Since AS5033:2014 starts to implement in Australia, the clause 18.104.22.168 in this standard
gives inverter suppliers an opportunity to integrate a built in DC load break disconnector
on the inverter. By this way, additional load break disconnectors adjacent to inverters are
not requested in installations.
The standard of AS5033:2014 and AS4777.2:2020 (draft version) both clearly list the
requirements on the built in DC switch disconnectors such as shall be DC PV2 and
compliant with IEC60927.3 etc.
GoodWe embraces this new standard change and believes this change could obviously
decrease the safety hazards in solar systems such as the external breaker which is one
of main possible causes of serious damage to the entire solar system. To better fit the
new standard and reduce the installation time and cost, GoodWe gradually integrated the
compliant DC load break disconnectors to inverters. Currently GoodWe inverter models
XS, DNS, MS, SMT and EH are available with compliant DC switch disconnectors. All
customers can contact with GoodWeâ€™s authorised local wholesalers or GoodWe Australia
directly for collecting the GoodWe load break disconnector manufacturer declaration.
Additional to the built in DC load disconnector on the GoodWe SMT series, we now offer
a DC cover as part of the standard package as default. GoodWe believes the built-in DC
disconnector plus DC cover ensures the installation is neater and safer. Furthermore,
with just 40kg weight and compact design, the SMT series is easier to handle and install.
Featuring a maximum DC input voltage of 1100 V, wider MPPT range, and a start-up
voltage of 180 V, the SMT series guarantees an earlier power generation and a longer
operating time in order to maximize ROI to system's owners.
