  • Solar DC pump package with controller

    Ive seen a promotion deal online for a dc submersible pump including 100Wp panel and a controller. Pict below.

    I think the controller is just a pmw chargecontroller.

    They do not describe that you also need a battery.

    My question is:
    ​​​​​ can anyone tell me if i can run this pomp without a battery?
    Specs:
    12V Water pump : SFBP2-G96-08
    Cable 10 feet (3m)
    Voltage 12V DC
    Amps 4.0 Max
    Flow Rate(lph/gph) 360/96 1.6 GPM (6 LPM)
    Maximum Lift 230 Feet (70 Meters)
    Maximum Submersion 100 Feet (30 Meters)
    Material High Strength Engineered Plastic
    Inlet 50 Mesh Stainless Steel Screen
    Outlet Port 1/2''(12.7mm) Barbed Fitting
    Internal Bypass 105-110 PSI Max(7.2-7.5BARS)
    Motor Permanent Magnet Thermally Protected
    Pump Design Positive Displacement
    3 Chamber Diaphragm Pump

    That pump may work just using the 100watt panel but the charge controller does have the ability to charge a battery which will keep the pump running even if the sun isn't out.

    Since that panel can deliver a max of 4 amps your battery should not be bigger than 45Ah

      So if i only connect the panel and pump to the controller (no battery) the pump will run with that 100Wp panel

        It is hard to say what will happen. I do know that unless you have perfect sunlight hitting that panel the pump will not run to it's full potential and may be so slow it doen't pump and water iy you have too much of a head.

        A battery will even out the running of the pump to keep it from sputtering or slowing down due to low sunlight.

            I would confirm with the vendor that it will work in the mode you chose.

            Batteryless systems usually use a Linear Current Booster to run a simple DC motor. LCB's don't want a battery. The picture looks like a conventional battery controller (but it's a tiny thumbnail).

              That is a terrible photoshop mash-up of some components that used to be sold by "Eco-worthy". It requires a battery to function properly.

                Sounds like a deal. My search shows the pump costing that much alone and that pump model being 24V. Post a link, I might buy one.

                      No. that is a link to a DC-DC module.
                      This is a link to a solar LCB

                        But, it is amazing the price difference. A similar BUCK converter can be changed into a linear current booster for 50 cents. That 24V pump kit with panels costs about $380 in the US.

                          No. The charge controller requires a battery to work.

                          The pump looks like a Shurflo 9300 knock off. The Shurflo pump can be ran solar direct or with a LCB. I run one on my well. Being a knock off I can't say if that one can.

                            The price of solid state components in quantity has become extremely low. But a practical product
                            still needs design, mfr, marketing, and other overhead. If the demand is small, the price may be high.

                            What we need is more public info on how to convert cheap components to do specialized jobs like
                            an LCB. Bruce Roe

                              I have already ordered and expect to recieve it within 2 weeks. I will then try directly to the panel and also with a dummy battery connected to the chargecontroller. Still have an old motorbyke battery. Only for some pumping each day a motor/car battery is i think no problem. The panel gives more watt than the pump with full sun.
