Re: Charging issue, electric panel is full, Load miser or $$$

The best $5k (CDN) solution, IMO, is replacing the resistance-only heat with a new, high EER heat pump. It will both free up enough power for the car in all but the most frigid weather, and save money over its lifetime.

Thanks for the reply! To address the heating, here's how it shakes out on my property:
Principal House
-- Fully variable DC-compressor based heat pump with gas furnace backup
-- electric baseboard in the suite (building code requirement)

Coach House
-- Super-insulated building conforming to Passive House standards
-- heating load is a 1 kW baseboard only

I've shed all the loads I can, heating or otherwise. And it's not in the budget to go to a 400 amp service, for a number of reasons.

Hi There,

I've recently found a marvel, the DCC. It's a demand charge controller for an electric vehicle enabling the installation of the EV charger when load calculation is max out.

It works like a loadmiser, but instead, it is directly installed on the main power source of the house with a 40amps feeder going to the DCC. The CT's (installed on main power source) read the demand for the controller and it automatically stops the charging if 80% of the main breaker capacity is reached. After 15 minutes under 80%, the EV charger is re-energized automatically.

Only in french for documentations, but it is approved CSA US for installation across north America.

Do you use the electric baseboards? If not, I'd suggest using the load splitter with them instead of the dryer.

Baseboards are the only heat source in the basement suite; the tenant might be a bit peeved if I mess with that! Besides, they're all on their own circuits, so adding a miser to that would be... miserable.

I've reached out to the DCC supplier, waiting to see if their product is the silver bullet I'm looking for. Super interesting; thanks for sharing!

Will report back.

Thanks for this as well! In essence, this is a load miser, though it appears they've updated the technology (from when it was initially used in the 1940's/1950's) to include an optional J1772 connector.

Unfortunately, I'm not seeing any CSA/UL certifications listed on the site, which makes me a bit leery of the product.

FWIW, the OberCharger has built-in GFCI protection with hardware breaker. It's a German designed product, but it appears to be assembled and sold in the US out of their office in Portland, OR so shipping is free in the US.

I've never seen nor used it, so I'm not really endorsing it - just thought I'd mention it as it seems like a good fit for your situation.

If you not an electric house than 100A is fine. In my area you must upgrade to a 200A panel. That usually gives you more slots. My Eaton panel allows for half slot breakers to increase the breakers available. My standby current is about 600W and that includes the DVR. I have lots of room.
