I have a 5V (9A - 45W) solar panel. Does the charge controller work with 5V input?

I received an Amazon message requesting an answer to your question; problem is, I have no idea. It works OK with 12 V DC.

I'm not sure exactly what you have. Nearly all solar panels are set up in either 12 or 24 volt configurations for normal battery charging. Especially if it is a 9 Amp - 45 Watt Panel... I have a 45 Watt panel that at best only pushes 2.7 Amps and fluctuate between 10-17 volts depending on how much sunlight. At 5 volts you are probably talking about a USB charging panel for USB devices? If so your cell phone or tablet will have an on board charge controller... Ultimately, I think NO... this charge controller will not work for you. It needs either 12 or 24 volts into the controller to tell it how to charge the battery set up... Also, it has a non replaceable fuse inside. So if you blow the fuse, like I did, you are faced with either getting a different one, or trying to replace the fuse some how...

The solar panel rated peak current is 5.7Amp. The charge controller 30amp is maximum system input the charge controller allows.

Yes you can however you will need a controller capable of handling both panels. Most small inexpensive charge controllers handle 7 amps or less. Two 60 watt panels will produce more than 7 amps on a sunny day.

One will need MPPT charge controller with this setup 45 Amp should be good enough for three of these solar panels. Morningstar is the brand we sell & support with these panels.

Yes BUT... You have to buy a charge controller that can "step down" the 36 volts from the panel to 12 volts for the batteries.Look at Morningstar controllers and or go to Morningstar's website to get the specs on an appropriate controller for your application.

I'm guessing that the solar panel is the "Source" and the charge controller is the "Load". If so, if the panels are indeed putting out 335 watts, and the voltage is 16.65V, you should be drawing 20 Amps. Perhaps it is a poor connection, or the charge controller is not allowing any current to pass through. If you have a standard multi meter, you could measure the current by allowing the red wires to feed through the meter. (be careful, many meters can't measure more then 10A, and if indeed 20A are flowing, that could burn out the meter.)I use my Watt's Up meter to measure drain from Li-Po batteries connected up to brushless motors and it works great.

You've probably checked on line, but this is a good site to referencehttp://www.chargingchargers.com/tutorials/solar.html25 milliamps is really small, and may not generate enough watts to bring the controller into play.I connected the controller to a largish solar panel, output approx 20 volts, for keeping my boat battery topped up.. the combination seems to work well at this level.Hope this helps.

That is only part of the reason to use a solar power controller. It also controls the charging voltage corresponding to the state of charge in the battery, just like a smart battery charger.

No. This item does not normally required charge controllers unless the panel is 30W or larger.

I think you need to check your controller specs, but I know some controllers may just shut off to prevent damage. Also note these panels are higher voltage which may not be compatible with your controller. I bought a charge controller that won't work with these because the voltage may go up to 45V on these panels. Now I run two of these with the Morningstar MPPT 45A charge controller. Morningstar has a calculator on their site that will confirm whether a planned setup will work with their charge controllers or not. I am planning on adding one more panel to my setup. The 45A MPPT charge controller can handle 3 of these panels. Good luck! I think you need to check your controller specs, but I know some controllers may just shut off to prevent damage.

A real MPPT charge controller can accept higher input voltage, so there is no need to branch together for the solar panels. The max input voltage for this charge controller is 100V, so you can wire them in series using thinner cable as the current is smaller.

Yes, The MPPT charge controller does the input/output conversion internally to provide the most efficient charge voltage and current. Mppt controllers are about 30% more efficient than the old type.

Sure, if your solar setup has a USB output and can provide the 5V that this device needs!

It is best to use a solar regulator (or solar charge controller). 3Amp or greater charge controller for 1 x 45Watt panel. You can find lots of inexpensive ones on Amazon. However, if you are just using it for a quick boost charge, you can hook it up directly to the battery. But, if you connect directly, you must monitor it to make sure it doesn't overcharge (cook) the battery. And, never leave it hooked directly (without regulator/controller) to the battery at night, because the battery will discharge into the solar panel.

I don't have any problems with mine when the solar charge controller is on, and it peaks at 28.5v. Same with my 24v backup charger (which puts out 27+ volts). It should be fine.

Yes, I hooked a 5w trickle charger panel to a 12v battery and it worked well. Might want to go with a 15w panel however- mine loses charge if I leave it on 24/7.

Hello Jennifer,Yes, the Guardian 12V Charge Controller will charge any 12V battery. The Guardian can handle a maximum of 90 Watts input. You can use 3 - 4 Boulder 30 panels with the Guardian to charge your 12v battery. Thank you for your interest - I hope we can help you - Denis, PrepareDirect
