Do not connect the load in excess of the inverter’s maximum input power, otherwise, the inverter may be damaged.2. Installation2.1 Warning•Please read the manual carefully to get familiar with the installation steps before installation.•Be very careful when installing the batteries, especially flooded lead-acid battery.Please wear eye protection, and have fresh water available to rinse if any contact with battery acid.•Keep the battery away from any metal objects, which may cause a short circuit of the battery.•Loose connections and corroded wires may result in high heat that can melt wire insulation, burn surrounding materials, or even cause a fire. Ensure tight connections and use cable clamps to secure cables and prevent them from swaying in motion.•Select the system connection cables according to the current density no higher than 5A/mm2.(In accordance with the National Electrical Code Article 690, NFPA70).•For outdoor installation, keep out of the direct sunshine and rain infiltration.•High voltage still exists inside the inverter after turning off the switch, do not open or touch the internal devices, wait five minutes before conducting related operations.•Please do not install the inverter in humid, greasy, flammable, explosive, dust accumulative or other severe environments.•Prohibit reverse connection at the battery input end; otherwise it will easily damage the equipment or cause unpredictable danger.•Both utility input and AC output are of high voltage;please do not touch the wiring connection.• When the fan is working, please do not touch it to avoid injury.2.2 Wire& breaker selectionWiring and installation mode should comply with national and local electrical code requirements.••TP30KBIMPORTANT: The wire size is for reference only, use thicker wires to lower the voltage drop and improve the system performance when the distance between utility and inverter or between inverter and batter is far.IMPORTANT: The above wire size and circuit breaker size are for recommendation only, please choose suitable wire and circuit breaker according to the practical situation.2.3InstructionsInstallation steps:Step1:Professional personnel read this manual carefully.Step2:Determine the installation location and heat dissipation space.Move the equipment: as the equipment is relatively large, it is recommended to use forklift or crane; if the ground is flat, it can be moved by wheels.Place to the location: As the equipment is heavy, it is recommended to be placed on flat ground, with 300mm space reserved all around, to ensure heat dissipation.Fix the equipment: If choose the optional caster, rotate counterclockwise to fix and rotate clockwise to move.WARNING: Risk of explosion!Never install the inverter with flooded batteries in a sealed enclosure! Do not install the device in a confined area where battery gas can accumulate.Step3:Take down the junction box cover plate with special tools.Step4:WiringWiring order:❶Ground——❷Battery——❸Utility——❹AC loadsWARNING: Never connect the utility to the inverter output; otherwise the inverter may be damaged.•GroundingThe voltage of the whole system exceeds the safety voltage level. Thus reliable grounding is needed. The grounding wire shall be the thicker wire(no less than 35mm2), and shall be as short as possible. The grounding point shall be as close as possible to the inverter.CAUTION: When wiring, follow the order ❶❷❸❹ to connect the cables to the equipment, then follow the order ❶❷❸❹ to connect ground, battery, utility and load.WARNING: Make sure all the wiring connections are reliable, otherwise massive heat would accumulate at the connection points to damage the terminals, or even cause a fire.WARNING: Danger, high voltage! Utility input, AC output and DC input will produce high voltage, do not close the breakers during wiring, and make sure the correct polarity of each component.Step5:Connect accessories•Mobile APP(For Android only)Download software:—EPEVER(TP)Communication cable: M12-6-male pin + crystal head-1000mm-v1.0Modules: eBox-WIFI-01 and eBox-BLE-01•PC SoftwareDownload software:—Inverter Monitor(TP)Communication cable: 1.M12-6-male pin + crystal head-1000mm-v1.02.RJ45 Coupler3.

Especially for inductive loads, should be turned on one by one. Do not turn on the loads at the same time, so as not to cause excessive impact to the inverter, to shorten its life span.CAUTION: In case the inverter is not in regular operation, or LCD or indicator displays abnormal, refer to Section 5 to clear the fault or contact the after-sale service personnel of our company.Step12:Power off the equipmentOpen the AC load circuit breaker—long press “AC output” button to turn off the inverter output—open the bypass circuit breaker—open the battery circuit breaker.WARNING: As electricity exists in the capacitance, the LCD screen would be off after 30 seconds; wait 5 minutes before opening the equipment to repair.WARNING: After the inverter is disconnected from utility and battery bank, need to wait 5 minutes before touching the internal conductive devices.WARNING: As the inverter has soft stat design and only takes effect when the first time it starts, do not frequently switch the input circuit breaker when the inverter is incompletely powered off, otherwise the input battery would undergo high current impact. That is, the input circuit breaker can be closed again after the LCD screen is off.2.4Output voltage/frequency grade switchWhen the dial switch 1 is placed to the ON side, the outputfrequency is 60Hz, otherwise it is 50Hz,When the dial switch 2 is placed to the ON side, the outputvoltage is 230VAC, otherwise it is 220VAC.Operating steps:Open the cover plate on the inverter right side, find the dial switches on the control board which is located on the top left corner, see above picture. Set the outputvoltage/frequency according to demand, then restart the inverter to take effect.IMPORTANT: The factory default output voltage is 220VAC, the output frequency is 50Hz.IMPORTANT: The accessories can refer to the Packing list.3.

