Our strength lies in deep technical expertise, local manufacturing and integration capabilities, and a proven track record supporting Tier 1 telcos, government networks, defence, and transport sectors.

Backed by a dedicated team and a strong commitment to innovation, we deliver tailored, high-quality solutions ranging from DC power systems to solar hybrid and BESS configurations, supported by dependable pre- and post-sales engineering services.

Versatile and scalable DC power systems play a vital role in supporting telecommunications infrastructure across New Zealand, from compact installations to large-scale networks. Designed for efficiency, reliability, and durability in demanding environments, these systems help minimise downtime and reduce operational costs.

With flexible configuration options, support for renewable integration, and full engineering assistance from design through to maintenance, DC power systems deliver long-term performance and continuity for critical telecom operations.

Solar hybrid systems offer a reliable and environmentally friendly power solution for remote telecommunications sites, ensuring consistent connectivity even in challenging conditions. These systems can be integrated with existing infrastructure and tailored to site-specific requirements, combining advanced solar panels, battery storage, and smart energy management to reduce costs and environmental impact. With real-time monitoring and remote control capabilities, solar hybrid solutions deliver efficient, resilient, and sustainable power for modern telecom networks.

Reliable batteries are essential for maintaining uninterrupted telecommunications services, especially during outages or in off-grid conditions. A broad range of options, including advanced lithium-ion batteries from Polarium and trusted VRLA lead acid solutions ensures the right fit for any operational requirement or budget. With benefits like fast charging, long lifecycles, and smart energy management, these battery systems support continuous operation while reducing environmental impact. Expert support is available from selection through to maintenance, ensuring dependable performance over the long term.

Battery Energy Storage Systems (BESS) play a key role in modern telecommunications by improving energy reliability, reducing grid dependence, and optimising power use through peak shaving. Suitable for everything from small sites to large networks, BESS solutions enhance uptime, lower operational costs, and enable participation in distributed energy markets. With the added benefits of renewable energy integration and expert engineering support, BESS helps telcos build resilient, efficient, and future-ready power infrastructure.

EFOY direct methanol fuel cells provide reliable, low-emission backup power for telecommunications, offering a quiet and efficient alternative to diesel generators—especially in remote or solar-reliant sites. These scalable systems integrate easily with existing infrastructure and operate autonomously, ensuring uninterrupted connectivity even during poor weather or limited sunlight. With support for sustainable energy goals and reduced maintenance demands, EFOY fuel cells are backed by expert engineering support to ensure reliable, long-term performance.

Inverters play a vital role in telco power systems by converting DC backup power into AC to keep essential equipment, like servers and cooling systems running during outages. High-efficiency models, such as those from CE+T, offer up to 96% conversion efficiency with zero-millisecond transfer times, ensuring uninterrupted power and reduced downtime. These solutions also help lower energy costs and improve sustainability, with tailored options available to meet the specific demands of both small and large telecom installations.

Enclosures and thermal management are critical for protecting telecommunications equipment from dust, moisture, and extreme temperatures, particularly in New Zealand’s varied and demanding environments. Without proper protection, overheating and environmental exposure can lead to equipment failure and costly downtime.

Purpose-built enclosures and advanced cooling systems help maintain optimal operating conditions, reduce energy consumption, and extend equipment lifespan. These solutions ensure reliable performance and uptime, even in remote or challenging locations.

Advanced remote monitoring and control solutions are essential for maximising uptime in telecommunications networks. By enabling real-time visibility into power usage and equipment health, these systems help prevent outages, reduce operational costs, and minimise on-site maintenance. Efficient monitoring also protects equipment from overuse and environmental stress, extending its lifespan and lowering capital expenditure over time.

DC-DC converters play a key role in telecommunications by adjusting voltage levels within DC power systems to meet the needs of specific equipment, including sensitive devices requiring isolation or regulated outputs. They are also widely used in vehicles and trains to power onboard radio and communications systems. A range of formats, including 19" rackmount, DIN-mount, and models designed for mobile and rail environments ensures compatibility across diverse telcom applications.
