The Renogy Pro 3000W Pure Sine rates 4.1 among over 2,000 W 12V inverters; the Victron MultiPlus-II 12/4k 120V rates 4.0 among inverter-chargers ones. The Renogy Pro 3000W Pure Sine costs $649.01 less ($455.99 vs $1,105).
For larger RVs and cabins that leave a big inverter on around the clock: its idle draw is a fraction of most 3000 W units. Hardwire it into a panel to use the full output.
