Here are some features of the SPI-8-12K-H3P

• Supports lead-acid battery and li-ion battery connections. – With a dual activation function when the li-ion battery is dormant; either mains or photovoltaic power supply access can trigger the activation of the li-ion battery. 
• Support three-phase pure sine wave output (350~415V). – Supports phase voltage adjustment in the range of 200, 208, 220, 230, 240Vac.
• Supports two PV inputs, with the function of simultaneously tracking the maximum power charging or carrying capacity of two MPPT.
• Dual MPPT, efficiency up to 99.9%, single maximum current of 22A, perfectly adapted to high-power modules.
• 4 charging modes are available: solar only, mains priority, solar priority, and mixed mains and PV charging.
• With time-slot charging and discharging setting function, it helps users to take advantage of peak and valley tariffs and save electricity costs.
• Energy-saving mode function to reduce no-load energy losses.
• With two output modes of utility bypass and inverter output, with uninterrupted power supply function. 
• LCD large screen dynamic flow diagram design, easy to understand the system data and operation status. 
• 360° protection with complete short-circuit protection, over-current protection, over- voltage protection, under-voltage protection, over-load protection, etc. 
• Support CAN, USB, and RS485 communication.
