Hello Folks,
I come to you with great hope. I have invested huge amout in solar Equipment and yet unable to get even half of rated output.
My Solar setup consists of -
Solar Panels- 250 wp, ( I brought 4 panels)
VOC 37.6v
Short circuit current- 8.5A
Rated voltage 31.4V
Rated amperage- 7.94V
Batteries- 12v Lead acid 150 AH in series for 24 system
24V 1400VA inverter
DC LED lights and other load via inverter.
Solar Charge controller-
24v, 20A, PWM type. The best controller i could find in india.
---------------------------------------------------
Now,
DO as I might, I am unable to get the rated Amps out of the system.
Currently I have connected TWO pannels in parallel, That should make them ABOUT 30V, 16A... Thats good enough for 24v System to charge at worst case 15A charging, No?
I get only 6 Amps!
Now I connected 4 panels in parallel, That should be 30v, 32A. lets Take it down to 20A worst case, But NO!
What I got max ever was 10A!
As a result, what happens is 24V Battery bank runs down to 22V and The inverter Trips. I don't know why the charge controller can't provide full 16A+ and bring battery bank upto atleast 25v with Sun brightly shining?
How is this happening? I have already returned the Panels thrice and Changed controllers 4 times (with different models). Are companies lying? Why can't i never seem to get rated outputs?
