Vector Powersmart

passionate about renewable energy

At PowerSmart we believe in a future driven by renewable energy and have been leading the charge since 2007. We offer bespoke renewable energy solutions including solar power and battery solutions for utility, commercial and business applications. From experience, we know that no two organisations or communities energy consumption or energy problems are the same. As a result, PowerSmart designs, engineers and installs bespoke solar power and battery storage solutions while offering financial and maintenance packages.

Why PowerSmart?


We make it easy, by taking care of every aspect of your renewable energy project. We have ensured we have very thorough systems and processes in place, such as our Health, Safety and Environment procedures to ensure every project is delivered on time and performs as expected.

Two of our founding directors are engineers and so since 2007 when PowerSmart started we have designed and built systems to last and be proud of. As a result we have won over 20 awards including 5 SEANZ awards in 2014 and 2 SEANZ awards in 2015. including Largest Grid Tied Implementation for Sylvia Park and Best Best Solar PV System with Storage for Tuvalu and Northern Cooks Project.

PowerSmart Solar - Eric Murray's Testimonial

In this short video one of New Zealand's most successful rowers. Eric Murray, talks about his family's decision to have solar installed on their dream home in the St Kilda development near Cambridge.

Revolve Energy and Vector Powersmart for Camp Glenorchy

Opened in March 2018, Camp Glenorchy has been designed, built and operated in line with the philosophy and principles of the living building challenge (LBC), recognised as the most stringent environmental design certification in the world. For the first half of 2019 Camp Glenorchy generated twice its energy use and used half the energy per guest as a similar facility.

Glenorchy is a very isolated area, 45km of single electricity line in overhead in an alpine environment supply the town. Consequently the site experiences regular power outages and power quality issues. Camp Glenorchy is a significant site within the community and has been designed as a Civil defence hub to assist the community to manage major natural disasters such as earthquakes, flooding and storms.

In the pursuit of continued improvement 2019 was monumental as Camp Glenorchy made a number of significant improvements including the addition of 130kVA, 232kWh Qinous lithium battery system (BESS) and an energy management system (EMS) These recent additions round out the solution into a completed integrated site that achieves exemplary levels of energy efficiency, comfort and innovation. In addition the site now has the ability to interact in a meaningful way with the local grid.

Key innovations:

  1. Micro grid, 2 adjacent sites (Camp Glenorchy and Mrs Woollys) with 15 building and a campsite operating behind a single meter. The structural allows shared use of onsite generation and energy storage.
  2. The microgrid controller achieves a high level of PV self use increasing return on investment to the property through load shifting and ensures backup of the site for extended outages, utilising the lowest cost energy source and balancing power flows.
  3. The EMS receives control period demand signals from Auroa and sets the operating limits of grid import to ensure no demand charges are incurred by site.
    1. Provides a user interface to allow staff to respond to Transpower demand events in order to receive payment for grid support at critical times.
    2. Actively monitors the battery SOC in off grid mode and hierarchically sheds load to avoid where possible use of the generator.
  4. An interface is provided to allow staff to override automatic settings to suit operational requirements.
    1. Extensive energy monitoring of over 250 electrical sub circuits for, with a live dashboard for optimisation and energy management.
    2. Extensive building controls make significant contribution to achieving the 50% reduction in energy use when compared to other similar facilities. The completely integrated solution controls all key systems including ground source heat pumps, solar water heating, space heating, lighting, ventilation, showers, irrigation. The system is also integrated with the site booking system ensuring that the rooms are only heated when a check-in is imminent, reducing standing losses.

Vector Powersmart for the Niue Renewable Energy Project

Vector Powersmart (formerly known as PowerSmart) has completed many projects in the South Pacific since 2012, however none of these projects have involved the level of difficulty of this project with the need to integrate existing and new renewable energy infrastructure while working on a live network. This brought a number of challenges, but the result is that now 28.6% of Niue’s energy needs (measured since May 2019) are being met by renewable generation, saving approximately 130,000L of diesel‚ setting Niue up well to achieve its goal of 80% renewable energy by 2025.

What was done?

There were four parts of the project;

  1. Working on the existing solar plants to establish communication with the Niue Central Power Station.
  2. Installing 600kW of solar to increase the islands overall solar capacity to 1.1MW of solar generation. The solar array was installed well inland on high ground to avoid any potential damage from cyclones in the future.
  3. Installing 0.80MW / 3.15MWh Tesla Powerpack 2 (BESS) at the Niue Power Station to maximise the use of solar on the island and eliminate the need to curtail solar to maintain grid stability.
  4. Installing Vector PowerSmarts bespoke Energy Management System (EMS) to manage Niue’s electricity grid by balancing the new and existing solar generation, existing diesel generators and BESS. To meet the demands of the Niue electricity grid Vector Powersmarts EMS:
    1. Controls when diesel generators need to be turned on or off
    2. Assesses what electricity is being produced by the solar and when to use this directly to power the demands of the grid or when to send it to the BESS
    3. Assesses how much electricity is stored in the batteries and what actions need to be taken, and turn diesel generators on or off

Essentially it is the central brain talking with the original diesel generators, original and new solar arrays and the BESS to manage Niue’s electricity network. All of this had to be done while working on a live network.


Through the addition of an EMS, BESS and more solar to the network Niue can often operate without any diesel generators running for up to 10 hours at a time - on average the generators are switched off for 5-7 hours per day. Over the last 5 months the total integrated system has resulted in 28.6% of Niue’s electricity coming from solar renewable sources, saving over 130,000 litres of diesel.

Powersmart Solar - Vunabaka Resort Fiji

Vunabaka resort is typical of many of the projects that we work on, in that years worth of work have gone into it before anything seems to happen. This is a project that is at the cutting edge of solar PV projects and uses the best technology sourced from all over the globe. 

In 2012 we were approached by some developers who wanted to build a beautiful resort in Fiji, but like many Pacific islands there was the major issue of electricity. Their solution at that stage was to do multiple off grid homes and lodgings all with their own solar power system and battery back up. While great in theory, we quickly realised that there were major inefficiencies in doing it this way and so came up with a suggestion modelled off what we had done in Tokelau but with a twist.

PowerSmart solution was to create a minigrid using multiple solar arrays all feeding into a single centralised battey bank that powered a reticulated grid that all the buildings were connected to. There a number of advantages to doing this:

  • With multiple arrays orientated in different directions a more constant supply of electricity is possible throughout the day
  • A centralised battery bank helps to eliminate inefficiencies compared to having individual batteries on each home
  • Because all the electricity generated by the solar PV is fed into a centralised pool of electricity, individual houses on the development can be charged for electricity. This gives the developer or manager of the resort another income stream.

In October 2016 Stage One was completed with over 300kW of solar PV panels and 2 Megawatt hours of Tesla industrial battery storage (Tesla powerpack). This is all backed by PowerSmarts own proprietary monitoring and control programme which ensures a constant supply of electricity to the grid.

This project also won 'Best Solar PV Off Grid Implementation' at the annual SEANZ (Solar Electricity Association of New Zealand) Awards in November 2016
