Use MQTT to enable/disable SmartSolar MPPT

How do I change the "charger enabled" setting via MQTT? I can read and write values, just need to know which topics, if any, need to be changed. My end goal is to enable/disable the MPPT's based on several variables in my RV automation software.

for example:

N/d41243d304cb/solarcharger/277/Mode

N/d41243d304cb/solarcharger/277/State

When I write this value with MQTT explorer I see the value briefly change but then it returns to the original value. So it doesn't seem to be remotely writeable, any idea what I may be doing wrong?

You must send the change to

W/d41243d304cb/solarcharger/277/Mode
