12,000 BTU DC Air Conditioner For Off-Grid Solar & Telecom Applications
https://www.practicalpreppers.com/air-conditioning/dc-air-conditioner-all-dc-for-off-grid-use
If your power source is native 48VDC as part of a telecom or off-grid solar application, HotSpot DC4812VRF all-DC air conditioners are your most efficient cooling choice. DC48 air conditioners can substantially reduce power supply/generation costs and battery requirements. An all-DC system means you get the advantage of extreme high efficiency without the need for inverters.
The HotSpot DC4812VRF is a purpose-built DC powered air conditioner heat pump for native DC power. It’s designed to conserve power, and operate reliably for many years without maintenance.
SeaSpray Anti-Corrosion technology protects circuit boards, condenser, evaporator, compressor, and fan motors from salt air corrosion.
The DC4812VRF is a variable capacity, variable speed, variable refrigerant flow unit. There is no other solar or DC air conditioner like it on the market.
