Solar Inverters

Enphase Micro Inverters are a high quality, market leading micro inverter designed for optimised solar output and individual MPPT for shaded or difficult installations. Another benefit of the Enphase system is the ability to add panels at any time. Enphase have also released their own battery system, the Enphase AC Battery.

The ability to capture renewable energy for use at peak times when it is in high demand and expensive is essential in unlocking its ultimate value.

Enphase Microinverter

Built on the fifth-generation platform, the Enphase S230 Microinverter achieves the highest inverter efficiency for module-level power electronics. With its all-AC approach, the S230 simplifies design and installation, and delivers optimal energy harvest.

Pros of the Enphase IQ7+ micro inverter 

With micro-inverters, you don’t have to worry about how many panels you group together. 
This means they are less impacted by shading. 
They are also easier to expand. Start with one panel and one IQ7+ if you want. This allows you to offset a portion of your utility bill as soon as possible, then expand the system as budget allows.


Why use micro-inverters?
To answer this question, let’s look at the limitations of string inverters.
String inverters set restrictions on your panel string size—the number of panels that can be wired together and plugged into a single inverter input.
Panel strings typically contain 6-10 panels, which helps the inverter operate at peak efficiency. Too many panels (or too few) and your inverter won’t work properly.
The other major limitation is that panels in a string are linked together. When one panel in the string suffers reduced output (due to shading or technical malfunction), every panel in the string drops to match that reduced output.
You may own a string of 330W panels, but if a single panel in the string falls to 250W production, every panel in that string is going to produce 250W of power. That’s an 800W production loss over a string.

Micro-inverters are also the most shade-tolerant option. Shade on one panel will never impact the rest of your system. You don’t have to worry about a group of panels meeting a minimum string voltage, because each one functions as a self-contained system. 

10-year warranty -Optional 25-year warranty
This is a big one. The Optional 25-year warranty on the IQ7+ far surpasses the SMA Sunny Boy (10 years) or SolarEdge HD-Wave (12 years). That’s important because it matches the 25-year warranty that comes standard on Tier 1 LG solar panels in today’s market. With string inverters, you’ll need to budget for at least one inverter replacement over the life of the system. You’ll have to choose whether to pay more up front for an extended warranty, or cover the replacement out of pocket when the time comes.
The IQ7+ comes with a standard 10-year warranty. If one of your micro-inverters ever malfunctions at any point in your system’s lifetime, you’re covered for a free replacement. No maintenance fees or hidden ownership costs to worry about.

Your solar system size is quoted in kilowatts of power. But what does that have to do with your actual energy harvest in kilowatt-hours?

Watch how each solar panel of your system performs throughout a day: how quickly it switches on at the first rays of sunlight and how it maximises output despite scattered shade.

 

What our Clients Say

When we first started looking at getting solar panels for our home we knew very little about solar energy and there were so many different opinions and information on the topic which made it confusing.

I contacted Kane at Donna's Electrical to find out more info as they have a reputable name in our area. Kane was very helpful in explaining to me how solar panels work, the benefits etc. He answered all of my questions and also sent me tutorial videos on the panels they install which was quite handy.

After deciding we will go ahead with a solar system of our choice and size, Kane booked in a day to install the product. They were all done in one day and left the premises very tidy.

It has been several months now since and overall, our electrical bill has more than halved. That is the same for summer and winter. During summer I am able to run all irrigation, air conditioning and perhaps a washing machine and all of that power is covered with my solar panels, not costing me a cent.

I will most certainly add on to our solar system in the future and will without a doubt use Donna's Electrical for the job. I can highly recommend them.

Kane demonstrated a sound knowledge of solar generation and storage in designing a system to suit our requirements. He and his team did an excellent job of installation and persisted with a difficult commissioning due to our location having fringe connectivity. Very pleased with the result.

Brenton Newell | Wrattonbully

We had Donna’s Electrical install a 6kW solar system using LG 360 NeON panels & Enphase IQ7 micro-inverters with the system split on north & western aspects.

I chose Donna’s because the business ticked all of the boxes in what I was looking for; a reputable, local family owned business that’s been established a long time, which uses top quality products that come with industry best warranties.

Kane Donnelly was very knowledgeable, informative, helpful and worked on the install himself (no contractors involved in the process).Both he and his workers were friendly, professional and delivered a system I can be confident, will produce clean energy and deliver cheaper bills, long into the future; and if something does go wrong we have the best guarantees on offer.

Donna’s Electrical delivered a quality system on time, at a price I was comfortable with and I am happy to recommend them.

I would like to thank Donna Electricals, Kane and his Crew - Brett, Brad and Callan for the fantastic job at installing my solar system with the tesla battery backup system. Not only did the install only take 2 days, the whole crew were polite and helpful, answering any questions I had during the install. Kane your estimate on what my power needs would be and providing the system size accordingly was spot on.

The peace of mind I now have knowing that my backup battery will kick in at time of power outages is PRICELESS, working from home for a cloud based multinational company means I need uninterrupted power for the home office and indeed the internet, to run continually and efficiently, I now have that.

I am happy for Kane to post pictures of the install at my home and would be more than happy to provide a verbal recommendation for these guys.

I ended up looking into solar as an off grid solution when the price to get power to my house block was much more than expected. After doing some research and speaking to a few different solar providers I decided to go with Donnas Electrical. Hoping that by going local follow up service and quality of products would not be an issue, I had read plenty of horror stories. To be honest I could not be happier with my choice. Kane was able to supply a system to the budget I had in mind (which was quite a strict budget), on par with other quotes I had received and half that of getting the house connected to grid power. The installation was done to my time schedule and most importantly everything was very neat and tidy. Follow up service has been magnificent and I have no concerns that if I'm ever to have an issue they will be contactable. Every thing has worked exactly as it should and to the quality I expect. I would recommend dealing with the team at Donna's Electrical to anyone.

Thank you to Kane and the team at Donnas Electrical for the supply and installation of our solar and battery at Bordertown.  Your service and communication from start to finish was fantastic.  Loved also that the person who quoted did the installation.  

Ken & Veda Grey | Bordertown

Having solar panels installed was definately the best investment I have ever made and getting the Tesla Battery was the icing on the cake.  Finally in credit, yay one happy customer!

Ingrid Odd | Naracoorte

Having read information in the Advertiser and online, and having compared all the batteries available we decided that the Telsa 2 was the best battery for our 5kw solar system, A friend recommended Donna's Electrical to us after his installation, as he couldn't be happier with it. Donna's did all the paper work for the government subsidies etc and turned up and had the new battery fitted, wired to the internet and even put the app in our phones before they left. We are very happy with our system and are counting the savings using our own solar rather than having it go into the grid for chicken feed. We have already recommended Donna's to a neighbour who will have a new installation shortly.
