Generator Will a generator be used:
❐ Voltage Output Requirements
(120 Vac only, 120/240 Vac, or 240 Vac only)
❐ Auto-Start or Manual-Start
See “Generator Considerations” on page 2–19 for additional information.
Additional
equipment
What additional equipment is needed:
❐ Remote monitors, interface cables, stacking cables, DC charge
controllers, auxiliary load controllers, T240 autotransformers etc.
See “Additional/Optional Equipment Considerations” on page 2–22 for
additional information.
System Output Requirements
Determination Determine the inverter output size requirements by calculating the
maximum, continuous capacity and surge (inrush current) capacity the
system will demand.
• Add all potential loads which would be on at once to determine
continuous power requirements.
• Add the surge current of all loads which might start at once to
determine surge requirements (e.g., washer spinner, waterpump and
refrigerator compressor could all start at once).
More information See Appendix C, “Understanding Amp-hour Requirements” for
assistance in determining the System Output Requirements.
System Input Requirements
Determination Determine the input requirements based on the output requirements. In
other words, is grid power available or will renewable energy equipment
be used? Will a generator be used to supplement or backup the other input
sources?
More information See “Generator Considerations” on page 2–19 and Appendix D,
“Generators” for additional information regarding using generators for
system input.
Important: Auto-start generators require the addition of the GSM to enable
the inverter to control the operation of the generator.
