DC Solar Air Conditioning Frequently Asked Questions

This FAQ is for the DC4812VRF Model Only. For ACDC12 hybrid AC-DC FAQ please go here.

How much does it cost?
The DC air conditioner by itself is $1,795. Complete systems range from $3,995 and up.
See complete systems pricing here.

Can we get quantity discounts?
Yes, please contact us.

How much power does it use?
It uses ~/< 500w under normal running conditions. Max power is ~/<1000w.
See the technology & performance data.

What is included?
Includes the indoor unit and the outdoor unit. It does not include PV panels, batteries, charge controller or connecting lines. We can offer the unit by itself at this price or we can help put together complete systems.

How many solar panels do I need?
You need at least 4 solar panels, with 6 or 8 used for systems that need to operate longer hours each day. For examples of pre-designed systems, see the section on complete systems.

How many batteries do I need?
A minimum configuration is 4 x 12v deep cycle batteries depending on how many hours per day the system will need to operate. For pre-calculated examples, please see the the section on complete systems.

What about the connecting lines?
These usually cost around $95 and up depending on length. You can specify this when you order or your installer can make this part on-site to the exact size needed using standard parts. Max length 65 ft. (20m)

What else do I need?
You need a charge controller and a method to mount the panels. We can provide standard PV solar panel mounting hardware and charge controllers, please see complete systems.

How large of an area will it cool?
It is a one-ton (12,000 BTU) unit. Normally a 1 ton system can cool 500-700 square feet.

What about coastal or salt-air corrosion?
All units manufactured after Nov 10 2013 have anti-corrosion air conditioner technology included as a standard feature.

How does it work?
Please see DC4812VRF Air Conditioner Technology

What about DC telecom cooling applications?
We can offer 1+1 and 2+1 redundant backup air conditioning systems that balance run-time between 2 or 3 units, with automatic failover and alarm output. We also provide low-ambient cooling options for server rooms in cool climates. For more telco related application information please email us or give us a call at +1757-410-8640.

Can I become a dealer?
Yes, we work with solar and HVAC companies in the USA and around the world. Please contact us.

Do you have other sizes?
The 12000 BTU system is the only size we currently produce. However, two or more of these systems can be combined for 24,000 BTU or more, and share a single solar array, charge controller, and battery plant. Also, because the systems have infinitely variable capacity, each unit is very effecient when running at 3000 BTU, 6000 BTU, 9000 BTU, etc. So any capacity requirement from 3000 BTU and up can be met.

Do you have multi-head indoor systems?
We have only a single indoor unit available. However, two or more of these systems can be combined for 24,000 BTU or more, and share a single solar array, charge controller, and battery plant.
