Smart AC wallbox

ChargeFlow

A 7, 11 or 22 kW wallbox that charges your car from your own roof. With the EnergyPilot local controller it follows the solar surplus through the day and keeps the home under the main-fuse limit.

Highlights

Part of a small home energy system.

  • Solar surplus charging

    Charging power follows the surplus — no grid energy in Solar Only.

  • Dynamic load balancing

    Backs off when the oven or heat pump starts, then rises again.

  • Battery Boost

    Adds PowerCube or SolarHub power on a small supply.

  • Local app control

    Start, stop and set the current on site — even without internet.

Smart charging needs the EnergyPilot local controller (VDG-EM-1 or VDG-EM-3) at the grid connection; one EnergyPilot controls one charger. Battery Boost also needs PowerCube or SolarHub storage.

Charging that follows the sun

More of your own solar in the car.

EnergyPilot measures solar, home load and grid power at the grid connection and sets the charging current continuously. Charging starts or stops only after conditions have been stable for 30 seconds, so a passing cloud does not interrupt it.

The car charges only from surplus solar. Charging starts once the surplus covers the 6 A minimum (about 1.4 kW single-phase) and pauses when the sun drops.

Illustrative single-phase example for a small home system with a 7 kW wallbox. Actual values depend on the system, the weather and the vehicle.

Charging modes

Six ways to charge, chosen in the app.

01

Manual

Fixed or maximum power set by you. The fastest charge.

02

Solar Only

Charges only from surplus and pauses when the sun drops. No grid energy.

03

Solar Priority

Holds the 6 A minimum with a small top-up, then shifts to solar as it rises.

04

Battery Boost

Adds storage power and stops at a set battery level: 20, 30 or 50%.

05

Schedule

Time windows with a power target and a battery state-of-charge target.

06

AI

Uses dynamic tariffs, weather forecast and driving habits to plan charging.

Modes are those shown in the VIP Cloud app and may be refined with software updates. Available functions depend on the market.

Local mode

Control it on site, online or not.

In local mode the VIP Cloud app connects straight to the wallbox. Start and stop charging, change the current and check the session on site — without the internet. Online, VIP Cloud adds remote access, history and OCPP connection to charging-management platforms.

  • Set-up over Bluetooth and Wi-Fi in the VIP Cloud app
  • Start automatically on plug-in, from the app or over Bluetooth; RFID card on request
  • LED light bar shows the charging status

  1. Installation by a qualified electrician on a dedicated circuit with the protective devices required by local wiring rules.
  2. The minimum charging current is 6 A per phase, about 1.4 kW single-phase or 4.1 kW three-phase. Some older vehicles do not accept current adjustment.

A single plug-in unit up to 800 W (such as SolarCore VM800WE-P2 or SolarKit) and PowerCube VA800D may be connected by the owner where local rules allow; where national rules permit higher plug-in limits, SolarCore P4 can also be connected by plug. Other SolarCore systems on an AC trunk cable, PowerCube VA2000D and above, VB5000D packs, SolarHub, ChargeFlow and EnergyPilot are installed by a qualified electrician.
