I have my 12 volts going from my batteries out to my inverter to make 120 Volts AC. Do I put these panels in series or parallel to my batteries?

you should not connect these panels directly to your batter bank. they should be connected to a charge controller and from the charge controller you connect the battery bank. depending on the charge controller you would then either connect your inverter to the battery bank or as on my controller there is a lead that can connect directly to a load such as an inverter.....hope this helps. I'd recommend researching charge controllers so that you keep your batteries in the best condition possible. I bought my controller from http://www.windsun.com/

If you have a 12 volt dc input to 120 V AC output inverter then you would want them in parallel. That will give you about 18V to the DC input of the inverter. If you were to put them in series the you could have up to 37.4 volts DC going to your inverter and if it is a 12 V DC input inverter that could be bad, depending on the over voltage protection offered by the design of the inverter.

These are 12v panels. Unless you have a 24v mppt controller they should be parallel ( suggest to a combiner box ) feeding the charge controller which maintains the battery / bank state of charge. If these are your only two panels suggest a 20 amp (minimum) charge controller.

I bought two panels, have not installed them yet. Starting out with 4 batteries @ 100 amps, plan on going to 8 and adding two more panels

Depends on the voltage that you want to set up your battery for. A 12VDC battery, you can get away with 2 safely, 3 pushing it. For a 24VDC battery, you can handle 5 panels. You need to include all information in the question for a definate answer, but this is what you wanted.

Contact manufacture of your panels on what the output of both panels would be relative to your Volt/Amp requirements. It has been many years since I used Ohm's law! Good luck! (my connectors are still in the bag, as I had the same question,I received no response when I made my inquiry)

Your batteries are hooked up in series so you end up with 12 volts (one batteries positive to the others negative. Think of two flashlight batteries end-to-end. Connect the panels in parallel with the circuit. Your motor home runs off the batteries and the panels keep the batteries charged.

If this is an isolated unit you will need batteries and the proper cables. I daisy chained two 12v car batteries (720 CCA) together. I used 12 gage stranded wire (positive and negative) designed for car audio and soldiered the ends. I squared the ends soldered ends so they would fit properly into the solar charge controller. If you want AC power as I did I ran two more 12 gage wires (positive and negative) for the inverter. I hooked up a 1200 watt power inverter with 12v USB and other power options. This is an isolated 120v AC system and will run several lights, TV, radio, etc.

That depends on how much current draw each of your "panels" is. If the total current draw is greater than the safe output of this device than you need to get another transformer. If each of your "panels" is 12V and the current for each added together is less than 2.5A, than you would just wire the three "panels" in parallel.

The grid tie hooks directly to solar panels, you do not want to go through a charge controller nor do you want to hook to a battery bank. Using this small inverter I am assuming you have a twelve volt system, make sure you do not exceed the 250 wattage or you will fry the inverter For a little more money you can get a 500 or 600 watt inverter, I have 6 600 watt inverters that have been working great for over a year. I have 3 185 watt panels for a total of 545 watts on each 600 watt inverter, It is best to stay a little under what the inverter can handle

Batteries don't damage the inverter if they are connected the right way, you can have 1 battery or 20 batteries on your system, more batteries will only give you more backup time without hurting the inverter

inverters put out 120 VAC. I'm not sure what you are asking, it you are trying to power a 19 volt or a 24 volt device you don't need an inverter as it will be way over-voltaged. The inverter converts 12 VDC to 120 VAC.

The kit assumes you are putting all 4 panels in series and close to one another all in a row do that the short cables on each panel connect to each other. If you want to do two banks in series and then parallel, you wil need additional mc4 cables. Also if you are not putting the panels adjacent to one another you will need some mc4 cables to jump the gap. Otherwise you only need a pair of 4awg (or so) wires from the MPPT to your battery bank to charge them up. Then you can also get an inverter to run off your battery bank for AC outlets.

Hello JD, I am assuming this is being set up on an RV of some sort, so yes you need to set up as a 12V system. No doubt 12V is the input required by your inverter. The voltage set up is determined by what is being run off the batteries. Hope this helps.

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.

If the panels are less than 50 volt panels and are a long way from the MPPT then wire them in serial and hook them to the panel input on the MPPT. If not parallel them into the MPPT but use higher gauge wire. Always hook battery first to MPPT

I think the manufacture should clarify this issue. four wires from one battery bank or two wires from each of two separate bat. banks or can you use a jumper to connect the the studs on the inverter ???? {buss bar}

The batteries do not damage the Inverter if they are connected the right way at the correct DC voltage, you can either have 1 battery 2 batteries or 24 batteries its the same for the inverter, more batteries will give you more back up time but it won't damage the inverterThanks

Dear customer, you will need a branch connector if you want connect two panels in parallel. You can find the product here:http://www.amazon.com/Branch-Connectors-Connector-Solar-Panel/dp/B00BCWRB48/ref=sr_1_2?ie=UTF8&qid=1376241228&sr=8-2&keywords=MC4+Branch+connector You will also a Adaptor cable from the MC4 branch connector/MC4 connector to the charge controller. The length is to be decided by you. Thanks.
