Been waiting since Sunday to run some checks on turnkey solar power system I set up.
Since Sunday, every day's been cloudy.
Today, no exception so far, even though a partly cloudy afternoon was forecast.
Still, I am running a six-watt LED light off a 300-watt inverter on the system today, with very, very minimal drop on the battery. This is under heavy overcast skies and using just one 100 watt solar panel.
Cloudy skies are forecast again tomorrow.
Guess I'll have to wait until Friday, or the weekend, before I get an idea how much I can run without drawing down my batteries on direct sunlight day.
