1 Summary

1.1 Product Overview:

This series product is developed by R&D experts of our company based on their decades of the research experience in the solar power system characteristics, MPPT, combined with household equipment electricity requirements. It is a set of PV power generation, energy storage, load shifting adjustment and other functions in one of the hybrid inverter.

This system can realize solar MPPT, power shifting, load shifting and uninterrupted power supply.

The system is equipped with high speed digital DSP core control devices, combined with the SVPWM control technology. Under high speed DSP control, the system can track generating and using electricity speedily, so that can adjust stored energy or supply power fast.

Application:

Home; Villa; Hotel; Security and protection and other solar generating and storing system

1.2 Denomination for Product

For example:

HE 2K - 48V - 220V 220V: AC Output voltage 220Vac; 48V: DC input voltage 48VDC; 2K: rated power 2000W; HE: hybrid type

1.3 Safety Notice:

Keep above 50cm away from display, TV while installing the product. It is normal that the case surface temperature go up to 50 during using; Do not use inverter with overload; Do not open inverter cover in case danger of electric shock, maintenance should be handled by technicians; Inverter inner short circuit will cause electric shock or fire danger. Do not put any liquid vessel on inverter. Cut off power rapidly if inverter work abnormal, and contact with local dealers or EAST Service office. Make sure not to keep or use the product in following environment

No good air circulation Place having flammable gas corrosive material or lot of dust Place under abnormal high or low temperature(above 40 or below 0), or high humidity(above 90%) Place where with direct sunlight or near the heating appliance Place where violent vibration Outdoor

In case of fire, please use the surrounding dry powder fire extinguisher. The use of liquid fire extinguisher has lead to danger of electric shock.

Please install small breaker in the input terminal, so that in emergency situation the socket can be pulled out and cut the power supply.

Warning

The equipment must connect to the ground, when connect to AC, make sure the ground connection is reliable.
