Power Sonic Limited

Mark has been very helpful, he changed the set up a few times for us and has succeeded in getting the most out of our roof and fitting in the Sigenergy Stack and Gateway. The install was professionally carried out and Mattie, Nathan and Mike installed the panels in nearly freezing conditions with it raining all day. Thank you to Laura and Mark for answering all the questions I had leading up to the install! And thank you Mark for resolving the issue quickly I created in the Sigenergy App when 4 days after the install the local DNO tested the backup with a power cut.

Having carried out my diligent research over several weeks, I narrowed down my options for solar and storage batteries installation to three trustworthy companies. Of these, Power Sonic Ltd also covered my area of the country, indeed I believe they cover nationwide installations. To reinforce my choice I watched several of Mark's videos on YouTube and was both impressed and reassured by Mark's attention to detail in all his installations. In January as promised, Mark contacted me with a proposed installation date having received DNO approval to export over the standard 3.68kW to the grid. Upon my acceptance of the proposed installation date, Laura, office manager and wife of Mark, expedited the vetting of a local scaffolding company and booked there services for a few days before the solar installation. On the 26th, Mark and Nathan arrived and began the installation of the gateway, and the fixings for the solar panels on the tiled house roof. Day two was a blustery day. Mark and Nathan were joined by Matthew and Michael and between them they installed most of the cables, neatly routing the main solar cable through the loft. Day three was a glorious day weatherwise, blue sky and no wind. The team worked professionally and considerately to complete the fixings and rails on the roof before the installation of 19 solar panels and bird mesh. The four Sigenergy 10 batteries plus inverter were assembled in minutes. Everything went smoothly over the three days thanks to Mark's meticulous planning and the support of his dedicated team. I normally struggle having contractors working in and around my home but I would thoroughly recommend Mark and his team for completing this installation to my complete satisfaction. Mark scheduled the installation to take three days and despite the intervention of storm Chandra on the second day, the full installation and commissioning of the system was completed by 16:00 on the third day.

5 star installer of our Sigenegy battery storage system in garage and solar panel arrays on Northeast and Southwest roof. Well detailed quotation and obliging in additional work (new consumer unit). Excellent communication. Very professional work carried out and respectful of our property. Full instructions on operating the system given when the installation was commissioned. Very pleased with a job well done and would recommend Power Sonic Ltd to anyone looking to have Solar and Battery Storage fitted in the future.

Matt and Nathan came to install a new 18kWh Sigenergy plant for our battery backup, and I am very pleased with the job they did, very professional. Kept me updated on progress, and did a tidy job and cleaned up well after themselves. Great support, before from Mark & Laura, and whilst I haven't needed it so far, Mark offered to help with any questions/support after installation. Will get in touch again with Power Sonic if I need solar/battery work in future.

I would like to thank Power Sonic (Mark, laura, Mattie & Nathan) for doing a great job. From the very first email sent to job completion the whole project went very smoothly, I was kept informed every step of the way and all my questions answered. My Sigenergy system was very professionally installed and has been working great. I would highly recommend Power Sonic a friendly family run business that gets the job done.
