I have the Multiplus 3000/48 inverter-charger with S.N. HQ232029J77 and I have activated the general flag for controlling the AC Input.
I use the AC load state for driving the relay. The setup is very simple and we can easily check if the inverter is working properly. The photo below illustrates the programming of the command.
When the load is greater than 1200 Watts (my load is 1600 Watts) then the general flag is activated after 5 seconds and the Input AC relay is turn in the OFF position. The grid supplies power to the loads and Multiplus is not in inverter mode.After 60 seconds I remove the load. The load is zero. Then the general flag is deactivated after 60 seconds and not in the 300 seconds of the setting. Then the Input AC relay is turn in the ON position. Multiplus is in inverter mode.
I repeated the test for 120 and 180 seconds. Τhe general flag was deactivated at 120 and 180 seconds respectively and not at the 300 seconds of the setting.
If the load is active for 6 minutes and then removed, the general flag is deactivated after 300 seconds. This is OK.
Is there something wrong with my setup above?
I can’t find detailed examples and instructions for using the general flags.
Thanks.
