Sell Status

Sell Status messages describe conditions relating to the inverter's grid-interactive mode. This
screen is viewed using the Home screen's soft keys on a MATE3-class system display. (See
the system display literature for more instructions.) One or more messages will display Y (yes).
If a message says N (no), it is not the cause of the disconnection.
If the inverter has stopped selling or charging unexpectedly, this screen may identify the reason.
More often these messages are used by a normally functioning inverter to identify external
conditions that are preventing selling or charging. (If nothing has stopped, the messages will
indicate that as well.)
The acceptable limits for AC source voltage and frequency are controlled by the Grid Interface
Protection settings, which are shown on page 66. If the AC source exceeds these limits, the
inverter will stop selling and display the appropriate code. (At the same time it will disconnect
from the utility grid, with an appropriate message in Table 10 as shown on page 54.) After the
source returns to the acceptable range, the screen will begin its reconnection timer (with a
default setting of five minutes). When the timer expires, the inverter will reconnect to the utility
grid and begin selling power again.
If the AC source is unstable, it may become unacceptable before the timer expires. This may
cause the timer to continually reset. It is possible for brief fluctuations to occur that are too fast
to be seen on a DVM. If this happens, the appropriate message will still appear on the system
display for a short time to help troubleshoot the problem.
Additionally, undersized wires or bad connections can result in local voltage problems. If a
Voltage Too Low or Voltage Too High message is accompanied by voltage changes that do
not appear at the main utility connection, check the wiring.

Definition
The Grid-Tie Enable command has been set to N (no).
All utility grid conditions are acceptable. The inverter is
running a timed test during which it confirms the grid quality.
The timer is shown on the screen. At the end of that time,
the inverter may be ready to sell.
The utility grid's AC frequency is below the acceptable range
for selling.
The utility grid's AC frequency is above the acceptable range
for selling.
The utility grid's AC voltage is below the acceptable range
for selling.
The utility grid's AC voltage is above the acceptable range
for selling.
The battery voltage is below the target voltage for that stage
(Float, Selling, etc.). No excess energy is available to sell.
