Renogy makes a great inverter we use for all base builds. The inverters come in 1000w, 2000w and 3000w specs. We can calculate what wattage you’ll need based on the appliances being used.
Option Two: Victron
Victron components are the best option. The MultiPlus contains shore power charging (converter 120v -> 12v) and an inverter(12v -> 120v). It basically sums up what you need for you dream van. The Quattro offers higher amperage and two AC inputs (shore power & generator).
When it comes to power upgrades, there are many different configurations to suit your needs. The difference between 100aH battery bank and 400aH is a big difference and will really matter when you’re off grid.
