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.,,

It is rated for 10 amps input and output. If it can handle 48 volts (which I don't know because I have a 24 volt panel) it will receive 48 x 10 or 480 watts (volts x amps equals watts). However, if you are charging 12 volt batteries it will only put through 120 watts. I ended up trading this in for a 20 amp controller because of this. I am very happy with the 20 amp controller.

This model will handle a maximum of 100 volts of DC output from your solar panels, so your 48 volts is well withing its limits. If your system uses 12 volt batteries, which is most common, and your panels produce no more than 130 watts of maximum power (260 watts if your electrical system is 24 volts) this controller will do the job well. This is a great little controller and I'm totally satisfied with it, and the price is very fair.

Looks like the max SOLAR INPUT VOLTAGE is 100vdc for the 1210RN model. The max PV input power is 12v 130 watts, and 24v 260 watts. The higher the voltage, the more efficiency. Since this manual is translated from Chinese into English, it is very confusing. You can have a 100 volt solar panel array, is what I get out of it. This is what we get for buying Chinese products. I can tell you it's still working great for me since I bought it earlier in the year. I have one 100w Grape solar panel that is 24vdc. The voltage on "12v" panels is all over the place. I think the controller will be able to handle that up to 100vdc with 12v out to your battery bank. Looks like the max SOLAR INPUT VOLTAGE is 100vdc for the 1210RN model.

I'm using this controller to charge a bank of 4 12 volt batteries and my solar panel is rated at 30 watts and 17.5 volts. It seems to be working fine but I don't know if the controller lists any maximum input voltage or not. One would think it would be capable of handling a wide range of voltage just because of the nature of most solar panels but that is simple logic and simple logic doesn't always apply.

Hello,If you are charging 24v the controller can support 3 of these panels.In 24v the controller can support up to 800 watts.Please let us know if you have any further questions.Regards,Austin WaltiRenogy Technical Support Rep.

Yes- I have connected a 240w panel (30V @ 8amps) and also two 135w panels (total 35V @ 3.8amps each) and it works fine. The limiting factor that may cause the confusion is that the maximum output is 240watts (12V @ 20amps) if you are connected to 12V batteries. In my case, I was connected to a 24V battery bank and was dumping about 17amps at 26volts into the batteries when I had all panels connected (the 240W + 2x130w). For the money the controller works well. If you connect to 12V battery; 240w is maximum; if you connect to 24v battery you can get 480w. It doesn't support over 32 volts, so you can't use a 48V battery bank. Yes- I have connected a 240w panel (30V @ 8amps) and also two 135w panels (total 35V @ 3.8amps each) and it works fine.

The solar panels will generate 27 watts when fully illuminated. All 27 watts are available via the "12 volt" plug (which appears to be the unregulated panel output, which is not 12v). The built in USB 5 volt power converter has a 3 amp limit, therefore the total power available to the two USB ports is 15 watts.

Your panels are rated between 5 and 6 AMPS at 18-20V. The Charger is designed to handle 20 AMPS up to 32V. It is also used as a timer to support automatically running an electrical output circuit.3 panels are within guidlines. Your maximum PV INput would be about 460W at 22V. You could add a 4th panel without losing much efficiency.

The panels can supply between 12volts to 30volts and above depending on the sun's radiation. However, for a 12volts system you need a charge controller connected between your panels and the batteies. This will give you the required 12volts to your system with no worries.Hope that helps.

Each panel is 130 watts and 17.1 volts output and 7.6 Amps. 17.1 x 7.6 = 130 When I connect thur a solar charger on a sunny day it can read into a battery 13 volts x 20 amps = 260 watts input to the battery charger

The Sunforce 60032 is rated for "12V" solar panels. These typically have an open loop voltage of around 21 volts, or so. It's interesting to note that a solar cell is a current, not voltage source, so it tries to deliver a constant current and raises the voltage up to a maximum as the load is reduced. Power output is voltage times current. In the open loop configuration (no load) the voltage is maximized but the current is zero. In the short circuit configuration the current is maximized but the voltage is zero. In both these cases the power output is zero watts. To draw power from the panel requires a resistive load so that both the voltage and current are non-zero. The Sunforce 60032 is rated for "12V" solar panels.

Their book specifies Max PV input power 12V/390W or 24V/780W. My PV output is max 18V at 21A. That is 378W (18 x 21 = 378) and does not exceeded their specs so I don't have any experience as far as exceeding the books specs. Going from a 12V to a 24V PV system will double your wattage without increasing your amperage however, in order to use that increased wattage without exceeding the 30A output current, you would also need to change to a 24V battery system. The output is rated at 30A regardless of the input voltage or amperage or battery voltage.

Hey Edwars O. Not sure. What type/sort of system are you putting together? 6V 12V? What are you needing to run, and for how long? What are your energy needs? I can't answer your question my friend without more info. I personally use the 400 watt system with another 100 watt panel. I match my batt bank so every 100 watt of solar for 100Ah of storage. Yes, it is over kill for just myself! I'm still in the learning processes if you will. The panels that come with this kit have zero issues with charging the batteries on cloudy days. I'm very happy with this basic system so far!!

I only tested the unit by hooking it up to my car batteries (two in serial for 24v DC) and it works. I suppose as long as your solar panels under the full sun won't exceed the the unit maximum input voltage ratings you should be fine. You can connect your panels in serial or parallel or in combination to provide the voltage within the range specified by the unit. Obviously it should work (producing power) during the day with full sun but voltage/current would tapering off (so as the power generation) when the sun goes down.

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.

The spec sheet rates the Tracer-3215RN for use on 12 or 24 volt systems. Max input from the PV unit is 150VDC @30 amps. Presently I am inputting 30 volts from my panel array @34 amps which is @ 1020 watts and I have been doing this for several months. My storage bank consists of 18 marine batteries at 12vdc. I have been doing this for several months and all works quite well. Hope that helps.

The higher the voltage the more watts you can charge and the smaller the cables need to be. Remember Watts = Volts x Amps so if you wanted 1000W at 12v the cables would need to handle 83.4A where as 1000w at 48V the cables would only have to handle 20.84A. The problem with having a higher voltage set up comes when you start looking for an inverter. It seems that a lot of the more affordable PureSineWave inverters are 12v.
