Product Overview:

Zhejiang Saikong SN360 380V three phase 18.5kW series solar pump frequency inverter passed several years R&D to solar photovoltaic field and then design this solar inverter, according to the characteristic of the working principle of solar PV panels and power supply.

Product Features:

◆ Using advanced MPPT control technology, real-time detection of solar panels power voltage, tracking the highest voltage and current, charging to battery with the highest efficiency.

◆ Using shuttle center keyboard high accuracy encoder, controlling accuracy 0.01HZ, having multiresolution setting function, easy operation and use.

◆ Using multiple power supply design, power input can use solar energy photovoltaic DC power supply, can also be a single-phase, three-phase AC power supply, simple wiring.

◆ Using wide voltage design. The inverter can remain stable under high and low voltage work with strong adaptability.

Multi communication modes:

SAFESAVE inverters built-in RS48S communication isolated module, adopt MODBUS RTU C contract for mainly communication Through PC/PLC control PC such economical, reliable fieldbus network to achieve centralized control Set and modify SAFESAVE inverters control command, running frequency and relevant parameters to monitor the working status or fault information
