Function
The load shifting page feature enables you to model savings and energy flows from changing the moving a load from a fixed time, to being controlled by either:
a programmable contactor that turns the load on when there is enough excess solar available to supply the load
...
Eg ‘Catch Control’ or Fronius Ohm Pilot
a timer
Eg a timer on a hot water heater or pool pump that normally runs at nig
Current load scenario
In this section, you can On the left, enter the details of the existing load scenario which you want to shift. The details in this section need to specify the timing in which the load is currently operated.
Proposed load scenario
In this section, you can enter the details of the proposed load scenario. The details in this section need to specify the proposed time for the load shifting to occur and the load details.
Time ranges
The time ranges can be entered at an hourly level on the 24-hour clock. To specify multiple ranges for the same weekday, click on “+Weekly Range”.
Click on the “Copy weekday to weekend” button to copy the same ranges from the weekday to the weekend.
...
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.
...
Price basis
The options available to select are:, including:
When the load runs
Load power rating
Maximum energy used per day
Price basis
Regular tariff rate - this will use the grid tariff that is applicable at that time, whether it be a flat rate, or Time of Use rate, as specified on the Energy page.
Controlled load rate - this will use the controlled load tariff as specified on the Energy page. This applies to loads such as controlled load hot water and underfloor heating.
...
In addition to load profile?
Click on the “In addition to load profile” checkbox if the load details mentioned are not a part of the consumption profile loaded on the Energy page.
...
| Info |
|---|
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. |
Proposed load scenario
In this section, you can enter the details of the proposed load scenario.
when the load will run (if on a programmable contactor that uses excess solar, then make this time range 6am to 8pm)
Load power (this may be different than the load power of the current scenario). Eg if you swap the element in the hot water tank, specify the size of the new element)
Max energy per day (how much energy is required by the load)
Whether the load is controlled by a timer, turns on when there is sufficient solar, or turns on when there is sufficient solar, and the battery is full.
Time ranges
The time ranges can be entered at an hourly level on the 24-hour clock. To specify multiple ranges for the same weekday, click on “+Weekly Range”.
Click on the “Copy weekday to weekend” button to copy the same ranges from the weekday to the weekend.
