An inverter is one of the most important pieces of equipment in a solar energy system. It''s a device that converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity, which the electrical grid uses. In DC, electricity is maintained at constant voltage in one direction.

Low-voltage solar batteries for home are often used in off-grid systems where customer demand for medium to low energy is high.

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. High voltage battery systems are perfect for properties with commercial energy storage demands and
