As stated in my marine configuration my starter battery is getting drawn down under system load lower than the Input Lockout setting on the Orion XS DC/DC charger and throwing low voltage alarms.
The config:
- 12v agm starter battery (alarm setting of 11.7v) (4 years old but seems to function fine under all tests)
- 2x300 AH off brand lifeP04 batteries
- 1x550w rigid solar panel
- Victron Smartshunt
- Victron 50/100 Mppt charge controller
- Victron Orion XS 50a DC/DC charger
No trouble staring YET, but given we are often in far away bays and anchorages I don’t want to have to rely on the backup battery starting booster I have just in case.
The setup had an starter battery isolator, but I was instructed by victron to design that out and rely on the input voltage lockout setting.
I have attached a couple of settings screen shots in case that is helpful.
Any help appreciated.
