I don't get the Solar requirement for a TPMS. The current the TPMS draws from the alternator is probably less than 1 amp at 12 VDC. You connect it to a switched power source and a good TPMS automatically turns on when you start the coach, and turns off when you shut the engine off. The battery stays charged so you can turn it on if you don't want to start the engine and as long as it's not a motion activated sensor, you get your tire readings in a few minutes.
