Brilliant support to get my solar battery working again. I didn’t expect help on a Saturday but Ron answered the phone, listened and sent me the information I needed to get it going, answered questions etc. A brilliant service I’d happily recommend.

Ron was brilliant. He really tried to help. He spent hours trying to fix our GivEnergy AIO and ultimately it became apparent that it needed parts to fix the BMS management system. As there appears to be no replacement parts available on the market, he gave excellent advice on what options are now available to move forward. He is incredibly helpful and knowledgeable.

Big thanks to Ron. He was incredibly patient and helpful over the phone, taking the time to walk myself and the installer through every troubleshooting step. Through lots of testing he figured out the issue was definitely a hardware issue, which allows us to consider our next steps. Support fees are clear and they operate a “no fix no fee” policy. It is rare to find that kind of honesty combined with dedicated phone support nowadays. I highly recommend Ron, if you need help with your solar system don’t hesitate to give him a call.

A superb service from Ron who went beyond the normal service received from other Tech support companies. I live abroad and was badly let down when my givenergy system failed (and the company went bankrupt) and the local supplier ran away from the problem. Ron sorted the problem and even accessed specialist coding for the inverter that would not be available for suppliers. Ron also ran a full diagnostic to insure that all was in good working order afterwards. Without Rons support and patient assistance I doubt I would ever have got the system back up and running. Well done and thankyou and you have a customer for the future.

What's included

Root cause identification

We review your fault log, generation history, and live readings to pinpoint exactly what's wrong — not guess.

Settings validation

CT clamp direction, export limit, charge schedules, tariff configuration — corrected during the session where safe to do so remotely.

Written action plan

A clear written report of what was found, what was done, and any on-site work required — with an honest cost estimate if needed.

Follow-up path

If parts or a site visit are needed, you'll know exactly what they are before committing. No blank cheques.

How it works
01

Book and describe the fault

Fill in the booking form with what you're seeing — fault codes, lights, when it started. We'll confirm a time, usually the same day.

02

We connect and diagnose

During the 30-minute session we access your monitoring data and inverter readings, identify the fault, and apply any safe remote fixes.

03

Written report and next steps

You receive a written summary of what was found, what was done, and a clear recommendation — with honest costs if further work is needed.

When a remote diagnostic is the right choice

System producing less than expected but no obvious fault — likely a configuration or monitoring error

Battery not charging from solar or overnight — usually a CT clamp direction error or schedule misconfiguration

Monitoring app showing incorrect data, reversed import/export, or offline readings

Fault code on inverter or battery — we'll identify what it means and whether it needs a site visit

Export limit settings incorrect after DNO change or smart meter installation

Not sure what's wrong — start here before committing to an on-site visit

Safety note: If you smell burning, see arcing, or notice smoke or discolouration around your inverter or battery, isolate at the consumer unit immediately and call 999. Do not attempt to open any enclosures. For these situations use our emergency solar repair service.

What we check during a remote diagnostic

During your 30-minute session, we conduct a comprehensive review of your solar PV and battery system. Here's exactly what we examine:

Inverter fault logs and error history

We review every error code, warning, and fault recorded by your inverter, tracing patterns and identifying which ones need attention and which are normal transient events.

Generation data analysis

Daily, weekly, and monthly generation patterns are cross-referenced against weather, seasonal norms, and system specification to spot underperformance or anomalies.

Battery state of charge and cycling

We examine charge/discharge cycles, resting voltage, depth of discharge patterns, and state of health indicators to assess battery condition and usage patterns.

CT clamp configuration and direction

One of the most common faults — CT clamps installed backwards cause reversed import/export readings. We validate direction and orientation against live data.

Export limit and DNO compliance

We verify export limit settings match your DNO agreement, especially following smart meter installation or changes to grid connection terms.

Charge and discharge schedule review

Battery charging and export schedules are checked against your tariff, ensuring optimal alignment with off-peak rates and export pricing.

Firmware version and known issues

We check inverter and battery firmware versions against manufacturer known issues database, identifying whether updates or workarounds are needed.

Monitoring platform connectivity

We verify data accuracy between your inverter, monitoring app, and our platform, identifying communication gaps, data lag, or sensor failures.

Common faults we diagnose remotely

CT clamps installed backwards

This is one of the most frequent faults we encounter. When CT (current transformer) clamps are reversed, your system reports export as import and vice versa. Your battery may appear to be discharging when it's actually charging from solar, and your monitoring app shows backwards flow. We can confirm this with live data and walk you through the fix — usually a 5-minute correction that doesn't require an engineer visit.

