Newb here.
Currently following the steps to flash my S3-WIFI-ST stick per the readme.

Can you provide some further guidance on the packages section?

#Uncomment exactly one line depending on your device type
#inv: !include common/solis-modbus-inv.yaml
esinv: !include common/solis-modbus-esinv.yaml
#epm: !include common/solis-modbus-epm.yaml

#Uncomment for optional INV inverter addon: Single Phase ACR10R energy meter
#inv-acr10r-1ph: !include common/solis-modbus-inv-addon-acr10r-1ph.yaml

#Uncomment for optional ESINV inverter addon: timers for battery charge and discharge periods
#esinv-timer: !include common/solis-modbus-esinv-addon-timer.yaml

I have a Solis S5-EH1P5K-L which is a hybrid inverter, so I've uncommented esinv.

I do also have an ACR10R connected to the RS485 port of the inverter, should I uncomment inv-acr10r-1ph? Or is that only for INV and not ESINV? What does uncommenting that give me that I wouldn't get with it commented?

I do also use the timer functionality on the inverter to control charger/discharge of my batteries. Do I uncomment esinv-timer too? Or is that related to some other kind of harware addon that would need to be connected? What does uncommenting give me extra, control of the timers from within HA?

Thanks in advance and sorry for being such a newb!
