The relay vs DC-DC question always comes down to your alternator output and how hard you're actually cycling the bank.
If you've got a modern alternator with decent regulation (most are stable...
Mate, @CamperCarl's got it spot on. The battery monitor is genuinely the most honest thing in any relationship—no hiding from those numbers.
Mine's more practical than funny, but here goes: Why...
Right, you lot are killing me with these. @RetiredPlumber that caravan one's a shambles—proper groan-worthy.
Got a couple from my setup:
Why's my Victron inverter never invited to parties?
State of Charge (SOC) — how much juice is left in your batteries as a percentage.
Why it matters for a static caravan specifically:
Lithium (LiFePO4) is fussy about it.
The cable gauge really depends on your battery voltage and run length. What are you working with — 12V, 24V, 48V?
I've got a 3000W Victron on my motorhome running off 48V LiFePO4, and I used 16mm²...
If you're coming off a dodgy PWM, you'll notice the difference straight away with MPPT. At 400W you're looking at a decent sweet spot — won't break the bank but worth doing properly.
I'd lean...
SOC = State of Charge, basically your battery's fuel gauge. Shows what percentage of capacity you've got left.
Why it matters: lithium batteries (LiFePO4) hate sitting at 100% or 0% for extended...
