The sun has been hidden (mostly) for quite a while. The battery I used is almost empty.
This is a good test of the system. The energy generated by the panels is simply too low for the load.
All the radio equipment is now running on mains power until the battery is (at least) 50% charged. That may take a while, as the days are short at 55 deg. North. More panels are definitely needed.
I will also have to make a test of RF noise generated from MPPT controllers. Those are definitely more noisy than the lower cost and lower efficiency PWM controllers. If I can reduce the noise to a sufficiently low level I will probably switch to MPPT. The expected increase of power is between 20 and 30%.
For now the battery receives a very low charge, simply because it has been cloudy for more than a week.
The existing panels used for charging are 2x 130W.
I would expect to go solar again in mis February.
Yes, the station needs to be more energy efficient, and the battery/panel system needs to be improved. Still mush to do. Much of the indoor work should be done in the winter time: Monitor receiving system with lower energy consumption, and the bigger battery.
