Hi Anthony,
No offence intended, but it is one thing to say 7 days off
grid without issues, but were those 7 days sitting stationary, or were they moving every day?
There is a big difference between being able to sit stationary off
grid for 7 days, and being off
grid for 7 days but driving every day recharging your batteries. What capacity are the LiFePo4 batteries? What size Inverter? What output in Amps is the DC/DC Charger?
We prefer off
grid camping, only using caravan parks when we absolutely need to, and have sat stationary for up to a month without any real problems. Having said that, we were in southern NSW in April alongside a river. Our caravan has 2 x 100 AmpHr LiFePo4 batteries and 500 watts of fixed roof mounted solar panels, plus another 200 watt folding solar blanket, and a 2.2 KVA Generator as back up. There was a further 120 amps of AGM Auxiliary batteries (made up of a 70 AmpHr and a 50 AmpHr) in the towing vehicle powering a 60 Ltr. Engel fridge. On this particular occasion, the generator was used only once, after 3 days of overcast and rain.
Since then, I have replaced the 120 amps of AGM, with a single 175 AmpHr LiFePo4 Auxiliary battery and installed a 2,000 Watt Inverter into the towing vehicle. I am still approx. 50 watts short of ideal Solar Watts to Battery Amps ratio of 2 to 1.
Macca.
