Topsflo TS5-15PV SS: Solar Model 5, 15 Watt Photovoltaic solar Stainless Steel water pump, optimized to run off a solar photovoltaic (PV) panel. Solar pump is designed as a circulation pump for a solar thermal water heater system. Stainless steel NPT fittings. Special feature: adapts to the changes in power from a PV panel as the amount of sunlight changes Maximum Power Point (MPP) tracking. No maintenance. Can be used with hot tubs, fountains, brewing applications or any liquid pumping, as the parts are corrosion resistant.
Makes simple split solar water heater system.
Runs connected to a 15 W+ solar PV panel
Solar circulation pump runs when the sun shines
Runs faster when more sun, more hot water
No controller, no probes, no grid power needed
Pump electronics are specifically designed to run with variable output from a solar photovoltaic (PV) panel. PV Solar pump is specifically designed to work as a circulation pump for solar thermal water heater split systems. Pump can start with little sun (capacitance soft start) 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. Eliminates the need for an electronic control system for solar energy water heaters. Also used with radiant floor heating glycol fluid circulation.
MPP tracking means that this pump will start and run when the sun is not strong enough to run other pumps, and will run faster with more sun. A capacitor system allows a soft start with almost no sun. The most common pump application is for water circulation in a split solar thermal water heater system. Electronic controllers historically cause the most trouble in a solar water heater system. Eliminate the controller with a solar PV direct pump, and the largest source of solar water heater system failures is eliminated. The great advantage of this pump in a solar water heater system is eliminating the need for an electronic controller in the system. Able to run efficiently with either a little sun or full sun.
