Solar Charging Leisure battery through EHU

[Robdog]

Hi, I have a Bluetti AC70 plus a 200W folding solar panel as a back up for when 'off grid', cracking bit of kit not too big not too small. Is there any reason why I should not plug the AC 3 pin output into the vans EHU socket (just as if we were on hook up) to charge the leisure battery. The Bluetti has Pass Thru charging so I could feed the AC70 via the Solar Panels at the same time. The reason for asking is that our fridge normally last about 4 to 5 days off grid then the leisure battery needs a top up.

No reason at all. I've just done this with my Jackery and 100w folding solar.
Tested the Jackery through the EHU, all works fine, so can plug solar in as it is doing that. For flexibility, I have added a solar controller with fly lead and battery connection so the panel can go direct to battery aswell

Thanks, yeah it made sense to me, can i ask what was the AC draw like on your Jackery when hooked up?

I'm no electrics wizard. When I plugged it in it was drawing 320w after 5 mins it had dropped to around 120w. The LB was about 75%, 12.4v

I think

Ok, me neither but that a useful bit of info thanks, my fridge/freezer is about 60w so i guess that should allow for some juice to charge up the leisure battery as well as keeping the fridge running.

No problem doing this.

If it's running through a consumer unit in the van the RCD may not work as expected but the MCB should operate under a fault, or the Bluetti will cut out.

Either way you should be fine .

Similar for me when I ran my AC70 through the EHU socket, although it continued to draw 320w for some time to charge LB.
There was no sunshine that day, so no solar input.
