What happens if a load exceeds the AC input current limit?
If the load exceeds the AC input current limit the Multi will start inverting in parallel with the external AC supply and will provide the extra current needed. Note: When PowerAssist is enabled there is a minimum AC input current limit depending on the device type. Setting a lower limit than this minimum will result in the minimum limit.
Can I change the input current limit on a GX inverter?
Yes, if you go to the inverter on the GX, it has an input current limit setting, you can change it there. Look at my screenshot above. Watching this thread with interest as I’ve just had my system installed and o served the same thing; except, I am using the ET112 energy meter at the grid incoming point, not a CT clamp.
What happens if the input current exceeds veconfig level?
1) When the input current (loads in house plus MP-II charger) exceeds the level set in the Venus GX (or via VEConfig in the General Tab), the MPII inverter starts up and assists the grid during a ESS schedule charge session. I've overcome this by using Node Red to switch off the inverter during the schedule charge window, using TCP Modbus.
Can the input current limit be changed if not enabled?
If not enabled, it cannot be changed. The use case is to typically leave it unchecked in stationary applications, as well as inputs connected to a generator, since for them the input current limit is a static value and defined during installation.
What if a grid load exceeds 50A?
Set the Grid current limit to the capacity of your grid connection (say 100A) It will then allow for loads of greater than 50A. I too have the same issue; During a scheduled charge (SOC target set to 100%), if the grid load exceeds 32A then the MPII reduces or stops charging the battery.
What is a safe value for a power inverter?
10.3.9. Assist current boost factor This value is normally set to 2. This is a safe value because any small peak will be compensated by the inverter and the excessive power will not overload the input circuit protection.
