What is the VOC of the panels?Got 4x 400 watt solar panels which going to run in series so amps stop same volts go up 33 amps 48v you get more draw on volts on each panel would a mppt 150/50 do victron thanks
x 4 = 180.56 VOC45.14 volts
3s at 45.14V VOC is still very close. What’s the historical coldest these will ever see, -20f?It's 3 string sorry
VOS isn’t VMP, so the unit won’t be working that high so that isn’t the issue. It needs to isolate current or initiate current.Agree with all above. 3x45.14=135.42, still too close to the rated volt. It's not a good choice. To keep the controller working at high volt will consume its life quicker. 2s2p is indeed a better idea.
He corrected and implied he only had 3 panels, not 4With 4 panels available. 2s2p is the best choice.
Actually, they said "3 string". Not even sure what that means.He corrected and implied he only had 3 panels, not 4
Not sure about 2s2p not clue want that meansAgree with all above. 3x45.14=135.42, still too close to the rated volt. It's not a good choice. To keep the controller working at high volt will consume its life quicker. 2s2p is indeed a better idea.
The first 2 series panels would be 33amps the parallel 2 would be 66amps which is 96amps is that right2s2p
Two panels in a series string. (2s)
Two strings in parallel. (2p)
NoThe first 2 series panels would be 33amps the parallel 2 would be 66amps which is 96amps is that right
Would it be wired like thisNo
Two panels in series. (A series string)
Voltage is added together and amperage stays the same.
Repeat this for the other two panels.
Then put the two series strings in parallel.
In parallel, the voltage stays the same. And the amperage is added together.
The end result would be (according to the panel label), 2 x voltage and 2 x amperage.
YesWould it be wired like this
