Real Experiences, Real Impact
"Recently upgraded my home energy setup - dismantled a single-phase Tesla Powerwall and moved to a 3-phase 15kW Fox ESS Hybrid inverter, CQ6 48kWh, along with a full switchboard upgrade using Hager Type A safety switched. The upgrade was done to better suit a 3-phase home, higher loads, and future expansion. I think it's amazing work by Sparky Amrit Thapa."
Thanks Amrit and GigaWatt Team! Amrit, it was really refreshing to work with someone who listened to what we wanted and just executed! It made the whole process so much more enjoyable. And your attention to detail is on par with my husband's OCD, like a match made Sigenergy heaven. He actually felt like he was part of the install crew considering how much time and questions he asked you .. keep up the great work team."
"Big thank you to Amrit and his team for the excellent work done. The battery installation and switchboard upgrade look fantastic. Special mention to Amrit, he delivered outstanding quality, stayed until 1:45 AM to ensure everything was working perfectly, and showed true dedication. Hats off to him and the team!"
"Sparky Amrit Thapa installed my Sigenergy system late last month and I haven't used the grid since. Had couple of grid outages since installed and we only came to know when a message popped up on the app. So far the experience is amazing. Net up EV charger. Thanks Amrit."

"I would like to commend Amrit and his team for their exceptional work in installing our solar and battery system in a 2-storey house. Their plan was well executed, with the solar panels installed on the first day and the battery system completed the next day, despite the weather forecast of 40^ C. The team's professionalism and expertise are reflected in the quick and neat completion of the project. Their dedication to delivering high-quality workmanship is evident, and I highly recommend them for any solar and battery installation requirements."
