Remote-first using portal data and charge schedule logs, but WiFi isn't remote work: if the datalogger needs reconnecting to your WiFi, we can set it up on site, from £195. Independent from LuxPowerTek and your installer.

Safety: If your UHome battery is showing error lights or unusual behaviour, isolate at the DC switch before investigating.

Particularly useful in helping to fix my GivEnergy All in One system with a disabling fault.

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.

⭐⭐⭐⭐⭐ Absolutely Outstanding Service! My GivEnergy system had completely gone down, and unfortunately I was getting absolutely no support from either the original fitter or the supplier. I was left completely stuck with a system that wasn’t working. I contacted Solar Tech Support and they were absolutely brilliant from start to finish. They quickly got to the bottom of the problem, knew exactly what they were doing, and managed to get my entire system back up and running. Hands down, these guys are absolute experts in their field. The level of knowledge, professionalism and customer service was exceptional, especially when I’d already been left without any support elsewhere. If you have a GivEnergy system and you’re struggling with an issue, don’t hesitate to contact Solar Tech Support. I honestly can’t recommend them highly enough. 5 stars all day long! 🌟🌟🌟🌟🌟

Contacted Solar Tech about my Givenergy battery storage system that wasn't working. Battery status was "idle". Given the company Givenergy had gone bust, I need independent quality technical help. Very patient and clearly very knowledgeable about battery systems Ron diagnosed possible issues and suggested several possible remedies. Worked our way through them and fortunately it began to work. The fault was very specific and only an experienced engineer would have thought to check. Suffice to say I'll be back if I need independent support again. Lastly you only pay if there is a solution. Outstanding.

The Solar Tech Support company was the only one to respond to a request for someone to supply and fit a new inverter for our solar panels after our old one finally expired after 26 years. Ron kept us well informed throughout, came and ascertained that the issue was down to the inverter having failed then sourced and fitted a new one. He got the system up and running again, set up the wi-fi performance feedback and took away the old inverter for disposal. By acting promptly and fitting the job around existing commitments we were able to get our solar power unit back in operation with minimal delay in the short while before we were due to go away for a week. The work was carried out very professionally and we were asked to confirm that all was in order the following day. I was impressed that, having recently taken on additional work for GivEnergy customers we were able to keep our solar panel down-time to a minimum. I would highly recommend for prompt attention and first-rate service.

Made contact for assistance with my GiveEnergy battery that wasn't discharging. Ronald looked at my issue the same day, identified the root cause with a clear explanation of what was going on along with some options on how to remediate the issue. So far my battery is now working and keeping my fingers crossed that it stays this way. Ronald is a very experienced and knowledgeable engineer and I would recommend.

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.

FAQ

LuxPowerTek questions answered

The most common causes are: the charge window not being enabled in the LuxPower portal TOU schedule, grid charge being disabled, the SoC minimum already being met so the battery never triggers a charge, or a BST/GMT clock offset causing the window to fire at the wrong time. We reconfigure the full schedule remotely.
The UHome (LFP-2400) is LuxPowerTek's low-voltage (48V) LiFePO4 battery module, providing 2.4kWh of usable capacity per unit. Multiple modules can be stacked to reach the required total capacity. Each module communicates with the LXP inverter via CAN bus and charges/discharges at up to 30A. The 90% depth of discharge means nearly all the stated capacity is accessible in daily use.
The LuxPower portal requires a stable 2.4GHz WiFi connection from the inverter's datalogger. After a router change, password update, or BT/Virgin Hub firmware push, the logger loses its connection. It's often only remote monitoring and portal access that's affected: the system usually keeps running, so check the inverter's own screen. If the datalogger won't rejoin your WiFi, we can set it up on site, from £195.
Yes. We configure the TOU charge and discharge windows in the LuxPower portal to correctly use Octopus Agile, Go, Intelligent, Flux, or any other time-of-use tariff. This often resolves overnight charging complaints that are configuration errors rather than hardware faults. Most configurations are completed in a single remote session.
