Lithium Ion 150V 1750W To 2750W On /off Grid Tie Inverter

Solar On/Off Grid Energy Storage Inverter

Product Description

Solar On/Off grid energy storage inverter applied to solar energy storage micro-grid system.The system uses PV energy as priority.When the energy of PV is not enough,it can be supplemented by cith power or batteries.When the PV energy is surplus,the battery is stored or accessed on the grid to maximize the utilization of PV power generation,so as to achieve the purpose of self-use and extra power consumption.In addition,according to different customer’s and extra power consumption.In addition,according to different customer’s requirements,peak and valley time periods can be set pu to achieve peak-to-peak and valley-filling,reduce grid pressure,and maximize revenue.The system can compatible with lead-acid batteries and lithium batteries.In the event of a power grid failure,solar energy can continue to generate electricity and switch to off-grid mode to continue to supply power to the load.


  1. Integrated intelligent energy management system,a variety of modes can be set;
  2. Cut peaks and fill valleys to reduce grid pressure and maximize profits;
  3. Dual MPPT input,precise algorithm,efficient use of PV energy;
  4. Supports multiple parallel operations for user expansion;
  5. 5.3-stage/2-stage charging technology to protect battery life
  6. 6.Two-way energy storage design,PV,mains can charge the battery;
  7. 7.Support multiple remote monitoring of communication software(RS232RS485Mobile APPSNMPGSM)
