Goodwe GW5048D-ES, GW3648D-ES, ES Series Manual

Introduction

GoodWe ES series inverters (hybrid) are bidirectional which apply to PV system with battery to store energy.
Energy produced by the PV system is used to optimize self-consumption; excess energy is used to charge the batteries, and then fed into the public grid when the PV energy is adequate,
When PV energy output is insufficient to support connected loads, the system automatically get energy from the batteries if battery capacity is abundant. If the battery capacity is insufficient to meet own consumption requirements, electricity will be drawn from the public grid.
GoodWe ES series inverter is design for both indoor and outdoor use.
See fig. 1-1 for example of Basic hybrid PV system

Work Modes

ES series inverters have the following main work modes based on different conditions:

Mode1: Energy produced by the PV system is preferred for local load. And the excess energy is first used for charging batteries, then feeding to the grid.
Mode2: If there is no PV, battery energy is used for local load first, the grid also can supply when the battery capacity is not enough.
Mode3: If the grid is fault or there is no grid, the system can still work, PV and batteries supply energy for local load.
Mode4: The battery can be charged by the grid, time and power of battery charging can be set up flexibly.
