Is it of use writing to Victron B.V in The Netherlands directly re failure of a Victron Multiplus less than 2 years old. Seller refusing to even acknowledge any form of request for return or help. Seller also initially configured the unit for installation, and then a month ago supposedly corrected a fault code, following that within 12 hours of plugging into shore power unit overheated and failed. Have also tried to contact Victron UK with no response. This has been going on for 6 weeks now.
