Solar Infographic : If Inverters were Cars…

The current edition of industry bible “Photon Magazine” (June 2012 issue) has a glowing review of the Chinese made Samil Power Solar Lake 15kW inverter.

A couple of years ago if you were investing in a 15kW solar system your default choice would have been a European inverter – think SMA, Aurora or Delta. It would have been a very brave engineer that specced a Chinese inverter on such a big system!

However in a few short years the Chinese have learned from any mistakes made and are producing some world class solar inverter hardware.

What you need to know about solar inverters and RF interference

May 11, 2012 2017-05-01T15:53:03 by 36 Comments

A solar inverter is like any other electronic device in your home and it will produce some Electromagnetic radiation and potentially Radio Frequency interference. There is a standard that all approved electrical devices in Australia are required to meet (C Tick) but it does not guarantee zero emissions.

Solar is compatible with 3 phase

There is an awful lot of confusion (and misinformation) out there about the practicalities of installing solar on a house that has a 3 phase supply. So I’ve written this post to clear up the confusion. [Read more…]

SunGrow Inverter beats SMA in Latest Inverter Reviews

Chinese Sungrow Vs German SMA Inverters: Which ones are best?

Note: This post is just one opinion on Sungrow Inverters. Click here for lots of Customer Reviews of Sungrow Inverters to see how they have performed in Australian homes over the last few years.

If you are considering buying a Sungrow Inverter over an SMA inverter – then you should also check out customers’ SMA reviews. You’ll see that, in practice, SMA inverters are more reliable. This is to be expected, since SMA are double the price of a Sungrow!

Now back to the post…

Yesterday I received my latest issue of the solar industry bible, Photon International  via airmail all the way from Germany. Whilst many people may get excited by the latest issue of Top Gear Australia magazine or Better Homes & Gardens, I’m one of those odd people that gets my kicks looking through the latest solar panel and inverter specs.

Samil Inverter Review: German magazine gives top marks

March 13, 2012 2017-05-02T10:48:08 by 20 Comments
Samil Power Solar River Inverter

The Samil Inverter got a great review in the German Photon Magazine in August 2011

Samil Inverters are very popular in Australia. They are great value, and have great specifications on paper. However I get a lot of emails asking me if this Chinese made solar inverter is any good.

It is a fair question. The inverters are a lot cheaper than their German made competition (like SMA), and are a relatively new player in the market. Plus there are a lot of solar salespeople out there that are peddling the (somewhat xenophobic) line that all Chinese made solar components are crap.

So what’s the truth? Are Samil Inverters any good? [Read more…]

Don’t mount your inverter where the sun can cook it!

If you’ve been reading this blog for any length of time you are probably already aware of how high ambient temperatures negatively affect solar panel performance.

But did you know that when it gets hot outside, those scorching Aussie temperatures can also cause the efficiency of your solar inverter to drop? [Read more…]

Two Reasons You Must Look At Efficiency Curves When Choosing Your Solar Inverter

January 29, 2012 2019-02-08T13:45:51 by 17 Comments

In my last blog post I explained how to find an inverter’s real-world efficiency instead of relying on the inverter manufacturer’s  numbers.

The CEC or European Efficiency numbers that I talked about are a much better number to use when comparing solar inverters. And for most people they will be all you need. However if you really want to understand how your solar system is going to perform then you should also look at the inverter’s “efficiency curve”.

Your inverter does not simply have one efficiency that it always operates at. The efficiency of your inverter will depend on two minor factors and one major factor.

Solar Inverter Efficiency: What you need to know before buying.

January 28, 2012 2014-01-05T18:42:50 by 1 Comment

Everything goes through the inverter so its efficiency is critical.Solar inverter efficiency is a critical specification that directly affects the efficiency of your entire solar system. It is almost always a much more important consideration than solar panel efficiency.

All the power generated by your solar panels has to go through your inverter before you can either use the power in your home or export it to the grid (and get paid) so every percent of extra efficiency that you can squeeze out of your inverter will directly improve the performance and payback of your solar system.

So do you just need to pick the inverter with the highest “efficiency” number on the specification sheet? Well I’m afraid it isn’t quite that simple. (You guessed I was gonna say that didn’t you?!) [Read more…]
