（Including:40W/12V、50W/12V、60W/12V、150W/12V、300W/12V、1000W/24V、1200W/24V、1500W／24V、2000W/24V）

 “WRI”Solar Converter is equipped with Voltage and Current Meters for battery, Indicator LCD for Electrical source, Power-off Protection Indicator LED and AC Circuit Breaker in its surface and backside.

 “WRI” Solar Converter other functions Reverse polarity protection, overload protection, short circuit protection, thermal protection and so on.

1、 Reverse polarity protection: Incorrect connection causes that no current passes the Converter, so it won’t ruin the Converter (The hand of Voltage Meter will point to the reverse direction).

2、 Overloading protection: When Converter is connected the excessive loads and the total power of loads exceeds its tolerance, it will stop working within ten seconds. Then the red LED will get light and the Converter will turn into the self-protection state. After reduction of the load, turn the power switch “ on-off” to the “OFF” over ten seconds and then turn it into the “ON”, the Converter will renew to work. (Meeting the malfunction, AC Circuit Breaker on the back of Converter will automatically spring down. Before its startup, please push up the Breaker.)

3、 Short circuit protection: When the interior of the appliance starts short circuit, the Converter will stop working within one second and turn into the self- protection state. Remove the malfunction; turn the power switch “on-off” to the “OFF” over ten seconds, turn it to the “ON”, then the Converter will renew to work. (Meeting the malfunction, AC Circuit Breaker on the back of Converter will automatically spring up. Before its startup, please press down the Breaker.)

4、Temperature protection: For the load is too much or the environmental temperature is too high, the interior temperature of Converter will get higher, so the Converter will stop working and turn into the self-protection state. (Suggest to reduce the quantity of loads or improve the ventilation, and then turn the switch “on-off” to the “OFF”. After the interior temperature gets lower, then turn it to the “ON”, the Converter will renew to work.

Sine wave output : Can offer sensibility load and other kind of loads, such as electric fan、refrigerator、air-condition、 electromotor and computer and so on.

Mono-microcomputer controlls the solar Converters: It produces the wave’s shape and makes the frequency of the Converter stable including auto-controll voltage.

Low down the speed of open: When we used high power loads, the Converter can low down the speed of open in order to protect the electrical products on load and itself.

Overloading protection: When Converter is connected the excessive loads and the total power of loads exceeds its tolerance, the Converter will be sound and the red LED will get light .Then the Converter will stop working and turn into the self-protection state.

    Short circuit protection: When the interior of the appliance starts short circuit, the Converter will stop output and lock up. Then the red LED will get light and the Converter will turn into the self-protection state.

Discharge protection: When the voltage of the battery is lower than21.5V, the Converter will be sound and the LED will get light. Then the Converter will be stop output and lock up with in 5 minutes.
