TSS beats the odds

TSS beats the odds

In 12 weeks time, despite shortages in the market, TSS managed to supply 4 orders counting a total of 76 systems, consisting of 12 different system types.

In order to do so we had to pass 9 heat soak tests, 17 FAT’s and a staggering 76 internal inspections!

We would like to thank our suppliers Mansveld, VHE, ABB, Rittal, Eternity, Unique Electricway TMI and Sonnenkraft/Kioto Solar for making this possible.

Old school batterij technologie in offgrid energiesystemen

De uitrol van zonnepanelen draait in coronatijd volop door, zowel in de residentiële als de zakelijke markt. Het gebruik van batterijen komt sterk op, in Vlaanderen in de vorm van de thuisbatterij en in Nederland in die van grootschalige opslagsystemen. Dit is echter niet de wereld van TSS4U. Het levert offgrid solar en solar hybride-systemen, met name voor offshore en onshore olie- en gasinstallaties. Die markt kent zijn eigen wetten, zowel wat betreft conjunctuur als technologische vereisten.

TSS4U heeft zijn roots in het voormalige Shell Solar in Helmond. Chief operational officer en mede-eigenaar Jan-Willem Linsen werkte er eerst aan netgekoppelde, daarna aan autonome industriële zonne-energiesystemen. Na de overname van Siemens Solar in 2001 zette het bedrijf een punt achter de productie van zonnepanelen in Nederland.
2 jaar later werden de offgrid-activiteiten overgeheveld naar München. Linsen en enkele van zijn collega’s besloten uit te stappen en richtten TSS4U op.

CO2 savings

With the TSS infinitum control box and the TSS infinitum TCO software tool various diesel hybrid and solar only solutions can be provided. In below table we show the various cost and CO2 reductions you can achieve.

The TCO calculation TSS provide is taking into account the cost for maintenance and fuel. Transport of diesel and maintenance crew is not taking into account as this is depending on the location where the system will be installed. Each location requires a different solution resulting in a project specific TCO as shown right side.

Revitalize your Solar Energy System

Revitalize your Solar Energy System

In the past 30 years many large Oil & Gas companies started an off-grid solar department providing their own off-grid Solar System Solutions including their in-house developed charge control equipment. Many solar systems are now in use as the main energy supplier for vital equipment like Telecom, RTU, Wellhead control, valves, etc. Failure of the energy supply will result in high operational cost.


At TSS, we have seen many companies like Shell Solar, BP Solar, Total Energy/Tenesol stopping their off-grid solar activities resulting in clients not being able to maintain their current install base and to get spare parts or technical support for their Solar Power Systems. This has resulted in high downtime and high operation cost for these clients. TSS has been requested by many clients to help them in providing System Health Checks and spare parts for those systems for more than 10 years.


During the System Health Check our engineers provide you a report on the status of your system and which (preventive) maintenance should be carried out in order to revitalize these systems.

In order to be able to help these clients TSS has developed tailor made solutions by providing compatible new charge controllers which could replace the existing control equipment without the need of revising the whole system and including the system specific metering and alarms. Due to this we could provide a solution to our clients to keep their solar system running for the next 10 years or more without the need for a high investment for purchasing a complete new solar power system.


We would be happy to provide a similar tailor made solution for your off-grid solar systems that are currently failing due to the lack of spare parts or technical support from the manufacturer.

TSS- Art of No Cooling

“TSS - Art of No Cooling”

TSS’ expertise is in the development of equipment that can be placed in very hot climatic conditions. The presence of electronic equipment in such hot conditions generally leads to the problem of overheating which can result in inefficient functioning or even a complete failure of the system.


To tackle and alleviate the hitches and inefficiencies that arise as a result of heat, engineers generally employ different cooling systems for forcing a good thermal management. This is normally achieved by the use of fans which don’t have a long lifetime expectancy.

TSS Engineers’ Philosophy: Bottom Up Approach

Innovative design combined with the right selection of components make sure our electronic equipment is highly energy efficient and as a result have only little heat dissipation and don’t require forced cooling by fans.

Furthermore, our specially designed electronic components have in-built heat spreading capabilities which help to spread the heat from hotspots by natural convection within the enclosure.


These intrinsically cooled components ensure that the control equipment inside enclosures are heated up only in a controlled manner up to a maximum of 85°C! Thus, redundancy for temperature dependent failure in tropical environments are secured.


Such an efficiently designed control equipment can simply be used in the shade externally without any form of forced cooling (e.g. under solar modules). Even if the ambient temperature in the shade goes up to 55°C, the equipment continues to function perfectly without the need for any external cooling and without any de-rating.

Eindhoven companies collaborate on ’10 million-order’ for solar energy systems in the Middle East

Eindhoven companies are working together on record order for solar energy systems in the Middle East

EINDHOVEN – For its solar energy systems in oil fields, the Eindhoven-based company TSS4U is working on a record order of 10 million euros. Together with the regional suppliers VHE and Itsme, it realizes more than 150 systems in the desert of Abu Dhabi.


According to director Dop Brzesowsky of TSS4U, the turnover of many years is surpassed with the assignment for oil company Adnoc. The ‘Shell of the United Arab Emirates’ is going to tap new oil fields in the desert.

Biggest in ten years

In places like this where there is no electricity network, TSS4U supplies systems for controlling solar panels, storing solar energy in batteries and supplying power. “For larger assignments, it involves a value of 1.2 or sometimes 3 million euros. This of more than 10 million euros is the largest order in this industry in ten years”, says Brzesowsky.

He calls it ‘unique’ that a Dutch company has won the contract. “We often work with local contractors. We won the order because of the very high quality and reliability of our systems.”

Three companies with 35 employees

TSS4U does not produce itself. The company calls itself a system integrator. For the record order, it works together with suppliers VHE and Itsme. VHE assembles the cabinets with electronics in Veldhoven that control the energy systems. The Eindhoven wholesaler Itsme supplies switches and other electronic components. Around 35 employees from the three companies are involved in the assignment.

“As a team we have created something magical”, says the director of TSS4U. The order is also short preparation time. The production process had to be set up quickly. The companies also joined forces to finance the contract.

The first systems were delivered last month. The last deliveries are expected in the summer.

TSS4U awarded order of close to 10 million Euro

TSS secures the biggest order in the company’s history, worth close to 10 million Euro

TSS is awarded the largest order in the history of TSS. Spanish company Tecnicas Reunidas awarded a project worth close to 10 million Euro to TSS.


TSS will supply over 160 off-grid Solar Power Systems with a capacity ranging from 0.5kW up to 1.3kW, each with an autonomy period of 72 hours. These solar power systems will be commissioned in the Bu-Hasa Field in the United Arab Emirates.


The solar power systems will be used by the Abu Dhabi National Oil Company (ADNOC) for multiple purposes, such as powering telecom, RTU, Wellhead control panels, valves and pumps, including further development of the Bu-Hasa oil field and improvement of the overall production efficiency in the Bu-Hasa field.
