Troubleshooting “Static switch”
This procedure is to be performed only as directed by Table 13 above.
1.
Navigate to the static switch screen (“Status > STSW”). Compare inverter voltage and output current
from that screen with the same data from the inverter.
Figure 87: Status screen
In the Status screen, tap the Static Switch icon (“1” in Figure 87).
The
static switch measurements screen
is displayed (Figure 88). Record the
inverter voltage
and
output current
that you see on the screen.
Then return to the Status screen and tap the inverter output tab (“2” in Figure 87). The
inverter
output measurement screen
is displayed (Figure 89). Compare the
voltage
and
current
measurements there to the ones you recorded from the static switch measurements screen. If the
difference is greater than ±3 % for voltage or ±10 % for current, calibrate the static switch.