Clear up any dirt and fragments on the radiator.•Check all the naked wires to make sure insulation is not damaged for serious solarization. Frictional wear, dryness, insects or rats, etc. Repair or replacesome wires if necessary.•Check and confirm that indicator and display is consistent with required. Pay attention to any troubleshooting or error indication .Take corrective action ifnecessary.•Confirm that all the terminals have no corrosion, insulation damaged, high temperature or burnt/discolored sign, tighten terminal screws to the suggested torque.•Check for dirt, nesting insects and corrosion. If so, clear up in time.•Check and confirm that lightning arrester is in good condition.

LCD触摸控制屏用户可通过触摸屏察看设备的运行信息,实现外部控制与通讯功能(LCD无通讯功能),具体功能如下:✧控制逆变器运行✧显示逆变器状态✧显示逆变器实时运行数据✧显示故障信息✧设置运行参数✧提供多种通讯接口(CAN,RS485,以太网)钥匙锁定开关用户可以通过钥匙开关,进行触摸屏功能的锁定。

当钥匙开关旋转到STOP 位置,LCD触摸屏将会被锁住。

避免运行过程中,不慎触碰触摸屏,导致错误指令的发出。

当钥匙开关旋转到START位置,触摸屏被解锁,可以进行逆变器的控制与运行数据的查看。

急停按钮按下此按钮后,逆变器立即停机,交流接触器断开。

若要重新启动设备,需要顺时针旋转急停按钮,松开急停按钮,通过触摸屏重新发出运行指令。

交流侧断路器交流断路器控制交流电路的通断,可以实现逆变器输出与电网的断开。

如上图所示位置,逆变器交流断路器处于断开位置,顺时针旋转90度,可以使交流断路器闭合。

此时可以启动逆变器运行。

直流隔离开关直流隔离开关控制直流段电路的通断。

图中所示位置逆变器隔离开关处于断开位置,顺时针旋转90度,可以使隔离开关闭合。

4 产品功能与LCD操作指南关于本章本章主要介绍GDLYEC-PV-3~270/500的主要功能与运行模式,以及如何通过LCD进行设置4.1 GDLYEC-PV-3~270/500主要功能4.1.1 并网发电GDLYEC-PV-3~270/500并网逆变器上电自检成功后,设定好系统参数及控制参数,设备会自动检查光伏阵列端口的电压,交流侧电网条件,如果都在逆变器运行允许范围之内,通过LCD发出“运行”指令,逆变器启动运行。

GDLYEC-PV-3~270/500并网逆变器具有优良的并网功能,在启动阶段通过电压控制,实现逆变器输出电压与电网电压的同步,以减小接触器闭合时产生的冲击电流,在关机时,通过软关机实现对电网的零冲击,因此是一款电网友好型的并网逆变器。

4.1.2 MPPT功能GDLYEC-PV-3~270/500并网逆变器具有快速、高效、宽范围(420V~820V)的MPPT功能。

GDLYEC-PV-3~270/500并网逆变器所用MPPT技术的技术特点:1)采用变步长的扰动观察法,兼顾了追踪的快速性与追踪之后的稳定性。

2)采用多个电压点功率检测与单个电压点功率检测结合的方法,减小了扰动观察法误动作的可能。

3)充分考虑不同天气状况(如晴天,阴天,多云等)光伏阵列的PV曲线的不同,针对不同状况有针对性进行追踪。

4)充分考虑在光伏阵列峰值的左右两侧曲线坡度的不同,采用不同的追踪策略进行处理。

4.1.3低电压穿越功能GDLYEC-PV-3~270/500并网逆变器具备低电压穿越功能。

在光伏并网点电压跌落的时候,设备能够保持并网,支持电网恢复正常。

电网正常时逆变器工作在MPPT模式。

当发生电压跌落时,逆变器输出的电流迅速增大,这时逆变器工作模式由MPPT模式转化为电流控制模式,逆变器输出最大的电流I max 并保持并网运行,在逆变器交流侧电压跌至20%标称电压时,逆变器能够保证不间断并网运行1秒; 随着电网电压的回升,逆变器重新恢复到MPPT 模式,当逆变器交流侧电压在跌落后3秒内能够恢复到标称电压90%时,逆变器能够保证不间断并网运行。

并网逆变器实现低压穿越过程如图4-1所示:nU 0.20.40.60.81-01T 2T INI I 1213T s T s==图4-1 低电压穿越示意图4.1.4 保护功能GDLYEC-PV-3~270/500并网逆变器具有完备的保护功能,主要有: ● 交流过/欠压保护 ● 交流过/欠频保护 ● 反相序保护 ● 防孤岛保护 ● 过载限功率保护●过温限功率保护●交流过流保护●直流过流保护●直流过压保护●极性反接保护●短路保护●过温保护●方阵对地绝缘阻抗检测及保护GDLYEC-PV-3~270/500并网逆变器的保护值和保护时间可根据用户现场的环境和电网条件进行设定。
