A good example is the cable sizing calculator, that doesn’t correlate with the information supplied in the Victron manuals with the products. ### 1/5 — Sprachen *2025-06-01* Leider nicht in Deutsch. ### 3/5 — Langue française *2025-02-01* Dommage que la traduction ne soit pas disponible ### 1/5 — Pas en Français !!! *2025-01-28* Aucune traduction en français et pourtant on est en France avec certaines obligations !!! Donc inutile vaut mieux utiliser Google pour les renseignement. ### 4/5 — Helpful reference, but… *2024-11-21* I find this app to be a helpful quick reference, but when in North America and Caribbean, getting wire sizes shown in mm2 is not very helpful. I end up using for go online to convert to AWG size. Developers, please consider providing both, or having a setting to select which is shown. Thanks! ### 5/5 — So Easy *2024-10-22* Extremely easy to use it’s also 100% free ### 3/5 — Usability *2024-07-21* The range input is very inaccurate and it’s difficult to set correct value. Please add ability to set it manually on double click or use iOS scroll feature. Also review to add to the app the functionality of “MPPT sizing calculator” as well. ### 4/5 — Nett aber könnte ein Update vertragen *2024-03-19* Tooles Tool zum kalkulieren von Kabelquerschnitten. Aber leider nicht detailliert genug. Es wäre besser, wenn man den Strom zwischen 10-100A etwas granularer in 10A einstellen könnte. Zwischen 50A und 100A gibt es garkeinen Zwischenwert. Außerdem wäre es sinnvoll, wenn man eine rote Warnung erhalten würde, wenn der gewählte Querschnitt zu klein ist, z.B. Spannungsabfall größer 2,5% oder so. Vielleicht wäre eine Bewertung des Kabels mit einem Ampel System (grün/gelb/rot) hilfreich ### 2/5 — Not for the imperial market *2024-02-13* A pretty nice app with informative features… Only gave two stars because everything is based on metric measurements with no way to convert to imperial for the us market. ### 3/5 — Nicht schlecht, aber … *2024-01-14* Die App ist nicht schlecht. Hilft um paar kleine Grundlagen wie Kabelquerschnitt und so zu berechnen. Auch die LED Analyse ist gut. Aber, einen Stern Abzug weil nicht das ganze auch auf Deutsch, und einen Stern Abzug weil man nicht weiß ob das nun positive oder negative ist für das Gerät/Batterie bei den LED Beschreibungen. ## Frequently asked questions about Victron Toolkit ### What is Victron Toolkit used for?
