How does a hybrid PV inverter work?

This hybrid PV inverter can provide power to connected loads by utilizing PV power, utility power and battery power. Depending on different power situations, this hybrid inverter is designed to generate continuous power from PV solar modules (solar panels), battery, and the utility.

How do I connect my inverter to a photovoltaic panel?

The electrical power and signals wiring from the inverter to the AC Grid and to the photovoltaic panel are connected through the Switch Box as described in Fig.11 SB-01 – "DC Switch Box Layout" –using the access windows in pos “A” for the power cables and the windows in pos “D” for the signal cables.

How does a photovoltaic inverter work?

After completing a set of electronics and safety auto-test routines, the inverter starts the grid connection process. As mentioned above, during this stage Aurora automatically tracks and analyzes the maximum power point (MPPT) of the photovoltaic field. Aurora indicates that insulation resistance was found to be too low.

How many inverters can a photovoltaic system handle?

The AURORA is capable of handling 2 separate arrays. If the output of photovoltaic system exceeds the capacity of a single inverter, additional Aurora inverters can be added to the system; each inverter will be connected to an adequate section of the photovoltaic field on the DC side and to the grid on the AC side.

Can a photovoltaic array be connected to a single input channel?

If the system has one single photovoltaic array and the current from it is less than 16Adc for the PVI-4.2 model or 10Adc for the PVI-3.0/3.6 models, and the power of the array is below the limit for the single channel (see table in 8.1 paragaph), then the array can be connected to one single input channel (IN1).

How do I sizing a photovoltaic system?

The system configurator available on Power-One's web site at may help in sizing a photovoltaic system. When more than one inverter is used, remote monitoring can be implemented through a sophisticated communication system based on an RS-485 serial interface, with a USB port to facilitate access during installation.
