go-e controller for dynamic load management and PV surplus charging Control 1- and 3-phase

With the go-e Controller (MPN: CH-30-01), you can charge your electric car or plug-in hybrid even more cost-effectively and safely when used in combination with a go-e Charger. You maximize the use of your excess PV power by feeding it directly into the wallbox. This way, you increase your self-consumption and get the most out of your PV system. Dynamic load management ensures that your home electrical connection isn’t overloaded. When load peaks are detected, it automatically adjusts the charging power for the electric cars and plug-in hybrids connected to the charging stations and increases it again as soon as possible. It is compatible with all go-e wallboxes (Gemini, Gemini 2.0, PRO, and HOME series), all PV inverters, and AC battery storage systems. The controller supports both single-phase and three-phase connections. Plus, you can easily and conveniently control and monitor all parameters via the app.

Monitoring and Control

With the controller, you have full control over the energy flows in your building. This allows you to control the charging of your electric car in conjunction with go-e wallboxes based on the sun’s position and current electricity demand. You can also use it to monitor other household appliances such as heat pumps, air conditioners, or saunas, ensuring you always have a clear overview. It is suitable for both single-phase and three-phase operation. In three-phase power grids, you can monitor three additional devices, such as PV inverters, AC battery storage systems, and heat pumps. In single-phase power grids, you can monitor up to five additional devices. This makes your energy management simple and smart.

Optimize Your Self-Consumption

Use excess solar energy to efficiently charge the batteries of your electric vehicles via one or more chargers. When your PV system produces more energy than your household appliances need, this smart charging method allows you to maximize your self-consumption. No special measurement of PV production is required for PV surplus charging or dynamic load management. Self-consumption is accurately displayed via direct measurement at the inverter’s AC connection. Direct communication with the PV system is not necessary. If you have a battery storage system, it is also taken into account, provided it can be measured at the AC connection. However, with hybrid inverters featuring a DC battery connection, direct measurement of battery power is not possible.

Automatic Phase Switching

As soon as your PV system generates at least 1.4 kW of surplus energy, the controller sends this information to the go-e Charger, which then takes over the charging process using the surplus PV power. It automatically switches between single-phase and three-phase charging, depending on how much power is available. This allows you to maximize your self-consumption even when PV production is low. As soon as your PV system generates enough surplus energy, the controller seamlessly switches to three-phase charging.

Dynamic Load Management

To prevent power outages, a reliable load management system is essential when charging electric vehicles. The charging stations already feature static load management, which takes into account the maximum available power in your building when multiple electric vehicles are charging simultaneously. However, you’ll need to allow for a buffer to accommodate other power consumers in your household. The go-e controller offers you an even smarter solution with dynamic load management. It automatically adjusts the charging power of the connected wallboxes when many electrical appliances are active at the same time. This ensures that your household appliances and charging stations never consume more power than your home’s electrical connection can handle—and it all happens completely automatically.

Control everything conveniently via the app

Configure your solar energy settings conveniently from the comfort of your couch using the go-e app. With the app, you have access to all of the controller’s settings and can customize them to suit your needs—whether for dynamic load management or managing electricity consumption in your building. This way, you always have everything in view and under control. Once the controller is connected via Wi-Fi or LAN, charging your electric vehicle becomes even easier, safer, and more cost-effective.

Expert or highly experienced?

Do you have programming skills? Then enjoy even more control when charging your electric vehicle! The controller offers additional interfaces such as a local HTTP API, Modbus TCP, and MQTT. With the optional cloud connection, you can further optimize the controller’s functions and customize them to your individual needs.
