SOLAR REGULATOR (Studer VT-80) 12/24V 80Ah
Form
A solar regulator connects the output of photovoltaic (PV) solar panels to a battery system. It adapts the voltage-current levels at the input to the battery voltage, thus protecting the battery from overloading. The built-in maximum power tracker (MPPT) ensures that the maximum solar power available is used to charge the battery.
Specifications:
- nominal system/battery voltage: 12, 24 or 48 V (configurable)
- max. solar power: 1250/2500/5000W (depend on system voltage)
- max. PV Voc voltage: 150 V (80 V Voc @12V system voltage)
- max. PV current: 75 A
- max. charging current: 80 A
- operational voltage range: 7-68/16-32/38-68 V (depend on system voltage)
- screw connectors for battery and PV, cable gland M6
- max. wire size: 35 mm² (screw terminal)
- temperature range: -20 to + 55 °C
- dimensions (HxWxD): 120 x 220 x 350 mm
- weight: 5.5 kg
Per piece.
Fit
The solar regulator fits with solar panel arrays of up to 150 V (Voc) and a PV current of up to 75 A.
The regulator can be used in systems with battery voltages of 12, 24 or 48 V. The charge current can be up to 80 A.
A wired communication interface (STUDER communication BUS) is available . This interface alows configuration and data transfer between conntected devices. Further communication interfaces can be added as optional modules, like the Remote Control RCC-02/-03 or a SD-card which can log operational data (via RCC/Xcom).
Function
The basic functions of a solar regulator are to control the input voltage and current from the PV solar panels in a way that batteries can be charged with their correct voltage and it ensures that batteries do not overload.
Additionally, the MPPT converter allows to regulate the input voltage at a level where PV solar panels produce the maximum power. This so-called Maximum Power Point (MPP) is adjusted dynamically according to instant solar radiation.
