Solar panel charge regulator controller VarioString

for batteryboat

The VarioString responds to the toughest requirements in efficiency in solar installations. It also reduces the system costs by accepting PV strings up to 600 or 900Vdc. This allows for a more simple installation and reduces the installation time and material costs: reduction in cable cross-section and length, absence of junction box and string fuses. The two isolated MPPT inputs allow for the integration of PV strings with different electrical characteristics and orientations. The reinforced isolation between the PV modules and the battery allows for any combination of grounding schemes and an optimised system security.
