gui: improve ESS wording

[mpvader]

Tasks

ESS settings menu:

• [ ] rename Zero feed-in (Fronius PV inverters only) to Fronius Zero feed-in
• [ ] rename Zero feed-in active to Fronius Zero feed-in active

Fronius PV Inverter menu in the device list:

• [ ] rename Power limit to Zero feed-in power limit
• [ ] remove Maximum power entirely

Discussion / undecided:

Wording as it is now:

Minimum Discharge SOC (unless grid fails), shorter and still understandable would be Reserve capacity.

Feed-in excess solar charger power, quite long. But I don't know a better one yet.

Better ideas welcome.

@edevries-victron: please make above mentioned changes. And what is the Maximum power for in the Fronius PV Inverter menu?

(in case someone wonders: that %key not found issue% on the vrm portal has been fixed)

[edevries-victron]

@mpvader 'Maximum power' is the maximum (AC) power capability of the inverter itself. This is the maximum AC power the inverter can deliver.

[edevries-victron]

After consult with @mpvader: remove 'Maximum power' from PV inverter menu.

@mpvader

• 'Reserve battery capacity' seems better to me than 'Reserve capacity', because it gives a hint we're talking about the battery SoC. Otherwise the user may have no clue what it is about.
• I bit nitpicking here: should Zero in Fronius Zero feed-in be capitalized?
