Greetings all, a question came up for me this morning looking over an Enphase Ensemble thats about to be installed.
Its a residential 200A service, typical all electric house for the Pacific NW, with resistance electric heating.
The Ensembles ATS will be connected just after the main service disconnect and supply the main house panel.
(The service disconnect will remain due to space constraints)
There is no proposed sub panel for backed up loads.
Similar to a whole house generator automatic transfer switch.
However a typical ATS will have some load management contactors that the Ensemble does not have.
So the question arises how do Energy Storage Systems comply with Article 702(B)(2)?
Does the inverter just sense if a load is too much and shut off?
Thanks in advance

To answer my own question article 702 does not apply article 710 does, specifically 710.15
