Yes, the inverter of a balcony power plant, also known as a “plug-and-play” solar system, can be legally and safely connected to your home network. These systems typically include one or two small solar panels and a micro inverter that can directly plug into a standard household electrical outlet.
Most municipalities require you to pull permits before solar inverter installation begins. After installation, local building or electrical inspectors will verify that your system is safe and code-compliant before it can be connected to the grid. Your local utility will have its own guidelines for connecting a solar energy system to the grid.
During your solar inverter installation, your installer should inspect and reject unsuitable locations. If an ideal indoor space isn't available, an outdoor installation with a weatherproof enclosure is usually the next best solution. How far can a solar inverter be from the main panel?
Indoor installations should avoid small closets or enclosed cabinets. Proper placement is a low-effort, high-impact part of any solar inverter installation. Not all electricians are trained to perform solar inverter installations, and not all solar installers follow best practices.
