SolarEdge HD Wave Review:  The World’s Smallest And Most Efficient String Inverter

Today Ronald examines the SolarEdge HD Wave inverter. It’s small. But not that small.

It’s An Itsy Bitsy, Teeny Weeny, SolarEdge, HD Wave String Inverter…

SolarEdge, an Israeli company, has produced the HD Wave — the world’s smallest string inverter.  By size, this little cracker takes more DC than any inverter out there.  Not only that, but it grabs DC, uses its funky HD wave technology on it, and spurts out the AC our homes use with greater efficiency than any thing else on the market.  And it’s now available in Australia, starting from a couple of weeks ago.

Tesla Kills Off DC Powerwall 2. AC Powerwall Delayed

powerwall 2 DC is dead

DC’s not pinin! DC’s passed on! This battery system is no more! DC has ceased to be! It has expired and gone to meet its maker! DC’s kicked the bucket! DC has shuffled off its Tesla coil, run down the charge, and joined the bleedin’ choir invisible! THIS IS AN EX-BATTERY!

I was just relaxing by listening to the musical version of the Massacre of Mankind when I suddenly got some news from the solar grapevine1 concerning the Tesla Powerwall 2.  To cut a short story even shorter:

The DC version of the Powerwall 2 is dead!

Long live the AC version!

If it ever gets here!

Has Maxim Just Killed The Microinverter & DC Optimiser?

3 maxim chips compared to a micro inverter and dc optimiser

Are these 3 little chips all you need to optimise your panels for maximum energy output?

Maxim Integrated is a Californian electronics company that has been going strong for 33 years and has only ever been delisted from the Nasdaq Stock Exchange once.  As you may be able to tell from their name, they like to integrate things and have developed a way to optimise the power from individual solar panels using 3 tiny chips embedded in the panel.

Microinverters Vs. Dc Optimisers: Which option is best?

optimisers and microinverters

If you’ve decided on panel-level optimisation, which is the better choice, microinverters or optimisers?

Good grief this article is going to get me into trouble with some solar installers.  Why? Because by the end of it I will give my humble opinion on whether microinverters (e.g. Enphase) are better than DC optimisers (e.g. SolarEdge or Tigo). [Read more…]
