To complete the Kt pulse setup of the energy meter, please goto section 4.12.1.7.3 under DI setting.
IMPORTANT: For installations that do not have such meter installed, or do not have pulses
available, it is necessary to goto the software setup to link the total energy kWh data to the
inverter energy data, instead of a real meter. For this procedure, please goto section
4.12.6.1.
