All-in-one solar battery, which integrates inverter and solar energy storage and means storage of charging energy and AC sine wave output. Thanks to DSP control and advanced control algorithm, it has high response speed, high reliability, and high industrial standards. Four charging modes are optional: Solar Only, Grid Priority, Solar Priority, and Hybrid Grid and Solar Charging; and two output modes are available, namely Inverter and Grid, to meet different application requirements. Stable AC sine wave output via SPWM modulation Supports a wide range of battery technologies: sodium ion. Dual SIB battery activation method: PV and grid power supply Uninterrupted power supply: simultaneous connection to grid/generator and PV. Intelligent programming: it is possible to set the output priority from different energy sources. High energy efficiency: MPPT capture efficiency up to 98%. Instant operation display: the LCD panel displays data and settings, while it is also possible to view them via app and web page. Energy saving: the energy saving mode automatically reduces energy consumption at zero load. Efficient heat dissipation: via intelligent variable speed fans Multiple safety protection functions: short circuit protection, overload protection, reverse polarity protection, and so on. Undervoltage and overvoltage protection and reverse polarity protection. Supports up to 4 devices of the same model connected in parallel (forming a single-phase, two-phase, or three-phase electrical system) For single-phase configuration, the system is expandable up to 18kW and 72kWh and for three-phase configuration, you need to connect 3 units forming a 15kW and 54kWh battery system ready for any situation and it is possible to reach 4*3 units at 60kW and 216kWh of storage for commercial and public systems.
