Connecting AC cables
DANGER
Danger to life by electric shock!
Touching live parts of the electrical
connection may lead to death or
serious injury.
▶
Turn off the storage system.
▶
Turn off the main disconnect
circuit breaker.
Only trained, electrically qualified
persons are allowed to perform the
electrical installation.
Trained, electrically qualified person only!
The storage system has two AC primary
connections: One for the utility grid and one for
the microgrid. These connections must be made
for the storage system to operate.
The utility grid port on the storage system must
be connected to either the utility meter or the
main utility panel. In either case, install a main
disconnect between the storage system and the
utility grid of equal or greater rating than the
supply feeder connection, up to 200 amps.
If you will be using a protected loads panel, design
the panel for a nominal current of 33A. The system is
connected as illustrated here:
Fig. 23 Installation using protected loads panel
Special care must be taken to ensure the
main panel and the protected loads panel are
electrically isolated from each other when the
storage system is not providing a closed circuit
between the two. L1, and L2, and N must have no
connection between the two panels aside from
through the storage system.
If you are not using a protected loads panel,
you can use the storage system’s built-in, 200-
amp automatic transfer switch to provide backup
power for your whole house. In that configuration,
the system is installed as shown here:
Fig. 24 Installation without protected loads panel
In either case, the load that will be powered by
the ecoLinx is connected to the microgrid terminals
inside the storage system. The storage system’s
built-in transfer switches will disconnect the utility
connection should the utility grid stop providing
power, and the microgrid will be powered by energy
produced by the PV array and the energy stored in
the ecoLinx ’s battery modules.
You can also connect a generator (up to 50
amps) to charge the batteries in the event they are
discharged to the point that the storage system will
not turn on and neither the grid nor solar power is
available. Any excess generator power will go to loads.
1. Install disconnect switch
Install a disconnect switch within eyesight of the
storage system to remove power from the system
during installation and service.
2. Install junction box for splicers (optional)
If desired, install a junction box to house in-line
splicers such as a NSI Tork ISR-1/0 to reduce the
size of the cable run from the distribution panel to
the storage system.
