I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration. So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.

A solar system health check covers your current system, what it can support, and which upgrades are worth considering for your situation. We assess compatibility, costs, and return on investment before you commit to anything.
Book a System Health CheckWhat's included in a health checkMy old solax packed in and was replaced by solar tech support. I am impressed at the very short time scale, sorted in only 3 days. Some were quoting 2-3 weeks. The old unit and all the packing was taken away.
When my GivEnergy battery started playing up it became basically useless and several companies I called said they couldn’t help. Solar Tech Support really knew their stuff, communicated very well and resolved the problem quickly. Without them I’d have had to buy a replacement battery.
Massively massively recommended. We had a big battery array (49kW across three phases) put in four years ago. c £35k cost. It’s been a total nightmare for many reasons, not least 1. our installer being totally useless and unresponsive and 2. Givenergy, our battery supplier, going bust. Long story short it had never worked anywhere near properly despite countless hours on phones and emails; the best we’d achieved was one third of the batteries working. Rather than write it off, I asked a PM friend to try to source someone who could come on site and review and revive the system. He found Solar Tech Support and Ron. Ron assured us he was the man to get it going again. After so many years of pain, I was not convinced but, true to his word, five hours later it was up and running. Lovely chap, super knowledgeable with a support team to lean on who are also clearly super technical. I honestly didn’t think there was much chance of getting this array going ever again so was absolutely delighted when Ron and team pulled it off. Bravo!
Absolutely amazing service. Ive had a couple of issues with my Givenergy system and couldn't manage to get in touch with Givenergy after they went bust. So I was searching on Google and came across Rons number. I sent Ron a WhatsApp message and got a prompt reply and he resolved the problem I had with my system. I can't recommend Ron enough its not often you get such a good service in this day and age. If you are experiencing issues with your solar system Ron is the man to contact.
Thank you for your diligence. On this occasion the battery was able to be saved but they have given a route to hopefully arrange a repair from the manufacturer.

Which upgrade suits your situation?
Use this quick decision guide to identify the most relevant upgrade for your system.
Your priority is adding battery storage. Read the add battery to existing solar guide — it covers AC coupling (works with any inverter), DC coupling (needs a hybrid inverter), compatibility, and realistic costs.
Adding a second or third battery module to an existing hybrid system is usually straightforward. Read the add extra battery guide to understand compatibility, installation, and costs. GivEnergy, Sunsynk, Growatt, and most other hybrid inverters support multi-battery configurations.
You need EPS (Emergency Power Supply) capability. There are four configuration types — from a simple EPS wall socket to full-house automatic changeover. Read the EPS installation page to compare options, check inverter compatibility, and see pricing from £495 (socket) to £995 (dedicated circuit).
Bird mesh is the standard solution — aluminium mesh fitted around the panel perimeter to prevent nesting. Read the bird mesh guide for what's involved, how long it takes, and typical costs.
Inverter replacement is common after 10–15 years or following irreparable failure. The inverter replacement card above covers what's involved for all major brands. GivEnergy owners can go directly to replacement GivEnergy inverters supplied and installed.
How STS handles upgrade work
We review your current system before recommending any upgrade. No upselling — only what your system can support and what genuinely makes financial sense.
All upgrade costs confirmed in writing before any work begins. Hardware, labour, DNO applications, and commissioning — no hidden extras.
Every upgrade is tested on-site and documented in a post-installation report. You leave with a clear record of what was done and how it was configured.
Independent from manufacturers and installers: STS is not tied to any solar brand, manufacturer, or supply chain. This means the upgrade recommendation is based entirely on what's right for your system — not what's most profitable for us to sell. We work with GivEnergy, Sunsynk, Growatt, SolarEdge, Solis, Huawei, Fox ESS, and all other major UK brands.
