• 7:05 AM 18.7V cloudy prior to turning on inverter.
• Shutoff - works at 7 PM on sunny day, otherwise 9-6
• Sunset - 8:30, rise 6:00 on May 15.
• Now it's 8:40 and 5:50 set/rise
• Today,turned on inverter at 8am with light full cloud cover. Drops to 15.9, then rebounds to 18.7. There is a minute or two delay before charging is activated.
• 25.5V night time at 9:30 pm, inverter off. Seeing full charge drop at 9 pm may be a good metric for decay of battery power? Probably better is voltage drop from a heavy load.
