Stder Innotec VT-65 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 possible a solar module with a voltage of, for example, to connect 57V to a 12V battery or to connect two 12V modules in series to a 12V 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)
Because the solar modules may have a higher voltage than the battery, significantly smaller cable cross-sections can be used, which is a big cost savings, particularly for long lines. The VarioTrackDesigner MPPT controller of Studer Innotec has a very high efficiency of up to 98%.
How it is used to for Studer, the controller may has some more than the competitors. 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 more favorable (larger) solar modules are used
- Reduced installation costs (cable)
- Fully programmable
- parallel connection
- Built-in LED display, display connectable
