Question: What's the best way to wire the CSP in the garage? Hard wired and with 100A circuit to maintain a constant load of 80A? Is that possible? OR do I have to do something else...like 60A circuit for 48A charging OR 50A circuit with an installed NEMA 14-50 Receptacle for 40A charging?

My specific situation and any help would be appreciated here...I am getting solar installed and they are going to re-do some of my electrical.

My current breaker at our power meter is 50. The electricities for the solar company is going to upgrade that to a 100 breaker. The power meter currently has a rating of 120 a max, so I am assuming the 100 breaker is the highest without doing any trenching or anything major. And from what I hear that is good enough for what I need for solar and EV charging.

My house electrical panel (in bedroom) has two extra slots, so we are going to add a sub panel (in the garage) for the solar panels (about 5.5 KW) and the CSP.

You definitely need a knowledgeable electrician to do this for you. I had 200AMP service at my house and upgraded to 400AMP so that I could use the FCSP to its max potential which requires a dedicated 100AMP circuit. It sounds like your panel is only being upgraded to 100 so you will not be able to get the maximum potential. At least, that is what this layman believes. Consult with an electrician and make sure they get your the max you can without tripping your whole panel when you start to charge your truck.

Yes, your best bet is a 100A circuit for the 80A CSP, as I just answered in the other thread.

No need to post the question in two different threads.

Thanks! Is that doable on a 100amp breaker.

Only if you have enough capacity remaining in your current service. It sounds like you live in a older home that has existed with a small service panel and predominantly gas appliances. You need a good electrician to give advice. You won't be able to add a 100A breaker to a 100A service panel for 80A charging. When an electrician calculates your capacity for expansion, I would shoot for a 60A circuit for 48A charging. If you must size it to 50A for 40A charging, be aware that the Charge Station Pro is rated for hard-wired installation only. AFAIK, there is no cordset supplied with it. So, the NEMA 14-50R will only be useful for 30A charging using the Ford mobile connector, or 40A if you purchase of an EVSE with a rated NEMA 14-50 plug and cordset.

Thanks for responding. The service panel is rated up to 125, and my neighbors added a 100 breaker, which is the same older set up I have, so I assume that is what is most likely possible? Would that be capable of adding a 100A sub panel panel for 80A charging? if not, then I guess I'd have to go with 60A circuit for 48A charging?

There are so many variables that it's impossible to answer your questions. It depends on the loads your house has currently. An electrician can calculate the maximum size of a circuit you can install.

Here's product that would solve your problem if your service panel is undersized to add a 100A circuit, and if the utility will allow it. It's a new product using an old method that takes the heavy EVSE load from the meter base ahead of your house panel without modifying it:

Wow, that is really interesting. Thank you!
