Havells 30 kw Solar On-Grid Inverter

Core Functionality and Application

The Havells 30 kW On-Grid Solar Inverter, a critical component in a solar photo-voltaic system, is engineered to convert the direct current (DC) generated by solar panels into grid-compliant three-phase alternating current (AC) electricity. As a grid-tie or grid-connected inverter, it works in tandem with the local utility grid, feeding excess solar power back into the system under a net-metering arrangement. This makes it an ideal solution for commercial buildings, factories, large office complexes, and industrial sites looking to significantly offset high electricity consumption.

Performance and Efficiency

This transformerless model is built for exceptional performance, boasting a maximum efficiency of up to 98.6%, placing it among the most efficient inverters in its class for maximum power harvesting. It utilizes a Dual MPPT design, which independently tracks the optimum operating point for two separate arrays or strings of solar panels, leading to higher overall energy generation, especially on roofs with different orientations or shade patterns. The unit operates with a wide DC input voltage range, providing flexibility for system design.

Safety and Durability

Safety is a priority, with the inverter including essential protection features such as an in-built DC switch for safe solar DC isolation, Anti-Islanding protection to safely shut down during a grid outage, and DC reverse polarity and overcurrent protection. The unit is housed in an enclosure with an IP65 degree of protection, ensuring it is highly resistant to dust and water ingress, making it suitable for outdoor installation in diverse environmental conditions. It is also BIS and IEC certified, confirming adherence to rigorous national and international quality and safety standards.

Monitoring and Connectivity

The inverter features a 4-inch LCD display that provides users with real-time generation data directly at the installation site. Furthermore, it supports modern remote monitoring capabilities via a built-in Wi-Fi or GPRS data logger and an RS485 communication port. This provides lifetime free web and mobile application monitoring, allowing owners and operators to track performance, diagnose issues, and analyze historical data remotely. For long-term data security and compliance, the inverter includes an SD card for up to 25 years of local data storage.
