Page 3: About This Manual
ABOUT THIS MANUAL Purpose This manual introduces the assembly, installation, operation and troubleshooting of inverter. Please read this manual carefully before installation and operation. Target Group This manual is designed for professionals and end users. Operations that do not require any specific skills can also be handled by the end users themselves.
Page 4: Introduction
still errors after troubleshooting, please send this off line solar inverter back to the local dealer or service center for maintenance. INTRODUCTION This is a multifunctional off grid solar inverter, which integrates MPPT solar charging controller, high-frequency pure sine wave inverter and UPS function module, and is very suitable for off-grid backup power supply and spontaneous self-use system.

INSTALLATION Unpacking And Inspection Unpack the inverter and make sure there are no damaged objects in the package. You should have received the following items inside of package: ● Machine x 1 ● User manual x 1 Preparation Before Installation Before connecting all wirings, please take off bottom cover by removing two screws as shown below.
Page 7: Battery Connection
Battery Connection Lead-Acid Battery Connection WARNING: In order to operate safely and comply with laws and regulations, it is required to install an independent DC overcurrent protector or disconnect device between the battery and the inverter. WARNING: All wiring must be performed by a qualified personnel. WARNING: It's very important for system safety and efficient operation to use appropriate cable for battery connection.
Page 8: Lithium Battery Connection
Lithium Battery Connection If choosing lithium battery for the inverter, only lithium batteries that have been matched with BMS communication protocol are allowed. 1. Connect the battery according to the recommended battery cable specifications. 2. Insert the ring terminal of the battery cable into the battery connector of the inverter flatly, and ensure that the bolts are tightened with a torque of 2-3 Nm.
Page 9 PACE CAUTION: When the battery type is set to "LIB-485", the setting items 12, 13 and 29 are displayed in percentage. CAUTION: When the battery type is set to "LIB-485", the user cannot modify the maximum charging current. When communication fails, the inverter will cut off the output. When the SBU mode is selected in program 01, the battery SOC point for switching to the utility source...
