The renogy website identifies the 350 as 12/24V panel. Why won't it charge a 12V battery with a 30A 12-24 V charge controller?

Frank, i have a Renogy catalog on front of me and don't see a 350 panel. This must be something new. And by 30ampcharge controller I assume a PWM charge controller. Your panel can be 12 or 24v not both, unless this is somethingreally 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. Frank, i have a Renogy catalog on front of me and don't see a 350 panel. This must be something new. And by 30ampcharge controller I assume a PWM charge controller.

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.

you need 24 vdc battery you can get 2 12vdc deep cycle batteries and connect them together Negative to positive that leves a neg and pos open this will give you the 24 vdc that is comming out of the panels and your charger will need to be 24 -48 vdc theses panels out put at 30vdc

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.

If the panel puts out 24volts d.c. then you need a 24 volt charge controller. Many of these controllers can detect the input voltage (12 or 24 volts) and can automatically adjust to work with either.

It's made for a 24 volt charge controller. If you just have a 12 volt controller get 2 100 watt panels from home depot and wire them in parallel.

I agree with most all said here before. Get 2 12v batteries in series = 24v, or 4 6v and hook up in series but controller is best way to go to match your solar panel. Most quality solar panels will charge 12v and 24v. Get a volt meter and check it out as you go. A fuse is a must. Good luck

It needs a voltage regulator to keep from overcharging the powerpack. I have the cheap 10 amp ($15) controller. Output from this panel can exceed 20 volts in strong sunlight.

The panels can supply greater than 30 volts depending on sun. It is the charge controller (also a voltage regulator) that supplies the charge voltage of 12 or 24 volts depending on how it is set. The more voltage your panels can generate the better.

Your charge controller needs to be able to handle 48v input...Morningstar TriStar can, and the Renogy PWM 30 Amp w/LCD can also. Check out pvdepot.com and batterystuff.com-- both have good info for sizing your system correctly.

ZyPhReX, This chargers real ability is to convert 24V panels to 12V or 12V panels to 24V. The output amperage is based on the output voltage as far as I know. So this MPPT controller will handle 240w outputting to 12v. 480w outputting to 24V. I would recommend a ~250w 24v panel, this changer, at 12V. Or 2 ~250w 24v panels, this charger, at 24V. You can wire them in series up to 100v. Realize that 12v panels run at about 15v and 24v panels run at about 30v.Hope I helped.

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.

That distance is too long for the Renogy folding solar panel. The reason is that on the folding unit, the charge controller is mounted to the panel itself and the voltage loss from the charge controller to the battery over a long cable is too high. Most deep cycle batteries need 14.4 to 14.8 volts to charge properly in the bulk charging phase and the absorption charging phase. The last tenth of a volt is very important for charging. My solution was to remove the charge controller from the solar panel, mount it near my battery, and run a heavy cable from the panel to the charge controller. This reduces line losses because the panel runs at 17 volts on average, compared to 14.4 or 14.8 for the charge controller output. Higher voltage reduces electrical transmission losses..

Since the Controller os automatic Voltage sensing on the Battery Side, the answer is NO. The Controller will sense a 12v battery system and will shut down, as in overloaded. The Controller will allow you to hook up to a 24 volt solar panel but the max input into a 12v battery system is 390 watts (30 amps nominal throughput to the batteries).

I have had four one hundred watt panels hooked up to this same charge controller for nearly a year and it works fine. At first, I had them hooked up with the panels at 12v and the battery bank at 12v, then I switched the hookup to two sets of two panels in series to put the panels at 24v with the battery bank remaining at 12v. I get a little more power out of the panels this way because a lower amperage means a smaller voltage drop between the panels and charge controller, even though the wattage from the panels is the same. It works fine. With an MPPT controller, the voltage of the panels is not dumped directly into the batteries so you can hook it up either way. If you hook the panels in sets to reach 24v, then your only limit is the 30 amps to the battery bank. Anything above that is simply lost.

You need to buy a 12 regulator they sell for solar panels so it will not over charge your 12 volt batteries.

Is this a 24volt panel that is not outputting full power? If you hook the panel to the charge controller that is first connected to the battery and you get green light I would go for it.

I can confirm Renogy Solars answer (it'll work with either 12V or 24V battery banks). I use this panel with a MPPT controller and a 12V battery bank.
