Solar inverter 3.Insert of battery cable flatly into battery connector of inverter and make sure the bolts aretightened with torque of 2-3 Nm.Make sure polarity at both the battery and the inverterlcharge is correctlyconnected and are tightly screwed to the battery terminals. Battery Connection CAUTION: For safety operation and regulation compliance, it's requested to install a separate DC over-current protector or disconnect device between battery and inverter.It may not be requested to have a disconnect device in some applications, however, it's still requested to have over-current protection installed.Please refer to typical amperage in below table as required fuse or breaker size. lt's very important for system safety and efficient operation to use appropriate cable for battery connection.To reduce risk of injury, please use the proper recommended cable. Recommended battery cable and terminal size: Model 1KW/2KW Typical Amperage 84A BatteryCapacity 100AH 200AH Wire Size 2*8AWG Torque Value Please follow below steps to implement battery connection: 1.Assemble battery ring terminal based on recommended battery cable and terminal size. 2.The 1KW model supports only 12VDC systems. The battery string connection is The chart below. For 1KW models, you are advised to connect a battery with a capacity of at least 100Ah. Inverter 1KW Inverter 2KW 12V 12V 12V 12V 09 WARNING: Shock Hazard Installation must be performed with care due to high battery voltage in series. CAUTION!! Do not place anything between the flat part of the inverter terminal and the. Otherwise, overheating may occur. CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals areconnected tightly. CAUTION!! Before making the final DC connection or closing DC breakerldisconnector, be surpositive (+) must be connected to positive (+) and negative (-) must be connected to negative(-). AC Input/Output Connection CAUTION!! Before connecting to AC input power source, please install a separate AC breaker betweeninverter and AC input power source.This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 15A for 1KW. CAUTION!! There are two terminal blocks with "IN" and "OUT" markings.Please do NOT mis-connect inputand output connectors. WARNING! All wiring must be performed by a qualified personnel. WARNING! lt's very important for system safety and efficient operation to use appropriate cable for AC inputconnection.To reduce risk of injury, please use the proper recommended cable size as below. Suggested cable requirement for AC wires Model 1KW 2KW Gauge 14AWG 12AWG Torque Value 0.8 ~ 1.0 Nm 1.2 ~ 1.6 Nm Please follow below steps to implement AC input/output connection: 1.Before making AC inputloutput connection, be sure to open DC protector or disconnector first. 2.Remove insulation sleeve 10mm for six conductors.And shorten phase L and neutral conductor N 3 mm. 3.InsertAC input wires according to polarities indicated on terminal block and tighten the terminal screws. Besure to connect PE protective conductor ( ) first. 10 Solar inverter 4.Then, insert AC output wires according to polarities indicated on terminal block and tighten terminal screws.Be sure to connect PE protective conductor ( ) first. 5.Make sure the wires are securely connected. Solar inverter CAUTION : Important Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may causeutility short-circuited when these inverters are worked in parallel operation. CAUTION: Appliances such as air conditioner are required at least2~3 minutes to restart because it's requiredto have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in ashort time, it will cause damage to your least2~3connected appliances. To prevent this kind of damage, please checkmanufacturer of air conditioner if it's equipped with time-delay function before installation. Otherwise, thisinverterlcharger will trig overload fault and cut off output to protect your appliance but sometimes it still causesinternal damage to the air conditioner. PV Connection CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker betweeninverter and PV modules. WARNING! All wiring must be performed by qualified personnel. WARNING! lt" very important for system safety and efficient operation to use appropriate cable for PVmodule connection.To reduce risk of injury, please use the proper recommended cable size as below. Model 1KW / 2KW Typical Amperage 60A Cable Size 8AWG Torque 1.4~1.6 Nm PV Module Selection: When selecting proper PV modules, please be sure to consider below parameters: 1.Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter. 2.Max.power voltage (Vmp) should be during PV array MPPT voltage range. Solar Charging Mode INVERTER MODEL Max.PV Array Open Circuit Voltage PV Array MPPT Voltage Range 1KW 105V 15Vdc~90Vdc 2KW 145V 30Vdc~120Vdc Please follow below steps to implement PV module connection: 1.Remove insulation sleeve 10 mm for positive and negative conductors. 2.Check correct polarity of connection cable from PV modules and PV input 11 12 Solar inverter connectors.Then, connect positive pole(+) of connection cable to positive pole(+) of PV input connector. Connect negative pole (-) of connection cable to negative pole (-) of PV input connector. OPERATION Power ON/OFF Solar inverter 3.Make sure the wires are securely connected.
