other inverters.
or
Bridge the "A" and "B" screw terminals on the
middle inverter using a jumper wire.
Do not bridge the "A" and "B" screw terminals in
the two other inverters.
9. Measure the electrical resistance between the
positive and negative poles of the terminal block in
the middle inverter.
☑ If the resistance is approximately 27.8 k Ω
(±370 Ω ), the SMA Power Balancer has been
connected correctly. If not, check the cabling.
10. Close all inverters as described in Section 7.3 "Closing the Inverter" (page 51).
Connection with a Sunny Mini Central 9000TL, 10000TL or 11000TL
In order to be able to connect the SMA Power Balancer to a Sunny Mini Central 9000TL,
10000TL or 11000TL, the Sunny Mini Central 4600A, 5000A, 6000A must be equipped
with a special plug. Three inverters are then connected together using a special connection
cable.
You can order the plug and the connection cable from SMA Solar Technology AG or your
specialist dealer. Section 12 "Accessories" (page 79) contains a list of the order numbers.
