Hybrid solar allows your pump to operate with solar only, to combine solar with grid or generator power by blending power sources or to operate only with grid / generator.

Addressing the challenge of expanding pumping time in solar applications

Solar power is the cheapest and cleanest energy source available source available for water pumping.
In applications where there is a higher seasonal or peak water consumptionvdemand, or where pumping is required outside of daylight hours, then solar power alone might not meet the requirements.
PSk3 allows a second power source to be connected which complements the solar power. Based on the defined water need PSk3 will prioritize solar and blend in the second power source.
This hybrid function significantly reduces energy costs not only in offgrid but also on-grid applications.

Visualizing hybrid Operation

The PSk3 does not switch between sources but blends power seamlessly when a second source is needed.
In this diagram you can see the power from grid / generator (red) and the power from solar (yellow). In this example PSk3 has been set to run from 05:00 (5am) to 22:00 (10pm) at a constant speed. Power choice and blending of power is automatic.
PSk3 uses all of the solar power available and uses the second power source to support solar. This is done automatically. Even starting the generator in the middle of the night if this is what is required to meet the defined water demand.

Time, amount of water, pressure, flow, or tank levels can all be used to decide when the pump should run. This automation removes the risk to people and machinery of having to switch multiple power sources using complex switching sequences.

Other systems that are marketed as hybrid are only switching between power sources, we would call these dual power rather than hybrid. PSk is blending powers which can make savings of 60-70% against the operation of dual power systems.

Simple to install but with massive flexibility

PSk3 is fast to install and easily configured in 2 minutes. To run a solar direct system only DC input, motor wires and a run dry sensor connection is needed. The system below shows what can be done with PSk3. PSk3 has all of the sensor inputs you will ever need and all of the software is included in the controller for automation. With PSK3 you can fully manage your water system.
