                Off-Grid Solar Inverter 10KVA-120KVA

                EA-GF series products use high speed DSP control unit, advanced high speed IGBT, MOSFET components, with pulse width modulation (SVPWM) technique disturbance type MPPT control, and double conversion system configuration. Under high-speed DSP system control, the system can quickly track panels to do high-power, load change and efficient multi-level control system, even if the mains input voltage and frequency suddenly change, over/under voltage, or power disturbances, it also can ensure provide the load with regulated voltage and frequency power. System has a reliable, environmentally friendly, high intelligence and other characteristics.

                Characteristics
                Villa, hotel, residential security, large base station, office, small manufacturing enterprises, computing centers, industrial automation equipment, network room, IDC data center, banking equipment, securities, health care, transportation, petrochemical and other solar systems. 
                ● High reliability:
                   ※ High-speed micro-controller DSP digital control technology to achieve real-time control, parameter setting, data detection, self-test function to ensure high reliable operation of the system.
                   ※ With high speed switching characteristic, high voltage, high current, low internal resistance, low dissipation IGBT, MOSFET power components based, to ensure system security and reliability.
                ● N+1 modularized MPPT tracking system:
                   ※ Multipath MPPT control system access, independent input, operation. More suitable for roof project, to improve power generation efficiency of the panels.
                ● PV proactive power supply function:
                After detects PV energy, system will enter MPPT status automatically, and it will also adjust the power distribution, priority in the use of PV energy.
                ● Intelligent battery management system:
                   ※ In this system, AC rectifier 、MPPT controller controlled by intelligent data exchange and communication system,user can set the battery capacity by themselves;battery configuration can be set by the operator interface,system will automatically 
                adjust the charging current ,charging voltage and charging mode.
                   ※ In special cases,international technical engineer can adjust the charging rate  and battery number according to the system configuration.
                ● Plenteous communication interface:
                   ※ RS485、RS232 (standard),SNMP(Option).
                   ※ Input dry contacts to switch on/off inverter, clear abnormal, EPO remotely. Output dry contacts singles for remote alarm. 
                ● Intelligent storage staggering features:
                System with intelligent peak load shifting function, the user can set the appropriate time period electricity according to the local electricity policy, to achieve load shifting features directly in order to bring economic value;
