Video of SN360 Series solar frequency inverter
SAFESAVE SN360 Series solar pump frequency inverter passed several years R&D to solar photovoltaic field and then design. This solar inverter is a high quality, multi-function SVC inverter, based on the European power and latest control theoretical and technological achievements and combining with the latest market power technology application requirements. By decoupling control of motor magnetic flux current and torque current torque to reach fast response and accurate control, you can run a wide range of speed and torque control in high-precision.
1. Without interference on the motor and driven load
2. Perfectly integrated in the control system
3. Lower energy costs
4. Production efficiency improved
5. Easy to operation
6. High-quality services
7. Commissioning guide:
The time when the inverters operated to the lower limit of P output frequency after starting is determined by the ACC time
The instruction of delay time. If various delay conditions such as weak light, full water, and underload are met, the inverter will count the delay time respectively. After the separated delay time is arrived, it will report pre-warning and others are still kept. If the pre-warning is restored, but other conditions for delay are still existent, it will count after the precious time. So if the some pre-warning condition is not met, the pre-warning time will be cleared.
