PRAG offers you 8.0kVA – 48V Inverter – Studer Xtender XTH 8000 – 48 with its seemingly limitless programmable functions, the XTH offers unequaled flexibility compared to other products on the market.
The inverter/charger has a continuous power rating of 7kVA up to an ambient temperature of 40°C. In addition, it has a 30 minute power rating of 8kVA, and can deliver 21kVA for up to 5 seconds! Thanks to this very high surge power capacity, it can supply without worries loads with a high start-up current.
The battery charge current can be adjusted between 0 and 120Adc. The factory default settings include a battery charge curve best suited for lead acid batteries with gelled electrolyte (GEL). This battery charge curve can be easily adapted to other types of batteries including OPzS, NiFe, Lithium and Redox Flow, to name but a few.
The transfer system is active when an AC power source (generator, public grid, shore power…) is available at the AC input of the Xtender. The transition between inverter and transfer mode is achieved without any power cut and allows up to 50Aac of current to pass through to the loads. Similarly, the transition between transfer and inverter mode is extremely fast (max 15ms), which makes the Xtender suitable for many UPS (uninterruptable power supply) applications.
The Smart-Boost function allows the Xtender to assist the AC source via the inverter function. This way, the currents from both sources (AC-in and inverter) are combined to deliver the energy required by big loads if the loads are more than the AC source can supply.
The injection function allows the Xtender to send energy to the grid. This function is especially useful in energy storage systems where either the excess energy is injected to the grid, or a specific current is injected at a specific time of the day.
The Xtender has two auxiliary contacts, configured by default for the automatic start of a generator and the alarm function.
In addition, the Xtender can be equipped with a remote entry, which can be used to change functions or control the system externally.
Monitoring and control onsite or remotely is possible with the RCC-02/03 remote control or with the LAN, GSM or SMS interfaces. Detailed information on all Xtender accessories can be found on the corresponding section of the website.
The Xtender communication bus is shared with the MPPT solar charge controllers of the VarioTrack and VarioString series. Inverters and charge controllers are synchronized to ensure an optimum charge of the battery and use of available energy.
