MrMessy I presume this is likely to do with firmware version etc.
How on earth are we supposed to know what to use? It's bizarre that Giv don't have a consistent implementation and inverter and FW differences effectively bleed out into the public API, which then makes it hard for any and all consuming services/apps that are using the Giv API.
@KristianS Could you see what Giv suggest here? They really should make sure there's a much more consistent implementation, ie. for your flavour of AIO and fw version, setting the main AC Charge Upper % Limit should simply result in setting the underlying AC Charge 1 Upper % Limit register (if that's the only one that seems to have an effect). The mapping should happen on their side, rather than push this upstream.
