How do I wire this into my 40W (20 V 2A) solar panel/12 V battery charging system? I also have a charge controller in this circuit.

Connect red leads together. Connect black leads together.( the thinner red and black leads are to power the meter itself. Even a 9v battery could be used to make this portable! ). Make sure you use a voltmeter to keep track of the polarities throughout this procedure. ( Might as well let the panel power the meter too). Now connect the double red leads to the + output of the panel and the double black leads to the - of the panel. (The meter should come on and display the voltage at this point). Next connect the blue lead to the - side of the load, ( charge controller). The +side of the load, charge controller should be connected directly to the + of the panel. You also could connect this meter, instead to the output of the charge controller. Live by the code..... Measure twice, cut once!!! You can also use just the voltmeter part or just the ammeter part too. Remember the voltmeter is going in parallel to the panel and the ammeter is going in SERIES to the panel and charge controller. I tried to include a diagram below but it had to be in text format, hope this helped. +......................................................red(both)................................................................................+ Panel METER Load NEG ...........................blk(both)...... ...blu........................................................- Open cable from panel here^

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

Most larger, more powerful panels are 24-volt. A good charge controller will automatically step the 24-volt down to a 12-volt battery. I don't know off hand if the HQRP will do it -- it seems to say that it does, but you might want a more expensive controller, a MPPT controller. Also, if you have 150-watt+ solar panel, a 10-amp charge controller is too small, as you probably already know. You'll probably want a 20 or 30 amp.

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.

Frank, i have a Renogy catalog on front of me and don't see a 350 panel. This must be something new. And by 30amp charge controller I assume a PWM charge controller. Your panel can be 12 or 24v not both, unless this is something really new. You might try one of the solar forums or email Renogy support. Don't call tech support because i tried. Don't. Ok? Try Northern Arizona wind&sun or midnite solar forums. Also midnite solar has videos on youtube about everything. You should be able to charge a 12v battery with a 12v panel and charge controller-period. Unless the battery is no good. Put a voltmeter at the output of panel then the output of charge controller. Good luck.

You won't want to connect the panel directly to a battery, as it could damage or overcharge it. The panel itself only provides a voltage, you need a charge controller between the panel and the battery. The one I used (http://www.amazon.com/gp/product/B001HWQZNQ/ref=wms_ohs_product?ie=UTF8&psc;=1) is not currently available, but should give you an idea of what to look for. You want a controller that can handle at least 30 watts and 17.5 volts input for charging 12v batteries.

The charge controller should have two pairs of wires: one pair each for input from solar panel(s) and output to battery. There should be words or symbols indicating which pair connects to which device. The wires should be color-coded red, yellow or white (+) and black (-). A 20-watt (also called 18 watt) is good for charging 1 cellphone and 1 tablet PC at the same time in full sun by connecting outputs to a female 12v DC recepticle and then using a male 12v DC plug with 1 or 2 USB recepticles. Do not expect more from this unit. I live completely off grid; so, if you need more solar power, ask at alolmstead at g m a i l d o t com.

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).

You would have two wires (I use #10 copper braided wire) coming from solar panel to controller then two wires from the solar controller to battery.

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.

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

Do you mean your solar panel puts out 18 Watts or 18 Volts? The 10 Amp Solar Charge Controller is designed to charge 12 Volt Deep Cycle Batteries. If you only have a 18 Watt Solar Panel recommend upgrading to a larger panel.

Look on the adapter and it will tell you...I believe it is about 20 volts...you could definitely make a solar charger...the other option, one I use, is to use a 12V to 120 adapter and then can plug any 120v appliance in to the standard outlet...obviously within the wattage of the solar panel and adapter...and it will exhibit some loss...typically about 20%

No, I think the generator inside the unit is set to generate 12V. The controller that goes with this system is also 12V so unless there is a controller that can convert to 24V, then you may need to find another way to convert the charge. I 24V system is more expensive though? FYI.

this charge controler will work for a 24 volt system. that being said, you did not state what you are doing with it. i would assume you are charging batteries with your solar panels and that you intend to get a lot more in the future. if this is all the panels you are going to use with this controller, it is way more than you need. since you are a first timer, i would urge you to consult with someone in your world that knows solar and electrical hook ups. do this and save a bunch of time and money, and your safety. best of luck!

The short answer is: A pair of alligator clips to connect the wires to the battery. If you or a friend have any mechanical ability at all, it is easy. You get 40' of wire that becomes 20' because you run two conductors, a positive and a negative. You will cut the desired length of wires to run from the panel to the controller. The wire remaining will be used to go from the controller to the battery. The terminals on the panel, the controller and the battery are clearly marked as to what goes where. (I used a piece of red tape to mark the hot (positive) wire at all ends. (the wires are all black.) This system is superb. We use two batteries and have all the power we need in our RV. (Lights, pump, tv, computers.) We are thrilled with it. (The price is unbelievable. $600 in RV stores) If I can be of any other help please don't hesitate to holler: Ivor ivorthomas316@aol.com

I would keep the configuration the same because you will above 13 volts to charge the battery. If your looking for amperage in series, it's best to have a power capacitor wired on the 30 amp solar controller battery input side, and the output on the capacitor to the battery with a resettable 20 amp fuse on the red cable to the battery. The capacitor depending on the Faradays you pick, will act as solar storage and help the backup battery recover fast if your running an AC Inverter on the battery output cables. Remember these panels are only outputting at 35 watts, so the amperage is low and need capacitors for storage.
