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. -

INSTALLATION Unpacking and Inspection Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should have received the following items inside of package: The unit x 1 User manual x 1 RJ45 cable x 1 ... -
Page 8: Pv Connection
Install the unit by screwing four screws. It’s Drill four holes in the marked locations with four recommended to use M5 screws. screws. PV Connection CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter C8A/2P/1000VDC/25KA for 2.2KW, and PV modules. -
Page 9: Ac Output (Motor) Connection
PV Module Selection: When selecting proper PV modules, please be sure to consider below parameters: 1. Open circuit Voltage (Voc) of PV modules not exceeds max. DC voltage (800VDC). 2. Accumulated voltage of connected PV panels should be close to 560V for inverter with 380V output voltage. To calculate PV module numbers in series (N) and in parallel (M), please follow below formula: Imp>Po/(Kvo x 0.9 x M) ... -
