Medha’s 60 kW string inverters are designed to maximize energy harvest and ensure high reliability for small—to medium-scale solar installations. They offer advanced features and robust performance, making them an excellent choice for various solar applications.

High Return on Investment

Medha’s 60 kW inverters provide high conversion efficiency and feature six independent Maximum Power Point Tracking (MPPT) inputs. The high PV input voltage reduces losses on the DC wiring, while low startup and stop voltages maximize energy harvest. Intelligent firmware and architecture ensure continuous operation even with excessive panels to ground capacitance.

Easy and Safe Service

Firmware upgrades are simple via Ethernet with auto/manual options. Both DC and AC surge protection with included monitoring protect the inverter from lightning threats, ensuring safe and reliable operation.

Remote Monitoring and Control

The inverter’s easy interface to the Internet allows quick access to all parameters and fault monitoring, resulting in lower operation and maintenance costs.
