Solar pump selection guides covering pump nameplates, head, flow, PV sizing, inverter choice and quotation checks for water projects.
A practical guide for buyers matching well depth, pump nameplate, total head, flow, and PV array data before choosing a solar pump inverter. A submersible well pump can run on solar power when the inverter matches the pump motor and the PV array supports the required voltage and power. Do not choose by well depth … Read more
A practical guide for EPC teams comparing solar-only pumping, water storage, battery backup, and hybrid AC backup before quoting an irrigation project. Battery storage is not the default choice for most solar water pump projects. Start with daytime pumping and water storage first. Add batteries only when the site must pump outside solar hours, has … Read more
A field-focused guide for buyers checking whether a 380V three-phase well pump should use Solarseeker’s SP4 path. A 380V solar well pump system usually fits deeper wells, larger irrigation demand, and three-phase AC pump motors. SP4 is the safer product path when the project needs 380V three-phase output, wider power coverage, PV input control, MPPT … Read more
A practical selection guide for buyers who need to confirm whether a 220V single-phase pump can run from solar power. A single phase solar pump inverter is used when a 220V single-phase AC pump needs to run from solar panels. Before choosing a model, check the pump nameplate, rated current, starting behavior, head, flow, cable … Read more
A practical checklist for EPC teams, distributors, and pump buyers who need an accurate solar pump inverter recommendation before ordering. A pump nameplate gives the basic electrical data needed to choose a solar pump inverter, but it is not enough by itself. For accurate model selection, send the nameplate photo plus pump power, voltage, phase, … Read more
Learn when a 0.75kW solar water pump fits small wells, irrigation, and tank filling, with PV sizing, voltage checks, and quote risks.
The common mistake is sizing the PV array as if a pump were a light bulb. A 5HP pump does not need only 5HP worth of panels. The inverter must start the motor, hold frequency, survive weak sunlight, and keep enough DC voltage in the working window. For a 220V single-phase pump, start with PV … Read more
On a deep well site, the real question is not “How many kilowatts is the inverter?” The first question is whether the pump can lift enough water from the real water level to the discharge point, at the flow the buyer needs. Sizing a solar water pump for a deep well starts with head and … Read more
This is Andy. I've spent the last eight years in the solar pumping trenches, and one sizing mistake keeps showing up in irrigation projects: people match the inverter only by motor kW, then ignore the DC voltage window and field conditions. That shortcut costs water. The pump may start late, trip at noon, or run … Read more
A practical selection guide for EPC irrigation projects This is Andy. I have spent the last eight years working on solar pumping projects. One mistake still shows up often: buyers choose the inverter phase by price, not by pump load, cable distance, or daily water demand. For solar water pumping, single-phase and three-phase are not … Read more
