P-series-inverter

Product profile: new grid-interactive inverter range

Share : Share on FacebookShare on Google+Pin on PinterestTweet about this on Twitter

It seems that there’s a vast range of grid-interactive inverters to choose from nowadays, and that range just increased with the P series inverters from SolarMax.

READ MORE »

The range consists of five new models—2000P, 3000P, 4000P, 4600P and 5000P, all of which have a 120 to 600 VDC input voltage range. The transformerless inverters have been optimised to deliver maximum energy efficiencies of up to 98%. The three largest models have dual maximum power point tracking inputs that can be operated in either dual or single tracker mode, making the inverters suitable for split solar arrays with different orientations.

The inverters use passive cooling, so there are no fans to worry about, and owners can monitor the performance of their PV system using the web- and app-based application MaxView by simply connecting the inverter to any standard internet router using an ethernet interface.

All SolarMax P series inverters are battery ready and may be upgraded at a later stage with the addition of the P-Battery upgrade kit. This offers owners the ability to incorporate storage systems without the need to replace the inverter itself.

RRP: POA. For more information contact Sputnik Engineering Australia & NZ, Level 13/Office 1329, 167 Macquarie St, Sydney NSW 2000, ph: (02) 8667 3168, info-au@solarmax.com, www.solarmax.com/au/en/

Share : Share on FacebookShare on Google+Pin on PinterestTweet about this on Twitter

When most people think of portable power supplies, they think of a genset. But gensets require maintenance and fuel, and are quite polluting, especially when run at low loads, as most are for a large percentage of their runtime.

READ MORE »

Ecoboxx provide a great alternative with their portable solar power systems. Just set up the panel, connect it to the main Ecoboxx unit and you are done.

There are three models—the 160, 600 (to be released in August) and the 1500. They feature 100, 600 and 1500 watt inverters respectively, with the two larger models having sinewave outputs. Storage capacities are 13 Ah and 45 Ah at 12 V for the 160 and 600 respectively using sealed AGM batteries. The Ecoboxx 1500 can use batteries from 100 Ah to 300 Ah, but it is supplied without a battery as standard. To make the most of the solar panels, the Ecoboxx 1500 also features a MPPT solar charge controller.

The solar panels for each unit are rated at 20, 80 and 130 watts respectively (the 1500 can handle up to 300 watts in total) and each Ecoboxx comes with a 3W LED bulb and lead set, and an AC charger, for when you need to charge the unit from mains power.

RRP: $299 for the Ecoboxx 160 and $1299 for the Ecoboxx 1500. The 600 will be priced around $800 when released. For more information and to find your closest dealer, contact Ecoboxx, ph: (02) 9724 3344, info@ecoboxx.com.au

Gleamous

Product profile: Gleaming hot water

Share : Share on FacebookShare on Google+Pin on PinterestTweet about this on Twitter

Continuous flow or instantaneous hot water systems are usually gas powered, but there’s an ever-increasing range of electric units on the market. These are suitable when there is no mains gas available (running water heaters on LPG can be expensive) and, being electric, there is no wastage due to continuously running pilot lights.

READ MORE »

The range of electric instantaneous hot water systems from Gleamous solve the problem of no gas availability and can provide hot water without the water wastage of running hot water from storage tank systems. The smaller units are ideal where hot water is needed a long way from the hot water system, such as a second bathroom, shed or workshop. The larger unit can provide hot water to an entire home without the standing losses of a storage type system, or the accompanying maintenance, such as replacing PTR valves and sacrificial anodes every few years.

There are three models in the range, two of which have no storage (the 3.3 kW, single-phase DSK-45EP and the 14 kW, three-phase GL5) and one which stores five litres of water at the point of use (the DSL-30N).

Leaf safe guttering

Product profile: Finally, a leaf guard that works?

Share : Share on FacebookShare on Google+Pin on PinterestTweet about this on Twitter

While leaf guard systems for gutters sound like a great idea, the reality is that almost all of them suffer from problems of clogging—especially when gumnuts are involved. Leaf Safe Guttering is a new gutter system designed to eliminate the problems found with previous leaf guard systems.

READ MORE »

The Leaf Safe Guttering system sits below the outer edge of the roof and is completely enclosed on top by a sloping lid that prevents leaves and debris falling into the gutter. Rainwater flows over an outer vertical gutter face that has two staggered sets of perforations which still have the upper flaps attached and turned inside the gutter. The flaps guide the water flowing over the vertical edge of the gutter into the gutter trough, while the leaves and other debris continue to flow downward and off the outside of the gutter.

Leaf Safe Guttering is made from Colorbond steel and is available in the full range of Colorbond colours. The guttering can be made to size and shipped anywhere in Australia to be fitted by local guttering installers.

Product profile: Great coffee, less energy use

Share : Share on FacebookShare on Google+Pin on PinterestTweet about this on Twitter

Home espresso machines have become more popular in recent years. But while they can allow you to make a real coffee at home, they use a lot of energy per cup, take up bench space and, like many home appliances, contain a lot of materials for the simple job they do.

READ MORE »

The ROK Espresso Maker from Presso Ltd is a compact espresso maker that is almost completely human powered. The only energy input is to make a small amount of boiling water—the rest is done using elbow grease.

The unit is made almost entirely from high-grade metal, making it almost completely recyclable, and being far smaller than an electric coffee machine, it is ideal for homes with limited space and for people on the move.

