Benefits with M88H

All-in-one Design: String fuses, surge protection devices, DC switches are all integrated in.

Multi-application: Design for commercial & utility applications.

Saving on Space Cost: Can be mounted on the foothold of the PV panels, no house or container is requiredfor inverter installation.

2 MPP Trackers: 2 MPP trackers provide more flexibility for PV arrays configuration and bumpyground area to maximize yield.

Outstanding performanceM88H have excellent efficiency performance, peak 98.8% and Euro 98.5%.

Easy Installation: Ergonomic grip design provides easyinstallation or removal by the installer.For additional flexibility, eye bolts areprovided to allow for lifting using crane.

String monitoring function: The string monitoring function can precisely record real-time c urrent value up to18 strings via RS-485 interface.
