Would there be a problem connecting a 30w and a 100w solar panel to this controller?

That should be fine assuming you are hooking the panels in parallel +to +, - to -. So 130 watts / 18v (typical output for "12v" pannels)= 7.22 amps

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!!

Yes- I have connected a 240w panel (30V @ 8amps) and also two 135w panels (total 35V @ 3.8amps each) and it works fine. The limiting factor that may cause the confusion is that the maximum output is 240watts (12V @ 20amps) if you are connected to 12V batteries. In my case, I was connected to a 24V battery bank and was dumping about 17amps at 26volts into the batteries when I had all panels connected (the 240W + 2x130w). For the money the controller works well. If you connect to 12V battery; 240w is maximum; if you connect to 24v battery you can get 480w. It doesn't support over 32 volts, so you can't use a 48V battery bank.

I have six 100 watt Renogy panels wired for 24 volts. The meter that came with this controller reads almost 40 volts. It varies from 30-40 volts depending on battery state of charge (I am using six deep cycle batteries...12v). It works great. Additionally, I have pulled 34 amps down from the high sun which equates to around 815 watts. My unit has NEVER shut itself off. When the batteries are fully charged it will still provide power to your accessories. I am using an DC-AC inverter...so, it really doesn't matter.

The 2 Grape Solar panels put out about 62 volts and 16 amps and this controller will handle 100V and 45 amps so you should be fine.

Yes, it will except 30 volts. The open circuit voltage of your panel will exceed 30 without load and cause a fault. A 12 volt battery will have to used since this controller is designed for lighting after dark. Mike D

I used it on 4 100 watt panels and it worked fine. I did replace it with a MPPT controller because I got up to 30% more from the MPPT controller.

I have not tried this and wonder why you want to unless you have too much power for one. They do make a controllers that works up to sixty amps. I don't know how you want to wire this. Using separate panels is the only thing I can guess. I use my meter every day to read the total amps going to my batteries and the voltage at any given time. The lights on the front of the controller tell you most things about the system but not the voltage or the current. The voltage tells you how close you are to a full charge. If you have two sets of panels you would need two controllers with two meters. Hope this helps. I have not tried this and wonder why you want to unless you have too much power for one.

It is very large in size. On board storage might be an issue, I'd check the specified dimensions carefully with this in mind. I have mine connected in series to 2 other 12V 100Watt panels and that setup is working just fine. It is pushing the towards the upper limit of input voltage that my MPPT controller can handle though.

So long as the supply can handle the amperage, yes. One unit that I received came with a pigtail (the one that included a light strip but no power supply), the 'controller only' did not.

I have had four one hundred watt panels hooked up to this same charge controller for nearly a year and it works fine. At first, I had them hooked up with the panels at 12v and the battery bank at 12v, then I switched the hookup to two sets of two panels in series to put the panels at 24v with the battery bank remaining at 12v. I get a little more power out of the panels this way because a lower amperage means a smaller voltage drop between the panels and charge controller, even though the wattage from the panels is the same. It works fine. With an MPPT controller, the voltage of the panels is not dumped directly into the batteries so you can hook it up either way. If you hook the panels in sets to reach 24v, then your only limit is the 30 amps to the battery bank. Anything above that is simply lost.

According to the directions you do not need a charge controller for a 30w panel on this unit. Larger panels would require a charge controller.

I have two 275 watt panels hooked to mine. I believe I have room to add another. It is a 30 amp charge controller. B

NO each controller can only handle 12 volt x 30 amp or 360 wattyour 4 panels will put out 580 watt If you use it in a 24 volt system it can handle 720 watts but it has a max input of 30 voltsso 2 controllers for your setup or get a higher amp controller if you plan to add

The solar controller and generated can be connected to the same battery in parallel and not have any problems.I would only see an isolator or disconnect switch necessary if you wanted to remove your batteries and switch them with a different set or configuration.That way you can disconnect your panels while managing your batteries. This is good for preventing your charge controller from getting damaged.Let us know if you need further assistance.Regards,AW

I believe you are asking if you can mix panel types with this controller....no. You will need the MPPT type Morningstar controller.
