CHARGING DELTA2 FROM MOTORHOME SOLAR PANEL.

[Mtbcol]

Lookout it's me again .

I'm going to supplement our lead acid leisure battery with our ecoflow delta 2. The leisure battery is currently hooked up to my victron mppt.

Once the LB is fully charged when we're parked up, if the delta 2 needs topping up I plan to disconnect the solar panel from the mppt ( I've got MP4 connectors before the mppt and also plan to put in a breaker as it will be easier) then connect the panel to the DELTA2 with the appropriate leads. Do I need to disconnect the mppt from the LB each time I do this, and does it matter what order I disconnect in if I do need to. I know on initial set up you don't in a particular order.

This is only a temporary set up as once funds allow again I'll be replacing the lead acid LB with a lithium.

Thank you.

Loads of options from an Alternator charger to the EcoFlow or a fused XT60 off the battery to the EcoFlow (will charge while driving) or an additional portable solar panel to the EcoFlow.

I charge my Delta 2 Max (and extra batteries) from an Alternator charger while driving and I also have 2 fold out 220w solar panels.

I also run 460ah Fogstar Lithium, but lucky for you you don’t have my misses (can come to a deal mind)

I do have 2 x 100ah Lithium batteries to sell if your interested btw

If you are disconnecting the panel from the controller and feeding this direct into the Delta(or via another controller), then leave the controller connected to the leisure battery.
The leisure battery should always be the first thing connected, and last thing disconnected.
