5.2. EFF – SETTINGS FOR TESTING PV SYSTEMS (ONLY SOLAR I-V)
Further in this manual, the acronym MPPT (Multiple Power Point Tracker) shall indicate
the characteristic of the DC/AC converter (inverter), capable of maximizing the DC power
which can be taken from the photovoltaic field. See § 11.2 for further details.
5.2.1. Settings for PV systems with single-MPPT inverter - single-phase AC output
Check beforehand the settings made in MENU
SETRemote Unit and check that you
have selected “SOLAR” as setting for parameter “R. unit”.
