I have a 26 ft sailboat with a 200 watt 20 volt solar panel that will go to a victron 100 / 30 MPPT charge controller. Then from the starter battery to my house Bank I will have a victron Orion 24/12-30 DC to DC charger.
My house bank will be one 12 volt 300 amp hour LiPo battery.
My question is this, do I send the power from the charge controller directly to the starting battery, or can I send it directly to the house battery at the same time that the starter battery is connected to the house battery via the DC to DC charger?
Thank you in advance!
If you are wanting to keep your house battery charged then connect it to the house battery.
Thank you LX . So I don’t have to worry about the amperage going in the house battery somehow damaging the DC to DC charger when it and the starting battery are up line from the house battery?
No, you won’t have to worry about that at all.
The DC to DC if set correctly doesn’t activate until the input (starter) is above the correct voltage.
The mppt will stop outputting power when the house battery is full anyway and is not absorbing more.
Awesome. Thank you!
