Product details
Overview
STEVAL-ISV003V2 from STMicroelectronics is a 250 W plug-in photovoltaic microinverter demonstration board supporting 110–240 V AC, 60 Hz grid output, with 18–45 V DC input range, integrated MPPT via perturb-and-observe algorithm, and digital control implemented on an STM32 microcontroller.
For engineers reviewing the STEVAL-ISV003V2 datasheet, STEVAL-ISV003V2 pinout, STEVAL-ISV003V2 application, or STEVAL-ISV003V2 equivalent, this board enables rapid evaluation of grid-synchronized DC-AC conversion, real-time MPPT tuning, RS-232-based telemetry, and dual-mode (open/closed-loop) inverter control for residential solar panel integration.
Technical Context
The board implements a two-stage power architecture: a high-frequency isolated interleaved DC-DC boost stage stepping PV voltage to ~400 V DC, followed by a full-bridge DC-AC inverter with sinusoidal PWM generation. Control is fully digital using an STM32 MCU running proprietary grid synchronization firmware.
Grid synchronization employs decoupled active/reactive power control, while MPPT uses real-time perturb-and-observe logic. Operation supports both open-loop (lookup-table reference) and closed-loop (grid-voltage feedback) modes, with LED display for parameter monitoring and RS-232 for voltage/current telemetry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Power | 250 W continuous AC output - supports single-panel residential PV integration without external derating. |
| Input Voltage Range | 18–45 V DC - matches typical Voc/Imp range of commercial 60-cell and 72-cell plug-in PV modules. |
| Output Voltage/Frequency | 110–240 V AC, 60 Hz - compliant with North American and select Latin American utility interconnection standards. |
| MPPT Algorithm | Perturb-and-observe (P&O) - dynamically tracks maximum power point under varying irradiance and temperature conditions. |
| Control Core | STM32 32-bit microcontroller - executes real-time grid sync, MPPT, protection, and communication tasks in single-chip solution. |
| Communication Interface | RS-232 - enables serial readout of real-time AC voltage, current, and DC input parameters for system diagnostics. |

FAQ
Is STEVAL-ISV003V2 certified for grid connection?
No - it is a demonstration board intended for lab evaluation and algorithm validation only. It lacks UL 1741, IEEE 1547, or EN 50530 certification. Users must integrate its design into a fully certified system for field deployment.
What is the role of the STM32 microcontroller on this board?
The STM32 executes all real-time control functions: MPPT calculation, grid-synchronization phase-locking, PWM signal generation for both DC-DC and DC-AC stages, fault detection, LED interface management, and RS-232 telemetry packet formatting.
Does STEVAL-ISV003V2 support 50 Hz operation?
No - this is the 60 Hz version only, as explicitly stated in the product title and data brief. ST does not list a 50 Hz variant under this part number; separate hardware or firmware modification would be required.
Can the LED display be reprogrammed or customized?
The LED interface is hardwired to the STM32 GPIOs and driven by factory firmware. While the source code is not publicly distributed, ST provides reference firmware examples for the STM32 platform that can be adapted to modify display behavior using standard STM32Cube tools.
