1. INTRODUCTION
This training manual has been specifically designed around the Sunsynk Super Hybrid Parity Inverter. It
has been written to give you a clear understanding of how to install the inverter, however, users are advised
to the inverter handbooks for detailed programming.

1.1. WHAT IS A HYBRID INVERTER
The word ‘hybrid’ means a mixture of two different things or technologies. In the field of electrical
engineering, a hybrid inverter means an inverter that can connect several power sources together, such as
Alternate Current (AC) from the mains grid, battery (Direct Current (DC)), and solar (DC). In other words, it
may have many different variants. However, the term 'solar hybrid inverter' usually refers to an inverter that
connects to AC power, solar PV panels, and batteries.
The batteries can be charged both from the AC and solar power, and the inverter can supply the AC
output. With this technology, the hybrid inverter can store energy at night by charging the batteries from the
mains-grid when the energy price is low, and then, during the daytime, the load can take power from the
batteries, thereby saving electrical bills.
