How can I charge my E3/DC battery automatically at the cheapest times with Ostrom?

Thanks to our partnership with E3/DC, your battery can automatically charge during the cheapest hours – using Ostrom’s SimplyDynamic tariff and the Dynamic Pricing feature available in the E3/DC intranet.

To use Dynamic Pricing with your E3/DC system, you’ll need:

As an E3/DC customer, you’re eligible for a free smart meter when signing up for the SimplyFair tariff.

👉 To claim it, just contact our support team for your referral code and enter it in the signup form.

Already an Ostrom customer?
Send us your contract ID, and we’ll add the referral code to your account.

First, we’ll check if we already cooperate with your grid operator: Check the map of our partner grids

​✅ If we do:
We’ll send your order directly to the grid operator. They’ll contact you to schedule the installation.

⏳​If we don’t (yet):
We’ll add you to our waiting list and let you know as soon as we can move forward.

The smart meter installation and tariff switch usually take at least 12 weeks. If we're adding a referral code to an existing account, the process may take at least 16 weeks.

Once your new smart meter is installed, your grid operator will notify us about the meter change. As soon as we receive your live consumption data, we'll switch your tariff to SimplyDynamic.

You can then activate Dynamic Pricing in the E3/DC intranet to charge your battery automatically during the cheapest hours. 📄 Click here for the step-by-step guide

💡 Good to know:
E3/DC devices aren’t yet compatible with the Ostrom app, so you won’t be able to control your battery directly through it.

SimplyDynamic is fully integrated with E3/DC. Please use their intranet to manage and activate Dynamic Pricing for your battery.
