IT WORKS DC Variable Frequency Technology
Air Conditioner Technology Background
It starts with the compressor which uses 95% of the power consumed by an air conditioner. In all ultra-high efficiency AC-powered mini-split units, household electricity enters the air conditioner and passes through a rectifier, a component that converts the incoming Alternating Current (AC) to Direct Current (DC). The DC current passes through a frequency driver which applies power to the motor. The frequency of the power determines the output of the motor, which can be digitally managed to precisely control the motors speed. Because DC power can be used more efficiently, all of the highest efficiency AC-powered heat pumps and air conditioners on the market use DC powered compressors.
In an off-grid solar configuration where an AC-powered air conditioner is running from inverted solar power, the power is actually being converted twice. First, the native DC power from solar panels is inverted to AC by the inverter, and then the power is immediately converted back to DC after entering the air conditioner. Sounds wasteful? It is, requiring more solar panels and more batteries as a result.
A key difference with our system – the DC4812VRF unit skips all of these conversions and uses the DC power directly without conversion loss.
The 48V DC Powered Solar Air Conditioner System
DC Powered Indoor unit
One reason that a DC Air Conditioner makes the best use of solar power is because there is no loss associated with converting DC power from solar panels into AC power to run a standard air conditioner.
100% DC Powered Outdoor unit
Using standard solar panels which produce native DC power, the 48V DC air conditioners avoid the inefficient addition of an "inverter" that converts solar DC current into AC current.
DC Brushless fan motor
We use 48V DC brushless fan motors for both indoor and outdoor units. DC brushless fan motors can greatly reduce energy consumption, and run with super low noise. Plus, the use of a brushless permanent magnet motor driver provides a variable frequency drive that allows the system to dynamically adjust its capacity based on conditions
Solar Panel
We suggest you to connect 4 or 6 pcs 275W-330W solar panels to drive each solar air conditioner. Both mono-crystalline and poly-crystalline solar panels can be accepted.
MPPT Solar Charge Controller
A Solar charge controller protects the whole system and provides stable power supply.
Battery
Batteries are the energy bank to reserve energy. We recommend you use 4 x 12V deep cycle gel solar batteries Depending on the system selected and the hours of battery operation you require, you can select the AH of your batteries.
