Will a 12v - 7 watt solar panel power this pump?

No - a 7 watt panel will not power this pump. The pump draws around 1.7A and so the power requirements at 12V are (12V)*(1.7A) = 20.4 Watts. Three of the 7 Watt solar panels hooked up in parallel would do the trick.

Sorry for the late reply.Unfortunately I cannot help you with this situation but I suggest that you check the specification of the 12v water pump.With my best wishes to find the solution

No. You would need a 12v battery and use the solar panel to recharge your battery

I wish I could answer that. I power mine with a deep cycle battery. I can say that it uses very little power to work and works very well. It is a really great value

Absolutely. Just make sure the solar charge controller is 12VDC and rated appropriately for the output of the solar panels.

I don't believe it will work... specifically with the minimum one battery set up. It may work with several batteries but suggest you contact Grape Solar directly for assistance. They have been very helpful with my questions over the phone, (1.541.349.9000). I have operated smaller pumps for brief period but not 1.5hp. I believe you are also going to be using a lot more than the 400 watt output of the 4 panels... you may need to be generating closer to 1500 watts to continuously run the pump.

This is compatible with a 12volt system as with any solar panel you will require other parts to macke this work saflely and efficiently as a renewable energy system Hope this info helps you Joe

I would not recommend hooking this directly to a solar panel...the pump will be damaged at low output voltages from the panel...instead use the solar panel to charge a small 12V battery that in turn powers the pump. Put a low battery cut-off between the pump and battery to protect the battery. Depending upon how long you want the pump to run a small 6-12 Ah battery would be sufficient for 8-10 hours between charge cycles.

Would I be able to use this with a 280 watt panel to charge a 12 volt battery bank of 4 GC-2 6 volt batteries? Need to keep bank at 12volts to run bilge pumps: Grape Solar GS-P-280-Fab1 280-Watt Polycrystalline Solar Panel (Discontinued by Manufacturer)

Solar panels are really meant to be used to charge batteries, generally (highly recommended) via a charge controller. 12V devices (such as your pump) can then be connected directly to the battery terminals -- the battery acts as a voltage/current buffer. The batteries are generally deep-cycle (such as RV/marine batteries). The problem with connecting a pump directly is that the voltage from the panels will fluctuate depending on load and solar loading, and not all DC motors do okay with fluctuating voltages -- you'd have to check that this is okay with yours.

Yes. I have the Goal Zero Nomad 7 Solar Panel, which puts out 7 watts of power and I charge these batteries with it via the 12v attachment and it works great!

No you cannot. The panel/charge controller cannot run any loads without being connected to a battery. The energy supplied to the load must come from the battery. There is one exception I have seen. There are some 12V water pumps that will run directly off of a solar panel without the need for a controller or a battery.Renogy Tech SupportSR

Its only a 5 Watt panel so no. Running something from a solar panel, without a DC battery, isnt practical anyway if you need any sort of a constant voltage.

I believe the pump itself operates on 12vac and probably draws less than 1-2 amps. I recently purchased a replacement unit and it is still working OK.

You're going to need a 110V - 12V adapter that has a cigarette lighter outlet. You can find them on amazon, but you don't want to cheap out on the adapter. The power usage isn't listed on the pump description, but an educated guess suggests you might need an adapter that can pump out 6 or 7 amps. Motors are power-hungry, unlike 12v electronic devices. If it's occasional 110v usage fine, but if you're using it all the time on 110v, you're better off getting a pump that plugs into the wall.

It is rated for 300 watts so as long as your pump does not exceed that it will

One 85 watt panel Should deliver around 7 amps at 12 volts in full sun. If you have all 4 panels connected through a single (7 amp) controller, it is way overloaded. Sounds like you might need 3 more controllers or simply a bigger controller unit.

depends on the size of the pump, but most are 1/3 or 1/2 HP and need less than 1000 watts, Its a safe bet this generator can handle it

No. This unit uses 18 and 20 volts on a multipin connector, you could use a small inverter in front of it to run from 12 volts.

If your 10 watt solar panel will keep your 12 v. battery charged it should work.
