Hi, Is this system work with: 2 panels of 24v and 300w each to charge the battery bank of 48v system.

If you have a total of 600W then yes, you just need to connect up the panels in series so their combined voltage is OVER 48V but under 150V. As long as the solar panels combined voltage falls between these range then yes it will charge it no problems.

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 link that you sent me is for the mounting kit. there are several panels. they are all 12 volt and range from 7 to 100 watt.I use the 100 watt panel to charge 2 12 volt batteries in a small camper. It works well.

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

Yes. You connect the battery with the charge controller. This is only for 12Volt battery. If you have 24volts, you will need to replace the charge controller with a MPPT one.

No. It doesn't work very well on the 48 volt system. My batteries are depleted before the diode lights are showing that it should be half charge. 12 volts probably would not even light up one of the lights.

Battery voltage range is up to 72 volts. But you can not connect 4 of those panels in serice since the peak solar voltage is 150v and 4 panels will damage the unit. So better go 2 sets of 2 panels in series/parallel.

I'm sorry, but I'm not familiar with the system you are asking about, but if the system outputs 6V to 12V DC, it should work.

It will work....however, you would only need the charger if you were going to use a generator to charge the batteries when the solar panels were disconnected or not charging. The solar panel connects to the batteries through the charge controller....then the battles connect to the inverter. Hope this helps!

As long as you wire your 3 12volt batteries in parallel, this panel will work. There are built in bypass diodes. But to avoid back flow charging from the battery, you will need either a charge controller and 5Amp is sufficient for the rated current of charge controller.

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!!

Actually neither. It delivers maximum power at 31.64V. This panel is made for working with an appropriate grid tie inverter, but it probably would work well for charging a 24V battery bank as well.
1825401
No!!! The voltage of the charger must be matched to the voltage of the battery system being charged. A 48 volt charger would see your 36 volt battery system as a very under-charged battery (not being 48 volts) and the net effect would be to damage your batteries attempting to bring them up to 48 volts.

The panel is rated for a nominal rating of 24V. It can deliver to a 12V or 24V battery bank based on the charge controller that is used. If you are using a 12V battery bank you will want to use a MPPT controller.
796339
only if you use a 12v charge controller and have you batteries wired in series. the output of the panel under load is a bit over 24v.

You would be looking at around 37V to charge a 24V battery bank at minimum. You can get 3 of these 37V panels and wire these in series and pump 111V under load into the battery bank with this controller. As long as the Voc voltage doesnt exceed 150V. The Voc voltage for these 37V panels is around 45V. You will get the 37V once its connected to the controller and in use but the panels will 45V just sitting there and measured with a voltmeter.

You can try it, and it should work, the unit has a input side for 48 volts and an out put side delivering a reduced 12 volts, I would not think the unit cares or could determine that the 48 volts was from a charger or 8 or 12 volt batteries in series. I am running all me 12 volt items,lights, horn,radio.
