I have recently purchased a Phoenix 12/50 (1+1) 240V Smart battery charger and installed it on my boat which has 480AH of AGM batteries. I used to have a Projecta 50A charger which failed. I run the charger from either mains shore power at the marina or from a 2000W inverter generator when out sailing. After three days of charging (1 hour per day) from my original generator (a generic version of the Honda 2000i) it failed - it showed overload and stopped generating AC. However even after I disconnected the load I still couldn’t get the generator to run again. The engine runs fine but within two minutes of starting it the AC overload light comes on and the AC circuits cut out. Numerous resets and restarts don’t change this.
So I came back into port and borrowed a generator from a friend to head out again. This is a fairly new Yamaha EF2000is.
On the second day of running this generator it started labouring and the AC cut out though it didn’t show overload. Now the generator will start but runs very slowly and won’t produce power, with the engine cutting out after about two minutes.
I know this isn’t a generator trouble shooting site but my question is - could my Phoenix charger be causing these generator issues as it seems too strong a coincidence that two otherwise perfectly fine generators have failed within hours of having the Phoenix charger plugged in- after years of successfully running other chargers in this way.
Using quality clean fuel so this is not the issue. I am in Australia if this influences frequencies etc.
Would be interested in any suggestions or advice!
