COLDINNOV sells several models of split solar air conditioners. With a robust and proven design, they can cool the indoor air of a home or business premises even in the absence of a reliable power grid.

Powered by photovoltaic solar panels during the day or by batteries at night, our 100% solar air conditioners can also be connected to the grid if needed, with automatic switching from one source to another. They are particularly suitable for areas with little to no connection to the electric grid, such as Africa or South America.

Observation: air conditioning usage is growing more and more in the world; the pollution it generates, too

Who has never dreamt of a bit of fresh air during a heatwave? With global warming and the increase in average incomes in emerging countries, air conditioning is growing very fast all over the world. The resulting sharp increase in electricity consumption will, according to the International Energy Agency, will lead to a doubling of CO2 emissions induced by air conditioning between 2016 and 2050.

Similarly, in areas with little to no electricity grid, air conditioning is most often provided by generators, that are polluting and noisy.

The FREECOLD solar air conditioning partly overcomes these problems. Our modular and easy-to-install solution offers access to cool air while avoiding the use of a non-existent or polluting electrical installation. Both domestic and professional premises can, thanks to FREECOLD, now be air-conditioned using the free energy of the Sun!

Mono-split solar air conditioners CS09 and CS12

FREECOLD by COLDINNOV solar-powered air conditioner

The CS09 and CS12 mono-split solar air conditioners make it possible to cool a house as well as a technical room using the energy of the Sun. They use a solar power-plant linked to an inverter and batteries to ensure operation during the night. A coupling with the electricity grid is also possible, with automatic switching from one source to another with priority to photovoltaics.

Their rugged and proven design ensures optimal operation even in the tropics, up to 50°C outdoor temperature.

To limit the cost of the solar installation, our air conditioners are energy class A++, guaranteeing low power consumption and optimal performance. They are also studied to ensure maximum acoustic comfort with a sound volume between 28 and 41 dB(A).

The power of the solar power station and the capacity of the batteries are adjusted according to whether the use will be professional (air conditioning during the hours of the day) or domestic (air conditioning in the evening after sunset).


The mono-split solar air conditioner comes pre-charged with R410a refrigerant. Its 2 units, inside and out, are easily connected thanks to a mounting plate and an installation support studied to facilitate the junction of the connections.

Maintenance and service are also facilitated by easy access to the filters and the removable frame for quick access to the fan.

Mini split solar air conditioner MSP-500

Currently in development, the mini-split solar air conditioner is designed to cool small premises, professional or technical as well as domestic. Its particularity is to provide a fairly low refrigeration power, 500 to 750 W, while operating in 24 VDC. This unique configuration makes it possible to reduce the area of solar panels, as well as to eliminate the inverter, which is expensive and has a limited service life.
