ETS series Three

 

ETSseriesThree 

Detail

Modular MPPT solar controller

State-of-the-art solar maximum power point tracking technology, the utilization of solar panels can reach more than 99%

Wide PV input voltage range, more flexible solar panel selection and array configuration

MPPT solar controller modular system subsequent expansion provides great convenience

Three phase unbalanced load capability

Any one phase output independently drives the load, without affecting the other two phases;

Strong against impact current capability

Built-in low frequency isolation transformer, high impact resistance, can drive the motor, air conditioner with strong impact current

Support multiple equipments in parallel

Can be achieved through larger capacity power generation system by in parallel, while improving the reliability of system

Perfect protections

  1. Battery overcharge, over discharge protection and advanced battery management system extend battery life

The intelligent load graded protection strategy when battery power is low, giving priority protection for critical loads

Overload protection, short circuit protection to protect safe and reliable operation of the equipment and load
