V.  1.1 

1. Introduction 

Thank you for purchasing the solar inverter. This simple solar inverter is designed to power 
your home appliances or precious 3C electronics. It also can handle motor-type loads with high 
surge power such as vacuums, small freezers, or drills. With built-in solar charger, it can 
convert solar power to battery power and provide continuous power to connected equipment 
during night time.     
 

2. Important Safety Warning (SAVE THESE INSTRUCTIONS) 

Before using the inverter, please read all instructions and cautionary markings 
on the unit, this manual and the batteries. 
General Precaution- 

Install the UPS in a protected area that is free of excessive dust and has adequate air flow. 
Please place the UPS away from other units at least 20 cm to avoid interference. Do NOT 
operate the UPS where the temperature and humidity is outside the specific limits. (Please 
check the specs for the limitations.) 

CAUTION!

 The unit is designed for indoor use. Do not expose this unit to rain, snow or 

liquids of any type. 

CAUTION! 

To reduce risk of injury, only use qualified batteries from qualified distributors or 

manufacturers. Any unqualified batteries may cause damage and injury. Do NOT use old or 
overdue batteries. Please check the battery type and date code before installation to avoid 
damage and injury. 

WARNING! 

It's very important for system safety and efficient operation to use appropriate 

external battery cable. To reduce risk of injury, external battery cables should be UL certified 
and rated for 7

  C or higher. And do not use copper cables less than 10AWG. Below is the 

external battery cable reference according to system requirements.
