So I decided to watch the pattern of working and changes in indicators as well as the displayed information on my new MPPT Solar Charge Controller. I am using a single flexible 250W\/ 24V solar panel connected to this charge controller. Battery is 65 Ah Sealed Lead Acid Battery. I have connected a 1150W inverter to the battery, which is mostly on standby load without any significant load connected to it. Watched the pattern at various times of the day as well as after switching on a load connected to the inverter. Quite interesting observations are being demonstrated in the video.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I had installed it when the Sun was not that strong yesterday afternoon.
