Grid Connection System

Product catalog summary

Overview of System Components and Configurations

The document outlines various configurations and components involved in power systems integrating grid-tied inverters, backup systems, and voltage limiters. It highlights the interaction between load, meter, grid-tie inverters, backup systems, and voltage limiters within hybrid and grid-connected systems.

Main Sections and Components

Load: The electrical demand or consumption point in the system.
Meter: Device measuring electrical parameters, likely for monitoring or billing.
Grid-Tie Inverter: Converts DC power to AC and synchronizes with the utility grid, enabling power export or import.
Backup System: Provides power during grid outages, ensuring continuity of supply.
Voltage Limiter: Controls voltage levels to protect system components and maintain stability.
Hybrid System: Combines grid-tie inverter and backup system functionalities, optionally including voltage limiting features.
Grid Connected System: Standard configuration where the system is connected to the utility grid, optionally with backup load and voltage limiting.

System Configurations

The document repeats two primary system types:

Hybrid System: Incorporates grid-tie inverter, backup system, and voltage limiter, with optional backup load.
Grid Connected System: Includes grid-tie inverter and voltage limiter, with optional backup load, but primarily relies on the grid connection.

Key Points and Recommendations

Voltage limiters are critical components in both hybrid and grid-connected systems to ensure voltage stability and protect equipment.
Backup systems and loads are optional but recommended for enhanced reliability during grid outages.
Metering is essential for monitoring system performance and energy flow.
System design should consider the integration of AC and DC components, especially in hybrid configurations.

Summary

This document provides a high-level schematic overview of power system configurations involving grid-tie inverters, backup systems, and voltage limiters. It emphasizes modularity and optional backup capabilities to enhance system resilience and stability.

Lo Eveready Diversifie! Products (Ptyl Ltd www. ke=>1relwlnd. co. z& Small wind energy Systems may be connect驩e! to the electricity distribution System, the grid. The Kestrel Grid-connected System can reduce consumption of utility-supplied electricity for lighting, appliances, and electric heat. When the turbine cannot deliver the amount of energy needed, the utility makes up the diffrence. This is done so that the renewable energy Systems, although capable of powering houses and small businesses without any connection to the electricity grid, gains advantages by synchronising with the grid. A grid-connected System allows you to power your home or business with renewable energy during those periods when the wind is available. Any excess electricity you produce is fed back into the grid. When renewable resources are unavailable, electricity from the grid supplies the energy need, thus eliminating the expense of electricity storage devices like batteries and increasing your energy independence. Active3 fcleclricity Meanagemprit P^rSOncal Powpr (jrppn Ciuidc3ncea In order to connect in parallel to the existing supply a sp鯩cial inverter (called a Grid Tie Inverteri is used to synchronise the varying voltage from the Kestrel Wind Turbine to the stable grid supply. The Grid Tie Inverter is individually programme! to optimise the amount of power exported to the grid using complex algorithms as well as ensuring network safety by disconnecting if the grid fails or becomes unstable. F'-IOO' Thse Systems have recommended maintenance guides and a service team is available to deal with any concerns. Kestrel Grid-connected Solution is available in e30O' (1kW) and eAQO騯 (3kW) 250Vdc System Also available with a battery back-up. Due to lgislation, the Grid Tie Inverter may not operate during a grid failure, so in order to maintain the power supply when the grid fails, a battery back-up is required. In an emergency the back-up System instantly changes the supply from grid to the battery bank and supplies electricity when the utility company fails.
