Dry-Cntact switch Installatin Guide Overview The SlarEdge Smart Energy Management slutins allw increasing the self-cnsumptin f a site. One methd used fr this purpse is cntrlling the usage (cnsumptin) f lads using Device Cntrl prducts. The SlarEdge Device Cntrl units divert pwer t an appliance (lad) accrding t pre-cnfigured schedules, using the fllwing mdes: Refer t Figure 2 fr examples f the device mdes f peratin. Dry-Cntact switch Installatin Guide Schedule - TThe device turns n and ff at times set by the user fr the user s cnvenience, regardless f available PV pwer.w Smart Save - The device (typically a biler r water pump) is cntrlled autmatically t maximize selfcnsumptin. Grid pwer is used nly if PV pwer is insufficient t meet the user s ready by time. Fr example, t heat water fr 2 hurs and have ht water by 18:00, set Ttal Time t 2 hurs and Ready by t 18:00. The biler may wrk befre 16:00 if there is available PV pwer, but in any case yu are guaranteed t have ht water by 18:00.w Yu can re-cnfigure the schedules at any time and manually switch appliances n and ff. Yu can cnfigure the Device Cntrl prducts lcally thrugh the SlarEdge inverter r remtely, via the SlarEdge mnitring prtal. The SlarEdge Dry-Cntact switch (referred t as "the device") is a ZigBee wireless lad management device. It switches lads (e.g. a heat pump) n and ff accrding t system cnfiguratin. It can functin as an AC switch r as a cntrl signal t indicate when the PV system is prducing excess energy. It supprts a wide input vltage range f up t 250V and a wide input current range f up t 13A.

Installatin The fllwing figure illustrates a typical example f device peratin with Smart Save and Schedule mdes. Nte that in Smart Save mde, the cnsumptin is reduced by taking advantage f excess PV earlier in the day.
