Step 3: Wire the L14-30P based on the following:
120V Model:
• Connect L1 to X
• Connect N to W
• Connect Ground to G
Always ensure the voltage measured between X and W is 120V.
120V/240V Model:
• Connect L1 to X
• Connect L2 to Y
• Connect N to W
• Connect Ground to G
Always ensure the voltage measured between X and Y is 240V.
Step 4: Turn on generator or grid power.
BOTH PLUGS MUST BE FED BY SAME SOURCE AND PHASE
Each plug has a 30A breaker to ensure no more than 30A is drawn per plug. Ensure that the phases
are matching.
Single 120V 30A Input:
When charging the Power Tower system using only a single 120V 30A input, ensure that the
charging rate and power drawn from the load (home) is less than 30A.
3.5 Automatic Generator Start (AGS)
The two-wire connection that is provided with the Power Tower allows for automation of a backup
generator when solar power is insufficient. The two-wire system closes a relay when a low voltage
scenario is detected and opens when the batteries have reached a higher voltage.
AGS relay ON: 51Vdc
AGS relay OFF: 54.6Vdc