The ROK comes in a reusable metal storage tin and includes all needed accessories: Portafilter, stainless steel milk frother, single espresso splitter, tamp/spoon and instruction booklet. It comes with a ten-year warranty.

RRP:$250, although at time of writing it was on sale for $187. Made by Presso Ltd, www.rokkitchentools.com and available in Australia from Espresso Unplugged, PO Box 724, Mullumbimby NSW 2482, ph:(02) 6684 9400, info@espressounplugged.com, www.espressounplugged.com.au

Share : Share on FacebookShare on Google+Pin on PinterestTweet about this on Twitter

Carbon dioxide is normally considered an environmentally damaging gas, being the main greenhouse gas causing climate change. However, it also has its good sides—it makes a great refrigerant.

READ MORE »

Sanden has used this property in their new heat pump water heater to produce what is arguably the most efficient water heater available in Australia.

The Sanden Eco has a rated coefficient of performance of 4.5, meaning that it uses as little as 22% of the energy of a regular electric element heater. It also features a fast recovery time of four hours when heating water from 17 °C to 65 °C.

The Eco comes with a 315 litre stainless steel tank and has an operating temperature range of -10 °C to +43 °C, making it suitable for use in frost-prone areas. Noise levels are rated at 38 dB. The system comes with a three-year warranty and the tank has a huge 15-year warranty.

Other features include a split system design, so that the heat pump and tank can be up to four metres apart and the option of two different tank shapes to suit the available space—tall with a reduced diameter or short with an increased diameter.

Classic_LITE

Product profile: See the MidNite Lite

Share : Share on FacebookShare on Google+Pin on PinterestTweet about this on Twitter

The MidNite Solar Classic range of MPPT solar regulators are quite popular, but they are not the lowest cost regulators on the market. To address this, MidNite Solar has released a somewhat lower cost Lite version.

READ MORE »

The Classic-Lite version includes almost all the features of the regular model, except for the LCD and arc fault detection.
Features include up to 250 V input, current controlling capacity of up to 96 A of solar, wind or hydro on a 12 V battery (or up to 5 kW on a 48 V battery), ethernet port and 380 days of data logging.

By dropping the LCD and arc fault detection, the cost of each model has been reduced by around $150 over the equivalent full Classic model.

Simple programming is done via DIP switches and more complex programming via the ethernet port and the included free PC software. User feedback is via LEDs and a manual equalise button (auto-equalise can be programmed via a PC).

The new Classic-Lite allows relatively inexpensive grid-connect type solar panels to be used on any independent power system where high levels of user information are not needed, such as on mobile and marine systems or weekenders.

RRP: $849 (inc GST) for the 150 V model. For more information and to buy, contact DC Solutions Australia, ph:(03) 9482 7744, info@dcsaustralia.com.au, www.dcsaustralia.com.au

Core power

Product profile: Who needs petrol!

Share : Share on FacebookShare on Google+Pin on PinterestTweet about this on Twitter

Until the advent of high capacity lithium batteries, attempts by makers of power garden tools to create alternatives to petrol-powered machines had been lacklustre at best. Nowadays, in the realm of weed trimmers, the best readily available in Australia appears to be the Stihl FSA85. But at $349 plus around another $400 for the battery and charger, it is expensive.

READ MORE »

As an alternative, the CGT400 trimmer from Core Outdoor Power in the USA uses Core Power’s new motor design that has no wire windings at all. Its pancake motor uses high powered magnets on the rotor and a heavy duty circuit board as the stator. The result is a very compact, very efficient motor with enormous torque.

There are two settings, the 5000 rpm ‘torque’ setting and the 7000 rpm ‘speed’ setting. The motor has a rated life of 10,000 hours and run time is up to 70 minutes. The CGT400 features a dual 2.4 mm line bump-feed head and comes with battery and three-hour charger (120 volt only, so you will need a step-down transformer).

Having used the CGT400, we can say it is by far the most powerful rechargeable trimmer we’ve come across and is very quiet.

RRP: US$299 including battery and charger. Ours cost US$259 from www.mowersdirect.com (currently $279) and around $300 to ship to Australia. For more information go to www.coreoutdoorpower.com

Aeratron black

Product profile: Super low energy ceiling fans

Share : Share on FacebookShare on Google+Pin on PinterestTweet about this on Twitter

Ceiling fans are one of the most efficient methods of providing a cooling effect, but many are noisy, they wobble and they still use a lot more energy than they should for the job they do.
Aeratron fans have been designed not only to look great, but also to use very little energy while helping to keep you cool. They are available in two-blade (e502) and three-blade (e503) versions, in white, black and silver finishes.

READ MORE »

Rated power consumption of their DC motors is less than four watts on the lowest of the six speed settings, while maximum speed uses just 18 watts. Regular fans of this size can use 60 watts or more, so there’s no doubt the Aeratrons have been designed for high efficiency.

Fan rotor diameter for both models is 1260 mm and the six-speed controller also has a reverse function for pushing warm air from the ceiling down to floor level during winter.
To improve the fans’ eco-credentials further, Aeratron has worked to reduce waste during production, the fans are supplied in ‘eco-packaging’, and carbon offsets are used to reduce their carbon footprint.

RRP: $367.50 for the e502 and $389.50 for the e503. Available directly from Aeratron, ph:(02) 9365 6470, info@aeratron.com.au, www.aeratron.com.au or Lighting Illusions, www.lightingillusions.com.au
