Hi all. I have a Voltronics Axpert MAX, installed here in Chile (220V grid power). I cannot force the unit to output at 220V, either from the panel itself, Watchpower or Solar-Assistant. It accepts the change from 230 (default) to 220, but it never actually changes, even if the setting is accepted and displays 220V for a time. After a while the setting goes back to the default 230V, and it NEVER does the actual voltage switch.

Any ideas? @Coulomb?

AFK, but I vaguely recall that the output voltage can only be changed when inverter switch is off, like the output mode setting. I thought that if the switch is on, the command should just be NAK'd. Perhaps Watchpower doesn't check the response.
