Custom 48V Power Stations, Built for the Job
High-power 48V systems, built your way — from clean, pre-wired boards ready to drop into your build, to fully engineered power cabinets for indoor or outdoor installation. Designed, assembled and commissioned in our Christchurch workshop.
Two Ways to Build It
One Platform, Two Ways to Get It
A 48V power station brings the whole system together — inverter/charger, solar, DC-DC charging, monitoring and protection — as one properly engineered unit. Whether you want a tidy board to integrate into your own build, or a complete, self-contained cabinet ready to install, we build both.
Option 1 · Efficient
Pre-Wired Boards
The core system, cleanly assembled and wired onto a mounting board — ready to drop into your van, trailer or build. The fast, tidy, repeatable way to get a proven 48V layout.
- Inverter/charger, MPPT solar & DC-DC on one board
- System monitor and battery protection integrated
- Tested and configured before it leaves the workshop
- Flexible mounting — behind a cabinet, in a compartment
- Faster to fit, clean and serviceable
Option 2 · Premium
Custom-Built Cabinets
The same power, built into a finished, enclosed power station — engineered for permanent or semi-permanent installation, indoors or out. A complete, protected, self-contained unit.
- Fully enclosed, protected and labelled
- IP-rated for indoor or outdoor / exposed use
- Proper ventilation and thermal management
- Built to move between vehicles or sites if needed
- Engineered around your exact space and loads
Option 1 — Pre-Wired Boards
A Proven Layout, Ready to Fit
A pre-wired board takes all the core components — inverter/charger, solar controller, DC-DC charging, monitoring and protection — and assembles them onto one tidy, tested board. Instead of wiring a dozen loose components into a bulkhead, you get a single, proven unit that's ready to mount and connect.
- Everything integrated — the whole 48V system on one board, wired and labelled.
- Tested before it ships — configured and checked in the workshop, not on your driveway.
- Clean and serviceable — a logical layout you (or any tech) can work on later.
- Faster to install — mount, connect your battery, solar and loads, and go.
Option 2 — Custom Cabinets
A Complete Power Station, Enclosed & Engineered
Take that same system and build it into a finished cabinet, and you get a self-contained power station — protected, tidy, and ready to live wherever it needs to. Ideal for expedition builds, external compartments, mobile commercial setups, or anywhere the system needs to be sealed away from dust, weather and knocks.
- Indoor or outdoor — IP-rated to suit where it lives (sheltered through to fully exposed).
- Kept cool — proper ventilation and thermal management so it runs reliably.
- Protected & secure — sealed against dust and moisture, lockable where needed.
- Portable if you want — built to move between vehicles or sites.
The Engineering
More Than a Box of Parts
Whichever route you take, the details are what make it last. This is where a built-and-commissioned system beats a bag of components every time.
Sized to Your Load
Inverter, battery and solar capacity matched to what you actually run — with headroom, not guesswork.
Thermal Management
Batteries and inverters make heat — we design ventilation and clearance so the system stays cool and reliable.
Protection & Fusing
Correct busbars, fusing and circuit protection throughout, rated for high-current 48V and labelled clearly.
Monitoring Built In
A system monitor so you can see charge, usage and health at a glance — on a display or your phone.
Charge From Anywhere
Solar, shore power and vehicle charging combined, so the station stays topped up however you're using it.
Built to Standard
Assembled, wired and commissioned to AS/NZS requirements — then tested and handed over documented.
High-power 48V systems and any 230V output carry real safety and compliance obligations — the
solar side alone can reach dangerous voltages. These are designed and built as engineered systems, not
DIY kits. We'll confirm the right components, enclosure and layout for your application when you enquire.
Who It's For
Built for Serious Power Needs
Expedition & Overland
Self-sufficient builds that need serious, protected power a long way from anywhere.
Large Vans & Trailers
Big rigs running high-demand appliances that a standard 12V board can't keep up with.
Mobile Commercial
Coffee vans, food trailers and mobile trades that need reliable, self-contained power to work.
Fixed & Off-Grid Sites
Sheds, cabins and remote sites that want an enclosed, weatherproof power station built to last.
