4 x 270 W Axitec panels - Easysolar 48/3000-MPPT 150/70 - 4 of 200 A (12V) AGM bat in series = 48V - Multi 48/3000 in a easysolar . - BMV 700- Color control . Caribbean area.
Axitec panels are 270 W - 31,12 V 8,71 A
OCV = 38,21 V scA = 9,25 A
I had a easysolar 1600/24 with 100/50 MPPT. My panels were in 2 series of 2 for voltage.
I now have a Easysolar 48/3000 with MPPT 150/70. I passed my batteries in 48 V.
For now, I still have 2 pairs of cables arriving from my solar panels . Accordingly there is a little difference between panels voltage and battery voltage .
I like to have far more panels V than Battery. For this one, I am hesitating.
If I put all my 4 panels in 1 serie, I will have :
- Nprmal operation : 4 x 31,12 V = 124,48 V @ 8,71 A . perfectly within MPPT 150/70 limits
- My Open Circuit voltage (max) would be 4 x 38,21 V = 152,84 V ! Slightly above the 150 V limit for the CC. However, I am in the Caribbean with hot temperatures year round ; lowest ever might be 17° C .
Appreciate comments to see if I could take the risk and have only 1 serie of 4 panels .
