20KW/120VDC three phases off grid solar Inverter

Three phase off grid solar inverter

Introduction

Our wind / solar off grid inverter include the grid hybrid function (AC input bypass power for back up). Main work procedures as below:

1-1)     Wind / solar priority. Take wind / solar to supply power as the first choice; when the wind / solar power cannot afford the inverter, it will take power from battery as supplementary. By this way it can prolong the battery’s lifetime.

1-2)     When the battery is low voltage to run the inverter, inverter will transfer to the mains / AC bypass or diesel generators etc. other back up power sources automatically.

1-3)     When the battery voltage goes up, inverter will transfer to battery mode automatically.

1-4)    Because of wind / solar priority, battery only works when wind / solar power is not enough and the battery will not discharge deeply; therefore the battery’s lifetime can reach more than 5 years, greatly prolonged the battery’s lifetime.

Features:

1) Intelligent battery management system can extend battery’s life.

2) LCD display, it can show: inverter work status, inverter output, battery voltage, output voltage, current, frequency, load level etc.

3) Solar priority. Solar always take precedence over the use of other power sources, maximize the use of solar energy.

4) When the solar charging current and battery bank is insufficient to supply all the power for the loads, the inverter switches automatically to mains bypass. Ensure uninterruptible power to the running loads.

5) When the solar power enough to power the loads, the inverter will automatically switched to the solar work mode.

6) Strong ability of resisting concussion, can load all kinds of electric apparatus and industry equipments, such as air conditioner, refrigerator, television, fan, washer, fill water electric motor, tortile gate, etc.

7) High transfer efficiency, up to 95% (different materials transformer has different transfer efficiency)

8) Protections: output short circuit, overload, low voltage, etc.
