Medha’s 30 kW string inverters are designed to deliver high efficiency and reliability for small to medium-scale solar installations. These inverters offer advanced features and robust performance, making them an excellent choice for various solar applications.

High Return on Investment

Medha’s 30 kW inverters provide high conversion efficiency and feature two 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

The inverter includes a touch-safe fuse holder for easy and protective fuse replacement. Firmware upgrades are simple via Ethernet with auto/manual options. Both DC and AC surge protection devices (SPD) 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.
