2. Production Instructions
2.1、Instructions
SEI-SP series is a new type of solar energy storage inverter control inverter integrating solar energy storage
& utility charging and energy storage, AC sine wave output. It adopts DSP control and features high response
speed, reliability, and industrial standard through an advanced control algorithm.
Energy consumption
Battery discharging
• Supports lead acid battery and li-ion battery connections.
• With a dual activation function when the li-ion battery is dormant; either mains/photovoltaic power supply
access can trigger the activation of the li-ion battery.
• Support single-phase pure sine wave output.
• Supports four different voltage levels of 200\208\220\230\240Vac per phase.
•
Supports two solar inputs and simultaneous tracking of two solar maximum power charging/carrying
capacity functions.
•
Dual MPPT with 99.9% efficiency and maximum 22A current in a single circuit, perfectly adapted to high
power modules.
• 2 charging modes are available: solar only, mixed mains/PV charging.
• With the time-slot charging and discharging setting function, you can set the time period for cutting in/out
of mains charging and switch the time period between battery discharging and mains bypass power
supply mode.
• 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 under voltage
protection, overload protection, backfill protection, etc.
•
Support CAN, USB, and RS485 communication.
