It sounds complicated and will require some thought. The timeslot is reported as a string so you need to convert it to a date format. It also requires another 12 sensors, one for each time slot and timeslot SOC. My initial thoughts are it falls outside of the scope of this card.
BTW I just released v1.5.0 of the card that includes the optional addition of remaining solar forecast for the day. I've also included the actual time that the battery will be fully charged or shutdown SOC reached based on the suggestion of @SteveRCT 

 

Have a look at the latest release. It includes the time to full charge.

Sorry to disappoint,  but i took a very ghetto approach to the 2nd inverter because i have 2 in parallel i just doubled all the sensor readings, completely wrong way to do it but i don't know how to code... I'm only about 5w off from the true readings though

Thanks Gary! Not going to lie reading your work and how it's integrated is teaching me so much in other areas of home assistant, as a tutorial,  and working with troubleshooting other  things I'm trying to get running in home assistant.
