在Intersolar上，新的X8系列系统现已上市，该系统是一种可配置的设备，可作为光伏逆变器、BESS转换器和氢电池整流器运行。

Presented at Intersolar, the new X8 series system, a configurable device that operates as a photovoltaic inverter, BESS converter and hydrogen cell rectifier, is now available.

西班牙制造商Jema Energy公布了其新的X8系列逆变器系统，这是一种完全可配置的设备，可作为光伏逆变器、BESS转换器和氢电池整流器。

Spanish manufacturer Jema Energy has unveiled its new X8 series inverter system, a fully configurable device that functions as a photovoltaic inverter, BESS converter and hydrogen cell rectifier.

X8系列能够在1500 V DC标称功率下运行，在710 V下高达4.7 MVA。它在-20 C至65 C（可选高达-30 C）的温度范围内运行，并保持其标称功率高达40 C，90%高达55 C。其最大效率为99%，欧洲型号为98.6%。

The X8 family is capable of operating at 1500 V DC nominal power, with up to 4.7 MVA at 710 V. It operates in a temperature range of -20 C to 65 C (optionally, up to -30 C), and maintains its nominal power up to 40 C, with 90% up to 55 C. Its maximum efficiency is 99% and 98.6% for the European model.

BESS系统配置为四个小时，系统的模块化允许将多个电池容器集成到同一设备中。

The BESS system is configured for four hours, and the modularity of the system allows multiple battery containers to be integrated into the same equipment.

X8系统具有集成保护或保险丝，无需任何外部设备即可连接长达四个小时的存储。

The X8 systems have integrated protections or fuses that allow up to four hours of storage to be connected without any external equipment.

由于采用液冷，它可以实现更高的密度，在单个橇块中获得高达9兆瓦的完整系统。它可以与锂离子电池、氧化还原液流电池或钠电池一起使用。

Being liquid cooled, it allows higher density, obtaining complete systems of up to 9 MW in a single skid. It can be used with lithium-ion, redox flow or sodium batteries.

带有两个模块的IFX8光伏重3000公斤，高2350毫米，宽2900毫米，长900毫米。

The IFX8 photovoltaic with two modules weighs 3,000 kg and measures 2,350 mm in height by 2,900 mm in width by 900 mm in length.

X系列逆变器的技术允许它们在并网模式下运行，在开关状态下与电网连接或隔离。这种并网技术存在于BESS和光伏解决方案中。

The technology of the X series inverters allows them to operate in grid-forming mode, connected or isolated from the grid in on-off. This grid forming technology is present in both BESS and photovoltaic solutions.

X系列逆变器在停电或断电时提供的解决方案是黑启动：逆变器能够在不连接到电网的情况下自行启动和发电。

The solution offered by the X series inverters in the event of a blackout or power outage is Black Start: the inverter has the ability to start and generate energy on its own without being connected to the grid.

当多个转换器相互连接并协调其动作时，就会发生下垂控制，并联运行以产生和维持电网的电压和频率。这种解决方案允许以协调和自主的方式调整转换器的频率和电压，这是一种提供适应网络需求的响应的方式，而不需要中央控制。

Droop control occurs when several converters are connected to each other and coordinate their actions, operating in parallel to generate and maintain the voltage and frequency of the grid. This solution allows the frequency and voltage of the converters to be adjusted in a coordinated and autonomous manner, a way of providing a response adapted to the needs of the network without the need for central control.

据制造商介绍，“新的多级拓扑结构不仅允许在整个直流电压范围内全功率运行，而且在高空安装中提供了更高的密度和性能。”

According to the manufacturer, “the new multi-level topology not only allows full power operation across the entire DC voltage range, but also provides greater density and performance in high altitude installations.”
