Can I hook up the input side to the 12v output of another solar controller?

Thank you for your question.Deltran, the manufacturer of Battery Tender products doesn't recommend using two charge controllers on the same line. There is no need to have one charge controller in line with another. Make sure you use a charge controller rated for the size solar panel you have. NOTE: You can use multiple solar panels to charge a battery or battery bank and each panel can have its own charge controller. Just don't put the charge controllers on the same line.Thanks again for your question

It comes with mc4 connectors on the leads. I know it shows all the other wires in the picture but the newer panel just comes with the 2 (-) and (+) leads. Yes, you will need a solar controller if you are hooking this panel to a battery. The controller regulates voltage into the battery to prevent overcharging and a good controller will automatically disconnect if the voltage gets too low.

The whole point of this type of controller is to take your solar power of any voltage up to 48 volts (in this case) and output the proper voltage 12 or 24 volts to your batteries. Your panels do not need to be 12 volts, they simply need to fit in the specs of the controller which is a 48volt maximum input voltage. It will then regulate your output voltage to 12 or 24 volts, whichever you choose.

I would wire them as Anthony Gomes answered. Keep in mind the high current draw possible with a fully loaded 2000 watt inverter on the 12VDC input side. Use the shortest cables possible, and large enough to handle the high current, with good quality, secure connections.

I don't know if you would want to put that kind of power through that small a cord. If Goal Zero says it can accept that much power through there I would say you can wire up your own but mine did not come with such an adapter. The charge controller on this panel puts out 10 amps at 12volts that alot of power. The wires that came with mine seem to be much thicker that what i see on the goal zero page for connectors.

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.

This may work, only if you can install isolating switches. Then you can select solar, or mains charging, or on-board ac with the inverter .I don't know if the solar charge controller can be hooked up with the ac charger in common. I can try it. Best to be careful, so there is isolation between the power sources.

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.

I have 40 amps of power so I have 2 controllers tied parallel to my batteries. Yes, you can use two separate solar arrays connected to two controllers. Just make sure that your solar panels stay under 30 amps per controller.

So long as connectors end in 12 gauge wire to plug into controller. That's all you car about. You MUST plug the 12 volt connectors ( connected to batteries ) first. If you plug the solar panels into controller first, you WILL blow the controller . OK!!

I believe you can, but that doesn't mean that you should. Making the controller to all this conversion will severely alter its efficiency. There are charts in the manual showing just how much you lose, the more converting you force it to do. You're best off trying to get your panels bank output configured to be as close to battery voltage as possible.

If there are only 2 (12 Volt) panels; you could put both wires in the "solar panel" connectors. For more panels I would suggest you get wire nuts. Wire nuts allow you to connect many panels together (in parallel) without any wires slipping out. The kind of wire nut is the bolt kind, a slotted screw with a nut to crimp a few wires together for a tight electrical bond. Have a thicker gage wire going from the wire nuts (+ & -) to the controller.

its a 20 amp controller watts = volts X amps. So, 12 volts X 20 amps = 240 watts, so you can only hook up 2 - 100 watt panels.

Don't know, i have not used mine yet.I don't see why you couldn't.You may have to put a diode on the output of each one, i had to do that on 2 Astron 12 v power supplies years ago to get them to play nice together.Hope this helps.Mike

You can use this controller for 12v but there will be power clipping. The best controller would be the Outback FM-80 for 1KW solar panels charging a 12v battery bank. Thanks, ML SOLAR

The output of the PV panel are 2 wires. You need to provide your own connectors at the PV panel leads. FYI, after placing the PV panel under the sun, we used a voltmeter to measure the output voltage. Under no load, it produces + or - 20 volts. I'm not to sure if you could put some type of rheostat between the PV panel and your device that you want to power to limit the output voltage to 12 VDC.

That will work just fine. Just make sure your solar controller is rated for at least 10 amps and preferably 15 amps just to be safe.
