  • Page 4: Safety / Warnings

    Read and follow all instructions carefully!! This chapter contains safety instructions that must be followed when installing, operating and servicing the ZENER ECODRIVE 8000. Non-compliance may result in damage to the ECODRIVE, the motor or other equipment being driven. Non-compliance may also result in physical injury or death to personnel, livestock or wildlife.
  • Page 5 ZENER ECODRIVE® 8000 ZENER VARIDRIVE SOLUTIONS Do not touch the terminals of the equipment or any associated motor wiring when the equipment is energised, even if motor is stopped. Electric shock may result. In Auxiliary Power (Dual) Supply applications where the ECODRIVE is supplied from AC power, the photovoltaic conductors must be treated as being live parts.
  • Page 6 ZENER ECODRIVE® 8000 ZENER VARIDRIVE SOLUTIONS The ECODRIVE does not have integral disconnect devices and these must be provided externally for each supply source. The disconnector in the DC supply circuit must be rated to switch the whole photovoltaic array current and rated to switch the array maximum open circuit DC voltage at the expected minimum temperature.
  • Page 7 Ensure you understand how to operate the equipment before attempting to run the motor/pump to test direction. Use the set-up guide provided to setup / commission the equipment or consult Zener for assistance. If you are require clarification or more information on any of the above please contact Zener.

    It prevents current flow from the ECODRIVE to the PV modules. ECODRIVE This is a ZENER product that converts a DC supply (and AUX AC supply) to control a 3phase induction motor dependent upon the power extracted from an array of solar panels. A registered trademark of Zener Electric Pty Ltd.

  • Page 9: Introduction

    There are many modes of operation that can be customised depending on your individual requirements. To simplify installation & setup, Zener has selected 2 common modes of operation in which an ‘Application Menu’ has been developed for each. These are further detailed within this manual.

  • Page 10: Standard Applications

    ZENER ECODRIVE® 8000 ZENER VARIDRIVE SOLUTIONS STANDARD APPLICATIONS Application – Tank Fill The ECODRIVE is configured to pump and fill a tank or vessel when the level is not full and there is sufficient solar energy available. An AC supply can also be used to pump when insufficient solar available.

  • Page 11: Pressure Control

    ZENER ECODRIVE® 8000 ZENER VARIDRIVE SOLUTIONS Application – Constant Pressure Control The ECODRIVE is configured to provide a constant pressure using an integral PID controller. The ECODRIVE monitors the pressure and adjusts the motor/pump speed to achieve the set pressure.

  • Page 12: Technical Specifications & Ratings

    Refer to instruction manual IM00124 for more details on ratings, in particular for standard 3phase AC operation and recommended circuit protection. For single phase operation a DC bus choke must be fitted and a derating applied. Contact Zener for assistance. The output voltage cannot be higher than the AC input voltage or 70% of the DC input.

With standalone solar installations, blocking diodes are optional but recommended with multi-string installations to ensure maximum efficiency where partial shading of the PV modules may occur.

  • Page 14: Solar Array & Pv Selection

    ZENER ECODRIVE® 8000 ZENER VARIDRIVE SOLUTIONS THE SOLAR ARRAY & PV SELECTION: The Solar Array consists of a number of Photovoltaic (PV) modules connected in a series & parallel combination to achieve a certain voltage, current and power. It is important to select these carefully as the PV modules are a major cost of an installation and can be very expensive to rectify.
