Load shed for 60A chargers on small panels

[rwojo]

I use the SAK-60 from PSP to load shed my 60A circuits so that they don't run on the generator. Standard load shed modules from Kohler (what I have) or Generac only handly 50A.

Anyway, I was placing a new order and noticed they have a new product called the SAK-60MS. It's very similar to the SAK-60 but instead of detecting a generator waveform, it uses CTs installed on your main panel (or subpanel) to disable the load if your panel is crossing a certain threshold.

So that's pretty cool and I think would help out the EV community that is looking for a way to add a large circuit to charge cars, but would otherwise fail a load calculation on their panel which may be smaller (e.g., 100A). If you have an all electric home this could even impact you on a 200A panel.

You can read up on it here: Wireless load dropping and load management for electric vehicles. Not sure where this can be ordered right now or even if it is out already, but I have ordered the standard SAK-60 from Kodiak Power Solutions (talk to Michael) and I'm sure he can get them if they are available.

HTH someone!

The standard sak-60 is $240 online, so this EV version probably isn’t that much more. Neat product.

I actually just ordered another SAK-60 today for my new circuit, and it was $149 before tax/shipping. Not too bad: Universal 60 AMP Wireless Generator Load Drop & Load Manage Relay

Did you pick up the SAK-60MS?

My electrician friend recommended it for me as well.

I'm using the standard SAK-60 modules to shed on generator only, I don't have the SAK-60MS.

That said the SAK-60 has performed great for me and these units are very similar. PSP did just recently raise prices, but I recommend calling Michael there and they may even be able to do a discount (mention Robert from Atlanta).
