This manual contains important safety instructions that must be followed during installation and maintenance of the system. Scope  This manual describes the assembly, installation, electrical connection, commissioning, maintenance and troubleshooting of the ZCS 3000SP storage inverter.

  • Page 7: Introduction

    1. Introduction The 3000SP storage inverter is an AC-connected bidirectional electrical energy inverter developed for photovoltaic production and domestic storage systems. The system can be combined with WeCo or Pylontech batteries offered in kit form by ZCS Azzurro. The system is also compatible with all existing photovoltaic inverters and modules and can be integrated into an existing system or installed together with a new photovoltaic system.

  • Page 8: Preliminary Safety Instructions

    For safety reasons, this inverter can only be installed by a qualified electrician with the necessary training and/or skills and knowledge. Zucchetti Centro Sistemi S.p.A. declines all responsibility for damage to property or personal injury caused by incorrect use of the device.

  • Page 9: General Safety Instructions

    If necessary, request assistance from an installer of photovoltaic systems or from Zucchetti Centro Sistemi SpA. Transport of the equipment, especially by road, must be carried out with vehicles suitable to protect the components (in particular, electronic components) against violent knocks, humidity, vibrations, etc.

    7. Connections in three-phase mode The 3000SP storage inverter is a single-phase inverter, but it can be installed on a three-phase system by feeding and withdrawing power on a single-phase, with the aim of zeroing the vector sum of the powers of each phase ready by the import/export meter.
  • Page 65 According to this logic, the energy vector exchanges with the grid are cancelled and the 9 kW requested by the utility are met in part by the photovoltaic production and in part by the batteries. This configuration can be used when the installer deems it appropriate that the system manages the energy storage according to a global logic of a three-phase system, which takes into account the production and consumption on all phases.
