At the heart of small-scale, grid-tied energy-harvesting systems the inverter delivers excess power to the grid during periods of high energy from ambient sources. In designing grid-tied inverters, engineers need to ensure that this excess power is tightly synchronized to the grid, typically through the use of sophisticated phase-locked loop (PLL) implementations. To meet varied synchronization challenges, engineers can create effective PLL grid-synchronization algorithms by leveraging the performance and functionality of highly-integrated MCUs and related devices from manufacturers including Analog Devices, Cypress Semiconductor, Freescale Semiconductor, Infineon Technologies, IXYS, Littelfuse, Maxim Integrated, Microchip Technology, Microsemi, NXP Semiconductors, Renesas, STMicroelectronics, and Texas Instruments.

Connected to the utility power grid, small-scale residential energy-harvesting systems offer customers the opportunity to earn credit by passing excess generated power to the grid. At the heart of these systems, grid-tied inverters are responsible for delivering this excess power seamlessly, meeting specific requirements for power quality. Among these requirements, the need for tight synchronization with grid power is paramount.

When driving power to the grid, grid-tied inverters must provide a stable, sinusoidal AC waveform that matches grid voltage and frequency according to utility standards. Poor synchronization can lead to load imbalances, damage to connected equipment, instability in the grid, and even power outages in the grid itself.

In power-utility facilities, grid synchronization relies on control of the speed of massive turbines and generator motors used to generate power. In an energy-harvesting system, however, grid synchronization relies on control of the inverter’s full-bridge output stage used to produce the required AC waveform.

How to connect the sensor?

1.conect the RS485 cable of the AC power acquisition meter to the 485 port of the inverter.

2.Plug the connection terminal of the transmitted current sensor into the port of the collector "CT-IN" (no +-)

3.Connect the AC power supply port "AC-IN" of the collector to the same AC power supply for the load. After the connection, it will light up.

4.In the inverter LCD, enter the "battery grid connection", through the SET {Bat AutoLimit Grid}

5.Connect the inverter to AC power first, then connect the battery, the inverter will automatically output the same power as the power detected by the collector.Therefore, the inverter will not have excess electricity to be sent to the grid (ie: automatic limiter function)

6.One acquisition meter can connect 10 unit grid tie inverter