Learn more about monitoring data accuracy issues →

Export limits set incorrectly

After smart meter installation or DNO agreement changes, export limits often remain at old settings. This can cap your system to 0 kW export, prevent battery discharge optimization, or breach your DNO agreement. We validate your settings against your current agreement and correct them remotely if needed.

Troubleshoot export limit problems →

Battery charge schedules not aligned with tariff

Your battery may be charging during peak hours when electricity is expensive, or discharging when prices are low. Misaligned schedules waste export revenue and increase grid import costs. We review your tariff and adjust charge/discharge windows to maximize savings remotely.

Fix battery charging issues →

Monitoring app showing reversed or incorrect data

Sometimes your app displays inverted import/export values, shows offline data despite the inverter being online, or reports generation figures that don't match live readings. We trace the data path from inverter through monitoring platform to your app and identify where the disconnect is occurring.

Resolve monitoring connectivity issues →

Inverter in standby mode due to grid frequency drift

Grid frequency fluctuations outside normal range (49.8–50.2 Hz) can cause your inverter to disconnect and enter standby. This usually resolves itself, but persistent standby indicates a grid issue or inverter sensitivity setting that needs validation. We check your settings and advise whether contact with your DNO is needed.

Check system performance and grid stability →

Battery not charging from solar due to mode misconfiguration

Your battery may be set to manual charge only, or configured to ignore solar surplus during certain hours. This prevents self-consumption and wastes potential savings. We review your operating mode and adjust schedules so your battery charges intelligently from available solar.

Get your battery charging again →

What happens after your diagnostic

Every diagnostic concludes with a clear next step. We don't leave customers with open questions or unclear paths forward. Here are the three most common outcomes:

✓ Fault resolved remotely

Most common for configuration issues. We correct CT clamp direction, export limits, charge schedules, or other settings during the session. You receive a written report documenting the changes and your system returns to normal performance — usually within the 30-minute session window.

No further action needed

→ On-site visit required

If physical work is needed — faulty hardware, physical installation errors, parts replacement — we tell you exactly what's required and the cost before you commit. On-site repairs start from £245, and parts are pre-ordered to ensure the visit is efficient and same-day completion where possible.

Clear quote, no surprises

⚠ Warranty claim recommended

If we identify a manufacturing defect or failure covered under warranty, we document the fault, prepare evidence, and provide all the documentation you need to file a claim with the manufacturer or installer. We handle warranty support at every step.

We provide all documentation

Nothing is wasted: Whether the fault is fixed remotely, requires a visit, or needs a warranty claim, the free remote diagnostic always translates into faster resolution, fewer wasted site visits, and honest costs upfront. We treat your time and budget with the same care we treat our own.

FAQ

Questions about the remote diagnostic

We connect to your inverter and monitoring system, review your generation history, fault log, and live readings. We identify the root cause of the fault, walk you through what we find, and apply any settings corrections that are safe to make remotely — CT clamp direction, export limits, charge schedules. You receive a written report summarising the fault, what was done, and any recommended next steps.
If on-site work is needed, we tell you exactly what is required and what it will cost before you commit. The remote diagnostic is free, so nothing is wasted — it means any engineer visit is precisely targeted, with the correct parts identified in advance. On-site solar system repairs start from £245.
All major brands: SolarEdge, GivEnergy, Sunsynk, Growatt, Solis, Enphase, Fronius, Fox ESS, Huawei, Tesla Powerwall, SiEnergy, AlphaESS, Sofar, and most others. If you are unsure whether your brand is supported, contact us before booking.
Yes, you'll need to be available during your booked 30-minute slot. We'll call at your scheduled time, walk you through what we're finding in real time, and may need you to check settings on your inverter or answer questions about how the system has been behaving. This interaction ensures we get the full picture and can make recommendations you understand and trust.
Yes, for most issues. We can review state of charge, cycling patterns, charge/discharge rates, firmware versions, and error logs to diagnose battery configuration and software faults. However, internal battery hardware defects (cell failure, BMS issues causing physical damage) require on-site inspection. We'll tell you which category your issue falls into and what comes next.
Have your inverter and battery brand/model ready — you'll find these on the physical units or in your installation paperwork. A clear description of what you're seeing (e.g., fault code, reversed import/export in app, battery not charging) helps us prepare. You don't need login credentials — we'll ask for monitoring platform access during the session, or you can grant temporary read-only permissions if your system allows it. If you have recent screenshots of error codes or unusual readings, keep those handy to share during the call.
