The Mendaz 24/7 Repair Clinic Advantage

System downtime means lost savings or halted business operations. Our Repair Clinic is our commitment to minimising that risk.

Fast, Local Solar Inverter Repair

Our technicians are highly skilled in diagnosing and repairing major global inverter brands (Sunsynk, Victron, Deye, etc.), as well as specialized off-grid units. Since we are locally based, we offer faster turnaround times than installers who rely on external agents or manufacturer repairs overseas
  • Specialty: Expertise in both hybrid inverters and high-capacity commercial three- phase units.
  • Service: Diagnostics, component-level repair, firmware updates, and safety testing.

Battery Diagnostics and Refurbishment

Our deep knowledge from lithium battery storage manufacturing allows us to provide specialized diagnostic and refurbishment services for battery banks, often extending their useful life and preventing unnecessary replacement costs.
  • Focus: State-of-Health (SOH) testing, balancing, and module replacement.

Comprehensive Solar Maintenance Services

Our service covers every aspect of solar design and installation, from ensuring technical precision to creating visual harmony that fits your space. We aim to deliver not just clean energy, but a seamless experience that feels reliable, natural, and made to last for years.

01

Annual Performance Optimization Check

Our comprehensive annual service ensures your system is producing the maximum possible power. This includes:
  • Yield Analysis: Comparing current performance against design specifications and historical data.
  • Shading & Soiling Assessment: Identifying new factors impacting output.
  • Inverter Log Review: Diagnosing potential long-term component stressors and issues.

02

Panel Cleaning and Inspection

Dirt, dust, and environmental debris can reduce panel efficiency by up to $20\%$. Our professional cleaning service uses specialized, non-abrasive methods to restore maximum yield. We also conduct physical inspections for micro-cracks, corrosion, and structural integrity.

03

Electrical Safety and Compliance Audit

We verify all wiring, earthing, bonding, and protective devices (like our manufactured combiner boxes) remain fully compliant with the original Certificate of Compliance (CoC) and current City of Cape Town regulations. This is vital for insurance and personal safety.

Why In-House Expertise Matters for Service

When you choose Mendaz Solar for maintenance, you benefit from our full vertical integration:
  • Manufacturing Insight: We train our service technicians on the architecture of our own manufactured components, giving them unparalleled insight into system failures and diagnostic speed.
  • Immediate Parts Access: We maintain a large inventory of spare parts and components due to our distribution status, ensuring fast replacement when necessary.
  • Technical Authority: Your system is supported by the same Registered Master Electricians and engineers who handle our initial installations and compliance submissions.
