FX-Class Inverter Data Stream
900-0137-01-00 Rev A 7
EXAMPLE:
A grid-interactive inverter has a SellRE setting of 25.6 Vdc and 10 amps (1200 watts) of AC output load. DC
sources contribute 480 watts to the battery. The inverter maintains the battery at 25.6 Vdc by converting the
excess 480 watts of DC power to AC. The inverter mode displays Support with the Inverter Current meter
showing 4 amps (480 watts) of production. The Buy Current would show 6 amps (720 watts), for 10 amps
(1200 watts) of total AC load current. If the AC load was removed, the inverter would have Sell Enabled as the
mode, and show 4 amps of Sell Current.
Error Codes: This is an ASCII expression of an 8-bit byte, displayed in
values ranging from 000 to 255. Each bit represents a different error as
shown in Table 3. If more than one error occurs, the values are additive.
For example, an overtemp error and backfeed error would return an ASCII
value of 132 (a binary value of 10000100).
AC Modes: This represents the status of the AC input. The range is 00 to 99, but
only three states are in use. No AC means that no AC source has been detected by
the inverter. AC Drop means that AC is present but the inverter is not allowed to
accept it. AC Use means AC is present and valid, and the inverter will utilize it.
Battery Voltage: The DC voltage as measured at the inverter’s battery terminals. The range is 000 to 999,
incorporating one decimal place. For example, a 24.8 Vdc battery voltage will be sent as ‘248’. The resolution of
battery voltage is 0.1 Vdc for 12-volt systems, 0.2 Vdc for 24-volt systems, and 0.4 Vdc for 48-volt systems.
