Good morning,
I have installed on my boat a Victron ARGO FET 200. The device is connected on one side with the engine battery, on the other with 4 batteries for services.
I have the following problem: with the engine running I register 13.7 Volt on both banks of batteries. If the demand on the service batteries is high (even if for short period - i.e. the use of the bow thruster) the voltage on the engine battery drops below 13 Volt ( 12.7 Volt). This generate an alarm warning on the engine circuit ( Volvo Penta MDI system) set to run over 13 Volt. Is there any way to overcome the problem of voltage drop? Many thanks for any help.
Kind Regards
Marco
