I have a question regarding my setup, i’ve build in our RV a system with a Multiplus 1200 and 200ah superpack, when i connect 1000w load on it it almost immediately shuts down (shunt display is also off). When the load is gone the system is starting up again after a while…I don’t know if it is related but when the charging is on the multiplus makes some buzzing noise like a transformer on load..
Since thats what it contains, a toroidal transformer. Im expecting it to make roughly the same noise when inverting since its the same transformer being used in both directions.
