I have a phoenix smart charger installed in my boat and am trying to run a 650 watt Yamaha 230v generator. I keep getting over #18 Controller over current shut downs from my victron unit. The odd thing is sometimes if I keep unplugging and resetting the ac breaker on my gen set I can randomly get the system to work and charge for several hours. But it will only charge around 25amps reliably if I up the amperage it shuts down on me. Anybody know why this is happening? What do I need to do to get this system to run reliably? Do I need a voltage regulator in line between the generator and phoenix smart charger?
Yes 650va at 230v and 50amps at 12volts but I’ve never gotten the system to put in more than 35 amps before shutting down. I have toggled down my phoenix charger to put only 25amps into my battery bank. But it’s still showing the #18 error. It seems to me like more of a problem with the generator giving the phoenix charger to much or to erratic of voltage and it overloads the system and puts out the #18 error message. It’s just strange to me how if I mess with it for a while every once in a while I get it to accept the charge current and it works it’s just very erratic and time consuming sitting there unplugging and plugging the cord back in over and over again.
