SolarEdge Dry-Contact switch Bedienungsanleitung

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 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 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.

SolarEdge-Dry-Contact switch Installation Guide

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

lSmart Save - 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.w

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 Dry-Contact switch functionality, the following supporting devices must be installed:

lDevice Control ZigBee Module, installed inside the inverter. For physical installation refer to

Installation

CAUTION!

lThis product must be operated under the specified operating specifications, as described in

the latest technical specification datasheet.

lConfigure the product so that the load connected is not switched on or off more

frequently than specified by the load manufacturer.

lDo not connect loads that require a continuous current supply (e.g. fridge, freezer).

lDo not use the product if it is damaged or malfunctioning.

lNever connect loads that can cause injuries or fire if they are switched on unintentionally

(e.g. an iron).

lDo not let the product come into contact with water or other liquids.

lThe 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.e

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.

5. Connect the load wires to the terminal blocks (see Figure 4, Figure 5 and Figure 6 ):w

l230 Vac (connections 1,2 ) - to Line and Neutral. The connections are interchangeable.

lDry-contact 250V / 13A maximum (connections 3, 5) - to a dedicated voltage source from the

appliance (see Figure 3), or an external power supply according to the input control specifications

of the appliance (see Figure 4).

lManaged load (connections 4,6) -to the appliance input control

The two switches have a single control. That is, either both are closed or both are opened.

lLoad Rating - the appliance rated power (in kW)

lExport 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.

lImport 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.

l 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.e

oReady by - requested energy must be diverted to the load by this time (default: 00:00;

format:hours:minutes).

oDuration - minimum accumulated time the load must remain on (in minutes; default: 00).

oMax Duration - maximum accumulated time the load can be on throughout the day (in

minutes; default: 00).

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.

oWeek Days (optional) - days to repeat the settings (default: every day).

Week Days <1234567>

oStart/Stop Time - the time of day by which the Dry-Contact switch must start/complete

its task of delivering energy to the load (default: 00:00; format:hours:minutes). If these

values are not set, only the excess PV power is used.

oWeek Days (optional) - days to repeat the settings (default: every day).

NOTE

In Auto mode , if you configure overlapping time-frames between Schedule and Smart Save

options, Schedule mode takes precedence over the Smart Save mode.
