Disappointed
I have gone through two of these units and both have died with the same issue. They overheat. I am not able to charge at over 6 A without the unit overheating. Anything over that and the unit will overheat in about 20 minutes.
The support team is extremely helpful once you get them on the phone but both times they have come to determine that the unit needs to be replaced. There is a repair program but even having two on hand the tech team says that it’s not worth the cost to go through a repair.
Now that the second unit is having this issue, I’m looking for a different alternative than just replacing.

Nice piece of equipment
This is a heavy duty, well made combo charger/inverter. Mounting hardware very sturdy and easy to use. Everything worked from the start with no issues. A big improvement from the aging separate charger and inverter that it replaced. The remote Mastervolt controller allows monitoring of everything and turning the inverter off/on. Got rid of a lot of cables!

Questions
Where are these made (i.e. country of manufacture)?
US company Brunswick owns Navico who owns Mastervolt. Currently the equipment is manufactured & engineered in the Netherlands.

good for lifeph batteries?
My boat came with a complete MasterVolt system installed. I was replacing a unit that failed after 3 years. In general, although the system does work well, I find dealing with MasterVolt support frustrating and if I was purchasing new equipment would look elsewhere.
