Why can the AC output energy conversion efficiency of OYSD energy storage system reach 99.5%?

Because our energy storage system adopts the world's leading dynamic series technology inside, it directly outputs AC by adjusting the number of batteries connected in series so that the total voltage of batteries connected in series changes with a sine wave. Very low (<1mΩ), omitting the low-efficiency PCS, so a very high-efficiency output can be achieved.

After the OYSD energy storage system has been installed and used for a period of time, can I still increase its output power and storage capacity by adding modules?

When the grid voltage is unstable, can the OYSD energy storage system achieve a stable output voltage?
