Hi all,
I have a smart alternator on my Yanmar 4jHT110 engine on Jeanneau 51 Yacht. . I have had previously regular house batteries and now all replaced with 4x200amp Victron smart batteries with LynxBus/distributor and 3kwa MultiPlus, with Solars connected trhu MPPT controllers. 220 charging of house batteries goes thru Multiplus and other batteries 220 charging goes thru another 220 cristec battery charger. All of the solar charging and 220 charging setup works perfectly. Now the way currently the charging from Alternator is setup as follows. Boat had a Cristec Battery isolator with 3 outputs(mosfet). 1 output is going to Engine (120amp lead acid), one to Bow Truster batteries and one was previously going to lead acid service batteries. Since now all house batteries changed to Lifopo4 from Victron, the current setup is that 3rd output from Cristec battery isolator is connected to Orion DC-DC Non isolated TRSmart 30amp charger. I have 3 of these in paralel so i can provide 90amp chargin capacity and these Orions feeds into the Lynx BMS. Orions are right next to the isolator and from Orions to the BMS its less than 2m.
The engine and bow Truster are charged perfectly with no issues. Issue I have is Orions detects in their input voltage drop every 5seconds (all one by one) or so and they stop charging for 1sec and than starts recharging again and does this continuously. What have we done wrong here in the configuration we can not seem to find. The setup is done by Victron service. Any ideas or highly appreciated.
