What Ships and What It Needs to Run
Included: Franklin 4 in submersible motor, Franklin 4 in submersible pump, SubDrive solar controller, and flow switch with 30 ft (10 m) cable.
Solar array: panels and pole-mount racking are listed separately on our solar panels, racking and accessories listing; the array is sized to the package, your site and your duty.
Drop cable, splice kit, pipe and tank level switches: sized to your installation and ordered separately.
Check valve on 35 GPM and larger builds: Franklin supplies high capacity pumps in SolarPAKs without an internal check valve.
Overview
The SubDrive SolarPAK is Franklin’s system solution for solar pumping: Franklin motor and pump technology and a SubDrive solar controller in one package, built as a rugged, high-output system for remote and harsh sites. Maximum Power Point Tracking gets the most water from the array, soft start prevents water hammer, and the controller switches automatically to an AC generator backup when the array cannot supply DC.
The controller has a seven-segment display of real-time input watts and system status, an RS-485 port for remote telemetry, contacts for up to two level-control switches, and a flow switch input that detects dry run and protects the motor.
- High flow system for faster tank fill and significant water output
- Proven Franklin motor and pump technology for long-term reliability
- IP55, NEMA 3 controller enclosure minimizes the impact of wildlife, insects, dust and weather
- DC and AC power inputs with automatic switching between the solar array and an AC backup source
- Seven-segment display shows real-time input watts and system status
Genuine Franklin Electric equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.

Source: Franklin Electric Solar Products Catalog (M1782 01-25), pp. 5-23, flow vs. PV power curves for each SolarPAK, digitized and rounded down to 0.1 GPM (whole GPM above 100). Each figure is the highest flow on that head line, reached at the right-hand end of the line; PV power is the highest power plotted for the build. Head is total dynamic head as Franklin labels each line. Actual output follows the sun, the array and the temperature; at lower array power the flow is lower. One head line on the 10SDSP-1.5HP, 45SDSP-1.5HP, 35SDSP-3.0HP charts carries no label and is left out.
Before You Buy — The Limits That Decide the Fit
- The array decides the flow: size it with Franklin’s SolarPAK Selector or send us your site, head and daily water need
- Array open-circuit voltage must never exceed 410 VOC at the controller
- The 0.75 hp drive starts at 95 VDC and runs down to 75 VDC; the 1.5 and 3.0 hp drives start at 190 VDC and run down to 150 VDC. Franklin notes these limits are not an adequate array voltage for useful pumping
- Generator backup: 230 VAC single-phase, sized per the instruction manual; 104 °F max ambient on generator
Applications
Livestock watering, Tank and cistern filling, Wildlife refuges and game farms, Rural water supply for villages and homesteads, Irrigation systems and vineyards and Fountains, effluent pumping and rain harvesting.
