This project was undertaken for a Solar Lighting System in a 380 apartment complex. The batteries are distill water type 2v 500Ah. The DC system is 48v and uses 24 of these batteries. The backup had fallen from 4 hours to 2 hours over 1 year of usage. Problem of too much acidic odour & sulphate accumulation on battery terminals also persisted.
After connecting the battery pulsers & over 2 weeks the acidic odour has reduced significantly. The terminals have remained corrosion & sulphation free. The backup time increased from 2 hours to 3 hours. The installation is under observation for further changes.
