PicoCell™ 3500

 

 

Off Grid Solar Pump Controller

 

 

SunTech offers you the ability to upgrade a hard starting DOL single- or three-phase motor system to a soft start Variable Frequency Drive Technology running on solar power. The PicoCell 3500 universal controller can power motors, pumps, compressors or other inductive loads regardless of whether it is 50HZ or 60HZ, 120Vac or 240Vac. Now you can retrofit single-phase 2HP – and up to three-phase 3HP – pumps, fans and compressor motors. Designed for remote off-grid installations, the weather proof all aluminum chassis/heat sink is IP65 rated for harsh outdoor environments and can operate in high temperatures, humidity and corrosive environments.

SunTech Drive engineers have improved on the functions and features of traditional solar controllers to run inductive motor loads by replacing old electromagnetic designs with high voltage silicon components intelligently controlled by our patented adaptive firmware. The PicoCell 3500 integrates the functions of an inverter, VFD, MPPT controller, phase initiator and  voltage boost with automatic control.

PRODUCT HIGHLIGHTS:
