inverter to rectifier
You will get about 320 volts DC from the rectifier.  A 30 Amp rectifier would be more than adequate, as the inverter can only deliver about 2 Amps.

Whether this is safe or not depends on how you wire things, and what you are doing with the 320 volts DC.

230 Volts AC and 320 volts DC ARE DANGEROUS if you don't know what you're doing.
