• Output power: Output power of the inverter
• Act. daily yield: daily yield from 0:00 until now.
• PV voltage: the voltage supplied by the solar modules
• PV current: the current supplied by the solar modules
• Grid voltage
1)
• Grid current: the current fed into the mains grid
• Grid frequency
• Internal temp.: the internal temperature of the in-
verter
• Derating: cause for derating
• Max. daily power: the maximum power supplied in the
