I expect Trev did try to load it, but you know how unreliable Linux is.

Could have done that Trev apart from 2 points

1. I’ve no idea what your talking about
2. My 4x4 doesn’t have hab batteries.

Thought it was your van, please pardon the fool i am.

You ain’t no fool Trev, natural mistake mate.

My 4x4 struggled to start after I left it for 6 weeks while away in the van on and off (needed to connect another battery and a power pack) and there’s no mains at the storage place. I’m off again soon and since I had a spare 125w panel and a victron MPPT in the garage thought I’d use them.

I also spend lots of time at race meetings and doing wildlife photography so use the EcoFlow a lot.

My thinking is a 120w panel and an MPPT will keep the battery in good condition and extend the EcoFlow’s life.

I’m also booked on a ferry to Spain soon and I’ve no idea how long I’ll be away and a new battery for the 4x4 is a costly option.

A 40/50w panel will be more than required, simple to wire the regulator with a ciggy plug and plug it into the ciggy socket, leave the panel inside the w screen pointing at the sun mid day.
A cheap pwm at a few bucks will do what you want, no requirement for heavey cables at low wattage.

But, I’d have to buy such a panel rather than use what I have, and the ciggy plug is dead when the ignitions off and the 4x4 can only be parked facing East behind a hedge or facing west when in the storage area.
