 In multiphase installations with batteries, in countries with phase-balancing grid meters, the battery will export to the grid on one phase the amount it lacks on another phase, as if it is using the grid as a 'transport' between phases. Since the grid meter will balance the amount in and exported on the two phases, the net result is zero. The Envoy multiphase consumption CTs, however, will report the amounts on both phases, resulting in too high export on one and too high import on the other. One needs to use the sum of grid import and export to eliminate this effect.
