Page 2: Purpose
MPPT inverters for residential solarZero and solarClassic systems. SCOPE This document applies to single-phase installations with Zeversolar string inverters and covers the mechanical and electrical part of the inverter installation instruction. The focus of this SOP lies on the physical installation of Zeverlution 2000s and Zeverlution 4000 inverters and any associated switch gear, DC and AC wiring. -
Page 3: Installation Procedure
STANDARD OPERATING PROCEDURE String Inverter Installation – Zeverlution Series Version 1.2 Effective date 02/08/2017 INSTALLATION PROCEDURE String Design Guidelines To ensure efficient operation and compliance with the regulations, string design options are limited. As per AS/NZS 5033 section 2.1.6, PV modules that are in the same string must have the same tilt and azimuth angle within a tolerance of ±5°. -
Page 4: Maximum String Voltage
STANDARD OPERATING PROCEDURE String Inverter Installation – Zeverlution Series Version 1.2 Effective date 02/08/2017 5.1.4 Maximum String Voltage The maximum length of a single string is dictated by the string voltage, taking temperature coefficients and the local ambient temperatures into account. For all solarcity installation zones, the maximum number of panels in a single string of 60-cell modules with a rated output at STC of less than or equal to 300 Watts, is ten (10). -

STANDARD OPERATING PROCEDURE String Inverter Installation – Zeverlution Series Version 1.2 Effective date 02/08/2017 Clearances Heat must be able to dissipate from the inverter through the heatsink on the back. It is important to consider the recommended clearances. The below table is for a single inverter only. - Page 7 STANDARD OPERATING PROCEDURE String Inverter Installation – Zeverlution Series Version 1.2 Effective date 02/08/2017 Any DC cabling must be adequately mechanically protected and must be run in HD Solar conduit. Where it is exposed to direct sunlight, HD conduit, marked with the letter T, is to be used. For any internal cable runs (e.g.
- Page 8 STANDARD OPERATING PROCEDURE String Inverter Installation – Zeverlution Series Version 1.2 Effective date 02/08/2017 SUNCLIX Connectors The inverter uses SMA’s SUNCLIX to connect the DC string to the inverter. One (Zeverlution 2000s), or two pairs (Zeverlution 4000) respectively, are shipped with the inverter. It is important to assemble the connectors correctly.
