SMA Solar Technology America LLC 4 Product Description
Depending on the requirements of the grid operator, you can activate and configure the functions
(e.g. active power limitation) via operating parameters.
SMA OptiTrac Global Peak
SMA OptiTrac Global Peak is an advancement of SMA OptiTrac and allows the operating point of
the inverter to follow the optimal operating point of the PV array (MPP) precisely at all times. In
addition, with the aid of SMA OptiTrac Global Peak, the inverter detects several maximum power
points in the available operating range, such as may occur particularly with partially shaded
strings. You can activate SMA OptiTrac Global Peak via the operating parameters (see Section 8.5
"Setting SMA OptiTrac Global Peak", page 37).
Arc-Fault Circuit Interrupter (AFCI)
®
In accordance with the National Electrical Code
, Article 690.11, the inverter has a system for arc
fault detection and interruption.
An electric arc with a power of 300 W or greater must be interrupted by the AFCI in the time
specified by UL 1699B. A detected electric arc causes the inverter to interrupt feed-in operation: In
order to restart feed-in operation, the feed-in operation must be activated manually. If the
installation conditions allow it, you can deactivate the arc-fault circuit interrupter.
Q on Demand 24/7
The inverter can supply reactive power by means of Q on Demand 24/7 covering the entire unit
circle around the clock (for details on the configuration refer to the Technical Information
"Integrated Plant Control and Q on Demand 24/7" at www.SMA-Solar.com).
Integrated Plant Control
The inverter can display the Q(V) characteristic curve specified by the grid operator by means of
Integrated Plant Control without measuring on the grid-connection point. The inverter can
automatically compensate equipment installed between the inverter and the grid-connection point
after having activated the function (for information on the system configuration refer to the Technical
Information "Integrated Plant Control and Q on Demand 24/7" at www.SMA-Solar.com).
