## LEONA-B750K vs LEONA-H135K: choosing between 750 kVA cabinet and 135 kVA wall-mount units

Both split hybrid inverters share the same VSG grid-forming core, PQ/VF/droop modes and LEONA-M200K MPPT platform, yet they differ in power class, battery voltage window, isolation and installation. The B750K is a 750/825 kVA IP54 floor cabinet with a built-in Znyn0 transformer; the H135K is a 135/148.5 kVA IP65 wall unit of about 85 kg. Start with the continuous load, the battery cluster voltage and the site lifting conditions.

## Three paradigm shifts in microgrid inverters: off-grid, seamless transfer and always grid-forming

The VGRID POWER technical library divides microgrid inverter evolution into three stages: a simple off-grid inverter, a dual-mode inverter with seamless on/off-grid transfer, and a grid-forming inverter that always behaves as a voltage source. This is not merely a reduction of transfer time from hundreds of milliseconds to 10 ms; the dividing line is whether the control structure changes abruptly. In always grid-forming operation, grid-connected and islanded are only connection states, not operating modes.

## AEMS100 fast commissioning: from power-up checks to the nine configuration items

The VGRID POWER AEMS100 quick-commissioning guide starts with wiring: verify the 5 V supply of AEMS100 and SP30HBG2, PCS communications, battery-cluster communications and the WiFi/4G module before touching parameters. A missing link makes later configuration pages unreadable. Once the screen returns to the home page, configure the project items one by one and read back the key variables.

## Selecting the LEONA-M200K MPPT: 200 kW, 16 inputs and a 200-900 V tracking window

The LEONA-M200K is the external MPPT controller shared by the B750K and H135K: 200 kW rated, 200-1000 V PV open-circuit, 200-900 V MPPT range, 16 PV inputs across 8 MPPT channels and 99.26% peak efficiency. It decouples PV voltage from battery voltage and can be mounted near the array to shorten DC cabling. Check string temperature correction, input current and the high-voltage bus range together.

## What counts as genuine grid-forming: four verifiable criteria

Being able to run in island mode does not make an inverter grid-forming. The VGRID POWER technical library gives four criteria: permanent voltage-source behaviour, virtual inertia and damping, communication-free paralleling, and flexible interconnection of microgrids. Each can be turned into a tender clause and a site test, preventing a dual-mode inverter from being purchased as a grid-forming unit.

URL: https://www.vgridpower.com/en/blog/true-grid-forming-four-criteria

## AEMS100 battery communication checks: SOC, current sign and cluster management

The easiest step to skip in the AEMS100 guide, and the one that hides the most risk, is returning to the home page to confirm EMS/BMS data: whether SOC matches the BMS backend and whether battery current direction is correct. The guide states that AEMS100 treats discharge as positive and charge as negative, and the EMS strategy depends directly on that sign. A reversed sign makes SOC appear to fall while charging and can start the genset at the wrong time.

## Reading the LEONA-B375K single-line diagram: 3 x 125 kW, a 400 kVA transformer and one-cluster-one-management

The LEONA-B375K IP54 cabinet integrates three SP125HCPS 125 kW converters, a 400 kVA isolation transformer, an STS, DC busbars, the EMS and every breaker in one enclosure. The system is rated 375 kW at 400 V/50 Hz with transfer below 20 ms. The point of the single-line diagram is not summing power ratings but seeing where battery clusters, breaker numbers and critical loads attach to the bus.

## From SSG to VSG and Synchronverter: twenty years of grid-forming control

Grid-forming is not a recent feature but twenty years of accumulated research and field work: the IEEE task force proposed the Static Synchronous Generator in 1997, VISMA and VSYNC defined the VSG almost simultaneously in 2007, the Synchronverter embedded a full synchronous-machine model in 2008-2009, companies such as SMA brought it into real microgrids after 2010, and State Grid listed virtual synchronous machines among its ten key innovation programmes in 2016.

## Modbus RTU between PCS and EMS: frames, function codes and register partitions

The VGRID POWER event-record and shutdown-waveform protocol governs PCS-to-EMS communication over Modbus RTU or Modbus TCP/IP, covering SP100HC, SP100HC-1, SP110HS and SP110HS-1. The most common integration error is not wiring but reading across register partitions in a single request: the protocol explicitly states that cross-partition reads are not supported.

URL: https://www.vgridpower.com/en/blog/pcs-modbus-rtu-register-map

## Choosing a built-in isolation transformer: Znyn0, neutral and critical-load supply

The LEONA-B750K carries a Znyn0 isolation transformer, the LEONA-B375K single-line diagram places a 400 kVA transformer TR between the AC bus and the STS, while the LEONA-H135K uses a lightweight wall-mount design without one. Isolation is not only about noise: it decides whether the neutral is independent, whether poor site earthing is tolerable, and which bus section feeds critical loads during transfer.

URL: https://www.vgridpower.com/en/blog/isolation-transformer-znyn0-choice

## Where virtual inertia and damping come from: understanding VSG through the swing equation

VSG is not a deliberately sluggish ramp added to an inverter; it is a synchronous generator simulated inside a digital controller. Virtual inertia corresponds to rotor inertia, virtual damping to damper windings, active power-frequency droop to the governor and reactive power-voltage droop to the excitation regulator. Once that mapping is clear, frequency rate-of-change and recovery time under a load step become readable.

## Exporting event records and shutdown waveforms: registers 51005 / 51006 / 51007 to 53501-55601

Appendix 2 of the PCS event and shutdown-waveform protocol defines a four-step read: write 51006 for the start index, write 51007 for the record count, write 0xBB to 51005 to refresh the data, then read registers 53501-55601. It answers why a unit shut down and what happened at a failed transfer far better than a panel fault code alone.

URL: https://www.vgridpower.com/en/blog/fault-waveform-export-51005

## Topology choices for retrofit PV: AC coupling, DC-side paralleling and online-UPS schemes

Both the LEONA-B750K and LEONA-H135K explicitly support AC coupling to existing PV inverters and also document DC-side PV-storage-diesel-charging schemes, one-cluster-one-management DC coupling and online-UPS microgrids. The decision is not about which topology is newer but about whether the legacy inverters stay, where the genset and chargers connect, and which unit establishes voltage during an outage.

## Three open problems for grid-forming microgrids: LVRT, short-circuit capacity and weak-grid SCR

As grid-forming inverters move from microgrids into utility networks the demands rise sharply: voltage-source behaviour conflicts with low-voltage ride-through, power semiconductors limit fault current to 1.1-1.5 times rating (2-3 times in special designs) against 5-10 times for a synchronous machine, and falling short-circuit ratio raises multi-unit interaction and optimal penetration questions. The technical library lists these as the next barriers to break.

## LEONA-B375K field wiring and acceptance: breakers, SPDs, earthing and EMS links

The LEONA-B375K single-line diagram (V1.0, 2026-10-19) integrates three SP125HCPS converters, a 400 kVA isolation transformer, an STS, DC busbars, the EMS and breakers QF1-QF8 in one IP54 cabinet. Site work is not redesign but checking every breaker number, surge device, earth bar and the four EMS communication paths against the drawing, then verifying sub-20 ms transfer with waveform records.
