Zaptec Sense 65 A – dynamic load management for Zaptec chargers

Zaptec Sense is the load management for your Zaptec charger. In the meter cabinet, Sense continuously measures the building's consumption and adjusts the charging power of your Zaptec Go, Go 2 or Pro accordingly: when the house uses little, the car charges faster; when consumption rises, charging power is reduced. This way you make full use of the available power without overloading the house connection or tripping a fuse. The charger does not have to be permanently throttled.

This bundle includes the 3-phase direct-connected meter up to 65 A – no current transformers needed. It is suitable for most single-family homes and smaller buildings and is also intended as a retrofit for an existing Zaptec charger.

Right for you if …

• your house connection is limited and you still want to charge at full power,
• you already have a Zaptec charger or are buying one now,
• your main fuse is 65 A or less.

Not ideal if …

• your house connection is above 65 A – then you need Zaptec Sense 150 A or 600 A with current transformers, just ask us,
• you have a charger from another manufacturer – Sense only works with Zaptec,
• you want to charge with PV surplus in Austria – Zaptec does not offer this feature here yet,
• you are ordering for a company, municipality or organisation – then our B2B shop shop.ampion.at is the right place.

What it does

• No overload: Charging power continuously follows the actual consumption in the building, keeping the main fuse protected.
• Avoid peaks: In the Zaptec app you set a consumption limit, for example to stay below expensive power peaks.
• Live data: You see household consumption, available current and status in the Zaptec app or the Zaptec portal.
• Ripple control signal: A potential-free contact on the meter can integrate the grid operator's signal.

Good to know

• Internet required: Sense sends the readings to the Zaptec Cloud via Wi-Fi (2.4 GHz only) or Ethernet. Without a connection, the charger only charges at the configured minimum current.
• Germany (§14a EnWG): Via the ripple control contact, the grid operator can reduce the charging power.
• PV surplus: Zaptec currently offers this in Germany, the Netherlands, Belgium, Switzerland and Luxembourg, starting with selected home installations on TN grids. Austria is not yet included.
• Installation: Your electrician handles mounting and wiring. Sense is set up via QR code and Bluetooth in the Zaptec app.
• Cheaper as a set: For Zaptec Go 2 and Zaptec Pro M&E, Sense 65 A is also available as a PV set together with the charger.

Frequently asked questions

Does Sense work with my charger?

Yes, with Zaptec Go, Go 2 and Pro. Chargers from other manufacturers are not supported.

Is the meter included?

Yes. The bundle includes the Carlo Gavazzi EM340 3-phase direct-connected meter up to 65 A and the 5 V power supply. You do not need current transformers.

Which Sense version do I need?

Up to a 65 A main fuse, this inline version is enough. Above that you need Sense 150 A or 600 A with current transformers.

Where is Sense installed?

The meter and power supply go into the meter cabinet or distribution board; Sense itself sits in or on the cabinet, indoors only. Your electrician takes care of it.

What happens without internet?

If Sense loses its connection to the Zaptec Cloud, the charger only charges at the configured minimum current, so no fuse trips.

Can I charge with PV surplus using Sense?

Not in Austria at the moment. Zaptec currently offers the feature in Germany, the Netherlands, Belgium, Switzerland and Luxembourg, starting with selected home installations on TN grids.
