I implemented a solution using Multiplus assistants to be able to set an input current limit lower than the minimum value of 6A (Multiplus II 48V 5KVA). Since this minimum value of 6A only exists when Power Assist is enabled, I disabled Power Assist so that I could set a lower value to be used by Power Control, and I created assistants to ignore the AC input when the AC load is higher than the desired limit (so as not to exceed the AC input limit, since Power Assist had to be disabled). This solution is working well, however, when I need to change the current limit on the AC input I will have to redo the settings and assistants programming in VE Configure. That’s why I wanted to automate these settings using Node Red. To do this, I would need to enable Power Assist when the current limit on the AC input is set to a value greater than or equal to 6A, and disable Power Assist when a limit lower than 6A is set. The problem is that when Power Assist is enabled, I am not able to get the current limit reduction at the AC input to a value lower than 6A, because the limit value automatically goes to 6A when trying to set a value lower than 6A, and the reduction attempt is not even detected in the Node Red flow that I am creating. Is there any way to get this value when trying to set a limit lower than 6A and Power Assist is enabled?
I implemented a solution for this problem that is not perfect, but it is satisfactory: turning off PowerAssist when the current limit on the AC input is equal to 6 (which is the minimum value for PowerAssist on my device). This solves the problem because, when PowerAssist is disabled, you can read the actual value configured for the AC input current limit. When PowerAssist is enabled, if you configure an AC input current limit value lower than 6A, you cannot read what that value is; what you get when reading the AC input current limit is 6A. But the actual configured value is not lost, and if PowerAssist is disabled, you can read that value. So, disabling Power Assist when the current limit is equal to 6A makes the actual configured value appear, if it is lower than 6A. This solution is not perfect because I lose the possibility of using PowerAssist with the AC input current limit set to the minimum value of 6A, but I can use it with 6.1A, so it is not a significant loss. Ideally, the actual AC input current limit value would be available on the Node RED node in some other variable, so that this value could be read even when Power Assist is enabled.
