The Xantrex is great kit. Ours has given over 5 years of very trouble free service
now, ( well I don't call getting caught in a fire caused by faulty BEP switches its fault) even then Xantrex was right there to help us get it back in order again quick as can be. I do not know the Link 1000, we have the 2000R but they should be close enough to make some guesses.
1. Make sure you really do have a good ground from the chasis to your ships ground like it says in the book. Do not trust the third ground wire in your AC system. It must be a seperate heavy cable for this.
2. Make sure your battery
connections are good and solid and above all make sure the switch between the battery and the inverter
is a good one more than strong enough to handle the real loads. If you have a BEP battery switch just trash it out of hand and get a real battery switch. Trust me I know from 40,000 USD in damages and two sets of those switches failing what I am talking about here and if you don't trust me then how about the insurance
companies surveyor! If the battery switch ( the one that cuts power from the batteries to the unit is faulty it will go wonkie when it gets hot and either cut out or "chatter" causing major power spikes through the system.
3. Make sure the on off switch on the inverter
itself is OFF and no on by accident
. That happened to me once ( bless Thai carpenters) and took me days to discover.
Hope that helps if not do contact Xantrex my experience has been they are 100% ready to help out any way they can.
