Poor Solar installation and service

Please be very careful when using I solar Solutions. In 2022 they installed a 3kva inverter and what was supposed to have been a 3kva battery. The workmanship of their team was extremely poor and untidy with even the battery hanging visibly not level. On complaining about it they send an electrician than quickly tried to sort out the wire crows nest that the installation team left in my DB board. They never fixed the skew installation of the battery. Our power kept tripping outside at our meter to the main supply to the house since then. We upgraded our system now to a full solar system with a 8kva inverter and 2 x 5kva batteries and panels. The installation team with their electrician pointed out to me that the DB box was breached, not earthed and a smaller cable size was used than the cable coming into the property. This has now resulted in us having to get a qualified electrician to fix I Solar's terrible and very dangerous situation that they created when they did the initial installation. After our initial complaint after I Solar's initial installation and the resulted faults we experienced, not ONCE did the owner or a senior person of the company contact us again or come out to see the problem. I will not recommend them for any solar installation as it has come to light that they are making use of contracted workforce to do their installations. I would be very
