I installed a 10kva 48v solar inverter system using the following:
One hybrid inverter with 120A charge controller with 3300w panels connected to it
Another 120A charge controller with 4950w solar panels connected to it
My battery bank is made up of 12, 12v 220ah tubular batteries. 4 series to give 48v, and paralleled to feed a bus bar. My total battery bank 31,680kwh.
My problem here is my system won’t power a 1000w load even 6 hours at night.
Important details to note.
1. At commissioning, I noticed the battery charges to 59v (I usually leave my charge controllers at default settings) and I could hear the battery boiling , after that I had to set both charger controllers for floaded.
2. After 3 weeks of use, I noticed corrosion at the positive and negative terminal of 2 out of the 3 48v banks connected to the bus bar.
I would like to know I anyone has experienced this or if I’m doing anything wrong from the setup. I want opinions from other professionals
Are my batteries over charged from the system because my charging current on a normal day is approximately 30A
