48v DC-Direct Solar Multi-zone Air Conditioning & Heating - 48,000 BTU 42 SEER

These off-grid 48v DC heat exchangers are the most efficient worldwide making it possible to power them exclusively from solar. Work with an Electrical Engineer, not a door-to-door salesman! Made for us to our specifications.

Compare 42 SEER to a standard 10 SEER residential heat exchanger which is already considered energy-efficient. That's a 420% increase in energy efficiency. 

If you only cool 2 bedrooms at night and do not cool those 2 bedrooms during the day, you might cut energy use to 60%. 25% of that means with this system you could use only 15 watts for every 100 watts your old AC system required with the same comfort!

Be anywhere on anchor or in the wilderness far from expensive RV campgrounds or crowded marinas yet in complete comfort without running a generator! Perfect for boats, RV's, tiny houses, to complete homes.

Cut the cord and experience true freedom!

• Incredible energy savings when you only turn on the rooms you are using
• Cool only the kitchen or office you are occupying by day completely from solar while storing extra energy in batteries for the evening
• Cool one room up to 16 hours from our 48v Lifepo4 280ah 15kwh Battery (10'x15' bedroom, hot climate, poorly insulated = 12,000 BTU) or 2 smaller rooms for 8 hours (equivalent to 2 Tesla Powerwalls)
• Reliability- Should there be a failure in any one zone or room it does not affect any of the other zones.
• Supplement cloudy days or when you have guests with a small, inexpensive 1-cylinder DC Battery Charging Generator that Automatically Starts up when Batteries Get Low and Automatically Shuts down when the batteries are 90% charged.
