SMA Regelsysteme GmbH

 

We urgently recommend a fused interrupter to disconnect the Sunny

Island. 

If there is no line protection (fuse) the installation of DC cables has

to be inherently ground-fault-proof and short-circuit-proof. The inter-

nal DC fuses of the Sunny Island are designed for interrupting cur-

rents of up to 20 kA (for 

R

L

 < 0,015 s ).  

The relevant regulations for installation have to be followed. 

Fused interrupter to

disconnect the Sunny Island

max. 25 mm

e.g.

Fig. 3.5: Connection of battery to the Sunny Island 

 

The nominal voltage of the battery to be connected is 60 V DC.  

Never remove the battery cable during operation. Always switch the

inverter off first.
