Despite my best efforts the engineers at the installation company had missed the fact there are 4 distribution boards (consumer units) in total and the installer was concerned about not having 32A of headroom from the 80A supply so the EVSE has initially been capped at 16A.<\/p>\n<p>The installation company is going to send me an OWL monitor so they can check how much of the 80A I&#8217;m normally using.\u00a0My own monitoring shows there&#8217;s never less than 40A spare so that should be a formality. Once they&#8217;re happy, the EVSE will be remotely re-configured to supply up to 32A as originally intended.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>As reported previously, my application to join the Electric Nation research trial was accepted a few weeks ago.
