Function
The hot water diverter feature page enables you to model savings and energy flows by diverting excess solar to the hot water system, using a diverter such as Catch Green, AC Thor, etc.
SolarPlus calculates how much excess solar energy is available for use by the hot water diverter, and optionally tops up / boosts from the grid on days when there is not enough sun.
When grid boost is selected, if the target kWh/day is not reached by solar by the time that the grid boost is available, (ie if it is cloudy, or the other loads are too high), then the remainder of the target kWh/day is drawn from the grid at the time you specify. Therefore, it is recommended to specify that grid boost starts in late afternoon or evening, or during off peak tariff times.
Current scenario
In this section, you can enter the details of the existing hot water energy consumption scenario. The details in this section need to specify the time at which the hot water system is currently operated.

Load and energy
...
Enter the maximum capacity of the load in kW and the average energy consumed by the load per day in both the current and the proposed scenario.
...
If you are swapping the hot water element, then put the new element size in the Proposal Load Scenario.
As a guide for how much energy is used for hot water in a home:
Low = 4kWh/day
Average = 6kWh/day
High = 10kWh/day
Very High = 20kWh/day

If “In addition to load profile” is not checked, make sure there is enough power in the consumption profile, as the load will activate only when the power is equal to or greater than the kW power value set in this section. If you are comparing a quote without a Smart Energy profile with a system Profile to one that has a Smart Energy profile, make sure that the energy consumption on both are the same. |
