Vigdu Technologies

What Vigdu Technologies does

Vigdu Technologies is an Israel-based solar power electronics company that designs, manufactures, and markets photovoltaic optimization hardware for commercial, industrial, utility-scale, and residential PV plants. The company was founded in 2014 in Lod, Israel, by Evsei Berman (CEO, formerly VP App Dev & Customer Support at Telrad Networks), Ilya Nemenman (CTO/VP R&D, formerly head of R&D at Tigo Energy), and the late Doron Rabinovitch; the current executive team also includes EVP Sales & Marketing Avihu Bergman (ex-Raycatch, ECI Telecom) and Chief Software Architect Dr. Lev Kempner (ex-Telrad Networks).

Vigdu's product portfolio centers on two complementary technologies. SolarJet® is an inverter-agnostic multi-string DC/DC optimizer installed at the combiner box level that isolates each string and provides independent Maximum Power Point Tracking (MPPT) in real time, with claimed efficiency of 99.9% and built-in string-level monitoring, leakage detection, and optional rapid shutdown. Vigdu-PR is a fully analog, IP65-rated anti-PID solution that operates at night to prevent and recover Potential-Induced Degradation damage; it ships in three scaled models — PR1.x for systems up to 500kW, PR15.xx for commercial/industrial systems up to 1MW, and PR25.xx for utility-scale central inverters up to 4MW. Both product families carry EMC EN 61326-1 (2013) and Safety EN 61010-1 (2010) certifications.

The business model is built on two revenue streams: direct enterprise hardware sales to commercial, industrial, and utility-scale PV plant operators globally (quote-based, multi-year contracts), and OEM/embedded licensing under which Vigdu-PR has been deployed as a built-in solution by numerous central inverter manufacturers. The firm is privately held and founder-owned, with 11–50 employees and no disclosed institutional capital or revenue figures.

Core offering

Vigdu Technologies designs, manufactures, and sells photovoltaic optimization hardware for solar plants. Its flagship SolarJet® is an inverter-agnostic, plug-and-play multi-string DC/DC optimizer installed at the combiner-box level that performs independent real-time Maximum Power Point Tracking (MPPT) per string at 99.9% efficiency, eliminating string-mismatch losses. Its Vigdu-PR line is a fully analog anti-PID (Potential Induced Degradation) prevention and recovery system, available in PR1.x (≤500kW), PR15.xx (≤1MW), and PR25.xx (≤4MW) models for small/medium, commercial & industrial, and utility-scale systems respectively.

Product overview

Vigdu Technologies offers a two-product portfolio focused on photovoltaic plant optimization: SolarJet® is an inverter-agnostic multi-string optimizer that solves string mismatch problems through independent MPPT for each string, while Vigdu-PR is an anti-PID (Potential-Induced Degradation) solution that prevents, corrects, and reverses PID damage at night. Both products work together to maximize solar energy yield and ROI over the lifetime of PV plants. Vigdu-PR is available in three models (PR1.x for small/medium systems up to 500kW, PR15.xx for commercial/industrial systems up to 1MW, and PR25.xx for utility-scale systems up to 4MW) to address different system sizes.

Direct peers

• Enphase Energy: Enphase is the leading microinverter manufacturer and the broader MLPE category leader. While microinverters are a different topology, Enphase competes for the same C&I and residential customer wallet share on per-module PV optimization.
• Alencon Systems: Alencon Systems manufactures DC-DC optimizers and PID-recovery solutions for PV plants, including utility-scale central inverter applications. It is the most direct US competitor across both product lines Vigdu offers.
• SolarEdge Technologies: SolarEdge is the dominant MLPE (module-level power electronics) company with its optimizer-plus-inverter architecture. It competes directly with SolarJet® in string optimization, though SolarEdge's solution is inverter-coupled rather than inverter-agnostic.
• Tigo Energy: Tigo Energy is the originator of module-level DC power optimization for PV and a direct competitor to SolarJet®. Vigdu's co-founder/CTO previously led Tigo R&D, making this the most direct peer for technology and customer overlap.
• Ampt: Ampt produces DC string optimizers for commercial and utility-scale PV plants that maximize energy yield and reduce cost, competing directly with SolarJet®'s multi-string optimizer value proposition at the combiner box level.

Broad incumbents

• SMA Solar Technology: SMA is one of the world's largest PV inverter manufacturers and offers string-level monitoring and optimization features integrated into its inverters - a broad incumbent competing with SolarJet® at the system-architecture level.
• Huawei Digital Power (FusionSolar): Huawei's FusionSolar line includes smart PV optimizers and central inverters with built-in PID/recovery features, making it both an OEM-embedding threat to Vigdu-PR and an optimizer competitor to SolarJet® at utility scale.
• Sungrow Power Supply: Sungrow is a leading global central inverter manufacturer with built-in anti-PID functionality, directly competing with Vigdu-PR's OEM-embedded use case as well as standalone deployment.
• FIMER: FIMER (formerly ABB solar inverters) is a global PV inverter manufacturer serving C&I and utility-scale customers, with smart features overlapping Vigdu's optimization value proposition at the inverter level.

Regional players

• Kostal Solar Electric: Kostal is a European-headquartered inverter manufacturer with string inverter and optimizer offerings serving C&I markets in Europe, overlapping with Vigdu's geographic focus and OEM partner channel.
