Which Victron charge controller for Dokio 200W suitcase

Q&A and troubleshooting

Dear all,

Would like some help choosing the right charge controller.

We have ordered a 200w solar suitcase from DOKIO.
The FSP-200M

It comes with its own (cheap) charging controller but I would love to replace it with an higher end smart Victron MPPT one

The panel specs on DOKIO site state:

If I put the panel specs in the victron MPPT sizing calculator , it doesn’t give any result.
It goes wrong when I put the the Vmpp Value of 18v given by DOKIO it won’t suggests any.

I would like to buy the Victron Energy SmartSolar MPPT 100V 20a

Is this compatible or not?

Thanks a lot

Victron recommends solar panels with 36 cell to ensure that the PV voltage exceeds the battery voltage by 5 volts. PV array install
Mppt 5 volt

The 75-15, or the 100-20 would be suitable.
Just be aware that due to the low PV voltage / high battery voltage, the mppt might not always strat charging the battery.

Thanks a bunch, that explains a lot.

Do you think it’s still worthy portable combination or should we try to find another solar suitcase?
This one had good reviews and price-quality/durability was excellent.

We want to use this setup:
1 suitcase panel 200w (below 200€)
victron 100/20 controller
Victron 800/12 inverter
And 100ah lifepo4 12 v
