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: ![IMG_0195](https://europe1.discourse-cdn.com/victron/original/3X/9/1/913d4dae6b6922bc7153ac151fbdcc3518e663e2.jpeg) > **[FSP-200M - Jinhua Dokio Technology Co.,Ltd](http://www.dokiosolar.com/wap/product/show-3.html)** 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. > **[MPPT Calculator - Victron Energy](https://www.victronenergy.com/mppt-calculator)** > > MPPT Calculator - Victron Energy 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](https://www.victronenergy.com/media/pg/Manual_SmartSolar_MPPT_75-10_up_to_100-20/en/installation.html#UUID-a02f8083-769b-b3b4-ab21-3c40c5814854) ![Mppt 5 volt](https://europe1.discourse-cdn.com/victron/original/3X/b/e/be8b9961e1a5deac9c8548985105a74b8ecdf814.png) 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
