Huawei introduced a new high power string inverter SUN2000-330 KTL Designed specifically for utility-scale solar installations, the high-performance inverter SUN2000-330KTL, boasts an impressive output of 330 kilo-Volt-Amperes (kVA), making it capable of efficiently handling substantial power loads.

The SUN2000-330KTL stands out with its compact design, allowing for seamless installation in various solar setups. With an EU efficiency rating of 98.8%, it excels in conversion efficiency and ensures optimal energy production. Versatility is a key feature of the SUN2000-330KTL, supporting a wide input current range that accommodates solar modules with cell sizes of 162 mm, 182 mm, and 210 mm. This flexibility enables system designers to work with different module types, offering greater freedom in system design. On top, the SUN2000- 330KTL allows for "module replacement without inverter replacement," reducing complexity and costs associated with procurement, spare parts, and maintenance. an integrated IV Diagnosis Tool, it reliably detects errors or issues in the photovoltaic installation, facilitating timely troubleshooting and optimal system performance. To ensure the safety and longevity of the product, the SUN2000-330KTL provides robust protection against errors on the direct current (DC) side of the PV installation, offering quick and reliable safeguards.

Moreover, the SUN2000-330KTL incorporates industry-leading triple protection functions, including Smart String-level Disconnection (SSLD-TECH), Smart Connector Level Detection (SCLD-TECH), and Smart DC Insulation Diagnosis. These features accurately identify and address issues such as reverse connection of the connector, backflow of current, and short circuits, implementing selfprotection within milliseconds.

It also holds L5 authoritative certification for Power Line Carrier Communication from CGC, enabling stable communication over long distances of up to 1,000 meters, supporting sub-arrays with a maximum capacity of 9 MW. Additionally, the SUN2000-330KTL features industry-leading Smart Self-cleaning technology, significantly improving dust removal efficiency and reducing maintenance costs.

Additionally, the Huawei FusionSolar Residential Smart String ESS LUNA-2000-7/14/21-S1 is an outdoor modular residential storage system. Depending on the user's needs, the system is available in capacities of 7, 14, and 21 kWh. Furthermore, for larger capacity requirements, up to 4 systems can be seamlessly connected in parallel, achieving a maximum collective capacity of 84 kWh. The system's battery cells are made of lithium-ironphosphate and offer an exceptional 100% depth of discharge. Designed with longevity in mind, the entire system promises a lifespan of 15 years (see Day 1 Highlights From Intersolar Europe 2023).
