I have a boat with 2 outboards connected to a AGM starter bank. From here I would like to charge my lithium bank using 2 x Orion TR smart 12/12-30.
I have read about the voltage settings for starting and stopping. All good so far.
The problem starts if I run only one of the outboards (trolling etc) both Orions will start and overload the one 50ah alternator.
Is there a signal from each outboard I can connect to the Orions on/off port? What type of signal is accepted? On / off voltage or just short cutting? Do not know what the Yamahas provide.
I also have the Cerbo Gx connected to the NMEA 2000 so maybe the relays can be used if the cerbo understands which outboard is on/off?
For info I have the following equipment;
- 2 x 100ah lithium batteries c/w bms (aio)
- 2 x Orion Smart 12/12-30
- Cerbo GX
- Smart Shunt
- Smart MPPT 100/30 + solar panels
- 2 x yamaha f225
Hope there is someone out there with the same setup that can share their setup.
