My Givenergy battery stopped working nearly a month ago. After unsuccessfully reaching out to my installer, who looks like he's also busted, I found Solar Tech Support on a Google search. They fixed my issue in a couple of hours. Any frustrated Givenergy customers, I highly recommend these guys.

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.

Ron is incredibly knowledgeable about solar installs in general but knows givenergy products inside out and the key personnel that worked there from the start to the end. My problem was spurious in its nature but Ron spotted it straight away when he understood the installation details. In essence the installers didn’t fit the correct trip switch. He also gave me hope that in the future hardware repairs could be possible but it’s still early days. This guy really is in the know and keen to sucas a business If you need help don’t hesitate

Setting up Growatt monitoring — what to get right
Growatt monitoring runs through two interfaces that share one login: the ShinePhone app and the ShineServer web portal at server.growatt.com. The setup itself is straightforward — register an account, create a Plant for your property, then add your inverter using its serial number — but two things trip people up. First, always register with an email address you own and control, not your installer's; an account tied to an email you can't access is the single most common reason homeowners lose monitoring later. Second, add the device using the inverter serial from the label (a 10-character code), not the WiFi datalogger's own serial — get those two mixed up and the device can show as registered but report no data.
The job that brings most people here, though, is the dreaded "device already registered" message. Growatt systems installed before about 2022 were almost always registered under the installer's ShineServer account, so when you buy a house with solar or your installer goes bust, you inherit a system you can't see. You can't override it from your end. If the installer is still trading they can reassign the Plant to you inside ShineServer, often same day with no paperwork; if they're gone, it's a formal orphaned-account transfer through Growatt UK at service@growatt.com — serial number, address and proof of ownership, typically 3 to 7 working days. Our ShinePhone setup and account transfer guide walks through both routes step by step.
As independent engineers we'll get you set up properly or prepare a transfer request that lands right first time. If something's actually broken — the datalogger won't connect, or the app shows no data after setup — the remote diagnostic is free and you only pay from £75 if we fix it remotely. Hands-on setup help is quoted up front, and on-site work, where it's ever needed, starts at £245.

Growatt ShinePhone setup — common questions
It means the inverter serial is already linked to another ShineServer account, usually your installer's or a previous homeowner's, and you can't force a fresh registration over the top of it. There are two routes. If the original installer is still trading, ask them to reassign the Plant to you inside ShineServer — that's the quickest fix, often same day with no documentation. If they've gone bust or are unreachable, it's an orphaned-account transfer: create your own ShinePhone account first, then email Growatt UK at service@growatt.com with your inverter serial number, the property address, proof of ownership (a completion statement, Land Registry document or solicitor letter) and your account email so they know where to move the device. Growatt typically processes these in 3 to 7 working days. We'll prepare the whole request so it's right first time, and we can't speed Growatt's side up but we can make sure it isn't bounced back for missing information.
Use the inverter serial number, not the datalogger's. It's printed on a white or silver label on the side or bottom of the inverter — look for the field marked S/N or Serial No. — and on most Growatt models it's a 10-character code, letters followed by numbers. It should also appear on the commissioning certificate or system spec sheet in any handover pack left by the installer. The WiFi datalogger has its own separate serial on a different sticker; if you accidentally register that one, the device can look registered but show no live data. If you enter the wrong one, remove the device from your Plant and re-add it using the inverter serial taken straight from the label.
After adding the device, allow 5 to 10 minutes for the first data to appear, as the datalogger reports at intervals rather than continuously. If it's still blank, the device is registered correctly but the WiFi datalogger isn't transmitting — which is a connectivity issue, not an account problem. The usual causes are the datalogger not being on your home WiFi (it needs your 2.4GHz network, not the inverter's own hotspot), or a router or WiFi password change since installation that's left it disconnected and needing reconfiguration. Your inverter keeps generating and charging throughout; only the monitoring is down. This is exactly the kind of fault where the remote diagnostic is free and you only pay from £75 if we fix it remotely — no fix, no fee. The rare cases that need an engineer on site, such as a failed datalogger, are scoped and quoted before anyone travels, with on-site visits from £245.
