Two rigs. One sun.
Snoopy and The Beast go where the plugs don’t. Both run Go Power! PowerTrak systems. Here’s what’s on the roof, what’s behind the walls, and what it keeps running out there.
I’m a Go Power! | Dometic brand ambassador. They supplied the PowerTrak systems for both builds. What I tell you about how it performs is mine, the good days and the bad ones.
What’s running where.

Inverter/
charger 3,000W pure sine AC - Run The loads Coffee, Fridge, Starlink, Laptop + 2 Screens, Occasional AC use as needed for sleeping and a fan/air purifier that runs at least 12-18hrs a day
Plugged in?The inverter/charger switches to shore power when plugged into generator or campground power and tops up the bank at up to 150 amps per hour. I usually see it running in at 80-120amps depending where I am getting input from and what else the rig is running while it charges. Solar input also adjusts this number.
Keeping scoreThe PowerTrak Screen shows solar in, battery state, and what’s pulling, all in one place.
What a day actually costs.
Draw versus harvest, read off the PowerTrak Screen. Real numbers, not brochure numbers.
