LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display.
Off Grid Inverter 3.2 Inverter Identification There is nameplate on the side of inverter, the nameplate shows the inverter model, some important parameter info, and certificate mark. Figure3-1 Inverter nameplate NO.
Off Grid Inverter 4.1 Prepare Installation Tools Before installation, some preparation is necessary. Inverter and wire installation will need some form of the following tools. Sketch map Recommend Name Function specification 6~50mm2 Wire Used for crimping input and output terminals connected to crimpers the wires Ф8 Cross screwdriver Used for the input and AC output wires installation Table4-1 Installation tools list 4.
Off Grid Inverter Table4-2 Installation process table 5 Installation 5.1 Installation Site Inverter installation site environment is very important to the safe operation, performance, and life of the inverter. ● All installation procedures must comply with local and national electric standards. ● Do not install the inverter in a flammable or explosive place or a place where the flammable or explosive materials are stored. ● Do not install the inverter in a place where there is a risk of explosion.
Off Grid Inverter 5.2 Installation Direction ● The inverter should be installed vertically. ● Do not install on uneven ground. ● Never install the inverter horizontally. ● The installation place of inverter should be convenient for operation and reading out of the LCD displayed information ● Do not install the inverter in a place where children can touch. ● The inverter uses fan cooling.
Off Grid Inverter input breaker to restart the machine. 5.3.10 Put the inverter in well ventilated area away from sunlight, confirm that distance between the inverter and any wall is greater than 30cm. 5.3.11 DO NOT block air vents. If it is discovered that the vents are blocked, please clear any obstruction immediately. 5.3.12 If temperature starts to rise when the inverter is running normally, check to see if the fan is still operating correctly.
Off Grid Inverter on smaller loads. The fan only will run when cabinet internal temperature exceeds 45 ℃. 5.4.3 – DO NOT open the cover of cabinet when the inverter is running, doing so could cause electric shock! 5.4.4 – DO NOT change any circuitry or wiring that has been preinstalled on the inverter. 5.4.5 – It is a normal phenomenon that the inverter warms up during nominal function. Keep the environment around inverter cool and clean, ensuring proper ventilation at all times. 5.4.
Off Grid Inverter Always ground the system properly, using appropriate conductor and providing necessary short-circuit protection to ensure safe operation. DO NOT turn on any breakers before all connections are secure and complete 6.1 Connecting Terminals of inverter The input and output terminals are installed in the bottom of the inverter and include DC side input terminals and AC side output terminals.
