[QUOTE="pedg, post: 500484, member: 33044"] In Cambridge so UK power network the DNO. Tried a number of sparks but most end up at the 'We will get back to you" stage that never happens and with various things a bit up in the air I have not got round to rehassling any of them but will try again. You can charge the battery from mains as well as from the solar. Obviously only really of use if on a variable tariff. Intending to move to octopus agile tariff so on the rare times they pay you to use electricity could well be wanting to put 16A into the battery and 32A into the EV at the same time. Basically I think my question best asked as 3 separate questions: 1) How much of the wiring would need to be upgraded to 25mm for the DNO to be happy given I don't have wires going directly from the meter to consumer unit? Given max current from each branch from the final junction box would be under 60A individually assume 25mm through to that junction box should be fine? 2) Can I get a spark in to do the upgrades from the meter onwards before the other changes? (supply company promise to attend at the same time as the DNO to do their bit). 3) What should I have the 80A RCCB replaced with? [/QUOTE]
