Amazing! I was having trouble with a flat GivEnergy battery and solar panels not working. I contacted through WhatsApp and we managed to get it all sorted within a couple of days! Super fast service. I can’t thank you enough for your help when my installer didn’t want to know and GivEnergy has gone in to administration! I know where to go if anything happens again!

Fantastic support. We have a Givenergy system where one of our batteries was not working. Ronald successfully helped us get it back up. His perseverance was amazing….and it shows what REAL customer service means. Can’t thank you enough Ron!

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. 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.

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.

Great service from STS after a power cut and brownout left my GivEnergy inverters effectively useless. After filling the enquiry form out I was promptly given clear instructions by email explaining how to run their diagnostic software and they were working remotely in minutes. Soon after my inverters were back running again. Very helpful and knowledgeable people - thank you.

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.

Setting up a Victron system the right way

Victron is not a single-box brand. There is no setup wizard that does it all in ten minutes. The inverter-charger, the MPPT controller, the battery monitor and the Cerbo GX are separate products that each need configuring and then integrating, which is exactly why so many systems end up half-commissioned. The two jobs that catch people out are commissioning a MultiPlus-II for a UK grid-connected ESS, and getting VictronConnect and VRM monitoring working from scratch.

On the MultiPlus-II the order matters. You set the country code and AC input limit in VEConfigure, add the ESS assistant (without it the unit just passes grid through and never charges the battery from solar), select the right UK grid code (G98 up to 3.68kW single-phase or 11.04kW three-phase, G99 above that), then enable DVCC on the Cerbo GX so the battery BMS controls the charge limits. Skip a step and the system underperforms or refuses to charge. The monitoring side has its own snags: VictronConnect Bluetooth only allows one connection at a time and cannot install assistants, the Cerbo GX WiFi antenna is weak so Ethernet is far more reliable, and VRM only works with a GX device claimed to your account by its portal ID.

Because Victron exposes nearly everything through VEConfigure and the VRM remote console, most of this can be done with us guiding you, no installer visit required. Remote commissioning or VRM setup is a fixed £145 once the Cerbo GX is online. WiFi isn't remote work: if the Cerbo GX isn't on your WiFi yet, or has dropped off it, we can set it up on site, from £195. If a system that was working has stopped, or a wrong setting is causing a fault, the remote diagnostic is free and you pay £125 only if we fix it. Where a job genuinely needs hands on site, such as an MK3-USB firmware recovery, it is quoted before anything is booked.

FAQ

Victron setup questions answered

Yes, for any UK grid-connected battery system. The ESS assistant is a software module you add in VEConfigure under the Assistants tab, and without it the MultiPlus-II only runs in passthrough or off-grid mode: it will not charge the battery from solar or discharge to offset your household consumption. During installation it asks for a grid setpoint (50W is standard for self-consumption) and whether grid feed-in is allowed (enable it if you have an export tariff and your DNO permits export). It cannot be edited later, so if you need to change a setting you re-run the assistant from scratch. We can talk you through the whole sequence remotely, or do it for you via the VRM remote console, as a remote setup session at a fixed £145.
Often, yes. For VRM you need a GX device (Cerbo GX, Venus GX or Cerbo-S GX) connected to the internet, ideally by Ethernet rather than the weak internal WiFi, then you claim the installation on vrm.victronenergy.com using the portal ID printed on the device. Once that is done and remote console is enabled, we can configure the system through VRM without an MK3-USB adapter at all. The adapter is only essential for installing the ESS assistant on a MultiPlus-II when there is no GX device online yet, or for recovering a unit after a failed firmware update. We diagnose what you actually need first, free of charge. WiFi isn't remote work, though: if the GX device isn't on your WiFi yet, we can set it up on site, from £195.
The remote diagnostic is free: tell us your hardware (MultiPlus model, MPPT, GX device and battery brand) and where you have got stuck, and we tell you exactly what is left to configure at no charge. Setup work we can do remotely (VEConfigure parameters, the ESS assistant, grid code selection, DVCC, VictronConnect pairing, firmware updates or VRM registration) is a remote setup session at a fixed £145. If a system that was working has stopped, or a wrong setting is causing a fault, you pay £125 only if we fix it: no fix, no fee. Physical work, such as an MK3-USB firmware recovery or Ethernet cabling to the Cerbo GX, is done on site from £295 and quoted before anything is booked. WiFi isn't remote work: if the Cerbo GX isn't on your WiFi yet, or has dropped off it, we can set it up on site, from £195.
