Diagnostics & Repair
Solar system not working? We find out why.
An estimated 75% of solar systems across Africa have stopped working — most from configuration errors, not hardware failure. We diagnose the root cause, give you a written fault report, and fix the actual problem. Including systems installed by other companies.
Common problems we solve
Most solar problems in Uganda are fixable without expensive parts
The majority of faults we see are configuration or workmanship issues — not failed hardware. Wrong inverter settings, missing earthing, undersized cables, batteries that were never properly configured.
Wrong Inverter Settings
Charge voltages set to factory defaults instead of the battery spec. Cut-off voltages too low, killing battery cells. Generator start thresholds misconfigured. We audit every parameter.
Earthing & Grounding Faults
Missing earth connections, incorrect bonding, or no surge protection. Causes earth leakage trips, inverter shutdowns, and safety hazards. We test earth continuity and correct the installation.
Battery Degradation
Batteries dying faster than expected? Often caused by overcharging, deep discharge cycles, or wrong chemistry settings on the inverter — not the battery itself. We test cell health and identify the real cause.
Panels Underperforming
String misconfiguration, shading issues, dirty panels, or MPPT tracking errors. We measure string output against expected values and identify the shortfall.
Generator Integration
Generator not kicking in, ATS not switching, or the inverter fighting the generator. We configure the interaction between solar, battery, grid and generator properly.
Overheating & Cable Faults
Undersized cables, loose terminations, or poor ventilation causing overheating shutdowns. We inspect the full cable run and correct sizing, routing and termination quality.
Our diagnostic process
We find the cause before we touch anything
You get a written fault report with our findings and recommendations before any repair work begins. No surprises, no unnecessary replacements.
Book a Diagnostic →- 01Visual Inspection
Cable routing, termination quality, physical damage, ventilation, panel condition. We photograph everything for the report.
- 02Measurement & Testing
Voltage, current, earth continuity, battery state of health, PV string output. Numbers, not guesses.
- 03Settings Audit
Every inverter parameter checked against battery spec and usage pattern. Charge profiles, generator interaction, firmware version.
- 04Written Fault Report
You receive a written report: what we found, what caused it, and what we recommend. Before any repair work is authorised.
- 05Repair & Verification
We fix the cause, not the symptom. Post-repair testing confirms the system is performing correctly under load.
