Solar pump selection guides covering pump nameplates, head, flow, PV sizing, inverter choice and quotation checks for water projects.
High head and high flow projects should be sized from the duty point, not from the controller price. High head and high flow expose weak pump selection fast. A system that works in a shallow well can fail badly when water must move higher, farther, or in larger volume. DC solar pump systems often reach … Read more
Panel matching is not just adding enough watts; the PV string must give the inverter the right voltage window under real site conditions. Many solar pump problems start with a simple mistake: the buyer matches panel power to pump power and forgets voltage. The pump may run at noon but start late, stop in clouds, … Read more
Solar VFD compatibility depends on voltage, phase, motor current, pump curve, PV input, and protection settings working together. Pairing a solar VFD with an AC water pump is not just matching kilowatts. A 4kW inverter can still be wrong if the pump voltage, phase, rated current, or PV input range does not match the site. … Read more
