Technical FAQs 3

What is the maximum voltage rise for an inverter?

The maximum voltage rise for a system must be 4.6V (2%). For example, the local grid may be functioning at 252V, and your inverter is exporting 4V back into the grid pushing it over the grid standard. In 2016, significant changes to AS 4777.2 occurred and a 255V output was set on inverters.

Can a parallel inverter be used on one MPPT?

MPPT Current A - Generally, only inverters with an MPPT current rating of 18A or higher, and an Isc rating greater than 20A, can be used with parallel strings on one MPPT (Depending on the current rating of the panels used) - Always refer to manufacturers guidelines and specifications.

What inverters are coming out in 2023?

The latest inverters added to the list in 2023 are the next-generation inverters from Sungrow, Fronius, Goodwe, Growatt, Solax and Sofar, plus the new DS3D and QT2 microinverters from APsystems, along with microinverters from ZJ-Beny and Envertech.
