Hi everyone,
We have installed a great system with a Pylontech battery and 3x a Multiplus II. The system is running on DESS.
The customer has a KIA EV3 with a V2L function (3.6 kW).
Now they would like to do the following: charge the Pylontech battery via V2L using a charger.
What’s the best way to approach this?
And do you have any tips?
Kind regards,
Bart van Middendorp
Easiest would be another multiplus, or a skylla charger
I have also 3 phase multiplus II 5000VA system.
I’m using separate MeanWell AC/DC 3kw power supply connected to Lynx Distributor.
MeanWell let you limit output amps so I have set it to 58A, thats about 3,4kw in AC end by the car.
An I have also set output voltage to 54V so it wount overcharge my battery.
Hello Bart,
That’s a nice setup and interesting concept which I’m going to adopt. Have an off-grid project in which we are currently wiring up a very similar setup, 3 phase 30kva MPII cluster with 60kwh of Pylontech US5000s. The client also has a Kia with V2L and is seeking to be able to charge the system from the EV if needed as a backup source.
Wondering if you have got a good result and worked out any controls that are needed?
Reading other posts wondering if an isolation transformer is needed inbetween the V2L socket and the MP II with the V2L being a floating ‘protected supply’ to prevent grounding issues?
We are installing a separate MPII 5kva GX, set to be used as a charger only, and to prevent overloading the EVs 3.6kw Output, planning on setting the Multiplus charge rate somewhere below 3kw maybee 50Amps.
Have chosen the MPII GX for dedicated charger with intention of having the BMS CANbus connected to it and also the Cerbo on the 3-phase setup to try and have the activate DVCC management on both somehow.
Maybee considering using a relay on the Cerbo GX and remote on off on the separate MPII charger so it will only be enabled or allowed when BMS SOC is below a level e.g 80% to prevent issues of potential overcurrent above the CCL limits.
Will share any further ideas and some photos once setup.
Thanks for sharing
