Opening Conduit Knockouts - SolarEdge StorEdge Installation Manual

Opening Conduit Knockouts

Safety Switch: d isconnects both the positive and negative conductors of the PV and the positive and
l
negative conductors of the battery.
Backed-up Loads AC Breaker: Main AC breaker for the backed-up loads. Ensure this breaker is UP
l
before staring up the system.
Bypass Switch: This switch bypasses the inverter functionality in case of inverter malfunction.
l
Maintaining p ower to the backed-up loads is enabled by connecting the loads directly to the grid.
There are three switch positions. The following table describes the functionality and use of each
position:

Opening Conduit Knockouts
This step may be performed after or before mounting the inverter.
The knockouts for AC grid, PV DC and battery DC are already open. If required, use this procedure for
opening additional knockouts.
For AC connections you can use one of the following conduit openings options:
Option 1 - Connect the AC grid and backup loads wires using the AC opening (knockout already open;
l
no need to open an additional knockout). In this case use minimum 1" conduit for inserting all wires.
Option 2 - Use two separate conduits: minimum 1" conduit for the AC grid connection and 3/4"
l
conduit for the load backup connection. In this case, an additional knockout should be opened for
the backed-up loads.
To open conduit knockouts:
1. Move the StorEdge Connection Unit s afety switch and the inverter ON/OFF switch to OFF.
NOTE
When the StorEdge Connection Unit safety switch is OFF (for example during maintenance) it may
be locked to prevent safety hazard:
1. Move the StorEdge Connection Unit safety switch to the Lock position.
2. Insert the lock through the knob opening and lock.

Use this mode at normal operation.
The backed-up loads panel is connected through the software
controlled switches to the AC grid (during normal operation), or to the
inverter (via auto-transformer, for backup power).
Using this mode disables the backup functionality.
The backed-up loads panel is connected directly to the AC grid through
the bypass switch. Use in case of inverter malfunction.
