Smart. Solution – Hybrid Power Now anything is possible ! § Support for solar and an alternative energy source § Extend the pumping day for seasonal / peak requirements § Lower operational costs from grid or generator Note: Hybrid power is currently limited to PSk 2 -40 and smaller systems 17 © LORENTZ

What is Smart Hybrid Pumping? Mixing and managing different power sources to optimize cost and performance § § § 18 Plan to run solar for the majority of time and use alternative sources power for peaks, emergencies or to keep processes running Power blending and auto switch on / switch off means that all of the solar power is used and is “topped up” by grid or generator Operational costs of diesel and grid power are reduced © LORENTZ
