Online double-conversion UPS manufactured by KSTAR under our FORTE Green Power brand. Selection, supply, installation and service by one engineering team.
Operating since 2013, Project Energy Systems LLP supplies uninterruptible and backup power equipment under the PES POWER brand. We select UPS and batteries, supply equipment and provide installation and maintenance.
PES POWER
We select uninterruptible power systems for your facility, load and required runtime. Explore your application.
Equipment undergoes factory quality control and comes with a local warranty and PES POWER technical support.
Our Core Business
From compact single-phase units to modular data center systems. We calculate power, runtime and redundancy for each project.

Additional Solutions
A UPS protects the load only when the entire surrounding system is correctly assembled: batteries are sized for the required runtime, the generator takes over during a prolonged outage, and the room is kept at its operating temperature. PES POWER supplies all these elements and takes responsibility for their joint operation, so the customer does not have to coordinate several contractors.
We select the system components for each facility: calculate the load and starting currents, determine runtime, check UPS compatibility with the generator and prepare the site for installation. Our engineers commission and service all the equipment.
VARSAN · Türkiye
Single-phase stabilizers rated at 3.5–50 kVA and three-phase models rated at 10.5–1200 kVA with independent regulation of each phase.
Output voltage accuracy of ±1%, efficiency above 98% at full load, and a mechanical bypass.
A solution for sites with voltage dips and surges where battery runtime is not required.
FORTE Battery Systems
JS, JM, JH and JF series VRLA lead-acid batteries for UPS, telecommunications and backup power systems.
AGM, GEL, High Rate, Front Terminal and Lead Carbon technologies, as well as lithium solutions.
We calculate capacity and the number of strings for the required runtime, supply battery cabinets and racks, and replace batteries in UPS from any manufacturer.
Wokang Power · Silico Energy
Wokang Power and Silico diesel generators in open, enclosed and containerized configurations.
The generator takes over the load during a prolonged grid outage, while the UPS bridges the gap before startup and smooths the transition.
We select the rating for operation alongside the UPS, supply, install and commission the equipment.
Climate Control 24/7
Climate control systems for server rooms, UPS rooms and battery rooms.
A stable temperature extends the life of batteries and electronics and reduces the risk of emergency shutdowns.
We select cooling capacity based on equipment heat output and the redundancy scheme.
HPE · Dell Technologies
HPE and Dell servers and storage systems for corporate server rooms and data centers.
We supply computing equipment together with engineering infrastructure, so power, cooling and rack placement are sized for the actual IT load.
KSTAR · Turnkey Infrastructure
KSTAR cabinet, modular and containerized data centers: power, UPS, cooling, racks, monitoring and fire suppression in a single factory-built solution.
From a single rack to a containerized data center on an outdoor site.
Data Center Solutions
We select servers and storage systems to meet computing, fault tolerance and scalability requirements.
A data center failure is rarely caused by a single device. Problems more often arise at the interfaces between systems: the generator did not accept the UPS load, the air conditioner stopped with the grid supply, or batteries overheated and lost capacity.
That is why we design power, cooling and computing equipment as one system with a shared redundancy strategy.
Online double-conversion UPS rated from 1 to 1250 kVA. GPM3300 modular systems with 50, 100 and 125 kVA power modules allow capacity to grow with the load and provide N+1 redundancy.
We calculate capacity and the number of strings for the specified runtime and service life, taking room temperature into account.
A diesel generator supplies power during prolonged grid outages. We coordinate its rating with the UPS and cooling system.
Maintains server room and battery room temperature and humidity throughout the year, with redundancy.
HPE and Dell equipment for the customer's requirements.
One team installs, commissions and subsequently maintains the entire system.
This approach gives the customer one party responsible for the result. If something goes wrong, there is no need to determine whether it is a UPS, generator or cooling issue.
Tell us about your load, rack count and runtime requirements, and we will prepare a technical solution and quotation.
Discuss Your Data Center ProjectIndustry Solutions
We design systems around the load characteristics and the requirements of each site.
Modular UPS with N+1 redundancy, battery arrays, generators and precision cooling. Capacity grows without interrupting the load.
Uninterruptible power for operating theatres, intensive care units, CT and MRI, and laboratories. We account for medical equipment voltage-quality requirements and work at operating facilities without shutting down departments.
Protection for control systems, industrial automation and process lines where a shutdown means defective products and downtime. For challenging grids: FORTE EPOWER transformer-based UPS.
Power for lifts and escalators, emergency lighting, security systems, checkouts and server rooms.
Power for communications nodes and remote sites, outdoor cabinets with UPS, batteries and remote monitoring.
Engineering Approach
We take responsibility for equipment supply and correct operation of the complete power system.
We visit the facility or work from supplied information: load composition, starting currents, required runtime, room conditions, incoming supplies and cable routes.
We select the UPS, batteries, generator and cooling, prepare a specification, connection diagram and site requirements. The customer sees the scope and price before signing the contract.
We deliver, install and connect the equipment and test it under load, including transitions to batteries and generator power. We train the customer's personnel.
A 24-month UPS warranty and 12-month battery warranty. Scheduled maintenance, battery diagnostics using verified instruments, repairs and battery replacement.
