8. Only in the middle inverter (the one with
2 insulated conductors for each terminal), insert
one of the provided jumpers into the lowest of the
three slots as depicted on the right.
Do not plug the jumpers in the bottom 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 k Ω
(±370 Ω ), 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 59).
Connection with one 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 7000HV must be equipped with a special
plug (Order No. PBL-SMC-10-NR). Three inverters are then connected together with a
special connection cable.
You can order the 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.
