This new addition PVS family, with 3 independent MPPT and power ra-
tings of up to 60 kW (480 V version), has been designed with the objec-
tive to maximize the ROI in large systems with all the advantages of a
decentralized configuration for both rooftop and ground-mounted instal-
lations.
Design flexibility
The internal circuitry is with double stage conversion and therefore consists of:
- DC/DC input converter (booster)
- DC-AC output inverter
The DC-DC converter and the DC-AC inverter both work at a high
switching frequency and are therefore small and relatively light.
Each input converter is dedicated to an array with a maximum power
point tracking (MPPT) function in order to maximize the exportation of
energy from the photovoltaic generator.
This inverter version is of the type without transformer, that is without gal-
vanic isolation between the input and the output. This allows ultimately
an increase in conversion efficiency.
The operation and the protection management of the inverter is control-
led by two independent DSPs (Digital Signal Processors) and a central
microprocessor.
The connection to the distribution grid is thus kept under control by two
independent computers, in full compliance with the electric field norms
both for power supply to the systems as well as security.
In doing all this, we guarantee optimal operation of the whole assembly
and a high performance in all irradiation conditions and always ensuring
full compliance with the relevant directives, standards and regulations.
Embedded multi communication interfaces (WLAN, Ethernet, RS485)
combined with a Sunspec compliant Modbus protocol (RTU/TCP) allow
the inverter to be easily integrated with any third party monitoring and
control systems.
