AIMS Power 2000W Pure Sine w/ Transfer
A low-cost listed 2000 W inverter with a transfer switch, for RVs that already have a converter. It undercuts the Freedom X 2000 by a wide margin but idles higher.

The AIMS Power 2000W Pure Sine w/ Transfer rates 3.5 among 1,100 to 2,000 W 12V inverters; the AIMS Power 3000W Inverter Charger rates 3.2 among inverter-chargers ones. The AIMS Power 2000W Pure Sine w/ Transfer costs $519.53 less ($469 vs $988.53).
AIMS Power 3000W Inverter Charger
#32 in Inverter-chargersFull review
A low-cost 3000 W low-frequency inverter-charger for off-grid cabins and backup systems with big motor loads. The idle draw and lack of a listing make it a poor fit for a van or RV with a small battery.
