I would be more inclined to get a single outback charge controller for a little more money than spend on 2 of these controllers.

First, I bought one to keep a deep cycle battery charged up. Second, I would not use the 160 watt panels as they would not be cost effective (you would probably need lots).Instead look at the 250-300watt panels. As to the #, it depends on how much power you consume, and how much of that you want to generate, ie, 5-10KWH per day.

Input wattage at 24v is 1000w max so you can use only 3 of your panels in series...900w@24v.

you have to look controler . to see if it can handle 46volts . as most 24 v system . handle 32v . are you sure you not have series them ? is this unloaded voltage ? even that seems high as mosr are 42 v . most charge controler have a 28 .2 voltage full charge cut off . it in equzation mode 32v . this why most panels are over rated . in watts , good rule is take away 1/4 . so a 1000 watts realy put out 750 . a mppt control helps by 30% .

lets say you have 6 - 100watt panels (20 volts and 5 amps). if you connect 3 sets of 2 panels in series then connect the sets in parallel - you would have 40 volts and 30 amps. Depending on your efficency of your panel you could exceed the specs some of the time. If a working controller really matters to you then you might not want to find out what happens when exceeding specs. But using a combination of series and parallel you could stay within specs. Just remember that a series connection will degrade to the lowest panel. You may want to have the Remote Meter LCD Display (MT5) for Solar Regulator with 2 Meters Cable to monitor your system. Hope that helps. lets say you have 6 - 100watt panels (20 volts and 5 amps). if you connect 3 sets of 2 panels in series then connect the sets in parallel - you would have 40 volts and 30 amps.

More important than the wattage for this system is the voltage. You need to make sure that your panel puts out a voltage that's in the range of this inverter. This inverter operates from 10.8-30v, so in low sun when you're below 10.8v it will not operate. Conversely, if your panel puts our 30v, you will be putting to many volts through this inverter in direct sunlight. Also remember that it is a 600w peak inverter, so if you put 3 200w panels on it, you're operating it at full peak efficiency. I try to keep my 600w inverters at 540w of panel or less. This increases efficiency and also extends the life of the inverter. When you do expand, you have to decide whether you will wire your panels in parallel (to double the wattage), or series (to double the voltage) If you want to wire in series, you need a bigger inverter, if wiring in parallel, you can only really safely put one more 200w panel on this inverter. Hope this helps.

I use a 20watt panel and a voltage regulator. If you have a battery,you will need a solar regulator.

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.

A lot more information is going to be needed. What battery voltage are you going to be using, how far of a run, do the 100 watt panels have mc4 ends? The questions could go on for days. This has standard screw type terminals, so all you need to do is strip the copper, stick it in its hole, and tighten the screw. Hooking up panels can be a very different task if there are not mc4 ends. Then you will need a water/weatherproof junction box to combine the panel terminations, and then run a single line from where the panels. Your question is far too open ended to even try and answer. Be more specific

You need to connect the panel with solar wire connectors like the MC4. You can connect to several batteries as long as they are connected with the correct voltage ie 12 or 24 volts depending on which way you go with the charge controller. Connecting 12v batteries in parallel will give you 12v. Go in series and you get 24v.

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

As default setting, it will be 3pc 100W panels. And we can customized as your request. It can be up to 600W max, and it need to add 75usd

I would run anything above 5 fared, You are running 4600w a 3 is too low, Usually 1 fared is equivalent to 1000w aprox.and if your lights are still dimming, I would get a better efficient battery, I hope this is helpful.

Did you mean the *250 W panel? If this is the case, then yes this panel is rated for 12 or 24v. However, in order to charge 12V systems you would need a controller that is suitable to charge enough power at 12v. For example, if you are inquiring about our 30A PWN, then the rated specs mention that at 12v is 360W so technically you would be able to use this panel with this charge controller. Be mindful, however, of the fact that PWN step down voltage while MPPT models utilize virtually all the power initially started by the panels.

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.

3 batteries should do it, but to be safe 4.600 watts of panels to be safe. In theory you should need 2, but real world use is what im going by.
