Expert Diagnosis & Rectification

Common Solar Breakdown Issues We Resolve

Every day your solar system remains non-operational is money wasted on utility grid bills. We identify root causes accurately rather than applying temporary patches.

Zero Generation / Sudden Output Drop

Diagnosing blown DC fuses, tripped Miniature Circuit Breakers (MCBs), severed string cabling, or failed bypass diodes in module junction boxes.

Low Insulation / Earth Leakage (Riso Fault)

Tracing moisture ingress in cracked DC cables, degraded conduits, or waterlogged MC4 connectors using high-voltage insulation megohmmeter testing.

Burnt MC4 Connectors & Lugs

Fixing poorly crimped or mismatched multi-contact connectors that generate high contact resistance, arc sparks, and melted terminal junction boxes.

Surge Protection Device (SPD) Failure

Replacing burnt Type-II DC and AC surge arrestors after high-voltage lightning strikes, restoring proper spike suppression to protect sensitive inverter electronics.

Chemical Earthing Pit Degradation

Re-treating dried or depleted earthing pits with Marconite / Bentonite conductive chemical compounds to drive resistance back down below 5.0 ohms.

Structural Wind Damage & Loose Mounts

Realignment of tilted solar superstructures, replacing rusted fasteners with SS304 hardware, and retrofitting civil concrete ballast blocks following monsoons.

Advanced Diagnostic Equipment We Deploy On-Site

We don't guess. We locate defects with precision calibrated testing instruments:

Infrared (IR) Thermography

FLIR thermal imaging cameras detect invisible microscopic hot spots, bypass diode failures, and loose high-resistance junction lugs instantly.

Digital Insulation Megger (1000V)

Applies up to 1000V DC across positive/negative string poles to earth to accurately pinpoint underground and conduit cable sheath leaks.

I-V Curve Tracer

Measures current-voltage characteristics of each individual string, comparing actual yield curves against STC factory curves to detect cell degradation.

4-Terminal Earth Tester

Measures true earth electrode impedance using Wenner / fall-of-potential methods to verify safety and lightning arrestor grounding.

Frequently Asked Questions

Why has my solar system generation dropped suddenly by half?

A sudden 50% drop typically indicates an open circuit on one of your two DC strings (due to a blown DC fuse, tripped DC breaker, or rodent damage), a failed MPPT tracking channel inside the inverter, or bypass diode failure in multiple modules.

What causes an 'Isolation Fault' or 'Riso Low' error on my solar inverter?

An isolation fault occurs when moisture penetrates damaged cable insulation or unsealed MC4 connectors, allowing small DC leakage currents to flow to earth. For safety, the inverter refuses to sync until the damaged cable segment is located and sealed.

What if my inverter is completely dead with no display lights?

Check our dedicated Solar Inverter Repair Services in Pune. We troubleshoot AC grid synchronization, blown internal bridge fuses, and IGBT power board failures for Growatt, Sungrow, Solis, and Fronius inverters.

Can you repair physical damage caused by storms or monsoons?

Yes. We safely replace shattered photovoltaic glass modules, realign twisted hot-dip galvanized mounting structures, re-anchor civil foundation footings, and verify structural wind-load tolerances.
