added slightly expanded AC180 support

[alexnathanson]

I identified the following registers:

device type: 1101
serial_number: 1107
battery type: 6101
battery serial number: 6107
bcu version: 6175
battery percent: 102
output mode: 123 (returns 32 when both loads off, 40 when AC is on, 48 when DC is on, 56 when both on. This is accurate, but may not be exhaustive if there are other additional modes)
dc output power: 140
ac output power: 142
dc input power: 144 (this is an educated guess and not tested, because I didn't have a PV module handy)
ac input power: 146
power generation might be 1202 or 154, but I can figure it out once I connect a module.

@alexnathanson I incorporated your changes into my fork: https://github.com/ftrueck/bluetti_mqtt/
I hope that @ZachGoldberg will give it a try to build a woking HA addon with it.
As long as @warhammerkid is MIA we could at least keep the library up and working.

Thanks for hunting these registers down.
there is no "output mode" in mqtt_client.py
So for me, this value is not sent out.

Hope you dont mind me putting it in this way. I have no inclination to create a fork, maybe a spoon :)
I have the controls for AC and DC working in Home Assistant now. Nothing clever here I jusy noticed the AC60 had very similar controls.
It needs a bit of tidying up.
I will experiment a but more, but I am away till next week now, but thought I would share it for now.

Just want to add I tested this code on AC180P and can confirm it works great:

{'battery_type': 'AC180P', 'battery_serial_number': 23440040765XX, 'bcu_version': Decimal('1039.01')} {} {} {} {'total_battery_percent': 72, 'output_mode': 40, 'dc_output_power': 0, 'ac_output_power': 56, 'dc_input_power': 0, 'ac_input_power': 0} {} {} {'device_type': 'AC180P', 'serial_number': 23440040765XX} {'power_generation': Decimal('0')}

Thanks!

Glad it help. I know I was so relieved when it all started to work as intended. I've been able to automate switch on and switch off, and it ticks along nicely. I do wonder if I could get away from having to have the bluetti-mqtt running on the PC, maybe in HA, or trying to get the esp versions working, and I did try them, but without success. So just sticking with what works for now.
