We are not tied to one manufacturer. What each part of a system does and where it goes, then the brands we fit and why.
A complete system is four pieces of equipment doing four different jobs. Here is each one, what it does, and the brands we fit. We are not tied to a manufacturer: what you will never get from us is a brand chosen because it was in the van.
The generating part, and the one that has to survive thirty years of Canterbury weather without anyone touching it. Efficiency matters most when roof space is limited.
Back-contact cells, which move the electrical contacts to the rear so nothing shades the front of the panel. Full-black, among the highest efficiencies available, and covered by a 30-year product and performance warranty: a manufacturer betting on its own product.

Our alternative where it is the better fit for a project: budget, availability or a particular system design. Same design, install and sign-off standards either way, and we will always say which panel we are quoting.
Compare the twoThe brain. It converts DC to AC, decides what goes to the house versus the grid, and reports the lot to your phone. It also sets what the system can grow into later.
A strong all-rounder on New Zealand homes, with a hybrid range that is battery-ready from the start and its own matched battery. Well supported locally, which matters years down the track when you need firmware or a part.
More on inverters
One of the largest inverter manufacturers in the world, with a range that runs from a single-phase house up to a three-phase commercial site. Where a job needs scale and a long service life, this is usually the shortlist.
More on inverters
The premium end. Austrian-engineered, with a long-standing reputation for durability and serviceability rather than for being the cheapest option on a quote. Chosen when a client wants the inverter to be the last thing they think about.
More on inverters
Inverter, battery and EV charging designed as one stack rather than three products bolted together. Fewer boxes on the wall, one app, and a straightforward upgrade path if you add storage or a car later.
More on invertersWhat decides whether your solar is worth much after 4pm. Without it, daytime surplus is exported cheaply and bought back at dinner time at the retail rate.
The best-known home battery, and the one most people ask for by name. We are a Tesla Powerwall Certified Installer, which means Tesla has trained and signed us off to design, install and commission it, not just to resell it.
More on batteries
Stacks in modules, so you can start with the capacity you need and add to it rather than replacing the unit. Pairs with the matching inverter for one integrated system and a single app.
More on batteries
The natural pairing where the inverter is already SolaX: one manufacturer end to end, one warranty conversation, and no doubt about whether the two halves will talk to each other.
More on batteries
Widely used, well proven and highly configurable, which is why it turns up on off-grid and rural jobs where the capacity has to be built to the property rather than picked off a shelf.
More on batteriesThe biggest single load most homes ever add, and the one that pairs best with solar. A smart charger can be set to draw only from surplus generation.
A wall-mounted charger on its own certified circuit, sized to your switchboard's spare capacity. Where you already have solar, a smart charger can be set to pull from surplus generation rather than from the grid.
More on EV chargers
Three-phase chargers and multi-bay installations for staff parking and fleet yards, including load management so a row of chargers does not trip the site's incoming supply. Commercial solar and fleet charging are a natural pair: the cars are parked there all day.

Ask Us What FitsBeing independent of any single manufacturer is the point. A north-facing Christchurch roof with a heat pump and an EV needs a different system to a shaded Rangiora bungalow or a Selwyn dairy shed.
We select gear with warranties worth having, and we handle the claim if something fails inside its coverage period.
Brands with real support in New Zealand, so parts and firmware are still available years after install.
Panels, inverter, battery and EV charger specified to work together, so you monitor the whole thing in one place.
That is what the free assessment is for. We will spec it properly and explain why.
