0.4-37kW white plastic-shell MPPT solar pumping, 220V / 400V, single-phase and 3-phase output for agriculture irrigation, farms and deep wells.
The QB100-PV converts solar-array power into controlled AC output for water pumps across 0.4–37kW. Its verified white plastic-shell model branches cover 220V single-phase (SS2) and 3-phase (S2) plus 380–400V 3-phase output; final selection must follow the pump current, motor type and PV string data.
The product catalog states solar maximum-power-point tracking efficiency up to 99%.
The controller can start or sleep automatically according to available PV power.
Verified functions include PV overvoltage, overcurrent and over-temperature derating.
GPRS remote monitoring and IP54 cabinet versions are listed as options.
The table below keeps every verified power or model branch visible. Match the inverter by pump rated current, voltage, phase and application conditions—not by kW alone.

For a dependable quotation, also confirm the installation altitude, ambient temperature, enclosure requirement, daily operating schedule, water-source conditions and whether utility or generator backup is required. These details affect derating, cable selection, protection devices and the final AC/DC system design.
Installation and commissioning must be completed by qualified electrical personnel. Verify polarity, grounding, protective devices, PV open-circuit voltage and motor wiring before energizing. Apply the manual derating and reactor guidance for temperature, altitude and long cable runs.
Yes. The QB100-PV S2 is designed for PV-powered pumping. Confirm the PV string voltage remains inside the verified range for the selected 220V class · 3-phase 220V output model.
Backup input depends on the selected branch and wiring configuration. Do not connect sources simultaneously unless the selected model and protection arrangement explicitly support it.
Check the pump nameplate current, rated voltage, phase, motor type, head, flow and cable length. The selected inverter current must meet the motor requirement.
The standard solar-pumping architecture can operate directly from the PV array. Battery use is not required unless a separate project design specifies it.
Remote communication is optional or model-dependent. Confirm the required GPRS, 4G or Wi-Fi module before ordering.
Send the pump nameplate, PV module data, required head and flow, cable length and quantity. Our team will confirm the suitable model and project configuration.
