Is it possible to connect 4 X 250 w 24 V in series to have 48 V tension to lower the amps (1000/48) and then have The tristar 45 A turn it into 12 V?

Yes it is possible to work the way you describe, however, you want to be aware of code and over-current issues. Depending on the exact location, for example where there is higher solar radiation, you could have over-current.

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

Power clipping is the term use to describe when a inverter or controller does not convert the same amount of power as the panels produce. The TS-MPPT-45 will only manage 400 watts of Solar power regulated to 12V. The remaining 600w is lost potential power. SO, you need a larger controller. We have never had an Outback returned for any reason but in any case the Outback FM-60 is good up to 900w of solar and the FM-80 up to 1250w or solar. Reduced to 12V.

Not sure of the question?4 24v series panels will put out 96vdc.Be careful and remember that 24v is nominal output, the real max output per spec can be 33vper panel.So 4 24v panels in series can generate a max voltage of 132vdc.I personally add in at least a 20% margin over spec on all calculations.Yes, I believe you can run higher voltage/lower current at the array and the Mppt can auto convert to 12v.You might check the specs for max current/voltage/power and also the conversion efficiency.

It is a 50 amp supply and will provide that at 12 volts continually. Your amp needs 120 amps. Oh those specs imply big external capacitors to deliver 5000 watts. It can only take in 1440 watts (120 amps x 12 volts) and they don't create power.

If you operate in a mixed 12V 24V environment, it's fairly trivial to add a 12V or other adjustable voltage regulator for that purpose. http://www.amazon.com/Converter-Regulator-Voltage-Reducer-Step/dp/B00AO0PCMW/ref=sr_1_2?ie=UTF8&qid=1362772728&sr=8-2&keywords=voltage+regulator+24v+to+12v

yes you can u can. google a connector that will hook 4 together.4 would only be 60 watts so 1 controller should handle it.Although u should be at least using 2 deep cycle batteries so u can pull a load up to 7 amps.

No because I believe it is only 12V DC Input you would have to get a model APS2424, APSINT2424 or APSX3024SW which are made for 24V DC Input Power

36 watts is 3 amps on a 12 volt system. Depending on how many you use, you could run 4 on a 15 amp fuse/ switch.

Yes I up graded from a 45 amp to 55 amp but there might be a short in your 12 volt wiring if your converter keeps going out

Amps=watts/volts. So 250w/24v=10.4 amps. This is considering full output of the solar panel and no loss through cabling. So to be safe you can run three solar panels More than likely you can get away with four, as you will likely never see a full 10 amps output.

Are you running 3 full standard 16.4ft, 150 led rolls/strips equaling 49.2 feet? Each strip is 3 Amps witch means the power supply must be 12v 9 Amps minimum. If you are over 49.2 feet you might need a stronger power supply or add another amplifier to the run. The amplifier output reads 12A but I've noticed that all diagrams never show more the two strips per amplifier. Good luck

Assuming each panel might put out 12 amps at full sun, 6 x 12 = 72 amps. The meter literature says 100 amps rating, 50 amps continuous. Problem is the wire gauge is 14 - so you can't run much wire length (less than 5 feet or 2 meters)at that 50 amps. Borderline. I don't think this will work for your application with that many panels/watts/amps.

watts divided by volts will give you amps, however if your input drop below 10v you would need to readjust the blue pot screw same if it goes above 11.3I wouldn't there is a good universal on this site with a voltage select and multiple output adapters

For 36V, the charger will only supply 12.5A. I believe it's the same for 48V.

This will be able to handle of total of 72 watts or 3 amps (72w/24v). If you are worried about overloading the circuit add a 3 amp fuse.

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).

Not directly, but (just as Ron Coleman suggested) you can using something like this: http://www.amazon.com/Schumacher-PC-6-120AC-Power-Converter/dp/B0012BL8LG/ref=sr_1_3?ie=UTF8&qid=1421162514&sr=8-3&keywords=5+Amp+AC+to+12V+DC+Power+Adapter

Sounds like you would be underpowering the sub, by a lot. IX402 is 40W, BP1204 is 250W-300W.

Hi Cheryl. I don't know for sure if a 48v unit can be used for a 12v system, but my guess is that it can't. I say this because I know that units are also made for 36v systems, so I suspect that a unit must be specific to the voltage of the system.
