Once installed, switching is expensive. Four questions to help you decide.  <\/p>\n<h2>Question 1: single-phase or three-phase connection?<\/h2>\n<p>If you have a single-phase connection (most older homes), then 11 kW three-phase is not an option anyway without adjustments to your meter cupboard. In that case: 7.4 kW single-phase is your maximum, and that is more than sufficient for 95% of users. <\/p>\n<h2>Question 2: how much do you drive per day?<\/h2>\n<p>Under 100 km\/day: 7.4 kW or 11 kW is more than enough \u2014 a night of charging adds 60\u2013110 km. Above 200 km\/day or multiple vehicles on one station: then 22 kW is worth the extra cost. <\/p>\n<h2>Question 3: do you have solar panels?<\/h2>\n<p>If you have PV and want to charge your vehicle during the day using solar energy, you need a station that can modulate with solar surplus. Not every 11 kW station can do this. Specific models (Smappee, Alfen Eve Single Pro-line with the correct configuration, Enovates with PV add-on) can.  <\/p>\n<h2>Question 4: do you want split billing with your employer?<\/h2>\n<p>If so: your station must be OCPP-compliant and capable of being linked to your employer&#8217;s management platform. Inexpensive stations from DIY stores often do not meet these requirements. Ask explicitly before purchasing.  <\/p>\n<h2>The decision tree in one sentence<\/h2>\n<ul>\n<li>City dweller with single-phase and average driving habits \u2192 7.4 kW simple station, approx. \u20ac1,500 installed.<\/li>\n<li>Standard family with PV and EV company car \u2192 11 kW smart station with solar integration, approx. \u20ac2,000\u2013\u20ac2,500 installed.<\/li>\n<li>Frequent driver, two vehicles, or operational needs \u2192 22 kW smart station, approx. \u20ac2,800\u2013\u20ac3,500 installed.<\/li>\n<\/ul>\n<h2>What is NOT the right reason to choose 22 kW<\/h2>\n<p>&#8220;Just to be safe&#8221; or &#8220;because it&#8217;s possible&#8221; \u2014 if you are never going to notice the difference in charging time, it is a wasted budget. 11 kW simply fully charges a vehicle overnight. 22 kW does the same, but 5 hours faster \u2014 and that doesn&#8217;t matter if you&#8217;re sleeping until morning anyway. <\/p>\n<h2>Don&#8217;t forget<\/h2>\n<ul>\n<li>The installation cost (cabling, grounding measurement, potentially upgrading the circuit group) can be higher than the station itself. Always ask for a total price. <\/li>\n<li>Smart stations require a Wi-Fi or 4G connection at the installation site \u2014 check this in advance.<\/li>\n<\/ul>\n<h2>Read also<\/h2>\n<ul class=\"lees-ook\">\n<li><a href=\"https:\/\/certipower.be\/kennisbank\/smappee-alfen-of-enovates-kiezen-in-welke-situatie-kies-je-welk-merk\/\">Choosing Smappee, Alfen, or Enovates: in which situation do you choose which brand?<\/a><\/li>\n<li><a href=\"https:\/\/certipower.be\/kennisbank\/capaciteitstarief-en-slim-laden\/\">Capacity tariff and smart charging<\/a><\/li>\n<li><a href=\"https:\/\/certipower.be\/kennisbank\/load-balancing-wat-en-waarom\/\">Load balancing: what and why?<\/a><\/li>\n<\/ul>\n<div class=\"cta-block\">\n<p><strong>Want to know which station fits your situation?<\/strong> View our packages for individuals with indicative prices, or <a href=\"https:\/\/certipower.be\/en\/schedule-a-call\/\">request a personalized quote<\/a>.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Which home charging station suits you? 11 kW, 22 kW, or smart charging \u2014 a simple decision tree. <\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"slim_seo":{"title":"Choosing a home charging station: 11 kW vs 22 kW vs smart station \u2014 decision tree - Certipower","description":"Which home charging station suits you? 11 kW, 22 kW, or smart charging \u2014 a simple decision tree."}},"kennisbank_categorie":[45],"class_list":["post-2016","kennisbank","type-kennisbank","status-publish","hentry","kennisbank_categorie-products"],"acf":[],"_links":{"self":[{"href":"https:\/\/certipower.be\/en\/wp-json\/wp\/v2\/kennisbank\/2016","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/certipower.be\/en\/wp-json\/wp\/v2\/kennisbank"}],"about":[{"href":"https:\/\/certipower.be\/en\/wp-json\/wp\/v2\/types\/kennisbank"}],"wp:attachment":[{"href":"https:\/\/certipower.be\/en\/wp-json\/wp\/v2\/media?parent=2016"}],"wp:term":[{"taxonomy":"kennisbank_categorie","embeddable":true,"href":"https:\/\/certipower.be\/en\/wp-json\/wp\/v2\/kennisbank_categorie?post=2016"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
