Scan 512 or less inverters connected via
Ethernet.
An error occurs during firmware
update (inverter reset) via Ethernet
when multiple inverters are connected
in line topology.
The relay station is reset during firmware update
and the communication with the subsequent
inverters is disconnected.
Set the reset time longer to reset all the
connected inverters simultaneously.
An error occurs during firmware
update via Ethernet when multiple
inverters are connected.
For firmware update when multiple inverters are
connected, a communication delay occurs due to
relay delays.
