TL;DR
A battery inverter is the power electronics unit that converts a home battery's DC into household 240-volt AC and reverses the process to charge, managing the battery separately from the solar array. It defines an AC-coupled storage system, where solar panels keep their own inverter, the architecture of products like the Tesla Powerwall and most storage retrofits to existing solar.
What it means
A battery inverter is the power electronics unit that converts a home battery's DC into household 240-volt AC and reverses the process to charge, managing the battery separately from the solar array. It defines an AC-coupled storage system, where solar panels keep their own inverter, the architecture of products like the Tesla Powerwall and most storage retrofits to existing solar. Ratings that matter are continuous output, commonly 5 to 9.6 kW, surge capacity for motor starts, and UL 1741 grid-interconnection compliance. During outages it must also form a stable local grid, a capability called islanding that simple grid-tie inverters lack.
