The brochure specifies 135 kVA rated off-grid output and describes PV, battery, grid and generator integration, with optional PV MPPT equipment. ## Key features - Split-architecture wall-mounted microgrid PCS - IP65 enclosure; 98.1% maximum efficiency - 135 kVA rated off-grid output; 148.5 kVA maximum output per brochure - Grid-forming PQ / VF / droop / VSG control modes - Supports PV-storage-diesel and AC/DC-coupled project concepts - Parallel battery configurations with project-specific engineering ## Description LEONA-H135K is a wall-mounted, split-architecture energy storage PCS designed for commercial and industrial microgrids. Its independently arranged equipment supports service access, while the IP65 enclosure suits demanding installation environments. The brochure lists 135 kVA rated off-grid output, up to 148.5 kVA maximum output and 98.1% maximum efficiency. Product features Direct PV interface design can reduce the need for a separate combiner box; an MPPT controller is selected separately to match the array and project. AC coupling supports integration with existing PV inverters, while DC charging equipment can be incorporated into a PV-storage-charging system. Grid-forming controls include PQ, VF, droop and VSG modes. The system can coordinate grid-connected and off-grid operation, subject to project configuration. Parallel configurations can use one-cluster/one-management or centralized battery management. In parallel operation, SOC-based power adjustment can help balance battery clusters. PV-side reverse-polarity protection, buck-boost conversion options, remote EMS monitoring, event records and OTA functions are described in the supplied brochure. Separate equipment blocks simplify fault isolation and service. The brochure gives approximate split-unit weights of 85 kg for the converter and 60 kg for the MPPT controller. Solution configurations Typical concepts in the supplied material include PV-storage-diesel-charging microgrids, PV expansion with a 600 kWp array, one-cluster/one-management parallel microgrids, AC-coupled PV-storage, diesel-storage backup, and DC-side parallel PV-storage-charging systems. The final topology, protection, transfer behavior, and equipment ratings must be verified for each project. For PV-side DC/DC input, see [LEONA-M200K 200 kW PV MPPT controller](/en/product/leona-m200k). Ask VGRID to check compatibility with the battery, PV array, generator, and site grid. DC interfaces, operating modes and project limits DC interfaces and split wall-mounted structure The wall-mounted LEONA-H135K uses separate converter and MPPT-controller units. The brochure lists IP65 protection and approximate unit weights of 85 kg (converter) and 60 kg (MPPT controller). DC terminals include BAT1 (+/−) for the battery and DC1/DC2 (+/−) reserved for the DC bus or project-selected PV/MPPT equipment. LOAD A/B/C/N is the AC load output; GEN is the grid connection, while DG is the diesel-generator connection. COM-1/COM-2 are communication interfaces. Terminal assignment and conductor sizing must follow the approved wiring diagram. Operating modes Documented control modes include PQ, VF, droop and VSG. Depending on the system design, the PCS can form an islanded AC bus, coordinate grid-connected operation, work with an AC-coupled PV inverter, or integrate a diesel generator. The brochure describes grid/generator transfer below 10 ms; confirm this value and the actual transfer arrangement against the approved configuration. Parallel designs include one-cluster/one-management and centralized battery management. Application boundaries This is a project-configured microgrid PCS, not a plug-and-play promise for every PV array, battery, generator or site grid. The MPPT controller is selected to match PV voltage/current and array design. Verify battery voltage and BMS protocol, PV operating window, generator capability, protection/selectivity, grounding, transfer logic, load step, parallel-unit limits and local code before ordering. The 600 kWp PV in the diagram is an example configuration, not a guaranteed maximum input rating. Solution diagrams from the LEONA-H135K brochure These six diagrams show example topologies. They illustrate possible system arrangements and are subject to project engineering validation.

It is a wall-mounted, split-architecture microgrid energy storage PCS. The supplied brochure lists 135 kVA rated off-grid output and IP65 protection. ### Can LEONA-H135K connect to PV and an existing PV inverter? The brochure describes direct PV interface options with separately selected MPPT equipment and AC-coupled integration with existing PV inverters. Confirm the array and inverter compatibility for the project. ### Can it work with a diesel generator? The brochure includes grid and generator connections and PV-storage-diesel and diesel-storage backup configurations. Generator ratings, transfer sequence and controls require project validation. ### Does LEONA-H135K support parallel operation? The brochure describes one-cluster/one-management and centralized parallel configurations, including SOC-based power adjustment. Confirm the permitted unit count and battery controls for the selected design. ### What is the rated output: 135 kW or 135 kVA? The supplied technical brochure states 135 kVA rated off-grid output and does not specify rated active power in kW. Confirm the kW rating against the approved datasheet before publishing a kW claim. ### What DC interfaces does the LEONA-H135K provide? The brochure identifies BAT1 (+/−) for the battery, DC1/DC2 (+/−) reserved for the DC bus or project-selected PV/MPPT equipment, and separate COM-1/COM-2 communication ports. LOAD A/B/C/N is AC output; GEN is the grid input and DG is the diesel-generator input. Confirm terminal use against the approved wiring diagram. ### Which operating modes and microgrid applications are supported? Documented modes include PQ, VF, droop and VSG. Example configurations include off-grid PV-storage-diesel, AC-coupled PV, grid/generator transfer, parallel battery clusters and PV-storage-charging. Final controls, transfer sequence and compatibility require project engineering. ### What should be checked before selecting a wall-mounted energy storage PCS? Check the mounting surface and clearances, IP65 installation conditions, battery voltage and BMS protocol, PV/MPPT voltage-current window, generator and grid ratings, wiring/protection, grounding, load steps and permitted parallel configuration. The brochure’s 600 kWp PV scheme is an example, not a guaranteed product limit. --- Request a quote: https://www.vgridpower.cn/en/contact?sku=LEONA-H135K
