Setup:
400 watts of solar on the roof, 4 100 watt renology panels.
WattHour 300ah LiFePO4 battery.
Victron 100/50 mppt controller
300amp smart shunt.
600 watt pure sine inverter.
WF-8955PEC Converter
Went camping for 9 days. Battery with solar lasted the first few days before I needed to run the generator.
Problem seems to be that the converter gets no where close to fully charging the battery off the generator. Or maybe the smart shunt isn't reading battery percentages correctly?
The invter auto shut off off when the voltage Got to around 10.75v overnight. (smart shunt said the battery was around 40% if I remember correctly, although I would think it's about dead at this voltage). Shoulden't show the battery state as much lower?
The Factory Converter (WF-8955PEC) did seem to charge the battery fairly quickly off the generator at that point but then tappered down to almost nothing when the shunt was telling me the battery was at around 55%. The solar isn't producing anything close to 400 watts so I then had to pretty much just constantly run the generator for the rest of the trip. Much worse than when I had Lead Acid Batteries and no solar asd theyh would charge up all the way off the generator.
What should should I buy to fix the charging issue? A new converter? A dedicated victron charger that can interact with the shunt and solar? Also, how can I better calibrate my smart shunt so I know what the state of the battery actually is?
There is 6 awg run to the battery from the converter, probably about a 10 foot run. Since I ran 4awg to my inverter years ago, I'm planning to re-run with 4awg to a distro block (about 3 feet to the block) that will then utilize both the 4awg and 6awg connections. That should help with voltage drop a little, but I dont think it will slove my problem.
Can I just install something like this? https://www.victronenergy.com/chargers/blue-smart-ip67-charger-waterproof#downloads And connect it to the 4awg run I already pulled? The battery is mounted to the tongue of my trailer as I do not have a good location for it inside the tailer.
Or should I simply get a different converter?
