SG600 Solar pump inverter--------------Software design
Control mode:VF for induction motor pumps,open loop vector control
for PMSM high speed pumps.
MPPT function:always performance MPPT for gain highest efficiency.
CVT:When sunlight is good,can select CVT control for excellent
stable frequency output.
Dry run function:When little water or no water for pumping to
protect pumps.
Maximum current protection:set maximum current protection is
available.
Minimum solar input power:When low power input,inverter no work.
Stop frequency:Lower than stop frequency,inverter no work.
Sleep mode:if lower than sleep voltage,inverter go to sleep,it will
wake up when DC voltage rise.
Flow and generated energy calculating and monitoring.
A lot of fault protection. Short circuit,ground short circuit,phase
loss,over current,overheat…
Built in RS485 interface,it is easy to connect GPRS remote
controller.
