1 security matters
This product has been designed with the user in mind personal and property safety, in order to ensure your safety and benefit, installation, use the following rules:
(1) Do not put uneven or sloping place.
(2) Avoid placing in direct sunlight, rain or moisture.
(3)Please keep away from fire and high temperature to prevent overheating.
(4) Avoid locations with corrosive gas
(5) If possible, place the unit in clean, well-ventilated place, left and back at least ten centimeters away from the wall, do not place objects on the machine, to prevent clogging cooling holes.
(6) Do not insert anything into or any liquid thrown into the enclosure.
(7) forbidden to open the chassis, if faulty contact qualified service technician or your retailer.

2 performance characteristics
(1) battery charging function: The inverter control one machine can continuously during the day by solar panels energy stored in the battery, the battery voltage can be adjusted according to the charging current to prolong battery life, the inverter control one machine also with a float function, so that the battery is always full of electricity needed to prepare for the state. In addition the machine to prevent nighttime battery to solar panel reverse charging.
(2) Battery undervoltage protection function: prolonged use of an inverter to your electrical supply will lead to a serious decline in battery voltage, which greatly affect battery life. The machine can turn off the battery voltage drops to 10.8V DC output, 10.5V turn off the AC output. To prevent the battery over-discharge damage.
(3) Battery voltage protection function: The inverter is normal input voltage of 12V, if the input voltage exceeds 16.5V, the inverter will take protective measures to prevent excessive input voltage cause damage to the machine itself.
(4) overload protection function: When you access too many appliances, the total power exceeds the rating of the inverter, it will stop working within 10 seconds, the lock protection status, and alarm, until you reduce the load, and the inverter power switch to the "OFF" position 10 seconds or more, then back "ON" position, the inverter will renew to work.
(5) Short-circuit protection: When your appliance internal short-circuit occurs, the inverter will stop working within 1 second, and lock protection status, and alarm, until you remove the short-circuit and inverter home appliances power switch to the "OFF" position 10 seconds or more, then back "ON" position, the inverter will renew to work.
(6) temperature protection function: When you load too much or poorly ventilated hot weather, the temperature inside the inverter will be gradually increased, if the temperature continues to rise to 100 °C inverter will stop working, and lock protection status, I suggest you reduce the load or improve ventilation, the inverter power switch to the "OFF" position, until the internal temperature drops, the dial to the "ON" position, the inverter to resume work.
(7) Status indication function: fault indication, the inverter instructions, and multi-functional LCD or pointer meter display, all at a glance.
(8). DC5V and DC12V Output: DC output ports for your devices charging and DC power supply function. 

3The method of operation
   Installed before using the machine, please read the following safety precautions and related content, fully understand its contents before operation, to avoid danger! Please click the following ways:
(1 )Prepare the associated installation tools (such as wrenches) and accessories (such as the DC power cord), and check the machine's installation location meets the requirements of safety precautions.
(2) Check the battery or battery pack voltage is within the required range (see Specifications section of this manual), have confirmed the positive battery or battery pack (red mark) and negative (black mark) and the machine is connected to the battery input cable (red) and negative cable (black).
(3) Disconnect the circuit breaker on the machine, turn off the inverter power switch.
(4) The machine battery input positive red cable to connect the battery or battery positive (red), enter a negative black battery cable battery or battery negative (black) to ensure that all joints, reliable, secure connection, ban this battery positive reverse polarity, ban any conductor will this battery positive and negative plates short, carefully check the firmness of each connection, such as the connection is not tight may cause localized overheating or even burning.
(5) closed circuit breaker on the machine, this time if fully charged, the normal power supply DC output port, LCD meter would normally indicate. Open the front panel of the inverter power switch, then INVERT indicator light, AC output universal socket for the use of electrical power (note the total rated power of appliances, do not exceed the inverter rated power)
(6) erecting solar panels facing the sun's position to the outdoors, then the output of solar panels leads to the solar panels on the machine input (note the distinction between positive and negative, solar panels connecting line through the current should not exceed 3A/mm2) At this point if sunny, LCD meter will charge status indicator.
  Note: Please strictly follow the instructions to install the circuit breaker only in the event of a major failure will automatically disconnect the system to normal operation after Please do not disconnect the circuit breaker. If you have to disconnect, be sure to remove solar panel input. Install again, first close the circuit breaker, and then connect solar panels.
