EMS Integration

How DC chargers connect with PV, BESS and EMS systems

For DC charging projects, PV compatibility is handled at station level. EN Plus DC chargers can be integrated into PV + BESS charging projects through Modbus TCP EMS connection and charging management platform support.

☀️

PV generation

Solar power is monitored by the EMS and can be used directly or stored through the site energy system.

🔋

Battery storage

BESS stores surplus solar energy or low-cost grid energy to support faster charging during peak demand.

DC fast charging

Mobox, Turbo and Rocket act as charging terminals while EMS manages station-level power allocation through Modbus TCP.

Modbus TCP for EMS, platform support for charging operation

EMS coordinates site energy through Modbus TCP, while the charging management platform supports charger monitoring, charging sessions, remote operation and project-level visibility.

Charging Modes

Solar charging modes on supported configurations

ECO, MIX and BOOST modes are available on supported configurations such as Caro Plus. For other products, PV and EMS support should be confirmed by project configuration.

☀️

ECO Mode

Use available solar energy for green-priority charging when PV production is sufficient.

MIX Mode

Use solar energy first and let the grid supply the remaining power when PV output is not enough.

🚗

BOOST Mode

Prioritise charging speed when faster charging is required while keeping smart energy control available.

Load Balancing Options

Protect home power while using more solar energy

Balance EV charging with household loads, solar production and home power limits through smart meter connection and residential load balancing.

LBC Reader P1 / HAN for European homes

A plug-and-play residential load balancing controller for homes equipped with P1 or HAN smart meters.

  • Designed for villa and house scenarios
  • RJ12 P1 or RJ45 HAN smart meter connection
  • PV surplus charging, ECO Mode and MIX Mode
  • Up to 5 chargers managed in cloud control
  • Magnet installation and reduced additional wiring

Residential load balancing for solar homes

Home energy control for PV charging, household load protection and smarter residential charging schedules.

  • Dynamic load balancing between EV charging and household loads
  • Solar priority and smart meter integration
  • Home power protection and peak demand control
  • Support for home and small residential charging setups
  • Charging current adjustment based on household demand and available solar power
Quick Selection

Match AC home charging and DC project charging with the right energy-control path

Use residential smart meter and load-balancing paths for AC wallboxes, and use Modbus TCP EMS integration for DC PV + BESS fast-charging projects.
