SubDrive SolarPaks include: Solar Pump, Solar Motor, Solar Controller, Flow Switch & 10m Cable for use with the Flow Switch.
The most important feature of the SubDrive SolarPak is it has available input for AC power backup (generator or mains power).

NEED HELP Selecting SubDrive Solar Bore Pumps?– you need to know the Total Head and the Flow Required. If you need help with this, please fill in the Quote Form or just contact me and I will be more than happy to assist you with your pump selection or inquiry. Here is some more helpful information to assist you when selecting a Bore Pump.
When solar power is not available, the controller can automatically switch to an alternate single-phase AC input such as a generator or inverter from battery, if available. The controller provides fault detection, motor soft start, and speed control. The SubDrive Solar bore pumps are designed to provide these features with the plug and play ease of installation similar to a single-phase control box.
The SubDrive Solar controller is a variable speed motor drive designed to run a Franklin Electric three-phase submersible induction motor. The solar system provides water to remote locations by converting high voltage, direct current from a solar array into alternating current to run a standard AC submersible motor.
The SubDrive Solar system can provide water in remote areas where normal power is either unreliable or unavailable. The system pumps water using a high-voltage DC power source such as an array of solar panels.
As the sun is only available during certain hours of the day and only in good weather conditions, the water is generally pumped into a storage tank.
Two level switches can be installed inside the tank to regulate the water level. There is more information below on monitoring the water level.
A flow switch detects if flow is below critical levels while the pump is still running. This serves as an indication that the well has run dry, or that insufficient power is available to continue pumping. The system will shut down to protect the pump and motor until the well, or adequate electric power, has recovered.
The SubDrive Solar controller runs at variable speed to match the changing power available from the PV solar array. Variable speed operation means there is no in-rush or surge of energy during the pump/motor start-up, helping to eliminate wear on the motor and pumping system. A leading cause of pump motor failure is the stress applied to the motor during a full voltage start-up. The SubDrive Solar variable speed operation ramps up the speed smoothly, which eliminates starting stress. This feature enhances long-term motor reliability.
The Franklin Electric SubDrive Solar is designed to be part of a system that consists of:

The most common method of controlling the flow of water is to use a single run input with a pressure switch. When the tank fills, it closes the double acting float valve, pressure builds up and the pressure switch open circuits which stops the pump. When pressure drops in the line it closes the pressure switch and starts the pump set.
2 Level Control Switch Operation
You can use up to 2 level control switches with the Franklin SubDrive Solar systems. When both switches are installed, the controller starts to pump and waits to shut off until both switches read “OPEN”. Once it shuts off, the controller then waits to run again until both switches read “CLOSED”. An example application (fig 10) is to use separate level switches to indicate high and low water levels. Parameter 1 should be changed to 2 in the menu controls.
1 Level Control Switch Operation
Alternatively, the SubDrive Solar controller may be configured to control the water level by using a single input switch. Parameter 1 in the controller is set to “1” by default for single level control operation. Once it is properly configured for a single active input with a control switch installed, the controller starts to pump and waits to shut off until the active switch reads “OPEN”. Once it shuts off the controller then waits to run again until the switch reads “CLOSED”. An example application (fig 10) would be to use a single-contact level switch that keeps the storage tank as full as possible without overflowing. for single level switch control, use only the “RUN” terminal connection.
0 Level Control Switch Operation
Lastly, the SubDrive Solar controller may be configured to not use a level control switch. Parameter 1 should be changed to “0” in the menu controls. In this configuration, the SubDrive Solar will always try to run the motor and pump water as long as there is enough power from the solar array or alternative AC power source.
All level control switch configurations are superseded by the FLOW SWITCH. If the flow switch detects low flow, it will OPEN and override the run signals sent by the level control switches to protect the motor and drive
I ordered a 12v water pump on line. Marion responded quickly with a personal communication (rather than the more robotic ones I’ve become used to lately from other companies) to confirm the delivery details which is refreshing. Ongoing communication was kept up re picking, dispatch etc and the unit turned up surprisingly quickly. Very happy with my first engagement with Strongman Pumps. They’ll be the first port of call in future. 5 stars.
Thank you for your assistance in processing our order over the weekend. The pond pump arrived and was left at our door when we woke at 6.30 am today. Fantastic service. Much appreciated.
I ordered my pump (Solar fountain pump with battery backup) on Friday afternoon and received it Tuesday. There was a substantial cost saving when compared with the local irrigation supplier suggested by the manufacturer. They would have had to order it in specially yet Strongman had stock and it was delivered to my door. Marvelous!!
Fast service and freight backed up with great tech support all made easy. Thanks Marion for your help.
Easy purchase and very impressive turn around between order and delivery. Thank you. (purchased a Franklin Electric submersible motor)
Thank you for your outstanding fast and friendly service. I highly recommend StrongmanPumps for easy ordering, great pricing and super fast delivery. I wouldn’t hesitate to order from you again in future.
Marion went above and beyond my expectations in listening to my needs and tailoring a solution for me. Amazing customer service and great product thankyou. (purchased a household pressure pump). Cheers Nick
I have bought two sump pumps from this business in the last few years. This is an excellent business as Marion has always been extremely helpful in choosing the best pump for the job. I have been very happy with how quickly my pumps have been delivered. An excellent business to deal with.
Thank you Marion for your assistance in choosing the right bore pump for my needs. Your estimation of pressure with respect to type of sprinklers was spot on. A good service.
