4.5.2 – Making AC Connections

AC Landing Points – Terminal Blocks

The AccESS is equipped with multiple knockouts on either side of the unit for accessibility to the Sol-Ark’s AC

connections. All AC connections are rated at 120/240 VAC. The bi-directional grid port can also support two

out of three phases of a 208 VAC grid connection (the two phases being L1 and L2, 120° out of phase).

The Sol-Ark equipment includes the following:

• Bi-directional Grid Port (AC In/Out): 63A double-pole breaker

• Bi-directional Generator Port: 63A double-pole breaker

• Load Output (AC Out): 650A double-pole breaker

Figure 14.0 below shows the “Grid,” “Generator,” and “Load” connection locations. Also highlighted are the

neutral and ground AC terminal blocks.

Grid AC Wiring

1. Install a double pole 50A breaker in the main house breaker panel. Best practice dictates that this 50A

2P breaker be installed at the opposite end of the busbar from the main breaker (typically at the

bottom of the main house breaker panel).

2. Include an External AC Disconnect (with handle) between the 50A 2P breaker in the main house

breaker panel and the Sol-Ark’s “Grid” port.

• The External AC Disconnect must be sized larger than 50A and include a knife blade switch.
