Terms Used
  • All-in-One: The inverter has a built in Solar input. It does not require an external Charge Controller or Grid-Tie (GT) Inverter.
  • Grid Support: Ability of the inverter to send excess solar power to the load if the Batts are fully charged.
  • Enhanced Grid Support: Ability of the inverter to do Grid Support and blend a percentage of battery energy with the excess solar energy to the load, while completing a full charge cycle of the batts.
  • Priority Grid Support: Ability of the inverter to do Grid Support and blend a percentage of battery energy with the excess solar energy to the load without completing a full cycle. Also known a Self-Consumption Mode.
  • Peak / Load Shaving: The ability of the inverter to use battery power to supplement grid power when a peak is detected (with RTC).
  • Stackable: The ability to add additional Inverters in parallel to increase inverter output.  Note: The Stack Limits (max output).
  • Sell to Grid: Exports excess/available DC power to the grid (Nett-Metering).
  • 3-Phase: The ability of the inverter to be configured into a 3-Phase output (usually 1x inverter per phase   or   multi-inverters per phase).
  • AC-Couple: The inverter can work in an Off-Grid configuration with a GT inverter connected on the AC output to supply the load and batts (at 95% – 98% efficiency). Typically for Day-Time Loads.
  • RTC Programming: The inverter programming can be configured using the Real Time Clock (RTC). For Advanced Programming functions.
  • Load Control DB (iSense): The ability for the inverter to control contactors (iSense) on a DB Board. To disconnect non-priority loads on loss of AC in.
  • Gen Start: The inverter can send a signal to a 2-wire or a 3-wire standby generator to Start/Stop. For backup AC battery charging & load supply.
  • Home Automation Ready: The inverter has the ability to communicate on common Home Automation protocols. Can pass performance data and control.
  • Ext Relay: The inverter has external relays which can control various external devices (via programming configurations) e.g. ext. fans, load control, generator start/stop, etc.
  • Li-ion Ready: The inverter has the ability to interface to a Lithium Ion Battery type.
