Inverter-based resource
An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation (CIG), include the variable renewable energy generators (wind, solar) and battery storage power stations. [1] These devices lack the intrinsic

Understanding inverter startup voltage. | DIY Solar Power Forum
Meaning that each individual string has to be of a certain size to reach the inverter start up voltage separately. For example; inverter start up voltage 90v. So each string has to be above this voltage separately or does the whole array work to achieve this startup voltage independent of the amount of strings?

How does a solar / PV inverter get preference over grid source for
Only when the grid voltage exceeds some sane limit, will the solar inverter stop production. So if you draw a circuit of a solar inverter, a load and an AC source/sink, you will see that the current going to the load is sum of two currents: the current from solar inverter, and the current from the AC source/sink: I_load = I_sourcesink + I_solar
Current Source Inverter
In terms of the types of DC sources, the DC–AC inverters can be classified into voltage-source inverters and current-source inverters. It is noticed that voltage-source inverters possess freewheeling diodes that provide pathways of reactive power from the load to the supply when the current and voltage across the RL load have opposite polarity.
Fault Current of PV Inverters Under Grid-Connected Operation: A
The fault current from a PV system also depends strictly on the PV inverter control. Current control mode (CCM) and voltage control mode (VCM) refer to the main two control schemes employed in practice (Wang et al.
