<div class="fr-view clearfix"><p>You need to think about the Power. Power is the product of Volts and Amps.<br />Also the resistance of the cable between the MultiPlus and the distribution board is reasonably constant. The Voltage drop over this cable will depend upon how much current is flowing through it.</p><p>So let's choose a constant current of 10A (2.3KW) and continue to assume that the Voltage at the distribution board is 230V. If the Voltage at the MultiPlus terminals is 225V when charging with 10A mains, then the resistance of the cabling is (230-225) / 10 = 0.5Ω.</p><p>Now with a constant cable resistance or 0.5Ω we can then calculate the Voltage at the terminals at any point in time for a given current and distribution board Voltage.<br />If MultiPlus is back-feeding 10A (2.3KW) into the distribution board then 0.5 x 10 = 5. MultiPlus needs to raise its Voltage by 5V to get 10A to flow, so the Voltage at its terminals will need to be 235V. With 5A, the Voltage would be 232.5V.</p><p>These calculations are very basic, backfeeding will cause the distribution board Voltage to increase also as there is more cable between it and the local substation.<br />Also the grid Voltage is constantly changing so those calculations are merely for a snapshot in time.</p></div>Mon, 20 Jul 2020 17:45:13 GMTWKirby
