Sell Status

Sell Status messages describe conditions relating to the inverter’s grid-interactive mode. This screen is

viewed using the MATE3 Home screen’s soft keys. (See the MATE3 manual 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 69. 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 60.) 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.

(no).

Qualifying Grid

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.

Frequency Too Low

The utility grid’s AC frequency is below the acceptable
range for selling.

Frequency Too High

The utility grid’s AC frequency is above the acceptable
range for selling.

Voltage Too Low

The utility grid’s AC voltage is below the acceptable
range for selling.

Voltage Too High

The utility grid’s AC voltage is above the acceptable
range for selling.

Battery < Target

The battery voltage is below the target voltage for that
stage (Float, Selling, etc.). No excess energy is available
to sell.
