1. About this manual
1.1 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.
1.2 Scope
This manual provides safety and installation guidelines as well as information on tools and
wiring.

. 7 .
2. Safety instructions
2.1 Safety standards
This chapter contains important safety and operating instructions. Read and keep this manual
for future reference.
• Before using the unit, read all instructions and cautionary markings on the unit, the batteries
and all appropriate sections of this manual.
Caution.
To reduce risk of injury, charge only deep-cycle lead acid type rechargeable batteries.
Other types of batteries may burst, causing personal injury and damage.
• Do not disassemble the unit. Take it to a qualied service center when service or repair is
required. Incorrect re-assembly may result in a risk of electric shock or re.
• To reduce risk of electric shock, disconnect all wirings before attempting any maintenance or
cleaning. Turning off the unit will not reduce this risk.
Caution.
Only qualied personnel can install this device with battery.
Caution.
Never charge a frozen battery.
• For optimum operation of this inverter/charger, please follow required spec to select
appropriate cable size. It’s very important to correctly operate this inverter/charger.
• Be very cautious when working with metal tools on or around batteries. A potential risk exists
to drop a tool to spark or short circuit batteries or other electrical parts and could cause an
explosion.
• Please strictly follow installation procedure when you want to disconnect AC or DC terminals.
Please refer to INSTALLATION section of this manual for the details.
• Fuses are provided as over-current protection for the battery supply.
• GROUNDING INSTRUCTIONS -This inverter/charger should be connected to a permanent
grounded wiring system. Be sure to comply with local requirements and regulation to install
this inverter.
• NEVER cause AC output and DC input short circuited. Do NOT connect to the mains when
DC input short circuits. .
Warning. Only qualied service persons are able to service this device. If errors still
persist after following troubleshooting table, please send this inverter/charger back to
local dealer or service center for maintenance.
Warning. Because this inverter is non-isolated, only three types of PV modules are
acceptable: single crystalline, poly crystalline with class A-rated and CIGS modules. To
avoid any malfunction, do not connect any PV modules with possible current leakage
to the inverter. For example, grounded PV modules will cause current leakage to the
inverter. When using CIGS modules, please be sure NO grounding.
Caution. It’s required to use PV junction box with surge protection. Otherwise, it will
cause damage on inverter when lightning occurs on PV modules.
