The Pro 3EM Add-on is an accessory for the Shelly PRO 3EM-120A and Shelly Pro-400A consumption meters: a galvanically isolated module, with the help of which the PRO 3EM device can be switched potential-free, and it can also be used to connect an external contactor or other electrical device.

The Pro 3EM Add-on is a useful accessory for the Shelly PRO 3EM-120A and Shelly Pro-400A consumption meters: it is a galvanically isolated module, which enables the PRO 3EM device to be switched potential-free, and can also be used to connect an external contactor or other electrical device.

The PRO 3EM - unlike the 3EM, is not capable of controlling an external contactor or relay, but with this accessory we can make it capable.

This is also a device that can be fitted to the DIN rail of an electrical cabinet, we have to install it directly next to the PRO 3EM consumption meter and snap the two modules together.

Its power supply is provided by the Pro 3EM, we only need to connect the I / O (input / output) for switching, it can switch a maximum of 2A at a maximum of 240V AC or 30V DC.

Possible uses:

Keep track of how much energy the solar panels / wind turbines produce, and with the Shelly Pro 3EM accessory you can easily save money by controlling consumption. Connect the Shelly Pro Add-On to the devices to be controlled and use Shelly Pro 3EM's real-time information on how much energy you produce and consume. When you need to save energy, the Shelly Pro3EM Add-on can automatically turn off non-essential appliances.

For example, if a solar system is producing more energy than your home is consuming, the Shelly Pro 3EM Add-On can automatically activate consumers to use it. For example, you can set it to turn on the water heater, electric vehicle charging station, or other energy-intensive devices. This way, you can get the most out of the energy produced by your solar system, reduce your dependence on the grid and save money.

Shelly Pro 3EM, enhanced with a Shelly Pro 3EM accessory, can also offer weather-dependent energy optimization. With scripting, you can effectively control your devices based on the weather forecast. After receiving real-time weather updates, Shelly Pro 3EM takes the actions specified in the script. For example, if sunny weather is forecast, the Shelly Pro 3EM Add-On can automatically turn off the heat in anticipation of higher temperatures.
