FREQUENTLY ASKED QUESTIONS
What are the different types of solar air conditioners?
Zamna Climate offers two types of solar air conditioners, an AC-DC Solar Ready Hybrid Air Conditioner, and an all-DC off-grid/telecom air conditioning unit. There are also other types of solar air conditioners in the market, for a good analysis of the various systems available, see the page called compare solar air conditioners.
How does the 12KACDC air conditioner work?
The 12KACDC operates like all normal ultra-high-SEER mini-split heat pumps, but accepts solar directly from standard solar panels. When abundant solar energy is available the 12KACDC can operate with only solar panels as a power source. For best operation at full speed, on cloudy days, or to run at night, an optional grid-power AC connection is recommended.
Does it have to be connected to main power?
No, it can use only power from solar during strong sun hours. An AC power source is recommended for cloudy days or to run at night. The AC source can be supplied by utility power, an inverter, or a sine-wave quality generator.
How much power does it use?
Because it is a SEER 22 system (certified) it uses very little power. Normal operation consumes about 600 watts of total power.
How difficult is it to install?
It installs exactly like a normal mini-split air conditioner, then you can simply plug in the solar panels. In the USA a EPP licensed is needed to handle r410a so we recommend you hire a licensed HVAC technician to perform at least the final part of the installation.
Does it need batteries?
No, the 12KACDC does not need batteries. Any shortage of solar power, such as at night, is made up for by pulling the power from the normal AC power supply.
Is the system certified for safety and performance?
Yes, the 12KACDC has been fully tested and is listed by ETL/UL 60335
How much does it cost?
The final installed price will vary based on accessories and installation requirements. Systems range from $2000-$5000.
What is the SHF (Sensible Heat Fraction)?
This refers to the balance of sensible vs. latent heat removal (de humidification) in cooling mode.
Cooling Mode： AVERAGE DATA - Sensible heat（W） 2524.2 Latent heat（W） 705.4
SHF for heating mode is always 100% sensible.
