Self Supply Setpoints - Generac Power Systems PWRcell X7600 Series Owner's Manual

General Information
See Figure 2-13. When local demand exceeds available
solar-generated power, the battery supplies power to
support local loads. If the building requires more power
than the battery and solar can provide, then the excess
demand is drawn from the grid.

Sell
Sell mode commands the system to export all available
power to the grid. Any connected batteries drain to the
grid until their state of charge reaches the Min Arbitrage
setpoint. Once a battery is depleted to this point, it will not
charge again until the operational mode is changed. See
the Generac PWRcell Battery Installation Manual for
more information.

Table 2-3. Self Supply Setpoints
Target Maximum Import Power
•
Maximum power imported from the grid at any point.
•
When the overall building load exceeds this setpoint, the inverter will supply
additional power from the battery and solar array to keep grid import power
below this level.
•
This maximum is not guaranteed. If not enough battery and solar power is
available to cover the load, then the grid will supply the additional power.
Target Minimum Import Power
•
Use this setpoint to charge the battery from the grid.
•
If the overall building load is less than this setpoint, the inverter will import
power to the battery to keep the grid import power up to the setpoint.
•
If the building load is above the setpoint, the inverter will not import
additional power to charge the battery.
•
This minimum is not guaranteed. Once the battery is full, grid import power
may fall below this level.

Self Supply Setpoints

The TargMinImprtP and TargMaxImprtP setpoints allow
the building to deliberately import power from the grid
within certain limits. This is useful for specialized
applications, such as peak avoidance.
These setpoints are relevant to Self Supply mode only,
and are only used for specific applications. See
Table 2-3: Self Supply
Description
Zero Export
In some areas, solar PV systems are prohibited from
back-feeding the AC grid. For these applications, enable
Zero Export. With Zero Export enabled, the inverter does
not send excess solar power to the grid. Instead, the
system limits solar power generation such that it exactly
matches the power consumed by local loads, resulting in
no exported power.
