inverter output frequency

I'm using US power (230v @60hz) and I plan to install a quattro 230v 5k with my 24v battery. Question is, even if I'm supplying 60hz to the inverter/charger from shore, can I program/set the inverter to outupt 50hz to my boat? (it's French built but now here in the US). Thanks for your help.

If you install a Multi or a quattro unit and set it to be 230v 50Hz then when 230v 50Hz is connected the passthrough will be 230 and 50Hz and it will charge your battery.

If the 230v 50Hz is disconected then the inverter will supply 230v 50Hz by using the Battery


then if the AC input becomes 230v 60 Hz the inverter will sync to the 60Hz and the Passthrough will be 230v 60Hz to the whole boat and the Battery will be charged.

Now as soon as the 230V 60Hz mains power is diconected then the inverter will take over at 230V 50Hz by using the battery thus the boat will go back to the default 50Hz setting in the inverter


If you do the reverse ie set the inverter to be 230v 60Hz then the same applys as above but when the AC in is not connected then it will be suppliying 230 v 60Hz by using the battery



Same applies if you have the 120 volt Multi or Quattro version as well

When the Quattro is in inverter only mode (bypass relay open) then it will output 50Hz. When mains is present and the bypass relay closes then the 60Hz will be passed through to the output.

The only way around this is to have a separate charger to charge the battery bank from the 60Hz supply whilst the Quattro inverts at 50Hz.

Can't what @miami337 want work with 'Ignore AC'?... charger accepts 60Hz and the inverter is always running outputting 230v 50Hz?

yes it will, if you ignor ac 1 in and thats 60 Hz then the output will be 50z as soon as you turn the AC1 in on then it will sync and the output would become 60Hz, then turn AC1 in off and the inverter will change back to 50Hz

Yes, but then it will not charge. It is not possible for the converter to invert and charge at the same time.
Pass AC through and charge or ignore AC and invert.

I'm sorry, but now I'm a bit confused too.

From where the inverter takes power if we use 'Ignore AC input' VS, battery or grid?

This thread went no where. :-) I am interested in the answer as I have same issue.

Is is not possible to configure all AC loads to run off the inverter and the charger running while connected to shore power or generator running?

What is the draw back to this configuration fully understanding there is risk of running batteries dead if not connected to shore power or a generator? Would this put more strain on the batteries if the AirCon is running while shore power or generator are running?


Thanks


It's not possible if the input is 50Hz and the output must be 60Hz, or vice versa, no.

The device only operates at one frequency for either or both functions.
