studer XTM 3500-24



The Xtender range incorporates a range of powers and voltages: 1500W – 7000W in 12 / 24 / 48V options.

The Xtender series provides an incomparable freedom of use thanks to its many functions. In a basic application, it offers the utilities of inverter, battery charger, transfer system and assistance to the source.  These can be combined and controlled in a totally programmed way for an exceptional comfort and an optimal management of the energy available. Its programmable auxiliary contact allows as well the interconnection with existing systems or the implementation of extended functions.

By means of its own remote control this enables any software updates to be easily added thus making it an upgradeable product to which new functions may be added when they are available.

Through the implementation of several units, it is possible to create a 3-phase source or to set them in parallel, in order to increase the power available.  Up to 9 Xtender series inverters can then be combined together.

Key Features

  1. True sine wave voltage
  2. Dependable and soundless with any kind of load
  3. Outstanding overload capabilities
  4. Smart-Boost function for assistance to the source even with difficult loads
  5. Automatic reduction of peak loads (power shaving)
  6. Multi-stage programmable battery charger with PFC
  7. Stand-by level adjustable over a large range and from a very low threshold
  8. Ultra-fast transfer relay
  9. Control by digital signal processors (DSP)
  10. High efficiency


When the Xtender is connected to a generator or network, the latter directly supplies the consumers, and the Xtender works like a battery charger and backup device if necessary. The powerful battery charger has an exceptional high efficiency and power factor correction (PFC) close to 1. It guarantees excellent battery charging in all situations. The charge profile is freely configurable according to the type of battery used or the method of usage. The charge voltage is corrected depending on the temperature, thanks to the optional external sensor. The power of the charger is modulated in real time dependent according to the demand of the equipment connected at the Xtender output and the power of the energy source (network or generator). It can even temporarily backup the source if the consumer demand exceeds the source capacity.

The Xtender continuously monitors the source to which it is connected (network or generator) and disconnects itself immediately if the source is missing, disturbed or does not correspond to the quality criteria (voltage, frequency, etc.). It will then function in independent mode, thanks to the integrated inverter. This inverter, which has an extremely robust design, benefits from STUDER Innotec’s many years of experience and expertise in this area. It could supply any type of load without faults, enjoying reserves of additional power that is unmatched on the market. All your equipment will be perfectly provided with energy and protected from power outages in systems where energy supply is unpredictable (unreliable network) or voluntarily limited or interrupted, such as hybrid installations on remote sites or mobile installations.

The studer remote control and programme centre +2m cable our product code 07009DU05 must be used with all Xtender Inverters

The installation and commissioning of the Xtender Inverter must at all times be appointed to a qualified Solar PV Engineer or Electrician.  Select Solar have engineers who are experienced and fully qualified.   If you require further assistance or you have questions that you would like answers too, then please do not hesitate to contact us either by  email  or telephone 01793 752562 asking for Colin or Evren
