ger1000B support up to 4900 RSDs.
Requirements for PV module connection
• Up to 15 RSDs can be installed in each PV string.
• The number of PV modules connected to RSDs in each PV string must not exceed the
maximum number of modules allowed in one string by the inverter.
• The maximum open-circuit voltage of each PV string must not exceed 1100V.

4.3.1 Installation Scenarios
Clip-on mounting
Bracket mounting
• Before installation, select the appropriate RSD variant and decide the installa-
tion and arrangement schemes based on the actual situation, to ensure that the
RSD can be connected to PV modules and adjacent RSDs normally.
• The mounting and wiring should be performed in compliance with local laws,
regulations, safety standards, and installation specifications. If the cable is too
long, do not let it hang down to the ground. You can secure it nearby to the
bracket or the edge of the module.
4.3.2 Preparation Before Mounting
Choose a mounting method based on actual needs
Decide the installation position of the RSD properly, to ensure that the RSD can
be connected to PV modules and adjacent RSDs normally.
Decide on an appropriate position to mount the RSD. Remove the QR code label from the
RSD, and attach the label to the template paper by referring to the instructions for "Physical
Layout Template".
User Manual 4 Mechanical Mounting

4.3.4 Mounted on Aluminum Guide Rail
Step 1 It is recommended to use M8×25 T-head bolt (not included in the scope of delivery). Slide the
T-head bolt into the groove in the aluminum guide rail.
Step 2 Hang the RSD to the T-head bolt by its hanger, then fit the nut onto the bolt using a socket
wrench, to secure the RSD to the aluminum guide rail. They are connected together in the
order of nut, hanger, and then T-head bolt.
• During installation, make sure the metal clips do not get in contact with the
bracket.
• Install the RSD with its back tightly against the bracket. Installing it from the
opposite direction may damage the RSD and such damage will not be covered
