Power-One Inverters

Power-One is now the world's second-largest inverter manufacturer, and these inverters are a standard in Europe, where they used to be sold under the highly respected Magnetek name until this Italian company was bought by US-based Power-One.

The Power-One Aurora wind inverters have their own page - Click Here!


Power-One Solar Grid-Tie Inverters

The Power-One Photovoltaic Aurora grid-tie inverters are available in 3kW, 3.6kW, 4.2kW, 5kW, and 6kW output power for single-phase/split-phase, plus 10kW and 12kW output power for three-phase. That makes it easy to find just the right size for your project. The inverters have a build-in DC disconnect.

For the larger projects Power-One also makes a line of central inverters in 50kW, 100kW, 250kW and 300kW output power (all 3-phase).

The single-phase inverters are intended for 240V split-phase, 208V single phase, or 277V single-phase (the last two are one leg of a 3-phase circuit). The three-phase inverters are meant for 208V, 480V, and 600V. The string inverters and some of the central inverters are made in Ontario, and qualify for FIT/MicroFIT Domestic Content.

There are a number of features that place these inverters a step above the pack, but do not take our word for it, see the Photon Magazine test (and despite the article's title the Aurora inverters are really easy to install and use). Here are the main features that make the single-phase inverters tick. The three-phase inverters are slightly different, please see the spec sheet on the left:

  • Every inverter has two independent MPPT inputs. This allows you to split the PV modules into two arrays, based for example on orientation, or shading, and hook up each section to its own input. The inverter will track the optimal power point for each of the two arrays independently. Of course, both inputs can be combined and used with a single array as well. Having two inputs means electrical code allows 4 PV strings to be connected without the need for overcurrent protection, and that means you will virtually never need a combiner box.

  • The highest efficiency in the business. The Power-One solar inverters have a CEC weighted efficiency of 96% (for the PVI-5000 and PVI-6000 it is 96.5), and a peak efficiency of 96.8% (for the PVI-5000 and PVI-6000 peak efficiency is 97%). Efficiency is virtually flat from 30% through 100% of rated power. That is as good as it gets! Combine this with an extremely low night-time loss of just 0.24 Watt and you get  more energy to feed back into the grid, and happier customers.

  • Ultra-wide MPPT range. These inverters will do maximum-power-point-tracking from 90 through 580 Volts, with the full power output range starting at 120 ... 170 Volts (depending on model). This makes it easy to configure PV arrays and stay within range, even on those very cold winter days. This also makes it possible to fit your array within one or two strings per inverter MPPT input and avoid the use of a combiner box.

  • The fastest MPPT algorithm in the industry.  The algorithm in the Aurora inverters tracks the changes in optimal power point within 1.4 seconds of input changes. This makes it by far the fastest MPPT tracking algorithm in the industry, resulting in higher production under difficult conditions (such as when multiple clouds pass in front of the sun).

  • Power to spare! For example, while billed as a 3.6 kW inverter, the PVI-3.6 has a maximum input rating of 4.15 kW. Maximum AC output power for this inverter is 3.96 kW! This adds to flexibility in sizing and energy production, also on those very cold and sunny winter days that push the edge of the envelope.

  • Full rated power up to an ambient temperature of 50C (122F). Power-One inverters use free convection for cooling. That means improved reliability compared to fan cooled inverters, and higher production on hot summer days.

  • Can be mounted outside in the rain. All models use an IP65 / NEMA-4X type enclosure. These are watertight enclosures that can be mounted inside or outside.

  • Built for reliability. The design, construction, and component choice of these inverters is optimized for a long service life, even under harsh environmental conditions. For example, they use fewer electrolytic capacitors than usual, and the remaining ones are long-life high temperature types.

  • UL1741 and CSA C-22.2 listed. 10 year warranty standard, 15 and 20 years optional.

PVI Desktop MonitorPower-One PVI-Desktop Monitoring

For local monitoring of up to 6 inverters Power-One provides a cost-effective solution through the PVI-Desktop device. The PVI-Desktop is intended for the kitchen countertop, and it can talk to the inverters either wired or wirelessly. It provides the essential information, such as current power, daily/weekly/monthly energy production etc. through a 3 color touch-screen. This makes it very simple to use, ideal for the home owner who wants to keep an eye on their solar PV array.


Power-One (Aurora Universal) Web Monitoring

Aurora Universal offers a scalable Web monitoring solution that works from their smallest 3kW inverter to the largest multi-MW solar plant with central inverters. Fat Spaniel is a leading edge company that specializes in Web monitoring of renewable energy generators. Power-One is now the owner of Fat Spaniel, and offers its services for their own inverters, as well as a wide array of other brands. The solution for Power-One inverters goes under the name "Aurora Universal". It is subscription based, where the hardware includes a subscription for the duration of the warranty of the inverter(s), including any extended warranty purchased by the subscriber.

The Aurora Universal hardware and service comes in three variants: Aurora Universal Residential, Aurora Universal Industrial, and Aurora Universal Revenue Grade. Up to 15 inverters can be daisy-chained through RS485 and connected for monitoring to a single Aurora Universal unit. The residential and industrial versions are identical, except that industrial comes with a NEMA-3R enclosure for mounting outside (you could mount the residential version in a similar enclosure yourself and have the same functionality, see the manual for the Industrial version to get the idea). The revenue grade version comes with more hardware to more accurately measure energy production, and is primarily intended for large solar plants. In addition to the default hardware, there is an optional Environmental Appliance. This comes in several version, depending on the included sensors, and adds monitoring of ambient temperature, panel temperature, solar radiation, humidity, pressure, wind speed and direction, and rain.

The default Web interface goes under the name Aurora Vision. It provides plenty of information for the average user's needs. For those that need a more specialized Web interface (such as a kiosk function, various alarms etc.) there are a la carte development services available for a reasonable price that will tailor the Web interface exactly to your needs.

You can test-drive the Fat Spaniel and Aurora Vision system for yourself by logging in to Power-One's own (live) monitoring pages:
