200 watts solar on the roof would also prove useful.
I have almost 1100 watts.
Wow I am surprised you need more charging capability. Must camp in poor solar conditions at time.
Do you carry a generator? Could consider running the generator en-route.
Does the lithium not have its own BMS to protect it? I really doubt the alternator direct would cause any issues. Put a volt meter on your truck 12v system and drive around a bit to monitor/evaluate conditions.
Just some random thoughts to cover the bases. Inverter off the alternator should work well.
Typically we camp in very good solar and our system provides what we need. We don't carry a generator and have no desire to do so. My generator compartment is where our lithium battery is housed.
The alternator charging would be a secondary charging source for long periods of inclement weather or when we are using a lot of air conditioning. I would feel more comfortable doing deeper battery discharging knowing that the alternator could add charging the following day while we travel in addition to the solar charging. Even with a large solar array replacing 500+ AH can be a challenge in a moving vehicle. Typically the solar contributes 30-65Ah I feel we could double that or better while we are driving.
It just something I am kicking around at this point. As I have mentioned a few times I was thinking about adding an inverter to the truck anyway and past that carrying the circuit to the camper seems simple.
I was just curious if anybody had set up a system like it, how it worked for them and any install advice they might have.
