Compact non pressure solar water heater relies on the nature circulation of the water between solar tubes and the water tank.Thermosyphon systems work on principal of heat rising. The water enters in the bottom of the collector and rises to the tank as it warms. The advantage of this system is that solar heat is stored in a well-insulated tank, so hot water can be used at any time without the penalty of overnight losses. Moreover the insulation of the tank can protect heat during 3 days without heat loss.

Modular system is easy for transport and installation. Tank in 150/300 liter version with optimized heat insulation. Woven toughened solar safety glass. Qualified and recyclable materials ensure a long service life and high environmental compatibility. Maximum heat transfer between the absorber sheet and the header tubes thanks to optimized brazing or laser welding technology. Statically tested mounting solar collector system can be installed on flat roofs.

9000-24000btu Wall mounted split Type Pure 48V DC 100 percent Off grid solar air conditioner.

ACDC on grid solar air conditioner; work with solar panel and grid electricity. Even when air conditioner dont work, solar panel can still generate power and make the power meter converse ,to reduce electricity bill for home using. Which is not for off grid , but in day nearly dont use grid power (saving 90% if comes with suggested solar panels),and in night use grid power,dont need extra inverter or controller.

When the power on, the compressor start working, it compress the refrigerant from low pressure to high pressure, low temperature to high temperature, then discharge to heat ex-changer of the solar collector, In sunshine time ,the vacuum tube can absorb the sunshine to heat the water of the water tank, then the hot water will translate the heating to refrigerant by the ex-changer, then help the compressor heat the temperature and increase the pressure of the refrigerant again,so it  just need use the small compressor driver the system running, just use the less power to cool or heat the room,to save more energy.
