Plan Distance Between Components
Follow the table below for maximum distances for wired communication between system components. Wire gauge must meet local codes.
What is the distance requirements between Solar Panels/Inverter, battery storage unit and consumer unit? My electrician insisted that the storage battery we have - Growatt B3-Alpha and an additional battery module should be no more than 2-4 meters away from consumer unit.
When considering the solar panel inverter distance, one of the first things to remember is how far your inverter and battery are from the main electrical panel. For example, placing your inverter and battery in a guest house 100 feet away from the main panel can affect your system's performance. Voltage Drop and Efficiency
If the distance is too long, it can cause a significant decrease in the voltage, meaning less electricity will reach the inverter from the solar panels. To minimize voltage drop, it is recommended to keep the distance within 30 feet (9 meters) between the solar panels and the inverter.
It does not have to be exact, but the batteries and inverter should be pretty much in the same room. You can mount the inverter inside or outside the building near the meter box if your home is grid-tied. Overall, the solar panels and the inverter should be close, and the wiring to the house should not be more than 30 feet.
