Hello, I’m George Alibinisis, a certified electronics engineer with over 10 years of hands-on experience in embedded systems and renewable energy hardware. My passion for sustainable technology led me to specialize in repairing critical components for photovoltaic (PV) systems. I’ve worked on hundreds of solar installations, focusing on high-reliability embedded cards that power the heart of modern inverters.

I understand the downtime costs and frustration when inverters fail – that’s why I offer fast, reliable, and cost-effective repair services tailored to Phytec embedded computer cards used in Refusol and Siemens PV inverters.

My workshop is equipped with state-of-the-art diagnostic tools, including oscilloscopes, JTAG debuggers, and thermal imaging for precise fault isolation. I prioritize eco-friendly repairs, extending the life of your equipment to support a greener future.

What I Offer: Repair Services: I provide comprehensive repair and maintenance for Phytec Single Board Computers (SBCs) and System-on-Modules (SOMs) integrated into Refusol and Siemens solar inverters. These embedded cards handle real-time control, data logging, and power optimization – when they fail, your entire PV system suffers.

My services include:

• Diagnostic Assessment:** Full teardown analysis to identify issues like firmware corruption, capacitor degradation, or connector failures. Initial diagnostics are free with repair commitment.
• Component-Level Repairs:** Replacement of faulty ICs, memory modules, or processors using genuine or equivalent Phytec-compatible parts. No “band-aid” fixes – I rebuild for longevity.
• Firmware Reflashing and Updates:** Restore or upgrade Phytec’s embedded Linux/RTOS firmware to ensure compatibility with modern PV standards.
• Testing and Certification:** Post-repair stress testing under simulated solar loads, with a detailed report confirming 98%+ efficiency recovery.
• Preventive Maintenance Packages:** Annual check-ups to catch issues early, including thermal paste refresh and dust mitigation for harsh outdoor environments.
• On-Site and Remote Support:** For urgent cases, I offer mobile repairs or remote diagnostics via secure VPN access.

Specialized in:

Flexgate Repair on MacBook
If your MacBook display goes dark when the lid opens past a certain angle or shows a “stage light” effect at the bottom, the backlight cable may be failing — a common issue known as flexgate. Apple no longer covers these repairs under warranty, often leaving owners with the only option of replacing the entire LCD at a steep cost. Instead, we carefully replace the damaged cable section under a microscope, restoring full display functionality without the expense of a new screen.

Wacom Tablet Repair
From broken USB ports and faulty power circuits to unresponsive touch or pen issues, professional Wacom tablets often fail after heavy use. We diagnose and repair these faults at the component level, extending the life of your tablet and getting you back to creating without costly replacements.

Phytec Embedded Card Repair
Industrial systems such as Refusol and Siemens inverters rely on Phytec embedded cards. When these fail, the entire system can stop operating. We specialize in repairing these cards through advanced diagnostics, component replacement, firmware reflashing, and stress testing — bringing equipment back online reliably and cost-effectively.

Why Choose My Services?

Phytec embedded cards, such as the phyCORE or phyBOARD series, are robust but prone to failures from heat, voltage spikes, or age in PV applications. Refusol (now under Advanced Energy) and Siemens inverters rely on these for seamless DC-to-AC conversion and grid synchronization. Common issues I fix include boot failures, communication errors with inverter firmware, and degraded performance in high-irradiance conditions.
