Users who create models with both AC and DC loads or deferrable loads, such as pumping or HVAC, can use the Advanced Load module. The Advanced Load module consists of a second Electric load and the Deferrable load.
To access the Advanced Load options, use the Electric #2 and Deferrable buttons under the Load tab at the top of the page. The Electric #2 page is the same as the Electric #1 page, described in the Electric Load section of the help.
Deferrable loads are loads that require a certain amount of energy, but can wait until power is available instead of needing it at any given moment.
