ACMA audited solar inverters for electromagnetic compliance. The worst thing they found? Missing stickers.

We’re so accustomed to seeing electrical products with compliance stickers and certificates, it’s a safe bet that most of us barely notice them. So here’s a handy reminder that those stickers and certificates matter. [Read more…]

There are a lot of solar inverter brands on the Australian market in 2021. But which ones are the best?

That’s a tough question to answer. So we asked installers we trust what they thought. [Read more…]

With this week’s launch of the Internet of Things Alliance Australia’s (IoTAA) security awareness guides, this seems a good time to remind the solar industry that we’re part of the Internet of Things – and so far, we seem to take a pretty relaxed attitude to security. [Read more…]

Big inverters are much cheaper per Watt. Another reason to go big with your solar power system.

When people ask me how much solar they should put on their roofs, I usually reply along the lines of…

“As much as you bloody well can.”

I’m not saying you should borrow money from the mafia or a dodgy finance company to do this. Still, I recommend putting on as many solar panels as is reasonable given the constraints of budget, roof space, and how much they’ll let you install in your area. [Read more…]

Many Australian homes are not allowed to export more than 5 kW to the grid. If they want a big solar system with an inverter larger than 5 kW, they must ‘export limit’ the inverter. Here’s what that means. [Read more…]

When I asked Solar Analytics’ head of business development Nigel Morris for a chat about the company’s partnership with Sungrow, I didn’t expect to end up in a conversation about system interoperability and standardisation. [Read more…]

If SA needs to hit the big red button and shut down rooftop solar installed after 28 September 2020, SMA inverters can comply – at no extra cost to the owner.

On Thursday I was invited to a webinar on SMA’s response to South Australia’s new solar inverter requirements.  It seems that SMA — the maker of Sunny Boy inverters — was on the ball as all their residential inverters are on SA’s approved installation list. [Read more…]

Yesterday in SA, solar met 100% of demand for a short period. Hence the need for remote curtailment of new solar. SolarEdge inverters can meet this requirement. Image: Rob Morris

Update 14th December 2020:  Good news!  SolarEdge has informed me they no longer charge an additional $165 to cover the cost of meeting South Australia’s new inverter requirements.  SolarEdge instead now absorbs the cost, which is obviously good news for anyone thinking of getting a SolarEdge system in SA.

On Thursday at 3:58 pm I was invited to a SolarEdge webinar that started at 4:00 pm.  I was glad to get the invite, but the lack of notice meant I missed out on the first 5 minutes because I didn’t have time to set up my laptop/internet properly beforehand.  This was very appropriate because the webinar was about how SolarEdge had responded to new South Australian solar inverter requirements that were rushed in before the industry had time to properly prepare.  [Read more…]

Friends, it’s arrived: the Australian Energy Market Operator has published its standard low voltage ride-through test procedure for inverters. [Read more…]

Thanks to a deficit of trust in government, people are rightly worried when they hear that ‘the government wants to be able to switch off their solar systems’.

On the 30th of April the AEMO or — as it’s known by the long-winded — Australian Energy Market Operator, published a significant report called Renewable Integration Study 1.  A few people read the summary and then wrote articles on how the grid wants to take control of people’s solar inverters; switching them on and off as they desire.
