- Runs faster when more sun, more hot water
- No controller, no probes, no power needed
- Creates Off-grid split solar water heater system
- Powered directly by 10 W solar PV panel
Pump electronics are specifically designed to run with variable output from a solar photovoltaic (PV) panel. Pump can start with little sun and uses Maximum Power Point (MPP) tracking to run faster when there is more sun, and therefore more heat to be taken from the solar thermal panels.
