How to Backfeed to Grid from Multi with PV

Hi,

i'm running a Multi 12/500 in my Van, combined with 150Ah LiFePo4 Batteries, MPPT and 200Wp PV.

Is it possible to feed unsused Energy back to the Grid if it's not used for Charging the Batterie?

Do i use ESS for that?


Thanks in Advance.

the option is missing, is there a must for a GX?

Yeah for ESS you need a GX.

well ok, then i'll grab a raspberry pi and see how far i get.


thanks

Doesn't work, it starts feeding, reduces the wattage and then gets back to charging. Any Ideas or suggestions where i can read?

If its installed in a van, this means you have some form of mains connector that you can unplug to drive?

If this is the case, you should not set up ESS as the plug connector can remain live for some time after disconnection.

actually i thought i would only use and activate it manully if the van is @home (like now for ex.)

but i am open for good suggestions, i'm only sad to waste the energy
