Can I add a 12v 10amp charger to my load? Should I connect it to the solar terminal, the battery or load?

The charger should be connected to the battery. Quote from the manual, "Auxiliary Generators: Engine generators and other sources of power may be connected directly to the battery for charging. It is not necessary to disconnect the ProStar from the battery. However, do not use the ProStar to regulate these other sources of power."

No, You can not add another charge controller to the load side of the Prostar. You need to connect directly to the battery.

50 watts from this unit is assuming a bright sunny day. However, a 12V / 9Amp Hour battery should be able to fully charge during the day....This will give you 3-4 hours running your 3x10 watt lamps during the night. Make sure you connect your battery to the Solar Panel via a charge regulator.

Roger- on mine, you connected to the terminal for the transformer. Then the circuit board monitors how much voltage the battery receives. The GTO website has a very good technical advice page that explains how to connect solar or 110/12v. You can also call and get a live person to discuss also.

i can take a guess. i have never come across an 1120amp/Hr battery before, unles you have a few in parale. you will need more than 12 volts, about 13 to charge that battery. most likelly about 12 hours with no load on the battery. you'll need a solar panel that's over 140 watts to charge those battery's. hope this helps. GOOD LUCK .:-)

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...

all you need are the cables to connect the two terminals. battery will need a charging source at some point but inverter and battery alone will run until battery reaches 10.2 volts

You need a charge controller. I bought this one http://www.amazon.com/gp/product/B008I0IZ7O/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1 , but I had to cut the wires on the solar panel to connect to the charge controller. You can get adapters, but I'm not sure what those are called.

I don't know about that one. I've always hooked up the 12V battery directly to the solar charger. A lighter adapter didn't come with the solar panel.

Can't help on the solar panel. I have used the 12v option off of my house batteries. The unit worked fine

That depends on what you want to use it for. For charging a battery I would use a separate charge controller. A 12 volt panel can put out 20 volts in peak sunlight which would over charge and damage your battery. For something like an DC attic ventilation fan you can just run it direct. The fan will spin faster or slower depending on the amount of sunlight / voltage, which is not a problem.

This is just a trickle charger to keep the battery charged when not in use. Do you have a volt meter? You can check to see if is working by hooking the red wire of meter to red wire on the solar charger and blk to blk put it in the sun you should get more than 12v.

The instructions doesn't give enough explanation. I called the company for my inverter and asked if solar is compatible with their inverter hooked up to the charge controller. They said to keep the inverter connected to the battery. The only thing I can think of is using a 12 volt light or a small apliance could be connected directly to it instead of using the battery power. If a 12 volt light is connected directly you are taking advantage of the solar imediatly. If the same light was connected to the battery instead, the charge controller doesn't let the solar charge the battery until it drops to a certain voltage. So solar panel isn't being used to its full advantage.

I think that if the input voltage of battery is 12 V and the shapes of inlet are compatible, then you can use this solar panel directly.If the input voltage is not 12 V, the you can charge battery by car adapters.And I want to suggest that you should disconnect each other after charging battery. Because some one said that the panel discharge the battery while the sun is down.

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

No you cannot. The panel/charge controller cannot run any loads without being connected to a battery. The energy supplied to the load must come from the battery. There is one exception I have seen. There are some 12V water pumps that will run directly off of a solar panel without the need for a controller or a battery.Renogy Tech SupportSR

I just got my charger, used it at a dry campground in my 16 ft trailer. Plugged it into the 12 volt connection inside the trailer, placed it by a window, it kept my power up. I also set up a connector from my battery and had it come out by my elec cord. That way if I am in shade I can connect from outside and have the 10 ft extension to sun. I do not have outside access to my battery, it is under a cabinet.

You may need a regular battery charger with instant start mode. I have one of those too, but I prefer the battery tender even if it takes longer, if I can wait. I also have the Tender unit w/a solar panel trickle charging one of my boat's batteries right now. Pete
