Efficient and user-friendly operation for solar pumping

Emotron VSR series drives offer reliable, cost-efficient and user-friendly operation. Soft start of pumps can avoid water hammer and improve lifetime of the system. The Emotron VSR series has been specially developed for solar water pumping. Built-in self adaptive high accuracy maximum power point tracking (MPPT) algorithm of VSR ensures maximum water flow output. The compatibility of VSR with ac as well as dc input gives user the flexibility to optimize the operation and improve reliability of operation. The function of dormant state at weak light, wake up at strong light, high water level dormant state, under-load pre- warning and other control protection functions can ensure normal operation of water pumps under changing operating conditions. Thanks to variety of specially designed features of VSR, it is truly the answer to your needs.
