My GivEnergy hybrid inverter + battery system had worked faultlessly for 3 years when it suddenly stopped charging and discharging the battery. On contacting my supplier, who had used a sub-contractor for the installation work, I was provided with an email address at GivEnergy but, as it turned out, this is only for GivEnergy Software who are not able to assist. A Google search led to the Solar Tech Support web site, which contains a wealth of helpful information. I requested a remote solar diagnostic, and after providing Ron access to my inverter, he was able to identify and fix the problem within minutes. I am very impressed by Ron’s expertise and knowledge, which included useful information on the current state of GivEnergy Ltd. I would thoroughly recommend Solar Tech Support.

Book replacementDiagnose first — free if we can't fixMy Givenergy battery stopped working nearly a month ago. After unsuccessfully reaching out to my installer, who looks like he's also busted, I found Solar Tech Support on a Google search. They fixed my issue in a couple of hours. Any frustrated Givenergy customers, I highly recommend these guys.
Excellent service from Solar Tech Support. Extremely quick to respond, easy to deal with and clearly very talented engineers. They were persistent throughout a complex GivEnergy battery issue and resolved everything completely. Highly knowledgeable, professional and reassuring support from start to finish. Highly recommended.
I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.
Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.
Excellent response to diagnose a problem on our SolarEdge installation. Kept us informed at every step. Diagnosis quickly completed and solution implemented.

Hardware and labour quoted separately. All costs confirmed in writing before work starts.
Safe isolation of DC strings, AC supply, and battery (if present). Disconnection and removal of the old inverter. Responsible disposal — we take it away. All connection points documented before disconnection.
Replacement inverter supplied and sourced from authorised distributors. Mounted, earthed, DC strings reconnected with polarity verified. AC connection made including new MCB/RCBO if required. All connections to manufacturer specification.
Commissioned to UK G99 parameters. Export limit set. Monitoring account created or migrated from old serial number. Battery parameters configured (timed charge windows, SOC, tariff schedule) if applicable. EPS re-enabled if previously active.
G99 variation form submitted to your DNO on your behalf. Covers the change of generation equipment. Includes reference number in post-installation report. No extra charge — included in the service.
Full generation test on-site. Battery charge/discharge test if applicable. EPS function test if EPS circuit present. System confirmed operational before engineer leaves site.
Written report documenting: new inverter model and serial number, configuration settings, test results, monitoring portal details, and DNO notification reference. Keeps a permanent record for warranty, insurance, and future reference.
What is not included by default: If upgrading to a hybrid inverter and adding a battery at the same time, the battery hardware and connection are a separate line item quoted alongside the inverter replacement. EPS circuit wiring (if not previously installed) is also quoted separately — see the EPS installation guide. Everything is itemised in the written quote before work begins.

How an inverter replacement works — step by step
Submit details of your system (inverter brand, model, fault description, panel count). If any uncertainty about whether the inverter is truly faulty, we carry out a remote diagnostic first. We confirm the correct replacement specification and provide a written quote covering all costs.
You receive a written quote before any work begins. It covers: replacement unit cost (hardware), installation labour, commissioning, DNO G99 variation, and any additional components. Once you approve the quote, we order the hardware and schedule the installation date.
Engineer arrives on the agreed date. Old inverter safely disconnected and removed. New inverter mounted, all connections made to specification. Commissioned to UK G99 parameters. Monitoring portal configured. Battery reconnected and configured if applicable. Full test carried out before sign-off.
Post-installation report provided with all settings, test results, and new inverter details. G99 variation form submitted to your DNO — you receive the reference number in the report. You leave with a complete record of the replacement and a system that's fully documented for insurance and future reference.
Combine replacement with a battery upgrade
If your current inverter is a string model (no battery capability), replacing it with a hybrid model opens the door to battery storage in the same job or as a follow-on. This is often the most cost-effective approach — one scaffold hire, one electrical installation, one DNO application.
We can quote the inverter replacement and battery installation together as a package, or separately if you want to phase the investment. Both jobs are assessed and quoted in writing before any commitment.
