Prosine Problems

In March 2010, you reviewed inverters and chargers and gave the Xantrex Prosine 2.0 outstanding marks, which made me happy because I had one. What you could not have tested, perhaps, is the fact that the remote panel that enables all the functions is a lemon. I have had to replace mine twice within a year. Surfing the Internet for solutions revealed that the problem is epidemic. Perhaps an update on your review would be timely.

Incidentally, the remote panel can be used to configure the system to work without a remote panel; however, one needs a working remote panel to do that.

Xantrex reported receiving a “few service calls” about the remote panel, and “on a rare occasion,” the panels were deemed defective. The company attributed the panel failures to external factors like stress from electromagnetic fields and surges on the AC/DC side, which can reduce the panel’s life expectancy.

Xantrex recommends that anyone with an ailing Prosine 2.0 remote panel first try disconnecting the cable port on the panel back and let it sit for 5 minutes to reset, then plug it back in. If that doesn’t fix the problem, check the phone cable and connectors at both ends, and replace any that show signs of corrosion or dirt on the contacts. If all else fails, contact Xantrex customer service via email at
