Our UPS and battery installation service is designed to ensure a smooth, safe, and efficient setup of power systems for commercial, industrial, or residential use. We begin with an on-site assessment to understand your infrastructure, load requirements, and site conditions. Based on these inputs, we recommend the most suitable UPS model and battery configuration.
Our experienced engineers handle every aspect of the installation process, from equipment positioning and cabling to system integration with your existing power infrastructure. Special attention is paid to safety compliance and environmental factors such as ventilation, humidity, and electrical noise. Upon completion, we run full system diagnostics and trial operations to ensure everything functions correctly.
In addition to the installation, we provide the end-user with a basic system overview and operational guidelines. Our goal is not only to install the equipment but to ensure that your team understands its operation and maintenance needs from day one.

We believe knowledge is key to maximizing the performance and longevity of UPS systems. Our technical training programs are tailored to your team’s level of expertise and the complexity of your equipment. Whether you're operating a single-phase UPS for office use or a complex three-phase system for data centers, we provide you with the necessary knowledge to operate and maintain it effectively.
Training sessions include operational guidance, routine maintenance procedures, troubleshooting tips, battery care, and safety protocols. These can be conducted on-site, at our training center, or virtually, depending on your needs. We also provide training documentation and access to support materials post-training.
Our aim is to empower your staff to confidently manage the power systems and reduce reliance on emergency service calls.

Preventive maintenance is crucial for ensuring long-term system reliability and avoiding unexpected failures. Our UPS and battery maintenance service is structured around regular inspections, component testing, software updates, and performance optimization.
During scheduled visits, our technicians check for battery wear, capacitor health, fan functionality, dust buildup, firmware issues, and signs of component fatigue. Reports are generated after each visit detailing system health and suggested corrective actions if needed.
This service not only extends the life of your UPS and batteries but also ensures compliance with warranty conditions and reduces the likelihood of critical system downtimes.

When your UPS system malfunctions, immediate action is essential to minimize disruption. Our repair service is designed to provide fast, expert solutions with minimal impact on your operations. Whether your issue is due to internal component failure, battery breakdown, inverter faults, or software bugs, our technicians are equipped to handle it.
We begin with a detailed diagnosis using advanced testing tools to identify the root cause. Minor issues can often be resolved on-site, while major repairs may be handled at our service center. We use original spare parts and adhere to manufacturer repair protocols to ensure system integrity.
Additionally, we offer emergency repairs with priority response in critical environments like hospitals or data centers.

Choosing the right UPS capacity and battery backup time is essential to protect your equipment without overspending. Our calculation service involves a detailed analysis of your critical loads, runtime expectations, and site constraints.
We assess power ratings, startup currents, load profiles, and redundancy requirements. Based on this data, we recommend an optimal UPS model and battery configuration that balance performance, cost, and scalability.
This service is especially useful for new installations, expansions, or upgrades and helps in proper budgeting and long-term energy planning.

At Zener Engineering, we see customer feedback as a vital tool for growth and improvement. Every interaction with our after-sales team is an opportunity to learn and evolve.
We gather feedback through service reports, follow-up calls, and surveys to assess satisfaction and areas for improvement. Common feedback themes are analyzed regularly by our quality assurance team and translated into actionable changes in our processes.
We also maintain a feedback loop with our product development and commercial departments to relay recurring technical concerns and customer expectations, ensuring future product designs and service strategies align better with real-world needs.

Routine maintenance is the backbone of a reliable power infrastructure. Our scheduled maintenance plans are customizable based on the criticality of your application, environmental conditions, and manufacturer recommendations.
Services include visual inspections, thermal imaging, performance logging, battery impedance tests, firmware upgrades, and report generation. Each maintenance cycle helps track aging components, preempt failures, and keep the system within warranty parameters.
These proactive visits minimize unplanned downtimes, maintain peak efficiency, and extend the lifespan of your power protection system.

Unpredictable power disruptions or equipment failures can bring operations to a halt. Our emergency service is available 24/7 to ensure minimal downtime and rapid resolution.
We have mobile service units and regional technicians ready to be dispatched immediately upon notification. Within Tehran, our response time is under 2 hours; for other cities, we guarantee service within 24 hours in emergencies.
Our team carries essential spare parts and diagnostic tools to perform fast on-site fixes whenever possible. When temporary solutions are not feasible, we provide rental units or backup solutions until full repairs are completed.

For businesses requiring temporary power backup — whether for events, system upgrades, or emergencies — our UPS rental service offers a convenient and cost-effective solution.
We provide a range of rental units suitable for both small-scale and large-scale applications. Services include delivery, installation, testing, and removal. Rental durations are flexible — from a few days to several months — and include full technical support throughout the rental period.
This is ideal for customers facing unexpected UPS failure, waiting for spare parts, or undergoing short-term high-load operations.

Relocating a UPS and battery system requires careful planning, proper disassembly, and secure transport. Our relocation service ensures your power systems are moved professionally with zero damage and minimum downtime.
We perform pre-move assessments to evaluate disconnection strategies and safety protocols. During the move, systems are packed securely, transported using vibration-protected methods, and reinstalled at the new site with all functional tests performed.
This service is ideal for businesses moving offices, upgrading facilities, or consolidating IT infrastructure.

Batteries are the most vulnerable part of any UPS system, and timely replacement is essential for ensuring continued protection. Our battery replacement service includes inspection, compatibility verification, safe removal, and certified disposal.
We install new batteries from leading manufacturers and ensure proper calibration with the existing UPS system. Battery logs are updated, and clients receive maintenance tips for extending battery life.
We also offer group replacements for large battery banks and recycling options to support sustainability.

Capacitors and cooling fans are vital to your UPS's performance and are typically subject to wear after 5-7 years of use. Our replacement service ensures these components are changed before failure occurs, preventing costly damage and system downtime.
We conduct pre-replacement evaluations to identify signs of aging or stress, then replace capacitors and fans using OEM parts that meet or exceed the original specs. Thermal management, voltage regulation, and internal airflow are all restored to optimal levels.
This service significantly extends the operational life of your UPS and ensures better system reliability.
