Bugfix: Add messages needed for Solax Ultra

[dalathegreat]

What

This PR fixes missing SOC% in app when using Solax Ultra inverter

Why

Better user experience

How

We send 5x CAN messages on boot towards the inverter. From testing, it appears that only sending these messages once seem to do the trick

Fixes #650

The first battery is now working fine, but the SOC (State of Charge) of the second battery is not showing up, and as a result, it does not work with the Solax Data Hub.

@DeadmaroZ-TLOTL I suggest you make a new issue detailing the problems with the second battery. Please write as much info as possible

Its a full can frame from solax ultra with two batteries, 1st tesla, 2nd solax triple battery

[dalathegreat]

@DeadmaroZ-TLOTL Unfortunately I think your setup is a bit too specific for anyone on the Dev team to be able to fix it. Since we fixed the Tesla by sending more CAN messages, I dont think we can fix the OEM Solax battery... Maybe reach out to Solax support (but don't mention the Tesla battery, or your warranty will be void and inverter risks being blocked)

[DeadmaroZ-TLOTL]

This is not my setup but a CAN log from a setup where there is 1. a Tesla battery and 2. a Solax Triple battery. This setup was only for logging CAN messages. If the Tesla battery is connected to the 2nd battery output, the percentage is not displayed on the main screen. The Data Hub also doesn’t work, even if the Tesla battery is connected to the 1st output. with OEM battery all OK
