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.

Hugh Speirs · Apr 2026 Trustpilot

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.

Andy Thomas · Apr 2026 Trustpilot

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!

About Dyness batteries — what you need to know

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, Fox ESS, GivEnergy, and LuxPowerTek inverters. 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.

FAQ

Dyness battery questions answered

Dyness batteries don't hold their own schedule — charging is controlled by the paired inverter. First, check the inverter's monitoring platform for the Time of Use schedule. The charge window must be enabled, grid charge must be on, and the SoC minimum must be below your current state. If the schedule looks correct but charging still fails, check for a BMS communication fault in the inverter's event log.
The B4850 is a low-voltage (48V) system — 2.4kWh per module, stackable to 10 units (24kWh), suited to standard hybrid inverters. The Tower Pro is a high-voltage modular system — 3.84kWh per module, 2–6 modules per tower (7.68–23.04kWh), with IP55 protection, a 15-year warranty, and a 1C discharge rate. The Tower Pro requires a high-voltage capable inverter and should be serviced by an HV-qualified engineer.
Dyness batteries are designed to be inverter-agnostic via CAN bus or RS485. Common UK pairings include Sofar, Solis, Fox ESS, GivEnergy, and LuxPowerTek. The correct communication protocol must be selected on the inverter during commissioning — using the wrong protocol is one of the most common causes of BMS communication faults. We verify the full communication chain remotely.
A BMS comm fault means the inverter has lost contact with the Dyness battery management system. The battery will refuse to charge or discharge as a safety measure. Causes include: wrong communication protocol selected on the inverter, incorrect DIP switch address on one or more battery modules, a damaged CAN or RS485 cable, or a firmware version mismatch. This is typically diagnosable remotely from the inverter's event log.
