Ok, so thats what the answer is then. Even if the Voc was 36v I would rate amperage by watts/battery voltage,, and not whaat the panels are rated to.. 200 watt panel @ 24Voc going into a 12v battery would be 200/12=16amps... If it was a 200watt panel @ 36Voc going into a 12 volt battery it...
I am installing full time roof mounted solar on my RV and am thinking I should have a solar disconnect switch besides the ground disconnect switch. The ground disconnect will take out my battery system and that leaves the solar controller hooked up to solar only and from my understanding and...
Am wiring in solar on 12v parallel battery sstem, panels are 1 @ 200w + 1 @ 210w and will be wired series= 2 @ 400w/24v= 16amps. But the question is to install disconnect switch on hot side or ground side prior to input to cntroller. I installed a ground disconnect on battery side to battery...
yes but its 40 amp and not sure on wiring or exact length. What I am trying to find out is if I can mix panels up as I stated.. I could not find anything saying it was aa no-go or bad or whatever. I am trying to get more input if possible. I have a much cheaper controller Rengoy that worked...
Thats what I was thinking that they were 24V but the seller ads them as 12v..?? I was debating series or parallel but heard that if one panel gets shaded (especially the one closest to input manifold) I will lose all or most charging capacity? Also, if I go in parallel it will be 24v and...
This was kind of covered while learning other topics but want to just get this down.. The numbers are ballpark, used for reference..
SERIES INSTALL:......2 panels 200w suppying 12v system. It would be 24v @ 16 amps.. If either the front or rear panel gets shaded it switches to 12v @16...
From my understanding the lithium iron are the ones most susceptible to fire? Are there other lightweight, long lasting, quick recharge, etc., qualities of the lithium iron that are not known to catch on fire? Isn't lithium just part of the battery make-up of its chemical/mineral charging...
I have 2 -12V glass 57x28 galss panels now, 1 @200w and 1 @210w and was wondering about hooking them in series for 24v and getting 1 more 24v 200w panel and hooking them into a 4 port manifold that has all inputs wired in parellel on the output end.
In the end I would have 2 @12v series...
I think I would be better offgoing 12v parallel in case I get one panel shaded.. Then am not having to purchase another right away and can test system out.. As they are rated at 24Voc but called 12v,, how would you rate amperage, 12v @ 16amps or 24v @ 8amps????
I am curious, if one or other (ground or hot ) is open there is no completed circuit so no flow of electrons can go?? If can only open one side would the ground be best?
And got it on the typing, it happens to me all the time.. Thank you for the quick follow up relpy also Supervstech
Was wondering on use of these; Bypass for series and blocking for parallel,,, ball park right?? Blocking are like most MPPT's it seems, voltage can vary (5-150) for example only,, but current is more critical? Lets say have 2 panels rated same 200w for 12V system (example only) and each one...
A PS. batteries are 2 @ 12V in parallel so from SCC to batteries would be either 12 x 9.9i = 118.8 W...………. or 12V x 19.8i = 237W ??
Just re-read posts and VOC,,,,200 W = 24.3V...….. and VOC,,, 210W = 24.9V
Yes, I got two from Amazon @ 15amps, was highest amperage I could find that wouldn't take 2 months to get here. I think this place was one that would take a month to get here. I ordered 2 @ 15 amps, which is hairs wisker from my max current will be parallel. Will try these wen get it...
""Vmp @ Imp"" you lost me on that one. The open voltage is 24V, so is amperage rated at 24v or 12v? From my understanding the Voc is to provide enough volts t open the chargr for a 12v battery, if it was supplying 24v battery system the Voc would be about 38Voc (just guessing on that...
Got it, thank you so much for simplifying it.. That's what I originally thought, 2 panels at 200W = 400W total divided by either 12 or 24 volts to get basic need for design/layout options. 32 amps total parallel and 16 amps total series with noted total voltage differences used.
thank you and...
So my panels at 200 watts and being 24Voc each will be 8.3 amps each? Even though were sold as 12v, each panel is to be formulated at being 24volt prior to being installed?
So what woud you rate your wire at, 8 amps for the panel 24Voc,, or 16 amps for the battery ratings? Or would you have two different wire selections, one for panels to controller then another for controller to batteries??
