Studer VarioString VS-70 Charge controller MPPT 48 V 70 A

With the MPPT charge controller Vario track can be achieved the highest performance from each solar system and the batteries during recharging charged. The solar charging controller works with a sophisticated algorithm continuously the maximum working point (MPPT) searches and thereby the battery optimally with the existing solar energy.
Due to the high PV input voltage range, the costs significantly reduced on the PV page Despite the conversion of the high PV voltage down to the battery voltage of 48 V, and the between PV and the battery insulated MPPT controller reaches the vario string has a degree of efficiency of 98%. Designed for any solar systems offers the vario string connected with the xtender is the perfect combination. Thanks to the communication between the two devices is a synchronized charging cycle.

In the following anwendugnsgebieten can be the Vario track:

Hybrid System: Larger independent friendliness and flexibility with inverter/Battery Charger Xtender
This system offers a great versatility and a high level of independence in the choice of different power sources. The consumers are either directly from the AC power source via the switching relays, or from the battery via the inverter is supplied. If the generator is running, the batteries are charged via the battery charger. With a xtender and its function Smart Boost, the size of the generator optimized it. Thanks to its comprehensive and open programmability can be adapted to the xtender for each application. The performance range of the inverter ranges from 0.5 to 72 kVA, one-and three-phase.

Electrification of settlements
The energy supply for professional applications such as hotels, clinics, hospitals, schools, etc., autonomous systems of the highest reliability, modularity and efficiency. The construction of a public micro-grid, the same qualities.
The device family of the xtender, VARIO track and Vario string form thanks to its exceptional flexibility the ideal building blocks for the realization of such a electric micro-grid. By customised combine these devices, it is possible systems from a few kVA to over 72 kVA to realize, which results in an enormous diversity of applications opens up.
The different communication options (GSM, Web, SMS) allow by permanent access to distance the system monitoring and operation. The enormous flexibility of the xtender, the heart of a mini network, makes it possible to realize a tailor-made system for each application. Thanks to its built-in frequency control, the xtender also ac power sources (supply inverter) to control which can be integrated into the mini power, which gives you free choice can regarding the energy coupling (DC and/or AC).

Solar/battery charger with inverter supply for a BTS xtender
A hybrid solution can significantly reduce the diesel consumption and significantly improve the efficiency of the generator. The excess solar energy can be used with the help of the DC-AC converter for other applications. Moreover, the monitoring of the integrated battery and allows the inverter output in function of the battery voltage must be switched off. Reduction of operating costs and longer life.
