Hi all, New to forum and solar
Thanks for reading my post, i’m having problem to get my batteries fully charge – 69 to 73% is all and this is a 3 week old system, maybe i’m missing something or my setup is not correct
I've even did not draw / use any power for 2 day's from the system to see if that would help but only got it to 75% charge
The electrician helping with installation confirmed all connections is correct, but could not assist further
During the day there is nothing drawing power, put inverter off during daytime, sytem is curentlly only used for 7x house lights during night – all bulbs change to LED 11/18 W - the idea is to slowly add
My system:
6x 300W panels Series/Parallel connect 24V – spec’s Vmpp 18V, Impp 16.67A, Isc 17.83A, Voc 22V
6x 200AH 12V 25C Gel Batteries, Series /Parallel 24V
SAKO SC2450 PWM 50A / 24V Charge controller – DC out 15A - Auto settings Bat low – 21.1V, Low back – 23.9V, Bat high – 28.9V, Bat high back - 27.2V, Bat float – 27.0V, Bat Vast – 27.8V, max current 50Amp
SNK 3000W pure sine inverter
I suspect my charge controller maybe not be up to the job - i was under the impression it was a MPPT controller until i check the web site of the Manufacturer and found out it was a PWM controller
I live in Namibia, 5/6 hours direct sun on panels, any input will be appreciated
Thank you,
