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 checkBrilliant 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.
Called back within a day and gave good advice.
Ron was extremely helpful and tried his best to repair/reset our GivEnergy inverter remotely. In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
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.

Keep your home running during a grid outage. Four configuration types from a single EPS socket to full-house automatic changeover.
Aluminium mesh fitted around the panel perimeter to stop pigeons, starlings, and squirrels nesting underneath your solar array.
Already have a hybrid inverter and battery? Add a second or third battery module to increase your storage capacity and reduce grid import further.
Inverter failed, out of warranty, or switching to a hybrid for battery compatibility? Replacement covers supply, installation, commissioning, and settings migration.
Have solar panels but no battery? This guide covers AC vs DC coupling, inverter compatibility, DNO requirements, CT clamp changes, and realistic costs for a full battery retrofit to an existing solar-only system.
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 £795 (socket) to £795 (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. Read the inverter replacement guide to understand what's involved. If you're ready to book, go directly to the inverter replacement service page.
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.
Compatibility assessment, generation review, and upgrade recommendations. Start here if you're unsure what your system needs.
Supply, fit, commission, and document a new inverter. All major brands. Cost confirmed before work begins.
Something broken rather than an upgrade? On-site fault diagnosis and repair for all major brands.
Not sure if you have a fault or just need an upgrade? A remote diagnostic identifies the root cause before you commit to anything.
A solar system health check covers your current system, identifies which upgrades are compatible, and gives you a clear, costed plan — no sales pressure, just engineering advice.
