Grid-connection approval and commissioning: from the access request to the bidirectional meter

The system is installed and measured. Now the utility has to accept it. This is where many good jobs get stuck: a different capacity figure in each document, an expired connection budget, a service entrance with a requirement, an inspection failed over a sign. This course follows the Aguaí house from SO3 (4.1 kWp, two microinverters, two-phase 63 A service entrance) all the way to the first bill with credits. You place the system under Law 14,300 and REN 1,000 (the Brazilian net-metering law and the regulator's rules for grid service), build the dossier document by document, file it in the portal and count the deadlines in calendar days and business days. You resolve the upgrades the utility asks for, with the available-capacity calculation. You commission under NBR 16274 (the Brazilian standard for PV commissioning tests, derived from IEC 62446) with tests per microinverter input, write the report and photograph what the inspector wants to see. Finally, you follow the inspection, read the bill with compensation and hand the system over to the customer with monitoring, manual and warranty term. It does not go into minigeneration or shared generation, and it does not qualify you to sign an ART or TRT (the Brazilian technical responsibility documents).
