Product Description

The Sunsynk Loadshedder 2 is a compact integrated solar energy system that combines a hybrid inverter, lithium battery, and MPPT charge controller into a single unit. It is designed for simple installation with built-in connection ports for load, grid, current transformer (CT), and Wi-Fi data logging, allowing hassle-free setup and monitoring. The hybrid inverter intelligently manages solar PV input, battery charging and discharging, grid power exchange, and essential load supply during outages or load shedding events. The system supports expansion through parallel connection with additional units or compatibility with external SunSynk batteries to increase storage capacity. It also integrates with the Sunsynk Connect platform for full system control and visibility.
