The cable length between two inverters may not exceed 300 m!
8. In the middle inverter only (with two wires for
each terminal), insert one of the jumpers provided
into the lowest of the three slots as shown on the
right.
Do not plug the jumpers into the lowest slot of the
two other inverters!
or
Bridge the "A" and "B" screw terminals on the
middle inverter with a wire bridge.
Do not bridge the "A" and "B" screw terminals in
the two other inverters!
9. Measure the resistance between the terminal
block's positive and negative poles in the middle
inverter.
☑ If the resistance is approximately 27.8 kOhms
(+/370 Ohms), the SMA Power Balancer has
been connected correctly. Otherwise, check the
cabling.
10. Close all inverters as described in section 7.3 ”Closing the Inverter” (page 55).
Connection with one Sunny Mini Central 9000TL, 10000TL or 11000TL
In order to be able to connect the SMA Power Balancer with a Sunny Mini Central 9000TL,
10000TL or 11000TL, the Sunny Mini Central 6000TL, 7000TL oder 8000TL must be
equipped with a special plug. Three inverters are then connected together with a special
connection cable.
You can order the connection plug and the connection cable from SMA Solar Technology
AG or your dealer. Section 12 ”Accessories” (page 84) contains a list of the order
numbers.
