Havells 20 kw Solar On-Grid Inverter

Havells 20 kW Solar On-Grid Inverter: Detailed Description

The Havells 20 kW On-Grid Solar Inverter is a robust, high-capacity, three-phase, transformerless string inverter primarily intended for commercial, industrial, and large institutional solar projects. It is engineered to deliver maximum energy harvest and ensure seamless compliance with utility grid standards.

Power and Performance

• Rated Power: The inverter provides 20,000 W (20 kW) of continuous AC power output.

• Phase: It operates on a Three-Phase system, standard for high-power commercial installations.

• Maximum Efficiency: Achieves high conversion efficiency, typically up to 98.6%, minimizing energy loss during the DC-to-AC conversion process.

• MPPT Technology: Equipped with Dual Maximum Power Point Trackers (MPPTs). This is crucial for optimizing power generation, especially in complex roof layouts or when facing partial shading, as each tracker manages independent strings of solar panels.

• DC Overloading: The design often supports a high DC-to-AC ratio, allowing connection of a larger solar array (e.g., up to 30 kWp) to the 20 kW inverter to ensure maximum output during non-peak sun conditions.

Input and Safety Features

• Maximum DC Input Voltage: Supports a high DC input, often up to 1100 V, which allows for longer PV strings and reduces overall wiring costs and system complexity.

• Wide MPPT Range: It operates across a wide DC voltage range (e.g., 140 V to 1000 V), enabling the system to start generating power early in the morning and continue late in the afternoon.

• Surge Protection: Features inbuilt Type II Surge Protection Devices (SPDs) on both the DC (solar panel) and AC (grid) sides to safeguard the inverter against voltage spikes and lightning-induced surges.

• Grid Protection: Includes critical safety functions such as Anti-Islanding Protection, DC Reverse Polarity Protection, and Ground Fault Monitoring, ensuring safe and compliant grid connection.

Monitoring and Installation

• Environmental Protection: It has an IP65 ingress protection rating, making it highly resistant to dust and water jets, and suitable for reliable outdoor installation.

• Cooling: Typically utilizes Natural Cooling for quiet operation and increased longevity.

• Remote Monitoring: Standard communication via RS485 and optional Wi-Fi or GPRS data loggers allow users to monitor performance data in real-time via web portals or mobile applications.

• Data Logging: Often includes internal data storage capacity for years of operation logs.

• Zero Export Control: The inverter can be configured with an optional Anti-Reverse Power Controller (ARPC) to meet local regulations that may require limiting or preventing the export of surplus solar electricity to the grid.
