GRID Tile
The SkyBox connects to the utility grid to charge batteries and run loads. It can also
sell to the grid, or interact with the grid in other ways if sell-back is not permitted.
The Home screen GRID tile A has several grid status indicators. The colors of
each indicator use the same general key shown in the TILE section on page 5.
o The chevron B is present when the status message C shows the unit is BUYING or SELLING.
 Chevron aimed upward: BUYING
o Message C displays the specific status of the SkyBox grid connection.
 (gray): The grid is disconnected.
 (gray): The grid is outside the grid protection parameter boundaries.
 (green): The grid is within input range but the connection timer is still running.
 (green): The SkyBox is minimizing grid input with the GridZero™ function.
 (gray): The grid is available but the SkyBox programming has disconnected from it.
 (green): The SkyBox is connected to the grid. Total activity is less than 100 watts (either bought or sold).
 (yellow): More than 100 watts of power is being taken from the grid. The chevron in B points upward.
 (green): More than 100 watts of power is being sold to the grid. The chevron in B points downward.
o D is a circular meter which advances clockwise to show the grid power being handled by the SkyBox (bought or sold)
in kilowatts (kW). The meter is fully lit when the SkyBox reaches full capacity (10 kW when buying, 5 kW when
selling).
Th
e power is also displayed as a digit in the center.

Tapping the GRID tile A opens E for a given day. The default view is the BUY/SELL tab G. It shows:
o Peak kilowatts (kW) either bought or sold that day (graphed with a pink line).
Pink dots mark the instantaneous peaks of buying and selling.
o Kilowatt-hours (kWh) accumulated (bought and sold) that day
(graph
ed with yellow and green ba
rs).
o Net daily kWh accumulated (K). This is not graphed.
NOTE: These items are graphed by time of day. The peak value
for each is also shown as a number. Tapping a colored bar at the
bottom of the screen will hide that number and graph, or restore it.
When the NET display is tapped, it replaces the daily kWh graph.
Tapping the clock symbol F changes the graph to a daily,
weekly, monthly, or yearly historical display of buy/sell activity.
The “down” chevron J opens a MORE INFO screen with:
o The present grid wattage handled by the SkyBox.
o The present grid connection status
o A command telling the SkyBox to either drop or use the grid
o The present grid voltage and frequency
Tapping the VOLTAGE VARIANCE tab H opens a screen
with average high and low grid voltages as shown.
The CONFIGURE button I leads to a
screen with
various grid connection settings.

LOAD Tile
The SkyBox uses an inverting function to convert battery (DC) power to AC output.
It can run loads in the absence of an AC source. If an AC source is present (utility grid or
generator), the SkyBox can switch to run loads directly from the AC source.
The inverting function can also work with the utility grid. It can add PV and battery power
to support loads (self-supply) if the AC supply is not large enough. It performs similar
activity for the grid-interactive (sell-back) and GridZero functions. It can also “AC couple”
power from another grid-tied inverter to the grid.
The Home screen LOAD tile has several load status indicators.
o The chevron B shows that the SkyBox is either buying or selling.
 Chevron aimed downward: Sending power to loads (POWERED, SUPPORT,
PASS THROUGH).
 Chevron aimed upward: Receiving power from load input (AC COUPLE).
o Message C displays the specific status of the inverting function.
 (black): The loads are not being powered. The Off/On button (see page 3) is set to OFF.
 (green): The loads are being powered by the SkyBox.
 (green): The loads are being supported by both the SkyBox and the grid.
 (yellow): The loads are being powered by the grid.
 (yellow): The SkyBox is being powered through the load port.
o D is a green circular meter which advances clockwise to show the power kilowatts (kW) being handled by the output.
The meter is fully lit when
the SkyBox reaches full capacity (10 kW). The power is also displayed as a digit in the center.
Tapping the LOAD tile A opens E for a given day. The default view is the TOTAL tab G). It shows:
o Peak kilowatts (kW) either consumed that day (by loads) or produced
through AC coupling (graphed with a pink line). Pink dots mark
the instantaneous peaks of consumption and production.
o Kilowatt-hours (kWh) consumed (by loads), self-supplied, or
produ
ced that day (graphed with yellow, green, and orange bars).
NOTE: These items are graphed by time of day. The peak value
for each graph is also shown as a number. Tapping a colored bar at
the bottom of the screen will hide that number and graph, or restore it.
Tapping the clock symbol F changes the graph to a daily,
weekly, monthly, or yearly historical display of load output.
The “down” chevron J opens several MORE INFO screens with:
o Percent of SkyBox load capacity
o L1 and L2 Total load and Self supply
(kilowatts of lo
ad supplied by battery and solar power)
o Today’s Self supply and Lifetime Self supply (kWh)
Tapping the L1 or L2 tabs H brings up screens with individual
daily kW and kWh figures similar to those in G.
The CONFIGURE button I leads to a screen with various
load management settings.
