Limited energy from solar panels requires appliances that consume low power while maintaining the same performance as normal units. Maxima aircons use double-rotary compressors, pure copper tubes evaporator, smart system controller providing a 3-stage algorithm among many other features that lower the energy consumption in excess of 40%. Moreover, these airconditioners use direct current (DC) power, the same type as produced by solar panels and stored in the battery. By avoiding conversion from DC to AC power, Maxima Airconditioners provides holistic solution for solar applications.
