When Your Solar Power System Develops a Fault, We Are One Call Away.

A well-installed solar system is built to last — but like any technical system, faults can occasionally occur. Inverters can trip. Batteries can underperform. Connections can loosen.

Panels can sustain physical damage. When any of these things happen, the last thing you need is to be left waiting for days without power or chasing a contractor who is difficult to reach.

At Buffalo Energy Solutions, our technical team is available to diagnose and resolve faults on any system we have installed — and in many cases, on systems installed by other providers as well. We carry spare parts for the products we supply, and we work with a clear focus on resolving issues as quickly and efficiently as possible.

 

Our Approach to Repairs & Troubleshooting

We do not guess. We do not apply temporary fixes that mask a deeper problem. And we do not recommend replacements when a repair will do the job properly.

When you report a fault to us, our team follows a structured diagnostic process to identify the root cause of the issue before any repair work begins. This ensures that the solution we provide actually resolves the problem — not just the symptom.

Every repair carried out by our team is documented, and where replacement parts are used, they are sourced from the same verified suppliers we use for our installations. You will never receive a substandard or unverified component as part of a repair on your system.

 
Common Faults We Diagnose & Resolve

Our technical team has experience diagnosing and resolving a wide range of solar system faults including:

 

🔌 Inverter Faults
  • Inverter tripping or shutting down unexpectedly
  • Error codes and fault alerts on the inverter display
  • Inverter not switching between power sources correctly
  • Inverter overheating or making unusual sounds
  • Inverter not charging batteries from solar or grid
  • Complete inverter failure
 
🔋 Battery Issues
  • Batteries not holding charge or draining too quickly
  • Battery bank not reaching full charge
  • Individual batteries failing within a bank
  • Battery management system (BMS) faults and alerts
  • Swollen, leaking, or physically damaged batteries
  • Battery voltage imbalance across a bank
 
☀️ Solar Panel Problems
  • Panels producing significantly less power than expected
  • Physical damage from impact, hail, or falling objects
  • Hotspots identified during thermal inspection
  • Delamination or discolouration of panel surfaces
  • Broken or damaged MC4 connectors and junction boxes
  • Partial shading issues affecting string performance
 
🔧 Electrical & Wiring Faults
  • Loose or corroded electrical connections
  • Blown fuses or tripped circuit breakers
  • Damaged or degraded DC and AC cables
  • Faulty isolators or surge protection devices
  • Earthing faults and insulation resistance failures
  • Distribution board issues related to the solar connection
📱 Monitoring & Communication Faults
  • Monitoring app not displaying live data
  • System not communicating with the monitoring platform
  • Incorrect readings or data gaps in the monitoring history
  • Wi-Fi or communication module faults
Our 4-Part Repairs & Troubleshooting Process

Here is exactly what happens from the moment you report a fault to the moment your system is back to full operation.

 
✅ Part 1: Fault Reporting & Remote Diagnosis

When you contact us, our technical team begins the diagnostic process immediately. We access your system’s monitoring data remotely, discuss what you are experiencing, and in some cases resolve the fault without a site visit. Where a visit is required, we schedule one promptly.

What this means for you: The diagnostic process begins the moment you call — not when we eventually arrive on site.

 
✅ Part 2: On-Site Fault Diagnosis

Our technician arrives with the tools, testing equipment, and spare parts relevant to the fault reported. We carry out a thorough inspection of all components — inverter, batteries, panels, wiring, and protection devices — and document our findings before any repair work begins.

What this means for you: We identify the root cause of the fault, not just the visible symptom — so the repair resolves the problem properly.

 
✅ Part 3: Repair & Component Replacement

We carry out the necessary repair using parts sourced from our verified suppliers. If a part needs to be ordered, we communicate this clearly and provide a realistic timeline. Where possible, we implement a temporary measure to restore partial system function in the interim.

What this means for you: Your system is repaired with quality parts to a professional standard — not patched up with whatever is available.

 
✅ Part 4: Post-Repair Testing & Documentation

Once the repair is complete, we test the full system to confirm the fault has been resolved and all components are operating correctly. A written repair report documenting the fault, the work carried out, and any parts replaced is provided to you and filed in your customer record.

What this means for you: You have written confirmation of exactly what was wrong, what was done to fix it, and the current condition of your system.

 
 
Our Spare Parts Availability

We maintain a stock of spare parts for the core products we supply and install. This includes:

  • ✅ Inverter replacement components and modules
  • ✅ Lithium and gel battery units
  • ✅ MC4 connectors and junction boxes
  • ✅ DC and AC fuses and circuit breakers
  • ✅ Surge protection devices
  • ✅ Isolator switches
  • ✅ Solar cables and connectors
  • ✅ Monitoring and communication modules

Holding spare parts in stock means we can resolve the majority of common faults without the delays that come with waiting for parts to be ordered and shipped.

 
Repairs on Systems We Did Not Install

We also provide repair and troubleshooting services for solar systems that were installed by other providers. If your system was installed by a company that is no longer available to support it, or if you have been unable to get a satisfactory response from your original installer, our team can carry out a full diagnostic assessment and carry out the necessary repairs.

In these cases, we begin with a comprehensive system inspection to understand how the system was built, identify any installation issues that may be contributing to the fault, and provide you with an honest assessment of the work required.

 
Turnaround Time

We understand that a faulty solar system is not a minor inconvenience — for many of our customers, it means a return to generator dependency and all the costs and disruptions that come with it. We treat every repair request with urgency.
