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.
When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.
Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them
Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)
Contacted Ron with a problem and he sorted it out quickly with no problems at all. Very knowledgeable on anything solar/ batteries. I would recommend him to anyone
I've spoken to Ron a couple of times with issues with my Givenergy installation. Such a friendly knowledge guy very highly recommended. Thank you very much for resolving my issues
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.
After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.
Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.
Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.
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 (their Trustpilot reviews don't lie!). 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.
This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.
I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!

Common LuxPowerTek problems we diagnose
Every fault below has a proven diagnostic path. Book a diagnostic if you're unsure where to start.
LuxPowerTek LXP hybrid connected but UHome battery doesn't charge on cheap rate. Most often a Time of Use schedule configuration error in the LuxPower portal — charge window not enabled, grid charge toggle off, or SoC minimum already met. BST/GMT clock offset is a very common cause.
See diagnostic guide →Lux inverters are configured via the LuxPower portal's TOU schedule. Common issues include charge windows firing at the wrong time due to BST/GMT offset, grid charge being disabled, or the SoC target being set too high so the battery never triggers a charge. We configure the full schedule remotely.
See diagnostic guide →LuxPowerTek UHome (LFP-2400) batteries communicate with the LXP inverter via CAN bus. A BMS comm fault stops the inverter reading battery state, causing it to stop charging or discharging. Causes include a loose CAN cable, incorrect battery address configuration, or a mismatch in battery count settings.
See diagnostic guide →UHome battery fully charged but not powering the house during peak times. Commonly caused by a discharge schedule not set in the LuxPower portal, minimum SoC threshold too high, or the inverter operating in the wrong mode. EPS backup must also be separately configured if needed.
See diagnostic guide →LuxPowerTek LXP hybrid powered but not generating. Check the portal for DC input voltage — if zero or very low, inspect DC isolators and PV string connections. MPPT tracking errors can also suppress production while battery and grid functions continue normally.
See diagnostic guide →LuxPowerTek inverters comply with G98/G99 and disconnect if grid voltage or frequency is outside permitted limits. The inverter reconnects automatically. If trips are frequent — common in dense solar areas — export limiting may need to be configured.
See diagnostic guide →LuxPowerTek LXP inverters support EPS backup mode, but this requires dedicated EPS output wiring during installation and must be enabled in settings. If the house lost power during a grid outage, EPS may not have been commissioned — or the load exceeds the inverter's EPS output rating.
See diagnostic guide →LuxPowerTek uses its own LuxPower monitoring portal. If the portal shows no data, the inverter's WiFi logger has lost its connection — common after a router change or password update. The inverter and battery continue operating normally; only remote monitoring and schedule access is affected.
See diagnostic guide →LuxPowerTek dataloggers require 2.4GHz WiFi. After a router upgrade many connections drop because the new router defaults to 5GHz or uses band steering. We reconfigure the datalogger remotely and restore access to the LuxPower portal.
See diagnostic guide →What we do for Lux Power owners

About LuxPowerTek systems — what you need to know
LuxPowerTek (often referred to as Lux Power or Lux) is a Chinese manufacturer producing hybrid inverters and LiFePO4 battery systems for the UK residential market. Their core UK range includes the LXP-3600, LXP-5000, and LXP-6000 single-phase hybrid inverters, paired with the UHome (LFP-2400) battery module — a 2.4kWh stackable LFP unit with 90% depth of discharge and a 30A charge/discharge rate. Multiple UHome modules can be stacked to build the required total storage capacity. Systems carry an IP65 rating and a 10-year battery warranty.
Monitoring and schedule configuration is managed through the LuxPower monitoring portal (luxpowertek.com). The inverter's WiFi logger must maintain a stable 2.4GHz connection for remote access to work. The most common queries we handle for Lux Power systems: Lux Power battery not charging overnight, LuxPower portal offline, UHome BMS communication fault, Lux grid disconnection, and LuxPowerTek Octopus setup. Lux systems are sometimes sold as Infinity Innovations branded packages in the UK. STS provides independent support — not affiliated with LuxPowerTek.
STS supports all major inverter and battery brands — not just LuxPowerTek. If you have a mixed-brand system (e.g. Lux inverter with Pylontech or Dyness batteries), visit the brand hub.
