Dear All,
This is a very weird problem i am facing for the last couple of days.
My company installed a solar powered street light couple of days ago. The details of it are:
Solar Panel - 2*60W@12V = 120W
Charge Controller - 10A@24V (PWM)
Battery - Maintenance free sealed Lead Acid Deep Cycle Batteries 140Ah@12V*2
Now the problem is the battery is not charging. The Controller has sensors installed in it which shows the level of battery charge. Initially it operated very smoothly for 2 weeks operating for 8/9 hrs per night. But now it turned off after 3/4 hrs and today while i checked the system i found the controller is showing very low battery charge. There is abundant sunshine and the battery voltage is 11.5V respectively with total system voltage 23V.
So i badly need to know whats wrong here. Also i need a urgent solution. I have already changed the batteries once but the new ones are also causing the same problem.
Please help me quickly.
Thank you and with best regards,
