I've searched through most of the forum and I see there a bunch of you smart folks out there who have successfully got the HIS running and their trucks powering the homes, but I'm still scratching my head. I've looked through all the SunRun SOPs that Ford now links to, and sadly when we built our house, we didn't run conduit for the DC and Cat-6 wires. Before I dive in and tear holes in my walls, I have a few "dummy" questions on these wiring diagrams. (To be clear, I will have a electrician do this, but I just like knowing what's what.)
From what I can tell in manuals and wiring diagrams, in addition to the 100A wire from my breaker box for the charger (which is working fine), I need an 8 AWG 600V DC wire run and a Cat-6. There also appears to be a 14 AWG pair that runs to the EVSE that acts as a trigger to the charger somehow. What I don't know is what wires are powering my house when the power goes out.
My understanding is that the round portion of the charger head on the Charger Pro is AC and the bottom oval is DC for fast charging. At first I assumed that somehow the truck/charger converts the battery power to AC and feeds 120V back into the breaker panel (through the 100A breaker) onto the bus, but that doesn't sound right. The 8 AWG wire goes into an inverter which would convert DC to AC for the house, but is the whole house really being powered by an 8 AWG DC wire??? Based on a quick lookup on AWG - American Wire Gauge Current Ratings, a single core wire would only be able to supply 75 Amps, which at 600V would 45kw DC (right?). Is that what's really happening here?
The way the marketing material is presented, it makes it sound like I could run my "whole house" for three days. Realistically all I want to run is a refrigerator, my water pump, the boiler, network and computer gear, and maybe a freezer. According to our utilities folks, our average daily usage is 34 kwh so we should be good. I'd feel much better thinking that heavy, thick cord from the truck into the charger was going "straight" into the breaker box, but that puny 8 AWG wire? You run speakers with that! 😂
Smart folk, fill me and anyone else that might have similar questions in. Thanks in advance.
