Typical charge cycle: MPPT until 14.4V, then switch to CV and hold
14.4V. After 2 hours switch to float charging at 13.8V.

2. the UART
The CPU load calculation has been removed/commented out, as it is no
longer used.

New approach to MPP tracking

Test multiple points for PWM, switch to the one which gives the most
power, repeat. If two consecutive tests give the same point, hold that
for some time or until power changes too much.
