Grid Point Designs

The Yeti type Chinese generators do have decent capacity and power, but they aren't made to last. We build Grid Point power boxes here in the United States, with name brand components like Victron Energy and Blue Sea. The batteries can go through 6000 full cycles before reaching their lifespan, so these systems are meant to last decades. Since it's modular, components can be replaced or swapped if something should fail.My kid had a converted ambulance. The ambulance did not have an on-board generator or a secondary 120v electrical system. One of those Yeti "solar generators" was the perfect choice for that application.
For my 37' motor home with 2 a/c units, a microwave, and an entertainment system, I feel like the on-board Onan is a better fit.
We have put a Grid Point power box in a Class A motorhome, but it's only meant to run one of his Air Conditioners. You are right, you would want an Onan or something like a dual Victron Multiplus system to run both.
