GRNbms on VAG MEB battery 350kW plus, DEYE hybrid 80K

[CarelHassink]

I did not post for some time,
Meanwhile we have developed our GRNbms, dedicated to work with VAG group MEB battery modules
with this baby I supercharge my electric car.... well not really super super but 50kW is OK for me
We're located in Europe, Netherlands, during this autumn/winter season not so much sun,
but we manage to stay off-grid.

If people need advice how to set-up such a system let me know in comment

NICE! Do you fill the battery bank with solar? and then do a 50kwh charge in a few hours? or how are you operating the system.

Thank you for sharing

Oops obvious do not visit this forum often.. my bad..

The photos show the set-up in my warehouse.
on the roof is a 40kWp solar array
We use a DEYE 80kW Hybrid HV inverter, connected to the battery bank, controlled by our GRNhv-boxes,
to power the whole warehouse parallel to the grid
a Loxone server runs as EMS ( https://loxone.com ) controlling all energy streams

Grid connection is a meager 25A 3 phase. the lowest possible grid connect one can get form the service provider in the Netherlands for a commercial building.

We buffer via the 350kW battery bank to run our appliances.
show case is the use of a 50kW CCS charger,
Charging a 60kW BYD battery usually takes 1 hour to 1 hour 20min depending on SOC%

We produce a bms system, GRNbms, dedicated to be used with VAG battery as found in many cars brand from the group like VW ID.series, Audi, Skoda Seat Cupra, and adopted in partnership with Ford Europe in their e-Explorer SUV

We also bulk sell B2B these VAG MEB batteries.
