  • Page 3: Introduction

    01 INTRODUCTION ETC series bidirectional inverter is designed for indoor use, which could be used with or without existing PV system to store energy using batteries. Energy produced from the PV system will be used to optimize self-consumption, excess will be used to charge the battery, anymore could be exported to the grid.

  • Page 4: Safety & Warning

    1.2 Safety & Warning The ETC series inverter strictly complies with related safety rules for product design and testing. Please read and follow all the instructions and cautions on the inverter or user manual during installation, operation or maintenance, as any improper operation might cause personal or property damage.
  • Page 5 Safety warning Any installation and operation on inverter must be performed by qualified electricians, in compliance with standards, wiring rules or requirements of local grid authorities or companies (like AS 4777 and AS/NZS 3000 in Australia). 1. Prohibit inserting and pulling the AC and DC terminals when the inverter is running. 2. Before any wiring connection or electrical operation on inverter, all DC and AC power must be disconnected from inverter for at least 5 minutes to make sure inverter is totally isolated to avoid electric shock.
