4.8 PV string considerations
There are a large number of PV module string combinations that will offer optimal performance
from either the M3-TL-AU, M4-TL-AU and M5-TL-AU inverters thanks to its wide full
power MPP range (50 V – 48

INFORMATIONS!
Follow the temperature multiplication factors given in AS/NZS 5033
table and the PV module manufacturer specified V/Temp coeffici-
ent to ensure PV string voltage is less than < 600 Vdc. Maximum
inverter PV input voltage for all possible weather conditions in the
location of installation.
System wiring voltage losses should be no greater than 1 to 2
percent for optimal system efficiency and performance.
4.9 Inverter connections
4.9.1 General information
Installation and commissioning must be performed by a licensed
electrician in accordance with local, state, and AS/NZS 3000
requirements.
Inputs and output circuits of this unit are isolated from the enclo-
