The UK’s Solar Diagnostics & Recovery specialists
When your solar stops performing, shows faults, drains batteries, or simply doesn’t feel right — you don’t need sales. You need clarity. You need engineering.
Safety: no covers removed. No live work. If there’s burning smell, heat damage, or visible arcing, stop and isolate the system safely.

The First Light of Clarity in Solar
In Greek mythology, Alectrona is the goddess of the sun’s first light — the moment darkness lifts and everything becomes visible. That’s what we bring to solar systems.
When your system stops performing, shows faults, drains batteries, or simply doesn’t feel right — you don’t need sales. You need clarity. You need engineering.
Alectrona is a UK-based, engineering-led solar diagnostics and recovery specialist. We identify faults. We uncover underperformance. We restore systems to the output they were designed to deliver.
You invested in the sun. We make sure it works for you.

- ✓ Root cause + options
- ✓ Configuration validation (where safe)
- ✓ Written engineer summary
System Recovery
Installer gone bust, access locked, ownership transfer, documentation rebuild, baseline configuration.
- ✓ Portal/access recovery plan
- ✓ Handover pack + remediation plan
- ✓ Warranty evidence support
On-site Technical Visit
Hardware faults, isolation issues, CT rewires, EPS/backup circuit verification, independent inspections.

- ✓ Clear repair plan
Solar repair, diagnostics & system recovery (UK)
If you’re searching for solar inverter repair, battery not charging, monitoring offline, SolarEdge fault codes, Huawei FusionSolar support, Sunsynk CT clamp, GivEnergy red light or grid overvoltage trips, Alectrona is built for this exact moment: when you need clarity and an evidence-led plan.
We treat your system as a measurement chain (sensors → inverter → battery → portal → grid interaction) so the real issue is identified, not guessed.
Common problems we diagnose
High-intent symptoms people search for. If one matches your situation, there’s usually a repeatable fault path.
Hard stops: shutdowns, trips, fault states, no output, no comms.
Charge windows, CT logic, BMS limits, firmware, comms.
WiFi/LAN issues, portal lockouts, logger re-binding.
Evidence packs, export limiting checks, DNO escalation.
Inverted graphs, “nonsense” data, backwards battery behaviour.
Wrong caps, misreads, external meter/limiter conflicts.
Fault codes, comms errors, firmware mismatch, protection states.
Access recovery, handover packs, warranty evidence support.
Pricing
Clear pricing for diagnosis and recovery work. If we can solve it remotely, we aim to.
Evidence review + structured diagnosis path + written action plan.
- ✓ 30–45 min engineer call
- ✓ Fault path + next steps
- ✓ Written summary
Access recovery, ownership transfer guidance, and a clean handover pack.
- ✓ Ownership/access strategy
- ✓ Remediation plan
- ✓ Warranty evidence support
For confirmed physical checks: CT rewires, isolation faults, EPS circuits, hardware issues.
- ✓ Targeted site checks
- ✓ Safety-focused report
- ✓ Fix options
Remote-first: if the fastest safe route is remote, we’ll take it.
FAQs
Calm answers, straight from the engineering process.
Can you fix my solar system remotely?
Often, yes. We start remote-first using monitoring data, settings review and evidence-led troubleshooting. If on-site work is required, we’ll confirm exactly what needs checking before you pay for a visit.
My installer has gone bust — can you recover monitoring access?
Often. We guide the ownership transfer steps where supported, compile proof-of-ownership and commissioning details, and create a clean handover pack so you’re not dependent on the original installer.
Will you ask me to open my inverter or battery?
No. We don’t ask homeowners to open covers or do live electrical work. We focus on evidence, safe checks, and clear guidance.
Why does my app show wrong import/export?
Usually CT polarity, wiring configuration, or inverter interpretation. A reversed or misconfigured CT can flip the logic and cause strange battery behaviour. We validate the measurement chain and confirm with live readings.
