'Advanced Grid
Features'
FCC / RSS Com- FCC
pliance This device corresponds to the limit values for a digital device of class B in accordance with
Part 15 of the FCC regulations. The limit values should provide adequate protection
against harmful interference in homes. This device creates and uses high frequency ener-
gy and can interfere with radio communications when not used in accordance with the in-
structions. However, there is no guarantee against interference occurring in a particular
installation.
If this device interferes with radio or television reception when turning the device on and
off, it is recommended that the user solve this with one or more of the following measures:
-
-
-
-
Industry Canada RSS
The device corresponds to the license-free Industry Canada RSS standards. Operation is
subject to the following conditions:
(1) The device may not cause harmful interference
(2) The device must accept any interference received, including interference that may
cause undesired operation.
Ground Fault De- The inverter is fitted with the following safety functions as required by UL 1741 and the Na-
tector / Interrupt- tional Electrical Code:
er, Insulation
Monitoring Ground fault detector / interrupter (GFDI)
In photovoltaic systems with negatively grounded solar modules, the negative cable from
the solar module is connected to the grounding system in the inverter. If a ground fault oc-
curs in the DC wiring, the inverter disconnects from the grid.
Insulation monitoring
In photovoltaic systems with ungrounded solar modules, the inverter checks the resis-
tance between the photovoltaic system's positive or negative pole and the ground poten-
tial. In the case of a short circuit between the DC+ or DC- cable and the ground (e.g., due
to poorly insulated DC cables or faulty solar modules) the inverter disconnects from the
grid.
Arc detection/in- The inverter is equipped with integrated arc detection/interruption, which detects and ex-
terruption tinguishes serial arcs.
For example, a serial arc can occur after the following errors or situations:
-
-
-
-
90
adjust or reposition the receiving antenna
increase the distance between the device and the receiver
connect the device to another circuit, which does not include the receiver
for further support, please contact the retailer or an experienced radio/TV technician.
Poorly-connected plug connections on the solar module
Poor or defective cable connections on the solar module side, which enable a connec-
tion against the earth potential
Defective solar modules due to problems in the junction box or production errors, such
as high resistance solder connections in individual solar cells
Cables incorrectly connected to an inverter's input terminals
