请记住你使用的是一款发电产品，因此为了避免意外事故的发生，需要采用相应的安全措施。

请确保组件连接以后产生的电流、电压值在此阵列所连接的其他装置的电流、电压值的适用范围之内，不超过太阳能组件能承受的最大系统电压。

如果组件安装在屋顶的话，必须安装具有一定防火能力的屋顶上，可以咨询当地的建筑部门来决定使用何种屋顶材料。

太阳能组件应用等级为A：危险电压（IEC 61730：高于50V DC；EN 61730：高于120V），危险功率（高于240W），根据EN IEC61730-1和-2标准，组件质量满足安全要求且安全等级为II。

1.2 警告●当组件暴露在太阳光或者其他光源下，组件内有直流电流产生，此时与组件的电气部分接触可能会发生触电危险。

●不要用镜子或透镜聚焦阳光照射到太阳电池组件上，不要将组件背面直接暴露在太阳光下。

●太阳能电池组件的前玻璃具有保护组件的作用，破损的太阳能组件具有电危险性（电击和着火），这样的组件不能修复或维修，应该立即更换掉。

●普通室外条件下，组件产生的电流和电压与参数表中列出的有所不同。

参数表是在标准测试条件下测得，所以在确定光伏发电系统中其它部件的额定电压、导线容量、保险丝容量、控制器容量等和组件功率输出有关联的参数时，参照标在组件上的短路电流和开路电压的值，并按125%的值设计和安装。

Victron Energy Multi RS 48 6000 双轨式 PV 输入混合逆变器说明书

Victron Energy B.V. | De Paal 35 | 1351 JG Almere | The Netherlands E-mail: *********************** Operating modesHybrid mode – Stores excess solar energy in a battery, to be used during the night or periods of high demand. Supplies additional power from the battery when demand exceeds grid capacity. Backup mode – Switches to backup mode during a grid outage. Off-grid mode – Operates without grid connection.Generator mode – Controls the generator to minimize run-hours. Supplies additional power from the battery when demand exceeds the capacity of the generator.PowerControl and PowerAssist - Boosting the capacity of the grid or a generatorA maximum grid or generator current can be set. The Multi RS will then take account of other AC loads and use whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl function).PowerAssist takes the principle of PowerControl to a further dimension. Where peak power is so often required only for a limited period, the Multi RS will compensate insufficient generator or grid power with power from the battery. When the load reduces, the spare power is used to recharge the battery.Display, Bluetooth and VictronConnect appThe display reads battery, inverter and solar parameters. The same parameters can be accessed with a smartphone or other Bluetooth enabled device, using the VictronConnect app.Extendable PV capacity, both AC-coupled and DC-coupledThe integrated 6 kWp PV capacity can be extended by adding solar chargers to the system.Alternatively, the PV capacity can be extended by installing PV Inverters, of which the output power will be automatically controlled by the integrated frequency shift power control.Communication portsVE.Can connection to a GX device for system monitoring, data logging, and remote firmware updates.
