Page 3: About This Manual
ABOUT THIS MANUAL Purpose This manual describes the assembly, installation, operation and troubleshooting of this unit. Please read this manual carefully before installations and operations. Keep this manual for future reference. Scope This manual provides safety and installation guidelines as well as information on tools and wiring. SAFETY INSTRUCTIONS WARNING: This chapter contains important safety and operating instructions. -
Page 4: Operation
Operation 1. Only after wire connection is complete and put cover back to the inverter, it’s ok to do commissioning. Otherwise, it will cause electric shock 2. If sunlight is sufficient but little water is pumped, maybe the wires on motor connection are reversely connected. -
Page 5: Introduction
INTRODUCTION Interest in renewable energy has increased over the past few years due to solar power becoming more cost effective and eco-friendly. This is a solar inverter which allows power to be switched from the DC power obtained from solar panels to the AC power needed to control the pump. With the renewable solar inverter, pumps can adapt to solar power sources rather than traditional electrical supplies or generators. -
