In my experience, when you're dealing with a battery as huge as the Silverado's, safety has to come first or you're gonna end up with melted wires. I've tried many setups over the years, and honestly, jumping straight to 80 amps can be super risky if your home's electrical isn't basically perfect. For a safer, more reliable middle ground that still packs a punch, I really suggest the Wallbox Pulsar Plus 48 Amp Level 2 EV Charger. It's UL-listed and way more compact than those massive high-amp units, so it stays much cooler during those long overnight sessions.

Another solid, conservative option is the Emporia Level 2 EV Charger 48 Amp. It has great thermal management and let's you monitor everything from your phone so you can make sure nothing is overheating while you sleep.

- Hire a pro for the hardwire install!! Seriously, don't DIY this.
- Make sure they use heavy-duty 6AWG wire for a 48-amp load.
- If you're dead set on home backup, you really gotta look into the GM Energy V2H Enablement Kit specifically to pair with the truck's bidirectional tech.

Just be careful with those high-draw setups, i've seen some get SO hot it's scary. Better to charge at 11.5kW safely than push for 19kW and risk a fire lol. good luck!!

For your situation, basically you've gotta understand that the Silverado EV's massive 200+ kWh battery pack is a total beast to fill up. If you want the fastest home speeds, you need a unit that supports an 80-amp circuit to deliver 19.2 kW, which is exactly what the truck's onboard charger can handle. Most standard wall boxes only do 40 or 48 amps, which honestly feels like forever when youre trying to add 300+ miles of range overnight.

I personally went with the GM Ultium PowerUP+ Level 2 Charging Station 19.2kW and had it hardwired on a 100-amp breaker. It works flawlessly and I've had zero issues with overheating, even in my hot garage. If you want the bidirectional home backup features (V2H), you're actually gonna need more than just the charger—you'll eventually need the GM Energy V2H Enablement Kit which includes the inverter and dark start battery.

I looked at the ChargePoint Home Flex Level 2 EV Charger 50 Amp too, but it tops out at 50 amps (12 kW) even when hardwired, so you're leaving a lot of speed on the table. Basically, if you want the MAX speed the truck allows, stay with the official GM PowerUP+ hardware. It’s been super reliable for me and the integration with the app is actually decent. Good luck with the new rig, you’re gonna love it!! 👍

Like someone mentioned, the wiring for a 200kWh pack is no joke. I've done a few DIY installs and you really want something with solid thermal management because that truck is gonna be pulling high current for hours.

• Emporia Level 2 EV Charger 48 Amp: I love this for the data side of things. If you get their Vue monitor too, you can balance the load so you dont trip your main breaker if the AC kicks on while the truck is charging. It's very DIY friendly and the price is hard to beat.
• Autel MaxiCharger AC Wallbox Home 50A: This unit is built like a tank. The cooling fins on the back actually work, and I havent seen it throttle due to heat even in a garage thats 90+ degrees. It feels much more industrial than the plastic stuff. Honestly, if you want that bidirectional backup, you're pretty much locked into the GM ecosystem for now. Most third-party stuff wont talk to the Silverado's software for home power yet. Just make sure whatever you pick is hardwired with 6 AWG wire at a minimum to keep things cool... basically dont skimp on the copper.

Honestly, I have been on these forums forever but I am still basically a total newbie when it comes to the heavy duty electrical stuff for these trucks. That battery pack is just SO big that it feels like a whole different ball game than what I am used to. Before you pull the trigger on a unit, are you thinking about doing the wiring yourself or are you definitely getting a pro to come out? I have been looking into this a bit myself and here is what I think:

• Just get something from Emporia if you want to track all your stats
• Look at anything from Tesla because their stuff is surprisingly compatible with everything now
• Stick with a brand that has a really long track record even if they arent the cheapest It really depends on how much you want to mess with it yourself tbh. Are you planning on upgrading your main panel at the same time or are you trying to work with what you already have in there?

Seconding the recommendation above. Ngl, the 19.2 kW setup is the way to go, but I'm honestly a bit cautious about going that high for every charge. I had issues with my last high-amp install getting WAY too hot. If you want a solid alternative to the ChargePoint, maybe look at the Enel X Way JuiceBox 80 Amp Level 2 Smart EV Charging Station. It's a beast but it's pretty pricey and honestly, the app can be kinda buggy sometimes.

Just make sure your electrician checks your panel first cuz these trucks pull SO much power. It's kinda scary how fast they can drain a home grid lol. You'll definitely need the GM Energy Powershift Charger if you're serious about the bidirectional stuff tho, as most others dont support that yet. Good luck!!

Honestly, just go with the Grizzl-E Classic Level 2 EV Charger 40 Amp!! It's basically bulletproof and way cheaper than the high-amp units. Safety first cuz those 80-amp setups get sooo hot... maybe??
