Hi. I want to use my Victron Multiplus 48/3000/45 as a microinverter to Deye 12kw hybrid (SUN-12K-SG04LP3-EU) When I connect the offgrid Victron AC out to Deye (microinverter input) the Victron goes to overload and does not work. Any idea why? Are there any settings on Victron to be adjusted in order to make this work? Is it actually possible to use Victron as a microinverter at all?
You are mixing up your terminology.
Cascading inverters isn't supported, the Deye is a conventional DC inverter, not an AC coupled PV inverter which supports frequency shifting.
Even then it is way too big to be attached to that inverter.
You have attached a 12kW inverter to the output of a small 3kVA (2400W) inverter, that isn't going to work well, and yes, you would need several settings to try make this work, but you have not provided any detail at all.
Rather contact a supplier and get some professional advice.
