4 Product Description

4.1 BatFuse

The BatFuse is a battery fuse box that acts as a DC fuse by protecting the DC cables of the
Sunny Island. The BatFuse enables disconnection on the DC side.

The BatFuse serves as DC busbar for the installation of the Sunny Island Charger.
The BatFuse is available with various fuse links for the different power classes of the Sunny Island

inverters.

Fuse Links of the BatFuse-B.01 for a Maximum of One Sunny Island

Device type Sunny Island Recommended fuse link

Sunny Island 3.0M 80 A
Sunny Island 4.4M 100 A
Sunny Island 6.0H 160 A
Sunny Island 8.0H 200 A
Sunny Island 5048 250 A

Fuse Links of the BatFuse-B.03 for a Maximum of Three Sunny Island Inverters

Device type Sunny Island Recommended fuse link

Sunny Island 3.0M 80 A
Sunny Island 4.4M 100 A
Sunny Island 6.0H 160 A
Sunny Island 8.0H 200 A
Sunny Island 5048 250 A

The BatFuse features a battery voltage tap to which the following loads can be connected:

• Sunny Island load-shedding contactor

• DC-to-DC converter for supplying a Sunny WebBox, a Sunny Boy Control or a battery room fan

The battery voltage tap guarantees an interruption-free supply of the connected loads when the AC
grid is switched off or under fault conditions.
