WORKING PRINCIPLE OF ON+ OFF MULTI-FUNCTION SOLAR AIR CONDITIONER:

On/Off Grid Wall Split Type Solar Air Conditioner works perfectly under AC only, DC only or AC+DC, high SEER, wide voltage design, works perfectly under normal and T3 tropical climate. 
It equipped with MPPT PV tracking system, utilize the PV DC power as priority. 
DC directly power the indoor&outdoor fan motors and the compressor. 
When the DC power is not sufficient, the AC power helps, thus achieve continuously power supply. 
Wide voltage design, freely use different PV panel configuration according to your installation space. 

Recommend Solar Air Conditioner Accessories:

• Solar Panels: 335W , 9 BB LINE, half cells poly crystalline or mono crystalline
• Qty of Solar Panels: 4/6/8 Pcs 355W Solar Panels.
• Solar Panel Array: serial & parrallel connection
• Connection Method: MC4 Connector
• Batteries: if install as AC/DC on grid, model, then, no need, if want 100% PURE SOLAR installation, we can built in batteries, OPzV Tubular Gel Battery or Regular Gel Batteries.
• Solar Charge Controller: if install as AC/DC on grid, model, then, no need, if want 100% PURE SOLAR installation, we can built in solar charge controller

This is the 4th generation solar air conditioner we've all been waiting for - designed for low cost, easy installation and a fast payback.
This unique solar air conditioning technology can work without batteries, no inverter, no controller - just plug in the solar panels and start saving up to more than 90% on daytime cooling or heating costs.
If you region without AC power supplier, we can inbuilt BATTERY, INVERTER, SOLAR CHARGE CONTROLLER too,
Namely, can meet your requirement of BOTH on grid installation or PURE SOLAR 100% OFF GRID installation!

Installation under model: AC/DC ON GRID MODEL:
During the day it runs primarily on solar power and only uses small amounts of power from the utility company as needed. 
Hybrid operation eliminates the need for batteries and allows 24 hours per day use of the system. 
The system primarily uses solar power, and mixes it with normal AC power. solar AC indoor unit
