mains battery charger

Branch Description

This is the zero branch where the initial development of the mains battery charger happens

Future Work

This program may read command line data for setting the loglevel before the configuration file is read.

Description

This program automatically turns the mains battery charger on in case the solar battery becomes discharged beyond a certain limit.

This is essentially a bang-bang controller where the AC charger is turned on if the battery is lower than the low-threshold and turned off if the battery is higher than the high threshold.

Thresholds and Time of Use (ToU)

Time	Low Threshold (on)	High Threshold (off)

16:00 to 21:00	5%	10%
