Stop Guessing, Start Fixing Solar, Inverter, MPPT/PWM & Battery Troubleshooting Guide

Tired of guessing what's actually wrong with a solar or electrical system?

Every hour you spend guessing at a fault is an hour you're not billing. Every part you replace "just to be sure" is money straight out of your pocket. This guide fixes that.

Stop Guessing, Start Fixing is a field guide, not a textbook. No long theory chapters just 26 of the most common real-world faults you'll actually run into, each one broken down the same simple way:

✅ The symptom (exactly what you're seeing)

✅ The likely causes ranked by what's actually most common

✅ A step-by-step diagnosis sequence, so you know exactly what to test next

✅ The real fix

✅ A field note from an actual job showing how it played out

What's inside:

🔌 Part 1 Electrical faults (breaker trips, no power, flickering lights, nuisance RCD trips, phase imbalance)

☀️ Part 2 Solar PV array faults (low output strings, dead strings, ground faults, hot spots)

🔋 Part 3 Inverter faults (won't power on, grid fault codes, overheating, shutdowns)

🎛️ Part 4 Charge controller faults PWM & MPPT (not charging, low harvest, error codes)

🔋 Part 5 Battery faults (won't hold charge, BMS lockout, cell imbalance, swelling)

Plus 8 diagnostic diagrams built specifically to help you isolate faults visually fault trees, decision flows, and test-point diagrams, not just explanations.

💡 If you've ever replaced a part that turned out to be fine, or spent an hour on something that should've taken ten minutes this guide pays for itself the very first time you use it.
