Which demand charge controller (DCC) model do I need ?

We have adapted the demand charge controller (DCC) to be a good fit for every type of building complexity, but how to know which of the 4 base models to choose from? Luckily, most situations fall into two contexts.
The multi-unit building context
Multi-unit residential buildings (condos or apartments) or townhouses whose electricity meters are located at an appropriate, unobstructed distance from the electrical panel (also known as accessible meters).
DCC-9, if your electrical panel is between 60A and 125A: an electrician would insert the DCC-9 between the meter stack and your electric distribution panel electrical panel.
DCC-11, if your electrical panel is between 150A and 200A: an electrician would insert the DCC-11 between the meter stack and your electrical panel.
The single-family home context
Homes or townhouses that have an electrical service panel in an accessible location and without capacity for the addition of electric vehicle charging equipment.
DCC-10, used less than 5% of the time: an electrician would add a new branch from your electrical panel to the DCC-10, then to the EV charger.
DCC-12, used more than 95% of the time: an electrician would add a new branch from your electrical panel to the DCC-12, then to the EV charger. The DCC-12 doesn’t include an internal breaker, which is not often required since you already have one in your electrical panel. This makes the DCC-12 model a smaller size and less expensive.
Also offered: DCC models in BOX form
A DCC-BOX is the enclosure for the DCC-PCB technology that powers the DCC. We sell the BOX as an option because we realized that adding infrastructure can be costly and that the DCC-BOX alone is a commitment to the space and wiring needed to make a building ready for the installation of EVs. When a charging station request is made, the DCC-PCB technology can be ordered so as to lump the cost for the new EV owner, without creating a cost for additional infrastructure or other MURB residents. The DCC-9 is also offered grouped in arrangements of 3 or 6 to optimize on available electrical room space and according to need.
