SunStar FAQ

Do SunStar DC freezers need an inverter?
No. The DC chest models connect directly to a 12V or 24V battery bank and select the voltage automatically. The 10 and 16 cu ft upright models accept 12/24V DC or 115V AC.

Can a SunStar chest freezer be used as a refrigerator?
Yes. The thermostat switches each chest model between a full freezer and a full refrigerator.

How much power do SunStar appliances use?
SunStar lists typical draws from 55 W (8.2 cu ft DC chest and 10 cu ft upright) up to 105 W (21.5 cu ft DC chest). The 16 cu ft upright is listed at 60 W typical, within a 40–110 W operating range.

What is the difference between the upright and chest models?
The upright models have two compartments, each with its own compressor and thermostat, so you can set them separately, and they run on DC or AC. The chest models are single-compartment units sold in separate DC and AC versions.

What warranty do SunStar appliances have?
Every SunStar model carries SunStar's 2-year performance warranty. OffGrid Horizon is an authorized SunStar dealer.
