I have 3 100 watt panels with a 12v battery using PWM 10a charge controller and a Thor 2000 watt to 4000 watt peak unit. Could a mppt work better?

Call morningstar and ask them. I have one heck of a time trying to figure it out. Www.morningstarcorp.com215 321-4457

Mppt would work better because it does peak power tracking of the solar panels. This provides a significant efficiency increase in the power output of the solar panels. There is more information about it here: http://www.morningstarcorp.com/en/support/library/Trad-PWM-vs-TrakStar-MPPT-April-2013.pdf

MPPT is a little overkill. You need a 20A PWM controller like the morningstar ss-20-12V

I have used this to keep a 12 volt marine battery fully charged all summer and it worked well. I used a charge controller between the solar panel and the battery. This is the one I used.AGPtek® 30A Solar Panel Power Battery Charge Controller / Regulator 12V / 24V 30 Amp with PWM Type of Charging (Automatic Lighting Control + Time Functions). Of course, you can use any charge controller.

Hello, I am using (2) 250 watt panels with four deep cycle battery bank and it works great.

yes the voltage output will vary with the amount of sunlight. I have my panels setup to produce a max of 36 vdc charging a 12 vdc battery bank. your charge controller needs to match your projected final system capacity, if there is a possibility of adding on later. I have a mix of 144s and 88s

Power (watts) = E (voltage) x I (current in amps), so 12 volts x 40 amps =480 watts. 480 watts/250 watts/panel = 1.925 panels. With the panels only producing 250 watts in perfect conditions, and with the efficiency factor of the panels multiplied in, plus the loss on the wire between the panels and the charge controller, it looks like your charge controller should be able to handle 2 panels, barely. Only 1, barely, if you run at 24 volts.

I use a single panel and a wind generator, it is PWM, not MPPT. it is a Rutland HRSi and only takes 160 watts. I have not answered your qustion but i hope this helps.

Battery in question is 100ah x12v = 1200 watt hours. This panel can provide 144 watts per hour for battery charging purpose. Rule of thumb batteries should not be drained more then 50% or maximum 80% otherwise battery life will be compromised, so we will consider 600 watts to be charged. 600 watts divide by 144 watts = 4.16 hours. Since this panel is 24 volt and your battery is 12v - MPPT charge controller is highly recommended. MPPT charge controller can accept higher voltage (24~36 volt) from the solar panel and charges a lower voltage battery (such as 12v). Morningstar SS-MPPT-15L will be a good charge controller for this setup. Battery in question is 100ah x12v = 1200 watt hours. This panel can provide 144 watts per hour for battery charging purpose.

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!!

31.666 amps is where you are with your 4 panels. I agree with AT... You need a larger charge controller or research using multiple controllers.

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.

If you go to 1000 watt you can charge a 12v battery bank then 2000 watt for 24v battery bank with this charge controller

Yep. Limit for a 12V system is 260W. As it's mppt you can run up to 150V and it will break down to feed the 12V converting the excess voltage into amperage so you have to consider limits on that end. I've run a pair of 145W in series but it would clip the power at 261W. Presently have a pair of 100W in series feeding 36-38V no problem charging 2 225Ah 6V batteries.

You should look at running 2 - possible 3 100 watt panels, if an upgrade for future look at 10 gauge panel wire, it seems your running 12 volt, but your inverter and charger will depend. I've got a 40 amp 12/24 charger but batteries will run at 12 bought in a kit with 6 100 watt panels but told to only run 5 as my 60 amp also takes 1600 watts if at 24, but running at 12 so 800 watts mix up and I was sent a 12 both are mppt, you can probably run 5-6 100 watts if you have 2/ 25 amps combined, if not mppt they will keep charging but at a lower rate will destroy your batteries if not in use all the time, go with 10 gauge wire you will be happier.

Hello, Since this unit is 50 watt you can use at least a 5-10 amp controller. If you want to add more panels in the future you may want to consider a 30A controller. Other than the panel you also need cables to run from panel to controller and cables to run from controller to a battery/set of batteries. Let us know if we can help with anything else. Regards, AW

No, Anything over a 5w panel and you want to run it through a charge controller first. You risk overcharging a battery (which will eventually kill it) if you don't, even 5w is pushing it unless its a 70ah+ size battery and it has a constant small draw from it (Like in a car where electronics are being run even when the car is off)

Yes you can connect up to 3 100 watt Panels is what I was told when I called Goal Zero with that question (888) 794-6250. Note the internal charge controller is 10 amp. For plug and go applications I use 4 bolder 30 panels equaling 120 watts output. I also connected the Yeti to a battery bank. The 120 watts is sufficient for two computers, DVD player, tv, and phone charging simultaneously.

If you connect four 10 amp solar panels in parallel the resulting output would equal 40 amps +/-. Realize that the output ratings are under ideal conditions. Cloud cover, sun intensity, location of the panels are some factors in output efficiency. The output voltage can exceed 12 volts which is one reason a charge controller is needed. Make sure your charge controller is rated to handle your combined output.
