String Inverter selects the brand of Selectronic Certified grid inverter(s) that are
connected to the SP PRO in the Managed AC coupled system. Only one brand
of grid inverter may be connected to the SP PRO although any mix of compatible
models within that brand may be used.
The SP PRO firmware comes in four versions based on the Selectronic Certified
gird inverters installed. Powador, ABB Solar, Fronius and Select Sun. If the firmware
within the SP PRO does not support the configured
String Inverter
then SP LINK
will go to the Firmware Update screen ready to update to the correct version of
firmware. See Firmware Update on page 27.
In a Powerchain configuration, different brands of string inverters may be configured
for each phase manager. However each phase manager may only have one brand
of inverter.
At least one String Inverter must be configured on the System Manager (L1 phase
manager) before any String inverters are configured on the L2 and L3 phase
managers.
When a three phase Powerchain system is configured, three phase Selectronic
Certified string inverters may be used, being the Fronius Symo and the SelectSun.
Up to five three phase string inverters may be configured on each phase manager
giving a maximum of fifteen (15) string inverters per system.
Number of Devices sets the number of compatible inverters that are connected to
the SP PRO in a Managed AC Coupled system. The maximum number of units per
phase manager is five.
Please ensure that the combined AC output of all connected
Selectronic Certified grid inverters does NOT exceeding twice the
AC Power output rating of all of the SP PROs in the Powerchain
system (some exceptions apply based on battery size - Run the Site
configuration wizard to verify your design).
Kaco string inverters may not be used in a Powerchain system that has
more than one SP PRO per phase (a system with managers only. No
workers)
Fallback Power . Only used with KACO Powador 00 or 02 series inverters built in 2014 or later. See “IN0018_
xx SP PRO KACO Managed AC Coupling Installation Notes”
