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
​
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.

MyMiniSolar 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.

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.

Ministry for Regulation launches formal review
The Ministry explicitly includes plug-in solar in its review of residential solar regulations — backed by David Seymour. This is what a year of advocacy helped make happen.

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.

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.
