Victron Phoenix 48/500
#4 in Up to 1,500 WFull review
A good size for an efficient fridge, CPAP or entertainment loads on a 48 V system. Low idle draw means it can be left on all the time.

A small, frugal inverter for electronics on a 48 V system. Good for a dedicated low-power circuit next to a larger inverter.
