Introduction - Epever SHI2000-22-G User Manual

1 Introduction

Thank you for purchasing SHI series inverters. The product is a
pure sine wave inverter which can convert 24/48V DC to 220/230V
AC 50/60Hz based on full digital and intelligent design. It has the
mains supply bypass switchover function. It features high reliability,
high efficiency, concise outline, small volume, full protection
functions, easy installation and operation, etc. The inverter can be
applied in many fields, such as household appliances, electric tools
and industrial devices etc, especially for solar photovoltaic power
system.
Features:
◆ It provides the mains supply bypass changeover function and
can be switched to the inverter priority mode or bypass priority
mode.
◆ Input and output complete isolation-type inverter technology.
◆ Adoption of advanced SPWM technology, pure sine wave
output.
◆ Dynamic current loop control technology to ensure inverter
reliable operation.
◆ Wide DC input voltage range.
◆ Low output harmonic distortion (THD≤3%).
◆ LED indicators for input voltage range, load power range,
normal output & failure state.
◆ The output voltage and frequency (need to be consistent with
the bypass voltage and frequency) can be switched
automatically.
◆ Extensive protections: short-circuit, overload, AC input
under/over input voltage, bypass under/over input voltage,
reverse polarity (the fuse is damaged), over-temperature, and
