      abstract     = {Due to the intermittent nature of solar irradiance and the
                      temporal mismatch between solar power generation and
                      consumption profiles, the combination of photovoltaic (PV)
                      devices with energy storage is essential. The maximum power
                      point tracking (MPPT) devices are commonly used for the
                      connection of PV to electrochemical storage and load,
                      ensuring power matching and providing flexibility in system
                      design. Herein, the usability of direct PV-battery coupling
                      as an alternative to MPPT under realistically varied battery
                      state of charge (SoC), irradiance, temperature of the PV
                      module, and applied load is investigated. A stable power
                      coupling factor above $90\%$ is demonstrated between a
                      silicon heterojunction solar module and Li-ion battery in
                      the whole range of measured SoC $(12.5–75\%)$ and a wide
                      range of load power. The dependence of power coupling on
                      temperature and irradiance is calculated and compared to the
                      power generation profile of a PV plant installed in southern
                      Germany. In the region of highest power generation, the
                      direct connection provides coupling efficiencies above
                      $95\%,$ reaching $100\%,$ for the usable range of battery
                      SoC. These results show that direct PV-to-battery coupling
                      is feasible for a variety of practical applications and
                      scales.},
