Introduction 
 

 

Hybrid Power System

 

 

This is a multifunctional off grid solar inverter, integrated with a MPPT solar charge controller, a high 
frequency pure sine wave inverter and a UPS function module in one machine, which is perfect for off grid 
backup power and self-consumption applications. The transformerless design provides reliable power 
conversion in compact size.  

The whole system also need other devices to achieve complete running such as PV modules, generator, or 
utility grid. Please consult with your system integrator for other possible system architectures depending on 
your requirements. The WiFi / GPRS module is a plug-and-play monitoring device to be installed on the 
inverter. With this device, users can monitor the status of the PV system from the mobile phone or from the 
website anytime anywhere.
