Does the input and output voltage have to be the same? 24 volt solar panels with 12 volt inverter and batteries

I probably will not be much help here, yes they should be the same. 24 Volts in, 24 volts out. My Xantrex did not hold up however, and caught fire within 1 month. I now have a MidNite Solar Classic MPPT Charge Controller - 150V, and it is performing great.

i used 12 gauge from the solar panels to the controller and from the controller to the batteries i used no 6 awg i already had here The no 6 is probably overkill i wouldnt go any less than 8 from the controller to the batteries what is your battery bank at least 24v i hope

Either your voltmeter is defective or the solar panels are. Their output should be close to each other assuming they're getting the same amount of sun. 5 watts @ 12 volts should be about 0.4 amps.........voltage output under ideal, sunny, conditions should be in the 10 -14 volt range depending on temperature and amount of sunshine. I assume the wire lengths are the same for each, otherwise the longer the length the lower the output.

Because the voltage is 40 volts, you need to buy a voltage controller that accepts input for 24 volt or 12 volt. and the output for the battery will be 24 or 12 volt. The voltage controller will automatically detect the input voltage of the solar panel and will automatically detect the battery voltage. I have purchased two of these items on amazon. However, One seller was in Shanghai and the other in Hong Kong. you can get 30 watt or 60 watt. Blue Solar was the name of one of them. I did get both delivered after a while.

If your solar setup is designed to charge lead acid battery's wired in series for 24V, then yes. You will need to adapt your charging setup to use the same type of adapter that plugs into the side of the pack.

Yes it will I would wire your panels in series for 24 volts to the controller for best results and you bankroll have a 12v battery bank

The intended purpose of this device is to directly feed the power off the solar panel to this inverter with its 120 vacpower to the grid. If for any reason you come off the battery the voltage to the inverter must be at leastthe minimjm dc input voltage of the inverter, usually around 24 vdc. All in all I dont see the inverter workingoff the 12 volt battery.

It only works for the described voltage. The unit set for 22-60v is designed to be used with a series system of 12v panels so that the voltage rarely drops below 22. If you have a simple solar system (12v) then you would want to get the inverter with a lower operating range.

As long as you are producing 24 volt DC and storing it in a battery bank, you will be able to draw power from the battery bank and produce the 120 VAC house current. Not for a direct hookup from the solar cells to this or any other inverter.

Val this charge controller can only handle a maximum of 500w of solar for a 12v battery system, or up to 1000w for a 24v battery system. Since you are planning to use 3 x 250w, you will need to wire those batteries in series for 24v, and get a 24v inverter. If you don't want to go for a 24v battery configuration, and want to stick with 12v, then you will need to drop a panel and just go with 500w, or you will need to use an additional controller (controller 1: 2x250w, controller 2: 1x250w or 2x250w).

Yes it is fine. Most solar panels have or need a charge controller because they put out 24v. This panel has an integrated controller, and will automatically adjust to a 12v (or 24v) battery system.

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.

I see its states 12/24 volts.,100volts, woow that's a lot.,,yes Pv power refers to the solar panels as far as I understand.,i have a 12volt system.,with one 100Watt panel.,you have 24volts, so what are you confused about. you have another 76 volts to go before you could have problems.,,,LOL...Hope this helps.,we are all learning.,,

I purchased this after reading the other responses and can confirm. I'm using a single Solarworld 250w panel (24v) with two 6v Sun eXtender batteries (wired for 12v). Works great.

yes the voltage output will vary with the amount of sunlight. I have my panels setup to produce a max of 36 vdc charging a 12 vdc battery bank. your charge controller needs to match your projected final system capacity, if there is a possibility of adding on later. I have a mix of 144s and 88s

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.

Yes you can hook them up together in parallel and the voltage will remain the same but the amperage will be 4 times that of one panel. You will definitely need a charge controller with what is going to amount to 80 watts of panel input to the battery. It might be helpful to know more specifics about what you plan to do. If you want to just keep a battery up this is far more panel than you need. If you plan to use the battery daily to power things than 80 watts may or may not be sufficient depending on the size of the battery, the wattage/amperage draw of the loads, and how much daily sun you anticipate. There are a lot of variables. You will also definitely need fuses for fire safety. Hope this helps. BTW, it might be cheaper to buy a singe 80 watt panel as opposed to four 20 watt panels.
