold-up is rarely the technology; it is the decision of the VvE, the Dutch owners association that runs the building. We supply a worked-out proposal that can be put to a meeting.

My netbeheerder says a heavier connection is not possible. What now?

Then there are four routes: share out the capacity you have, buffer it with a battery, shift consumption in time, or share capacity with neighbours on the site. Which one fits follows from a measurement. That is worked out under grid congestion.

Do you advise without installing?

Yes. A month of measuring plus a report on what came out of it can be bought on its own. Sometimes the outcome is that nothing is needed and that moving one process solves the problem.
