can this be powered by a 12vdc solar panel with a open circuit voltage of 20vdc ??

I have mine connected to a 12v battery fed by a 20 vdc panel. It works well in that configuration.

Yes, it can be powered by 12vdc. I power mine with two 9 volt batteries connected in series. It works quite well.

I am using a 100watt panel made by Global ICP. Is your panel 12volt output? It must be for this charger. The actual output will be higher but not over 24, which is the next stage up. My panel puts out 19.5 volts directly. If you have a muilti meter, check the output voltage if you do not know.Best to look around and get a book on solar. Plenty available. Learning first will help prevent mishaps or damage to your expensive equipment.

Hi, For this panel a 10 Amp Controller will work and be expandable up to 100W at 12V. Thanks, Renogy TO

Sorry, I can't see how that could possibly work as this device charges AA and AAA sized batteries from a standard 125VAC outlet/power source. I have no idea what would happen if you connected and 12VDC battery or solar panel to it, but I'd bet that it wouldn't be good. A better idea would be to find a small 12VDC to 125VAC inverter to connect your solar panel to, and plug this charger into the inverter. Yet another idea, see if Duracell, Energizer, or any aftermarket manufacturer actually make an automotive/12VDC charger. Good luck.

The Sunforce 60032 is rated for "12V" solar panels. These typically have an open loop voltage of around 21 volts, or so. It's interesting to note that a solar cell is a current, not voltage source, so it tries to deliver a constant current and raises the voltage up to a maximum as the load is reduced. Power output is voltage times current. In the open loop configuration (no load) the voltage is maximized but the current is zero. In the short circuit configuration the current is maximized but the voltage is zero. In both these cases the power output is zero watts. To draw power from the panel requires a resistive load so that both the voltage and current are non-zero.

Yes for the solar panel you must have a similar device like the following to regulate the voltage from the solar panels: "Renogy 10 Amp PWM Charge Controller Regulator Off Grid for Battery Charging". The panels have a tendency to make more than 12 volts and must be regulated.

Yes; but it has a 110 volt signal amplifier that would need to be run through an inverter. Or you could get a signal amplifier that is 12 volt.

If I understand your question correctly. your requirement is for a 400 watts solar input and if 408 watts of solar input is ok, I am assuming your question is for an off grid system (charging batteries). Question is if your your charge controller can accommodate additional 8 watts of input or ignore this additional watts without damaging any of the equipment. Please check the documentation of your equipment (charge controller) if it will work properly with the additional power provided by the solar panels. Normally additional power provided by the solar panels is ignored, one should make sure that electrical specs are matched with the solar input with the charger such as input voltage 24v panel and 24v charge controller input. Output from the charge controller should be matched with the battery voltage such as 24v solar panel, 24v charger and 24v battery, if different use an MPPT charge controller which can accept higher voltage from the solar panel and charge a lower voltage battery such as 24v panel, MPPT charge controller and 12v battery. Hope I have answered the question.

I would assume it could as long as the solar panel is designed to provide 12 Volt DC current. More than likely you will have to install a transformer to go from AC to DC power. Since this 12 V bilge pump pulls such a small amount of DC power from a battery I can't see any advantages to solar power unless solar power is all you have available.

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

I don't see why not, I have mine hooked up to my batteries so basically I'm using it like a multi-meter.as long as you're not going over the voltage rated for the meter.use caution as most 12v panels exceed 20v open curcuit.

Yes. I have a Thunderbolt Solar Panel kit from Harbor Freight Tools that came with a Voltage controlled that the panels connect to as well as a deep cycle battery. I have these LED bulbs wired to the 12vdc output and they been working great for about two years. Hope this helps. Lee

This panel can be used for 12v system, provided appropriate charge controller is utilized. One will need MPPT type charge controller.

Sure, but you will want to make sure that you have the solar panel hooked up through a contoller/regulator to avoid overcharging the battery. This is true with any battery.

The panels can supply between 12volts to 30volts and above depending on the sun's radiation. However, for a 12volts system you need a charge controller connected between your panels and the batteies. This will give you the required 12volts to your system with no worries.Hope that helps.

No. No and No. No solar panel is designed for direct load to a cooler. Designed to trickle charge a battery for maintance only. 1.25 amp at 12 volts max output under perfect conditions.

Ya you can run this with photovoltaics. The only thing is that this is 120VAC so you will need an inverter from the solar panel to the pump. More than likely there are DC pumps out there and you could hook directly to it. It will start pumping when the sun comes up and stop when it goes down. If you want it to continuously run then get a larger solar panel --> charge controller-->battery-->pump. My estimate since pump is 6 watts get at least an 18-20 watt panel then a battery that will last you through the night, 6 watts * 18 hours * 2 (oversize it) = 216 watt*hour battery.
