To have a safe code compliant photovoltaic system you need to install the appropriate disconnects, fuses and/or breakers
throughout your system. The National Electrical Code (NEC) states that a disconnect is required for every piece of equipment
(charge controllers, inverters, etc.) to isolate them from all sources of power (solar modules, batteries and generators). This might
sound complicated, but it is really pretty easy. On the following pages you will find several disconnect and overcurrent protection
options for your system. If you arent sure which disconnects you should use and where, just give your KSI dealer a call and he can
point you in the right direction.
SMA PV Combiner Boxes
The Sunny Boy Combiner Boxes, SBCB 6-90 & SCCB 28-420, make installing large projects easier. The large NEMA 3R
enclosures provide ample room for conductors and will help reduce installation time. Designed with installers in mind, you'll find
the new SBCB & SCCB Combiner Boxes, a welcome addition to the SMA product line.

OutBack offers a PV array combiner which can be used with a wide variety of PV system designs and module configurations. It
can be configured with DC breakers for low voltage systems (under 125 VDC) or touch safe type fuse holders for high voltage
systems (up to 600 VDC). PSPV is designed to provide NEC code compliant overcurrent protection and interconnection of
multiple PV panels or sub-arrays into one or more PV arrays for connection to charge controllers or inverter systems. The PSPV is
easily field configured to match your PV system design and ampacity requirements. 9.25 x 13.125 x 3.625
The PSPV Power system PV Combiner provides series over-current
protection of PV module circuits allowing NEC compliant installation.
Includes space for up to twelve 125 VDC rated breakers or eight 600 VDC
rated fuse holders. Includes two positive output bus bars with two #1/0
terminals for single or dual output circuits. The type 3R outdoor rainproof
enclosure can be mounted vertically, or inclined to 14 degrees (3 in 12
pitch). Enclosure only without breakers or fuse holders.

OutBack DC Ground Fault Protection System
The OutBack Power systems GFP/2 is required for PV arrays mounted on
dwelling roofs. A GFP/2 protects wiring and system components for one or
two PV arrays: Dual 60 amp PV circuits 125 VDC max Voc. Requires three
small breaker spaces. The GFP/2 has 1/4 stud terminals. The OBDC-GFP/2
system includes the GFP unit, a ground bus bar, neutral and ground
connection wiring and mounting hardware. The PSR includes mounting for
only one OBDC-GFP/2 along with two PV disconnects and one large battery
breaker. For use in OutBack PSR and PSDCs.

The Xantrex DC175 / DC250 disconnect offers the ultimate in terms of
overcurrent protection and a disconnect means for your inverter all in one
enclosure. It also interfaces very nicely with the Xantrex SW, PS & DR series
inverters. These disconnects can also serve as a central wiring point for
your system by housing a DC bonding block and/or shunt. Each disconnect
comes with one main 175A or 250A breaker with space for adding a
second breaker. Four smaller knockouts on the side can each house a 15-
60A DC breaker for solar input or DC load output. Size 21" x 10.5" x 4.8". Solar Electric Products Catalog November 2005
