The MOD3 command traffic between the monitoring application and the
inverter is transmitted in plaintext without encryption or obfuscation.
This vulnerability may allow an attacker with access to a local network
to intercept, manipulate, replay, or forge critical data, including
read/write operations for voltage, current, and power configuration,
operational status, alarms, telemetry, system reset, or inverter control
commands, potentially disrupting power generation or reconfiguring
inverter settings.
