Dry-Contact switch Installation Guide
Overview
The SolarEdge Smart Energy Management solutions allow increasing the self-consumption of a site. One
method used for this purpose is controlling the usage (consumption) of loads using Device Control
products.
The SolarEdge Device Control units divert power to an appliance (load) according to pre-configured
schedules, using the following modes:
Refer to
for examples of the device modes of operation.
You can re-configure the schedules at any time and manually switch appliances on and off.
You can configure the Device Control products locally through the SolarEdge inverter or remotely, via
the SolarEdge monitoring portal.
The SolarEdge Dry-Contact switch (referred to as "the device") is a ZigBee wireless load management
device. It switches loads (e.g. a heat pump) on and off according to system configuration. It can function
as an AC switch or as a control signal to indicate when the PV system is producing excess energy. It
supports a wide input voltage range of up to 250V and a wide input current range of up to 13A.

The device (typically a boiler or water pump) is controlled automatically to maximize self-
consumption. Grid power is used only if PV power is insufficient to meet the user’s “ready by” time. For
example, to heat water for 2 hours and have hot water by 18:00, set Total Time to 2 hours and Ready by to
18:00. The boiler may work before 16:00 if there is available PV power, but in any case you are guaranteed
to have hot water by 18:00
