Energy conversion to alternating current Basic functions for a grid-connected inverter All inverters for grid-connected systems have at least the following core functions: Transformation / DC-AC Conversion To transform the direct current produced by the photovoltaic generator into alternate current and adapt it to the voltage level of the electrical grid for input into the grid.
Energy conversion to alternating current Transformation / DC-AC Conversion There are two types of static converters used in the field of photovoltaics: Grid-switching inverter Industrially-derived, they are based on the use of thyristors or GTOs and traditionally are used to pilot electric motors, including those in the traction sector.
Energy conversion to alternating current Automatic adjustment of the working point by means of an MPPT algorithm What is it used for? To maximize the energy harvested from the photovoltaic field, even in conditions of radiation variables How does it work? The inverter find the optimum working point in real time in such a way that the modules always operate in their maximum power point (Maximum Power Point Tracking).
The static conversion system of energy Type of string inverter: dual stage insulated with high-frequency transformer conversion + DC / DC stage Galvanic. Isol.
Energy conversion to alternating current Characteristics of inverters "isolated by a high-frequency transformer" Advantages and limitations of high frequency isolation technology Advantages: Downward extension of working input voltage range to be able to operate below the peak voltage of the grid (intrinsic limit of transformerless single stage of the technology).
Energy conversion to alternating current String inverter topology: “"Transformerless with single-stage conversion"” + EMI/EMC Filter Inverter Grid filter Grid Interface Relay DC + AC GFCI EMI/EMC Filter varistors AC grid L DC Input N _ varistors "H" Bridge with IGBT IR uP (supervisor) Transformerless Single-Stage: Minimizing losses and higher conversion efficiency Lighter weight and more compact size compared to traditional inverters with 50Hz.
Energy conversion to alternating current Characteristics of transformerless single-stage conversion inverters" The "pros" and some limitations of single-stage technology: Pros: High peak efficiency, combined with relative simplicity of the circuitry. Solution very effective if the input voltage range is rather small and particularly complex panels configurations are not required. Limitations: Range of input voltages limited and shifted "upward".
The static conversion system of energy Multi-string inverter type: dual-stage transformerless conversion Transformerless with "dual-stage" type: Two steps of conversion at high frequency in cascade.
Energy conversion to alternating current Characteristics of “transformerless dual-stage conversion" inverters Advantages and limitations of "dual-stage" transformerless architecture Advantages: Input voltage range extremely wide Very flat efficiency curves, with performance rather insensitive to operating conditions and input voltage/output current. The inverter always operates at the optimal voltage level to maximize efficiency allowed by the stabilizing action of the DC/DC input converters.
Topology 1-Phase string inverters Transformerless Technology Minimizing losses and increasing conversion efficiency. Other adventages of “Dual Stage” topology: M • The inverter always operates in maximal efficiency region • Extrem wide input voltage range combined with flat efficiency curve Array can be split in 2 independent subarrays each with stand-alone maximum power point tracking.
Topology 3-Phase string inverters • True 3-phase bridge topology for DC/AC output converter (not 3 x single-phase inverters in one package!!) • Each MPPT input includes standard MultiContact® MC4 connection for 3 strings • Available with optional integrated DC switch and fused inputs, to complete the DC protection system for large plants without extra-costs or external components 12A max. per connection pair! Allowed increase up to 20A .

Communication: RS485 RS485 signals are floating and each signal is transmitted over a + line and a - line. RS485 receiver compares the voltage difference between both lines, instead of the absolute voltage level on a signal line. With RS485 there is no any common zero as a signal reference. Several volts difference in the ground level of the RS485 transmitter and receiver does not cause any problems.
