Stder Innotec VS-70 MPPT
The MPPT charge controller of Studer makes it 10-30% more power from the connected solar modules extract. By MAXIMUM POWER POINT TRACKING (MPPT), the solar module is always operated at the maximum power and not be forced to the battery voltage.
It is thus possible, a string of solar modules with a voltage of, for example, to connect 430 V to a 48V battery.
In the winter when the power supply with solar technology is critical to have the solar modules the highest voltage and thus the energy gain with an MPPT controller greatest. In addition, the efficiency at low battery voltage additionally increases, which may result in an energy gain of up to 70%. (Winter and deep battery voltage)
The fact that the solar panels can have a higher voltage than the battery, significantly smaller cable cross-sections can be used what especially with long lines, a large cost savings is. The VarioTrackDesigner MPPT controller of Studer Innotec has a very high efficiency of up to 98%.
How it is accustomed at Studer can to provide the regulator much more than the competitors has , So the controller is fully programmable, it can be up to 15 controllers are connected in parallel, the unit is equipped with a very robust, splash-proof aluminum housing (IP54), and can in addition to the built-in LED display, a display can be connected.
- An average of 10 - 30% more yield
- Up to 70% greater yield at low battery voltage in winter
- It can favorable (larger) solar modules are used
- less installation costs (cable)
- Fully programmable
- Parallel connection
- Built-in LED display, display connectable
