Smart Energy Hot Water Installation
Overview
The SolarEdge Smart Energy solutions allow increasing the self-consumption of a site.
One method used for this purpose is controlling the usage (consumption) of loads
using Smart Energy products.
The Smart Energy devices divert power to an appliance (load) according to pre-
configured schedules, using the following modes:
Schedule - The device turns on and off at times set by the user for the user’s
convenience, regardless of available PV power.
Smart 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 the Duration 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.
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 Smart Energy products locally through the inverter, or remotely
via the monitoring platform (or monitoring smartphone app).
The Smart Energy Hot Water (referred to as "the device" throughout) is a Smart Energy
product that diverts excess energy produced by the PV system to a load, normally a hot
water heater. The device saves energy and reduces utility bills by storing energy as hot
water during the day when surplus energy is high, and providing free hot water later on
in the day.
