The DC bus voltage normally varies between 300 volts and 500 V, so when you choose this option your inverter has less work to do. When you choose a low-voltage home battery backup, the inverter needs to work harder and reduce an input voltage of 300 -500V below 100 V. This results in less energy efficiency for your home or business''s power requirements.
