Background: Current inverters for solar power systems are prone to failure and the leading cause of malfunction in solar systems. It is desirable to use transformer-less topologies that are more reliable and longer lasting. Using inverters that do not contain transformers results in higher efficiencies significantly lower size weight cost and complexity. Many transformer-less inverters face the problem of large capacitive ground currents impeding the flow of electrons through the system.

Pumped-storage hydroelectricity (PSH) is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost off-peak electric power is used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power.

SEABELL'S STREAM is a micro-hydropower generating system that can generate electricity in ultra-low head with on/off-the-grid source. The pondage created by the controlling sluice gate prior to the inlet regulates the potential energy thereby controlling the kinetic energy that eventually passes through the runner chamber. Its patented vertical dual axis runner structure and bell mouth shape inlet leading to the orifice optimizes input energy at the center maximizing the intake.
