How it works
How ELVO Solar Works — Built for Rural NZ Conditions
Correctly Sized Solar Panels Each system uses a panel matched to real NZ daylight hours — not the undersized panels found in cheap imports. This means reliable charging even in winter.
Long‑Life LiFePO₄ Batteries Our batteries are rated for up to 8,000 cycles (around 20 years). They handle frost, cold mornings, and long nights without losing performance.
Smart Control System Turn lights on or off from inside your home, shed, or workshop. Long‑range radio control means no walking across the property in the dark.
Rural‑Ready Design Every component is built for wind, rain, frost, and exposed rural environments. No trenching, no wiring, no mains power needed.
Consistent Light Output Because the panel and battery are correctly sized, your lights stay bright — not dimming after a few hours like typical solar lights.

About us
Who We Are
Senztek NZ Ltd is a New Zealand electronics design and manufacturing company based in West Auckland. For over 20 years, we’ve built reliable electronic systems for hot water management, industrial instrumentation, and precision power — products trusted across New Zealand and around the world.
Our Focus
We specialise in practical, alternative‑energy solutions that make everyday life easier and more efficient. Our work in water heating and solar technology led naturally to developing ELVO — a range of extra‑low‑voltage solar lighting and power systems designed for real NZ conditions.
The ELVO Difference
Every ELVO product is built around a long‑life LiFePO₄ battery with an integrated management and charging system. This battery chemistry is stable, non‑flammable, frost‑tolerant, and free from cobalt and rare earth metals — making it safer for people and better for the environment.
We design ELVO systems to be:
- Safe — no mains power, no electricians required
- Easy to install — no trenching or wiring
- Durable — engineered to last over 20 years
- Reliable — built for NZ’s cold mornings, long nights, and harsh weather
Made in New Zealand
All ELVO batteries and switches are manufactured and individually tested at our Avondale factory. We believe in building products that last — not disposable gadgets — and we stand behind every unit that leaves our workshop.
