Reading the Meters Screen
The Meters screen displays total system power production, grid voltage and
current status, and load voltage and current status.
To view the Meters screen:
◆
On the XW Inverter/Charger setup menu, highlight “Meters” and press Enter.
Grid Support There is AC input from the utility and the XW Inverter/Charger is supporting the utility grid by
supplying additional power to the critical loads.
The XW Inverter/Charger supports the utility grid by limiting the power drawn from the utility
to less than 10 per cent of the load demand. This mode is desirable for using excess energy from
auxiliary DC sources like PV, while still maintaining a charged battery bank. No power is sold to
the utility in this mode.
The XW Inverter/Charger enters this state only when the Grid Support is set to “On” and battery
voltage is above the Grid Supp Volts setting. See “Grid Support Settings” on page 3–16.
Load Shaving There is AC input from the utility, and the XW Inverter/Charger is supporting the utility grid
when the current required to power the loads rises above the Load Shave Amps setting between
the Load Shave Start and Load Shave Stop times set on the Grid Support menu.
Many utilities impose a surcharge on their customers based on the peak load used by a facility.
When load shaving, the XW Inverter/Charger uses stored DC capacity to reduce the peak load
on the utility grid and keep current draw from the grid equal to or under the Load Shave Amps
setting. The XW Inverter/Charger enters this state only when Grid Support is enabled, the Load
Shave time window is valid and the load draw exceeds the Load Shave Amps setting. See “Grid
Support Settings” on page 3–16.
Search Search Mode is enabled and the XW Inverter/Charger is standing by, waiting to begin inverting.
See “Using Search Mode” on page 3–8.
SellToGrid The XW Inverter/Charger is grid tied and selling power to the utility grid. Both Grid Support
and Sell must be enabled in order to sell power back to the utility. See Table 3-1 on page 3–2 and
“Grid Support Settings” on page 3–16. All configurations must comply with local and national
electrical codes.
Standby The unit has been placed in Standby mode using the “Mode” setting on the SCP Setup menu or
the Standby button on the SCP or using the Standby key press (On/Off and Equalization) on the
Inverter Information Panel.
Passthru The AC connected to the AC1 or AC2 input is passing directly through the XW Inverter/Charger
to the loads. The batteries are not being charged in this state.
Equalize Equalization has been turned on and the XW Inverter/Charger is equalizing the batteries after
completing a full charge cycle.
