Will this charger operate when plugged in a Solar panel that generate 7.5 watts of peak power ? (and has a 12v output)

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!

that's an interesting use of the solar panel. since this charger has a 12 volt input. the input voltage is not critical and the current requirements are small so this should work .. be careful about polarity and be aware of some safety precautions. lithium batteries have complicated and critical charging requirements. however these are taken care of by the chargers internal circuits .. don't try to charge the battery without those safety features. lithium batteries should not get hot at this charge rate. you might want to watch carefully for a while to be on the safe side ... you might want to check the solar panel output voltage to make sure it is at least 8 volts and doesn't exceed 16 volts. while this technically should work you should consider it an experiment until someone has actually tried it

If you are asking "can I use this to power a battery charger" the answer depends on what the charger needs for power. There should be a label somewhere on the charger listing volts and amps. If the label lists 12VDC and no more than 1 Amp or 1000 ma then this power supply will work. If you are asking"will this work for my 12V battery charger" the answer is no. You need a power supply rated at 14.5V to charge a 12V lead acid battery.

I have one installed in a metal box on the roof. It has already been down to -10 F and probably to 100 F. That said, you may want to look at a MPPT charger. It seems you never get enough power out of a solar panel and the MPPT charger can get up to 30% more power to the battery / load. Its because a solar panel is a constant current device. The current is a function of how much light is hitting the solar panel and with a PWM charger you are pulling the voltage down to the battery voltage instead of allowing it to work at about 19 volts, which is the maximum power point for most 12 volt panes.

Well that depends.are you going to run the pumps all night? I use my panel to charge a 12 volt,110 amh battery that runs 12 volt lights through out the house. Works absolutely great!

Some solar panel controllers need to have 5 volts above operating voltage to 'start' operating so you may need a 17volt 2.5 amp PSU to get correct nominal 12 volt operation. I have used a 7 amp solar power controller on a mains electric Generator's 12 volt 'battery charging' output that was putting out 16 or 17 volts and was able to charge a sealed lead acid battery at 14.4 volts.

I asked an engineer at work about this. As long as the voltage matches, and the amperage does not exceed the limit of the charger, the device that is being charged will take only the electrical energy it requires. It won't hurt it. If the amperage of the device being charged exceeds the amperage limit of the charger, the charger may burn out.

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.

As long as you put 12 volts in to your batteries from your solar panels and draw off your batteries it will work just fine.

it should work like any other solar charger, just do not overcharge any battery.

I'm no Electrical Engineer, but this is what I have to offer: The charger I have is a Worx WA3737. The specifications for the charger are: Input: AC 100V-120V, 50/60 Hz, 1.5A. Output: 24V, 1.5A. Output DC barrel jack: Polarity = positive (outside = neg, inside = pos.) If your solar array can match the input specs for the charger, which I suspect you can't, you have no problem. On the other hand, if your solar generator can match the output specs for the charger, you should be able to charge the battery by some means other than the OEM charger, but the OEM charger may have components that protect the battery against overcharging, shorting, etc. In other words, you would have to have someone with knowledge of electronics crack open the supplied charger to see the circuitry and use/match that configuration for your new charger which is built for input from your solar generator. Of course, this would probably void the warranty, and should be done only by someone with a knowledge of electronics. Hope this helps.

Yes! It won't be overcharge on my home energy at 24hr 7d week all year round. It will be safe to charge with solar panel. It only charge on day time and night time none. As long it's a twelve volt charger to charge these batteries.

Sure, I plug it into a 12v back up battery I charge with a solar panel. But you could use an outlet.

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.

It will depend on how you plan to connect it to the charge controller and what the total amount of watts of panel you are connecting. So no, but you would need to check.

The short answer is, "Yes." You could connect the output of the solar panel to a 12 volt battery bank. The battery bank will recharge. HOWEVER, if you don't either monitor or regulate this, you will damage the battery bank from overcharging it. Specifically, if you could manually check on the voltage very couple hours, you could disconnect the solar panel when the voltage reaches full charge. or you could get a charge controller that is wired in between the solar panel and the battery bank. This inexpensive device will both optimize the charging current to the battery and will stop the charging when the battery is full.

This unit is a 10 Amp charge controller. That means the maximum input wattage it can handle is 120 watts @ 12 vdc. Your 500 watt panel would exceed this unit's rating. After my unit didn't work I sent it back and purchased a Morning Star, which was made in the United States.

Hi Miguel.. I don't know why do yo want solar battery charger with so powerful device (65w).. Maybe you know that sun never'll charge fully your wanted device.. I recommend you for this purpose this item: http://www.amazon.com/dp/B00E36E86Y/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=I3WDC9N7TJ9U&coliid=I9MHGSUOSV86A It has output voltage as you want (19V and max 3.5A of current).. I think it will helps you..
