   # So, preventing the battery from getting full too early on a sunny day will increase our overall yield, because the
   # inverter won't have to derate the PV power to 5kW.
   #
-  # Possible approaches:
-  #
-  # 1. Set general charge/discharge limits or start power for charging from PV[1][2]
-  #    Unfortunately, it seems like these registers don't work on my inverter SH5.0RS, so this avenue is out.
-  # 2. When PV is >5.0kW and battery is not full (but not too low), set forced charging mode and set the charging power
-  #    to be `PV power - 5.0kW` to maintain 5kW of AC constantly. Unfortunately, forced charge/discharge power register
-  #    (13052) can't be set over Modbus (just ignored). So this option is out _at least until_ this is fixed or I have a
-  #    way to programmatically set this using the SunGather HTTP method (i.e. WiNet-S)
-  # 3. Set battery mode to Stop when all of:
-  #     * Cloud cover is low / weather is sunny
-  #     * PV power is higher than household demand (by some margin, like 1.5x to minimise grid buying)
-  #     * battery is not too low nor full
-  #     * the forecast has enough remaining in the day to fill battery AND cover remaining household usage (or a proxy
-  #       for this like, `forecast > 2*kWh_till_battery_full`)
