My old solax packed in and was replaced by solar tech support. I am impressed at the very short time scale, sorted in only 3 days. Some were quoting 2-3 weeks. The old unit and all the packing was taken away.

What an amazing service. They got my solar inverter back up and running after a firmware update went wrong. It is a breath of fresh air to deal with such a professional company.

Absolutely brilliant service. Our GivEnergy battery stopped working for no obvious reason. The manufacturers have gone in administration so no aftercare is available. Our installer could not diagnose the problem and gave up. We were at our wits end. A web search came up with Solar Tech Support. In truth, the reviews almost seemed to good to be true. But Ron diagnosed the problem within the hour and fixed it remotely the same day. He explained everything clearly and thoroughly and has offered solutions to other issues we had too. I honestly cannot recommend Ron highly enough. An absolute godsend in the mess that GivEnergy have left behind in their demise. Thank you again for all your help!

My solar panels stopped producing unexpectedly, contacted Ron who assisted me initially remotely and then visited to correctly diagnose that the problem was on the roof. Within a month the solar panels are now up and working, kept me up to date with when scaffolding arriving and the lads who checked the solar panels, a very professional team, organisation and service

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)

Setting up a Solis system — what actually trips people up
Almost every Solis setup job we get is the same one: reconnecting the WiFi datalogger to SolisCloud after a router change, a broadband switch or a WiFi password update. The little plug-in logger on the side or bottom of the inverter stores your network name and password internally, so the moment those change it can no longer connect and the monitoring goes dark. The system usually keeps running, but offline doesn't prove it, so check the inverter's own screen.
The single biggest reason a reconnection fails is the band. Solis dataloggers only talk to 2.4GHz WiFi, never 5GHz, so a combined network that uses one name for both bands, or a mesh system with band steering on, will defeat the setup no matter how many times you try. Past that, it is almost always a mistyped WiFi password or a logger that needs popping back into configuration mode with its reset button. The logger's three LEDs — PWR, NET and COM — tell you which stage has stalled before you touch anything.
As independent engineers we're happy for you to reconnect the logger yourself with our step-by-step guide, free. If it still won't connect, we set it up on site, from £195: we connect it to your WiFi, set up your router, including a separate 2.4 GHz network if it needs one, and check it's reporting. If the signal doesn't reach, a WiFi extender is an extra £75, and we carry them with us. If the logger has genuinely failed, we say so and point you at a replacement.

Solis setup questions answered
Nine times out of ten it is the band. Solis dataloggers only support 2.4GHz WiFi — they cannot use 5GHz at all. If your router broadcasts both bands under one name the logger may try to join 5GHz and fail, and mesh systems like Eero, Google Nest or BT Whole Home often need band steering disabled. Use the 2.4GHz network name and password during setup. After that the usual culprits are a single mistyped password character or a logger that has dropped out of configuration mode — hold its reset button for about ten seconds to put it back into broadcast mode, then run the setup again in the SolisCloud app. The NET LED tells you where you are: flashing green means powered but not connected, solid green means it is on your WiFi and uploading.
Someone needs to be physically near the inverter, because during setup your phone connects directly to the logger's own WiFi network (named Solis_ followed by its serial number) to hand over your home credentials — that only works within range of the logger. We don't set up or diagnose WiFi remotely or over the phone: it's quicker and more reliable done on site. Doing it yourself with our guide is free: check the PWR, NET and COM LEDs, confirm your router is broadcasting 2.4GHz, work through the SolisCloud app, and check data is flowing again afterwards. If it still won't connect, we set it up on site, from £195: we connect it to your WiFi, set up your router, including a separate 2.4 GHz network if it needs one, and check it's reporting.
No — the period the logger was offline is gone and cannot be recovered, which is normal; the logger only resumes uploading from the moment it reconnects, so live generation and a current timestamp in SolisCloud confirm success. The good news is that while the logger is offline, the system usually keeps running, so check the inverter's own screen: you have usually lost data, not energy. On cost: our step-by-step guide is free, and if the logger won't reconnect, we can set it up on site, from £195, including a new logger's first-time setup. If the datalogger turns out to be dead, or another fault needs hands-on attention at the inverter, on-site repair is from £295 and always quoted before we book anything.
