FAQS 4

What are the requirements for a IPSD inverter?

Inverters used with IPSDs must be tested to AS/NZS 4777.2. Systems over 30 kVA require interface protection. Must island in under 2 seconds upon loss of grid connection. Signage and protective measures (like securing current transformers, system schematics) required at the main switchboard.

Can a multiple mode inverter disconnect a grid-interactive port?

(e) The connection or reconnection time and behaviour shall conform to Clause 4.7. (g) Where the device under test is a multiple mode inverter meeting the performance classification for output requirements of AS IEC 62040.3, it may disconnect the grid-interactive port during this step.

What is an inverter energy system?

Inverter energy systems are often comprised of multiple inverters used in combination to provide the desired inverter energy system capacity or to ensure that voltage balance is maintained in multiple-phase connections to the grid.

Can a PV inverter be disconnected from a grid?

Some properties of a PV inverter grid connection can cause the grid voltage at the inverter to increase and exceed the permissible operating range if the feed power is high. If this occurs, SMA grid guard, an independent disconnection device integrated into the inverter, will safely disconnect the inverter from the grid.
