Direct Control Guide

Hi

Does anyone have a helpful list of the local control registers and what they actually mean? Since the paywall went up I’ve lost access to the basic settings for things like max charge and discharge rate, reserve percentage and max charge, basically everything that was on the Inverter settings page for my AIO.
I did request the ‘premium’ team help with this but they are focused on helping paying customers and my £LOL from the install of the system doesn’t seem important anymore despite only want to control this from inside my home.

Thanks

The phone app in local direct control mode lists all the registers and what they are for in your install.

It gives a very vague description, so not really that helpful particularly when a few seem to say very similar things and other have settings which I don’t recall ever touching. Quite why the ‘Inverter Settings’ page couldn’t just be populated by the registered locally I don’t know but those are really the things I’m looking for.

There is a good list here in the GivTCP code on GitHub:
