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.
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.
