As part of their information disclosure regulations, Transpower and all 29 EDBs are required to report the duration, frequency, and causes of power outages. The duration and frequency of outages are normally expressed in (system average interruption duration index) and (system average interruption frequency index). In the five years to 31 March 2024, the 29 EDBs reported an average unplanned-outage SAIDI of 204.04 minutes and a SAIFI of 1.87, and an average planned-outage SAIDI of 101.16.

What are PV string DC combiner boxes?
PV String DC combiner boxes are key components in PV solar power systems, which are placed between solar modules and the inverter. Available in the following variations:
What is a PV combiner box?
In every photovoltaic (PV) system, stable power generation relies on more than panels and inverters. Hidden behind the scenes is a critical piece of equipment: the PV combiner box. Though easy to overlook, this device plays a decisive role in current collection, circuit safety, surge protection, and intelligent monitoring.
How many PV string inputs can a combiner box support?
A standard combiner box supports 6–24 PV string inputs, with typical current per string ranging from 10–20A. Key features include: Reverse current protection is essential when module shading or mismatched strings cause imbalance. 2. Multiple Layers of Electrical Safety Protection These protection layers significantly reduce system downtime. 3.
What is a combiner box?
In off-grid applications, combiner boxes are crucial for consolidating multiple solar panel outputs into a single DC output that feeds into battery storage systems or DC loads. For example, in remote areas where grid access is limited, an off-grid solar system can utilize a combiner box to manage inputs from various panels efficiently.

New Zealand is a net importer of energy but has a high degree of energy independence with a self-sufficiency index of 73% in 2023. While it exports coal, gas (in the form of methanol) and oil, electricity and biomass supply is indigenous and refined petroleum products are imported. But that advantage is now under pressure. The ratio of non-renewable and renewable energy sources was fairly consistent from 1975 to 2008, with about 70 per cent of primary energy supply coming. . With diverse renewable energy options, our country is well-positioned to transition to a sustainable, low-emissions energy system.
