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:
l
Schedule - TThe device turns on and off at times set by the user for the user’s convenience, regardless of
available PV power.w
Smart Save - The device (typically a boiler or water pump) is controlled automatically to maximize selfconsumption. 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
The boiler may work before 16:00 if there is available PV power, but in any case you are guaranteed to .18:00
have hot water by 18:00.w
Refer to Figure 2 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 AC Switch with meter (referred to as "the device") is a ZigBee wireless AC switch with a builtin energy and power-consumption meter that provides power measurements up to 2.5kW. Based on
these measurements and on the system configuration it switches the loads on and off.

Installation
The following figure illustrates a typical example of device operation with Smart Save and Schedule
modes. Note that in Smart Save mode, the consumption is reduced by taking advantage of excess PV
earlier in the day.
Figure 2: Examples of device operation
To enable the AC Switch functionality, the following supporting devices must be installed:
l
Device Control ZigBee Module, installed inside the inverter. For physical installation refer to

l
Do not connect loads that require a continuous current supply (e.g. fridge, freezer).
l
Do not use the product if it is damaged or malfunctioning.
l
Never connect loads that can cause injuries or fire if they are switched on unintentionally
(e.g. an iron).
l
Do not let the product come into contact with water or other liquids.

The enclosed documentation is an integral part of this product. Keep the documentation
in a convenient place for future reference and observe all instructions contained therein.
1. Release the two screws of the device front cover and remove the cover.
2. Position the device against the wall and mark the drilling hole locations, at a maximum distance of 50
m from the inverter. Do not use the device as a drilling template as it may damage the enclosure.
3. Drill the holes and mount the device using screws and nuts. Fasten the unit to the wall.
4. Release the three internal screws at the bottom of the device, and remove the cable bracket.
Figure 4: AC Switch connections
5. Connect the load wires to the terminal blocks (see Figure 4, and Figure 5).

Manual - turns the device to ON or OFF, as described below
Auto - allows setting two types of schedules for device control, as described in the next sections:
o Smart Save - set the device operation requirements (ready-by and duration values). This mode
is useful for maximizing self-consumption using excess PV power: the device operates
autonomously based on configured settings.
o Schedule - set the device start and stop times regardless of available excess PV power.
To set Manual mode:
1. Select Mode è Manual

Load Rating - the appliance rated power (in kW)
Export TH (threshold) - optional; the minimum power (in W) above which the excess PV power
will be diverted to the appliance. This value can be lower than the load rating. The default value is
5% above the Load Rating.
Import TH (threshold) - optional; the maximum power (in W) purchased from the grid and
diverted to the appliance. The default value is 5% of the Load Rating.
NOTE
If changing the Export TH and Import TH default values, make sure they sum up to a
value that equals or greater than the appliance Load Rating value. Otherwise, the
device will turn off when there is insufficient power to divert to the appliance.
Min ON Time - (optional); the minimum duration (in minutes) the appliance should remain
ON once switched on, even when no excess PV power is available. The default value is 1 minute.

If the value of Max Duration is longer than the value of Duration, the device will use up only
excess PV energy in the difference time. For example, if Max Duration = T1 and Duration =
T2, during (T1-T2) only excess PV power will be used.
