Solid inverter for RV use, with some limitations

This inverter/charger has been used in a full-time RV for about two years and performs its intended function. It only supports a single 50A phase from the pedestal, which works but is a limitation. The switch from shore power to battery is seamless, often unnoticed during outages, making it a good UPS. It can be finicky with some generators, so an inverter generator is recommended for clean power. It is also heavy.

Pros
  • + seamless transition from line to battery
  • + works as a good UPS
  • + does what it's designed to do
Cons
  • − only single phase 50A input
  • − finicky with some generators
  • − heavy

Quiet at low load, suitable for another room or garage

Noise output is minimal at low load, and conversation over it is easy. It has not been tested under extreme loads, and it is expected to become somewhat louder when fully loaded. At least at low load, it is quiet enough to keep in another room or a garage.

Pros
  • + minimal noise at low load
  • + easy to talk over
  • + suitable for another room or garage
Cons
  • − expected to get louder under full load
  • − extreme loads not yet tested

Solid Build Quality and Two-Year Warranty

This inverter/charger offers noticeably better build quality than a previous unit that failed after two years. It is considered the best option available and includes a two-year manufacturer warranty. The higher price is justified by the expectation of only needing to purchase it once.

Pros
  • + distinctive build quality
  • + two-year manufacturer warranty
  • + long-lasting
Cons
  • − higher price
