Soluna is a new energy solution with internal integrated Energy Management System-EMS, which can control and optimize the flow of energy, thus maximizing the self-used rate of PV generation. The power generated by solar gives priority to load power supply. When the PV energy is surplus, the battery can be charged to store energy, which can be used when there is no light. The excess electricity will be stored in power grid to relieve the pressure of electricity consumption at the peak and increase the consumption rate at the bottom. When there is grid fault, Soluna can switch to backup mode and continues to supply electricy to loads.
