Subida de Voltaje

Pregunta. . . Qué es subida (caída) de voltaje? • Al diseñar circuitos eléctricos, comúnmente calculamos la caída de voltaje (Vdrop) para mantener la calidad de voltaje y reducir la pérdida de energía en los cables. • Como los sistemas fotovoltaicos de inversor interconectado a la red son generadores de corriente que toman su referencia de voltaje del punto de conexión, el voltaje tiende a subir en el generador según la corriente viaja hacia el punto de conexión. Por esta razón este adiestramiento tratará el tema de la Subida de Voltaje (Vrise). 15 | © 2017 Enphase Energy, Inc. Learning and Development |

Entendiendo la Subida de Voltaje (Vrise) La resistencia de los cables hará que el voltaje en el micro aumente cuando la corriente viaja hacia el punto de conexión. Vrise Alimentador Agregador Q Cable Q Vrise <= 2% 16 | © 2017 Enphase Energy, Inc. Learning and Development |

Learning Check Is it ok to install a 15 A breaker instead of a 20 A breaker? a) No, nunca b) Yes, but you will have to limit the number of micros per circuit c) Yes but the conductors from the micros to main panel have to be sized down to match the 15 Amp limit d) Yes, when the Q Cable supports a larger 10 AWG wire 50 | © 2017 Enphase Energy, Inc.
