We reached out to Solar Technical Support after our solar energy system stopped working. As GivEnergy 'solar orphans,' we have been extremely pleased with the service from STS - our system was back up and working within a day of us contacting them. We found other solar engineers reluctant or unable to help us, so it has been great to find this organisation. We would definitely use them again and would recommend them to anyone, especially GivEnergy orphans!
Ron responded very promptly regarding my GivEnergy battery issue, his knowledgeable diagnosis was spot on and resolved the issue on first attempt. Would recommend to any and all.
Saw Ron was advertising a refurbished 9.5 kWh on Facebook, within a couple of days Ron delivered and installed it into my current system, my existing 9.5 batter was also. Gen 2 running on firmware 3022. Literally took him 30 mins, from start to finished, within a couple of days the two batteries had balanced themselves, it’s now been a week with Predbat in control. Working perfectly , could not recommend Ron more highly Top Man!
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.
We moved from BT to Vodafone recently. Unfortunately our GivEnergy AIO would no longer appear on the App. Additionally our GivEnergy EV charger stopped working. Vodafone insisted that their dual 2.4ghz and 5ghz compatibility mode would work with the 2.4ghz system. Unfortunately it doesn't. After nearly two weeks of trying to sort this, which also involved searching on various chat forums, I sent an email for help to STS. Within a very short time the same day I got a call from Ash, who is only 45 minutes away from us. He came and quickly got the AIO appearing on the app, so we could once again see the state of the battery. The EV charger presented more of a challenge as the QR code fixed on the side of the charger had worn away. Ash was able to find the necessary information to restore the EV charger to working order. I have a copy of the QR code and other information should we have an issue another time. I had bought a TP-Link TL-WA850RE that just works on 2.4ghz and this is linked permanently to the GivEnergy kit. STS are definitely the people to contact if you find yourself in a similar situation. We are very happy with the service STS provided.
Following an email enquiry i was able use Whatapp Chat to work with their online support agent who successfully solved my battery problem. Having been told that it had gone into sleep mode and would require a site visit Solar Tech successfully sorted the problem remotely. No hassle and no success no fee.

Dyness batteries work with many inverter brands — faults are often in the communication layer or the inverter's schedule, not the battery itself.
Dyness batteries rely on the paired inverter's Time of Use schedule. If the battery isn't charging overnight, the fault is almost always in the inverter configuration — not the Dyness battery itself. We diagnose both the inverter schedule and the battery BMS communication layer.
See diagnostic guide →Dyness battery fully charged but the inverter isn't drawing from it. Check the discharge schedule and minimum SoC threshold on the inverter. If the Dyness has a BMS protection trip active (e.g. over-temperature, cell imbalance), the battery will refuse to discharge until cleared.
See diagnostic guide →Dyness B4850 is a 48V low-voltage module (2.4kWh each, stackable to 10 units). Common issues: module address conflict when stacking multiple units (DIP switch misconfiguration), one module triggering a protection fault causing the whole bank to shut down, or cell imbalance in older stacks.
See diagnostic guide →The Dyness Tower Pro is a high-voltage modular system (3.84kWh per module). Common issues: HV insulation fault on first start (often a loose connection in the HV stack), BMS master/slave assignment errors when adding modules, or fire suppression system triggering unexpectedly on early units. Requires HV-qualified engineer for physical checks.
See diagnostic guide →We review inverter logs, BMS communication data, and battery error history to identify whether the fault is in the Dyness battery, the inverter, or the communication layer.
We configure the correct Dyness battery protocol, DIP switch addressing, and battery bank capacity settings on the paired inverter. Covers all common inverter brands that support Dyness batteries.

Dyness is a Chinese battery storage specialist that produces modular LiFePO4 battery systems designed to work with most hybrid inverters on the market. Their UK range includes two main products: the B4850, a low-voltage (48V) battery providing 2.4kWh per module, stackable up to 10 modules (24kWh), with an 80% depth of discharge and a 10-year warranty; and the Tower Pro, a high-voltage modular system delivering 3.84kWh per module, stackable 2–6 modules per tower (7.68–23.04kWh), with IP55 weatherproofing, a 1C charge/discharge rate, and a 15-year warranty. Some Tower Pro configurations include an integrated fire suppression module.
Because Dyness batteries are inverter-agnostic, they pair with many hybrid inverters — common UK combinations include Sofar, Solis, GivEnergy, and LuxPowerTek inverters. Fox ESS lists only its own high-voltage batteries for its hybrid inverters, so a Dyness battery is not a supported pairing there and may affect the warranty: see our Fox ESS support hub and our guide to adding a battery. The battery communicates via CAN bus or RS485 depending on the inverter, and the correct protocol must be selected on the inverter for the pairing to work. The most common queries we handle: Dyness battery not charging, Dyness BMS communication fault, Dyness B4850 module fault, Dyness Tower Pro error, and Dyness inverter compatibility. STS provides independent support — not affiliated with Dyness.
STS supports all major inverter and battery brands. If your Dyness battery is paired with a specific inverter brand, visit that brand's page for inverter-specific guidance.
