MS-RE Solar Inverter
The MS-RE Solar Inverter range, is designed for locations having unreliable or limited access to electricity, to provide a reliable and aordable energy
access solution. It is designed to supply continuous energy from solar and grid based on availability.
The Inverter is customized to prioritize solar energy over grid supply. This helps to extract maximum energy from solar making it a sustainable energy
access solution for homes, micro enterprises, health centers, schools, and oces.
