ABOUT US
We use what we sell.
MyMiniSolar Ltd. was founded by Gunnar Friese, who put a plug-in solar kit on his own place first (in Germany) and then went to fight to make it legal for everyone else in New Zealand.
Why we started
After installing plug-in solar on his own home in Germany, Gunnar wanted to do the same when he moved back to New Zealand. He assumed it would be simple, plug a small solar system into a normal power socket, just like millions of households across Europe. It wasn't. Plug-in solar hadn't made it to NZ, and after digging into why, he found out it was effectively prohibited. So he set out to change that and MyMiniSolar was born.
About a third of New Zealanders rent. None of them can install solar, not because the technology isn't ready, but because a rule written in 2012 never got updated to account for it.
In 2012, microinverters were a niche technology. The prohibition made sense then. Today, over a million of these systems are running safely across Germany. The technology moved on. The rules didn't.
MyMiniSolar exists to close that gap, by selling a product that's genuinely simple and safe and by being loud about the rule change that makes it possible.

What plug-in solar actually is
One to four panels. A microinverter. A standard NZ powerpoint. That's it. No scaffolding. No electrician visit. No $15,000 quote.
You plug it in, your fridge runs on sunshine and your power bill goes down. The inverter shuts off automatically if it loses connection, it won't backfeed into the grid unsafely and the plug pins don't stay live when you unplug it.
The technology is straight forward and the safety case is solid. Germany proved that at scale. What NZ needs is to review its regulations and that's exactly what we're working on.

Our advocacy
Fighting to make this legal — because it should be
We've been actively engaged in the regulatory process since day one. This is a classification problem, not a safety problem and we're working with regulators to fix it.
April 2025
MyMiniSolar Ltd. founded
Gunnar Friese starts the company after testing a plug-in solar system on his own home (in Germany) and realising there's no legal path to sell it in New Zealand — yet.
Mid 2025
The Advocacy starts
Gunnar starts engaging directly with the regulators who matter, WorkSafe NZ, the Electricity Authority, the Ministry for Regulation and Standards NZ, making the case that plug-in solar deserves its own regulatory pathway.
May 2026
Ministry for Regulation launches formal review
The Ministry explicitly includes plug-in solar in its review of residential solar regulations, backed by Deputy Prime minister David Seymour. This is what a year of advocacy helped make happen.
June 2026
WorkSafe Briefing Paper submitted
Gunnar submits a formal briefing paper to WorkSafe NZ covering the technology, safety mechanisms, international precedents and a clear regulatory pathway for NZ.
July 2026
Ministry for Regulation recommends legalising plug-in solar
On 30 July 2026, the Ministry for Regulation's formal review recommended legalising plug-in solar in New Zealand, proposing to amend the 2012 notice that banned it, update the Electricity (Safety) Regulations 2010, and develop a dedicated safety standard for plug-in systems.

Regulators adopt a plug-in solar framework and we launch
We're ready. The kits are selected, tested and priced. The moment the rules catch up, we'll be first in market with a product we've already put our name behind.
