Powerful inverter, but difficult AC connectors

This inverter performs very well in many respects, but the AC input and output connectors are a serious flaw. They require 6 AWG wire and 18mm ferrules, which are hard to find and often sold only in large packs. The units do not include the ferrules or the needed crimper, and the connection process is fiddly, requiring a small screwdriver and careful insertion. Installation of eight wires becomes a lengthy process of research, ordering, and repeated attempts.

Pros
  • + Strong inverter performance
Cons
  • − Difficult AC connectors
  • − Requires 6 AWG wire
  • − Requires hard-to-find 18mm ferrules
  • − Ferrules and crimper not included
  • − Fiddly wire insertion process

Reliable inverter for RV solar setups

This inverter works very well and has been used for half a year in an RV with solar. Two units were installed at the same time, one 24V and one 12V. The 12V version offers more software options, but for an RV setup the 24V version is preferred because it requires smaller cabling.

Pros
  • + works well
  • + more software options on 12V version
  • + smaller cabling on 24V version
