I have taken my less than one year old Magnum 2812 back to the factory twice to have them run a check on it and they are very quick on the turn around. They are located just 10 minutes from my Boat, in Everett Washington
. Quite a big operation right across the street from the Boeing Everett plant, with really nice people.
The first time I took it back ( my fault for crossing up the wires on install and smoking the controller board) they replaced the board and had it back to me the next day (no charge). The second time I was not sure why the SOC stopped working properly and I took in the ME-BMK Battery Monitor
in with the Inverter and they gave me a new ME-BMK monitor (no Charge) due to a problem they found with it. The inverter checked out fine. I got a call less than 12 hours later to come pick it up. They even put the inverter back in new packaging for me to transport it.
Excellent service. I have the same set up in my 42 foot motorhome and never had a problem with it.
Definitely a great company to work with on repairs.
