Combining MultiPlus II and EcoFlow DeltaPro

Dear all,

I actually have my MultipLus II GX combined with Pylontech batteries, actually no solar. To otake advantage of the different electricity costs during day and night I an preparing to use it as ESS. Consuning battery electricity when grid electricity is expensive and charging from the grid when it is cheaper. (Until my PV is up and running).

I have an EcoFlow Delta Pro which I use when I am travelling with my RV. Though I am not travelling all the time I would like to benefit from its large battery capacity and connect it to my ESS system.

Even though the Ecofloy has an inverter for 230V, I suppose it is not that easy to Connect it to the AC-In of the MultiPlus II parallel to the Grid.

Though my idea to realize a good and not too expensive solution actually is to use a DC/DC converter to level up the Anderson 12V output of the EcoFlow Delta Pro to 48V, then connect a 48V PV battery charger to the battery.

What do you think? Does anybody have a similar installation? Could it work?

Thank you in advance!

the EcoFlow Delta Pro ha 3.6 kWh capacity.
For about 730 EUR you get a 3.5 kWh Pylontech US3000C which seamlessly integrates into you existing system.

I would not spend money and time to build the not designed integration of this two worlds.
