Givenergy panels and battery had been offline for a couple of months after various changes by Givenergy to their app etc. Ron did a fantastic job of sorting it out - got things up and running almost immediately, followed by some fine tuning to get things fully configured. What a legend - great service, great comms, great result.
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!
Solar Tech Support answered my initial enquiry swiftly. They provided remote support to establish what the issue was, and through their experience and network, managed to get my clients system back online. Once the system was online, STS managed to diagnose the main issue to get the ac coupled inverter and battery back online, a battery repair was required. A site visit was organise and within a few days, the system was tested and back up and running. This has saved my client, and probably myself huge costs and inconvenience now the system is back online and working correctly. Would highly recommend.
My GivEnergy Solar/Inverter/Batteries system went down and the GivEnergy Administrators are totally non- existent/useless. Luckily, I found Ron, who used to be a GivEnergy Installer, and beyond my wildest dreams, he sorted everything out remotely from 200 miles away. His approach to everything is very professional and I cannot recommend him more highly. Thanks very much Ron!!
Roland is a true gentleman. He provided a refurbished inverter when my givenergy one failed. The install was a pain and took him hours. I was expecting a big bill but he honoured his price despite the extra effort. While here he diagnosed a battery fault. He helped me get the battery down and recommended an excellent company who could repair the battery. Absolute legend of a person and company
I contacted Solar Tech Support with an issuewith my solar and Ron went out of his way to help me. Despite the fact that I'm situated hundreds of miles away and he knew there'd be no business opportunity from my inquiry, Ron still chased solutions and helped me get an understanding of what I needed to do. I love working with people like this, people with integrity and service at the heart of what they do. I just wish hew was nearer!
The GivEnergy All-in-One integrates 13.5kWh of LiFePO₄ storage and the inverter in a single 173.7kg floor unit (181.3kg on AIO 2 + MPPT). The architecture differs by model: original AIO and AIO 3.6 are AC-coupled (cable in from an existing PV inverter); AIO 2 + MPPT is hybrid — solar panels connect directly to a dedicated MPPT module with six independent trackers.
On the original AIO and the AIO 3.6, backup needs a Gateway. With a Giv-Gateway they back up the whole home and keep charging from solar during the cut; without one they cannot supply the home in a power cut. The Gateway has been optional since 30 May 2024. Off-grid ratings per datasheets: original AIO = 6kW continuous / 7.2kW peak; AIO 3.6 = 3.6kW on-grid / 6kW continuous / 7.2kW peak off-grid; AIO 2 + MPPT = 12kVA continuous / 14.4kVA peak off-grid. Grid compliance (G98 vs G99) is set by the combined inverter output per phase on site, not battery capacity.
The original AC-coupled AIO — 13.5kWh of integrated LiFePO₄ storage and a 6kW continuous inverter (7.2kW peak). Connects via AC cable to an existing PV inverter's AC output.
Use case: retrofit onto an existing solar PV install. The 6kW continuous output suits homes that export at meaningful rates during sunny periods. Up to 6 in parallel for higher-capacity sites.
Same 13.5kWh storage, same chassis (173.7kg), but rated at 3.6kW on-grid output, within the G98 limit on its own; with existing solar on the same supply the total goes past 16A per phase, so it is G99. Off-grid the AIO 3.6 can deliver 6kW continuous and 7.2kW peak per datasheet.
Use case: properties where the DNO restricts on-grid output to 3.68kW per phase, or where the customer prefers a 3.6kW export setting. Off-grid capability is unchanged.
The AIO 2 inverter on its own is a 6/8/10/11/12kW configurable hybrid with 13.5kWh integrated storage; pair it with the GIV-MPP-20.0-G1 MPPT module for a hybrid system with six independent PV trackers and up to 20kW of PV input. The expansion battery (GIV-BAT-13.5-AIO2-E) adds another 13.5kWh in a 307V package — up to two of those, for a maxed-out 40.5kWh AIO 2 + MPPT system.
Six independent MPPT trackers — why it matters:
