Product introduction
This dual power transfer controller is used between an off-grid system and the public power.the controller is separately connected with public power, interter, battery and load, as the picture shows, in the top of the controller, there is an on/off switch, pls turn on the controller after ensure all the cables are well connected.
The controller can work with both solar system and wind system.
There are 5 indicators at the upside of the controller
(1) public power indicator
(2) inverter indicator
(3) (4) (5) 3 battery state indicators
The battery indicators shows the power state in battery as 75%,50% and 25%.
System working specification:
Process 1:when the battery is fully charged by solar panel,or battery power over 75%,inverter indicator (2) and battery state indicator (3) is shinning green. In this process ,power is provided by the off-grid system.
Process 2:when the power in battery is consumed to 50%,the inverter indicator (2) and battery state indicator (4) is shinning green.In this process,power is provided by the off-grid system.
Process 3: when the power in battery is consumed to 25%,public power indicator(1)is shinning green, and battery state indicator(5) is shinning red.At this time the battery voltageis lower than 10.5V or 21V, the controller will automatically change the power supplier to public in 10ms.In this process, power is provided by the state grid.
Process 4 :when the battery is charged by solar panel again, power is stocked in the battery until 50%,battey state indicator(4) and public power(1) is shinning green.In this process, power is still provided by the state grid, cause the battery voltage does not reach the over discharge return voltage point
Process 5:when the power in battery is over 75%,inverter indicator(2) and battery state indicator(3) is shining green.At this time the voltage return to 13.5V or 27V,the controller will automatically change the power supplier to battery in 10ms.In this process, power is provided by the off-grid system.
