My 2018 Autosleeper Nuevo has a Sargent EC328 PSU which works fine when hooked up to a normal mains supply.
When going off grid I have an Ecoflow Max 2kWH power bank which supplies up to 2kW at 240v. This also works fine. Rather than trail an extension cable around the van I have made an adaptor cable which plugs into the Ecoflow then via an inline RCD into the external EHU socket of the van. This means I have mains voltage to the internal sockets. I can then run my air fryer, kettle, toaster etc. (although not all at the same time!) All this works perfectly. However when I try and use the microwave it instantly trips the main circuit breaker on the Sargent unit. The microwave is only drawing around 600W which is easily handled by the Ecoflow and in any case it's the EC328 which trips, not the Ecoflow.
I also have a 3kW inverter connected to the leisure battery and if I use my adaptor cable connected to this in the same way the microwave works fine.
I've noticed that when using either the inverter or the Ecoflow the Reverse Polarity light on the Sargent lights up. I've checked the wiring and it's all OK so I'm guessing it's due to the lack of a proper earth. Despite this everything works except the microwave when using the Ecoflow.
Any ideas what might be the problem with the Ecoflow/Microwave combination?
