I have a 24v system at maximum 400 solarwatts input. 3 rolls = 408 watts. will these be OK to use?

If I understand your question correctly. your requirement is for a 400 watts solar input and if 408 watts of solar input is ok, I am assuming your question is for an off grid system (charging batteries). Question is if your your charge controller can accommodate additional 8 watts of input or ignore this additional watts without damaging any of the equipment. Please check the documentation of your equipment (charge controller) if it will work properly with the additional power provided by the solar panels. Normally additional power provided by the solar panels is ignored, one should make sure that electrical specs are matched with the solar input with the charger such as input voltage 24v panel and 24v charge controller input. Output from the charge controller should be matched with the battery voltage such as 24v solar panel, 24v charger and 24v battery, if different use an MPPT charge controller which can accept higher voltage from the solar panel and charge a lower voltage battery such as 24v panel, MPPT charge controller and 12v battery. Hope I have answered the question.

it really will depend on the specs from the panels you choose but i would say if they are similar to something like the renogy 100 watt panels you could run at least four for sure and possibly more depending on the actual output from each panel. if i was running more than 400 watts of panels i would probably start looking at some of the mppt charge controllers so you can get the most out of your system.

you have to look controler . to see if it can handle 46volts . as most 24 v system . handle 32v . are you sure you not have series them ? is this unloaded voltage ? even that seems high as mosr are 42 v . most charge controler have a 28 .2 voltage full charge cut off . it in equzation mode 32v . this why most panels are over rated . in watts , good rule is take away 1/4 . so a 1000 watts realy put out 750 . a mppt control helps by 30% .

They are rated to handle up to 250VAC at 10A, so your 24VAC should not be an issue.

This is why I hooked my 520 watts of panels in series so you halve the amperage. I can add another 2 panels in the future and still keep it under 30 amps. Remember too that the charge controller can charge a normal 12v battery bank, that's what mine is. I recommend making a 24v panel setup.

I think it really depends on several factors. Are you going with 12V system or 24V system. I am using the solar panel for 12v system on my RV in remote areas and have an inverter to run few 110v devices. Typically I get 10 amps during the day in the summer and less in the winter months. You can get more with better controller. With 4 storage batteries it is adequate. If I was in a cabin I would try to maximize on power capable on this panel and build a 24v system and use an inverter to supply 110v for in the cabin. With 24v system, because this panel output is 37v you get more power. It also depends on what appliances you have in mind. In general you really can't run any appliances that use lot of power like large fans for long. But you learn to convert everything to low energy use devices. I have converted all the lights to LEDs. Prior to conversion regular lights would drain the batteries in hours. But with LEDs it takes weeks. I think with enough storage batteries one panel is adequate, but if you spend lot of time in the cabin in the winter months, I would install 2 or more. In general this large 37v panel is better buy than several 18v panels. Hope that helps.

Not sure of the question?4 24v series panels will put out 96vdc.Be careful and remember that 24v is nominal output, the real max output per spec can be 33vper panel.So 4 24v panels in series can generate a max voltage of 132vdc.I personally add in at least a 20% margin over spec on all calculations.Yes, I believe you can run higher voltage/lower current at the array and the Mppt can auto convert to 12v.You might check the specs for max current/voltage/power and also the conversion efficiency.

It will be ok as long as they are not over 35 watts.Please let me know if there is anything else I can do for you or if you have any questions.Sincerely,Briana

3 kwh. =3000 watts , unit rated for 4000 watts at 48 volts ( battery bank), there is a rating for 60 volts as well, i would not use it at 36 volts because that is the max. rating for that voltage (3kwh). those controller have a habit of getting as much as 10% more wattage out of solar panels, at times. there is a max. for voltage input , i believe it is above 140 volts so keep your input below that.

That would depend on the voltage of the system these lights are put in. In a 12 volt system, 27 watts would be just over 2 amps.

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.

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.

Besides this kit you would need a tray cable that connects your controller to the battery bank. Since you would are doing 400 watts on a 40 amp MPPT we would recommend adding a 40 amp fuse in between the controller and battery.

I connect to 24v batteries rather than solar panels to get max 300w out. The batteries are solar charged.

The whole point of this type of controller is to take your solar power of any voltage up to 48 volts (in this case) and output the proper voltage 12 or 24 volts to your batteries. Your panels do not need to be 12 volts, they simply need to fit in the specs of the controller which is a 48volt maximum input voltage. It will then regulate your output voltage to 12 or 24 volts, whichever you choose.

All Depend on what you are using the solar system for. I have two of these battery charging a small fish pond with total of four pumps, that not of enough battery. I have 200 watt system, use as many battery of same size as you can afford. Good Luck

i use a 400 watt converter which is the max i believe without adding panels...
