High-voltage systems enhance ''DC (PV) → DC (BAT)'' energy conversion efficiency. In low-voltage 48V home storage systems, the inverter must step down the DC voltage from the PV side (the BUS voltage of a single-phase inverter typically ranges from 360V to 500V) to charge the 48V battery, leading to significant energy losses.
Higher voltage = greater efficiency: Larger systems benefit from higher voltage by reducing cable size and power loss. Match your inverter: Your battery bank should match the voltage your inverter is designed to support.
Consequently, as Munzke et al. stated, the most significant energy losses of battery PV systems were influenced by the energy conversion process of the inverter. According to the results obtained, ɳ i in HVI was higher than LVI in all tests.
For a given energy capacity, high voltage systems require less expensive cable materials compared to low voltage systems, resulting in cost savings for installation and maintenance. As the energy storage industry evolves, high voltage batteries are proving to be the superior choice for modern home energy systems.
