Two Work Mode
1. PV—Grid—Battery: This series solar inverter is designed for real-time sharing function between solar power and utility power. Solar power priority, solar power supply power to inverter via MPPT controller, and then output pure sine wave AC power to load via inverter, meanwhile charge battery. When solar power is not enough, the utility power will supply power to load. In this way, we can maximum use solar power and utility power, reduce battery discharge time and extend battery lifespan.
2. PV-Battery-Grid ( Maximum use solar power under the stable environment of utility power ): Solar power supply power to inverter via MPPT controller, and then output pure sine wave AC power to load via inverter, meanwhile charge battery. When the solar power is not enough, to maximum use solar power, the battery will supply power to load. When the battery is discharged to a value, the utility power will supply power to load. The users can maximum use solar power, reduce grid power supply and save electricity.
High efficiency IGBT (Insulated Gate Bipolar Transistor）inverter technology: the 6th generation IGBT has the nature of lower saturation voltage drop, higher efficiency of inverter, lower heat, more reliable.
Instinctive LED status display, work status can be seen at a glance by workflow indicator.
Perfect protection function: Input/output over/low voltage protection, input surge protection, phase protection, battery overcharge-over discharge protection, output overload shortcut protection, overheat protection and alerting.
Two charging mode: AC charging mode and solar charging mode, solar charging priority. Can choose AC charging current 0A-3A-6A by panel switch
Can choose two work mode: Solar-Grid-Battery, Solar –battery-Grid, Can choose it by LCD screen
Solar power & Grid power priority (when battery voltage is 11.2v, low voltage and power off), Under no grid power, solar power is normal, it can automatic restart the inverter (single cell voltage 12.5v automatic restart)
Intelligent communicate: With RS232 and RS485 standard collocation, optional SNMP and dry contact.
Selectable battery inspection module – Can test the single parameter and display on the LCD, battery failure will immediately alarm and inform the administrator.
