I would like to monitor both the power I am using from the electric company, but also my usage when I have to flip over to my 10kW generator. I want the generator monitor so I can easily see how much generator capacity I am using at a given time, to avoid maxing it out and conserving precious gas (my town had been out for weeks at a time in the past!).
I’m having a hard time figuring out exactly how this monitor’s clamps connect to know if it would work for both. From what I can tell, one clamp needs to go on each of the legs of the incoming power, correct? My generator will feed in via a special breaker, protected by an interlock kit, attached to my generator, meaning when the generator is running the show, the main line in to the panel will not be energized, so the HEM connected to the main line will not get a reading.
Assuming I understand the clamp install setup correctly, I am thinking I have two options. Either a) I get a second HEM and install it on the lines feeding this generator breaker, having both meters connected to ST, or b) get an additional set of clamps, and manually switch which are hooked to the meter when I switch power. If I need a second monitor, I’m thinking of a v1 battery powered for that end - since it will only be used during the hopefully rare times I am on generator power, I am not worried about chewing through batteries, and it is also half the cost of the v2.
Does anyone know the differences between the v1 and v2? Are the clamps interchangeable?
Do I understand things correctly here, or am I way off?
