Explanation / Possible cause
The battery voltage is too low
( < 1.91V/Cell)
1. The battery voltage is far too low.
(<1.4V/Cell)
2. Battery polarity is connected
reversed. Input protector is tripped
1. Re-charge battery.
2. Replace battery.
1. Check if batteries the wiring
are connected and well.
2. Re-charge battery.
3. Replace battery.
Check if AC breaker is tripped
Input protector is tripped
and AC wiring is connected
well.
1. Check if AC wires are too
thin and/or too long.
Insufficient quality of AC power
(Shore or Generator)
2. Check if generator (if
applied) is working well or if
input voltage range setting is
correct.(Appliance=>wide)
Battery is disconnected.
Overload error. The inverter is
overload 110% and time is up.
Check if battery wires are
connected well.
Reduce the connected load by
switching off some equipment.
Check if wiring is connected
Output short circuited.

load.
Check whether the air flow of
Internal temperature of inverter
component is over 90 C.
o
Battery is over-charged.
The battery voltage is too high.
the unit is blocked or whether
the ambient temperature is too
high.
Return to repair center.
Check if spec and quantity of
batteries are meet
requirements.

Output abnormal (Inverter voltage
below than 202Vac or is higher than
253Vac)
Internal components filed.
Over current or surge
Bus voltage is too low
Output voltage is unbalanced
Battery is not connected well or
fuse is burnt.
1. Reduce the connected load.
2. Return to repair center
Return to repair cente
Restart the unit, if the error
happens again, please return
to repair center.
If the battery is connected well,
please return to repair center.
What to do
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

The following cases are not within the scope of warranty
1. Out of warranty.
2. Series number was changed or lost.
3. Battery capacity was declined or external damaged.
4. Inverter was damaged caused of transport shift, remissness, ect external factor
5. Inverter was damaged caused of irresistible natural disasters.
6. Not in accordance with the electrical power supply conditions or operate environment caused damage.
SAFETY INSTRUCTIONS
WARNING: This chapter contains important safety and operating instructions. Read and keep
this manual for future reference.
1. Before using the unit, read all instructions and cautionary markings on the unit the batteries and all appropriate
sections of this manual.
2. 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.
3. Do not disassemble the unit. Take it to a qualified service center when service or repair is required. Incorrect
re-assembly may result in a risk of electric shock or fire.
4. To reduce risk of electric shock, disconnect all wirings before attempting any maintenance or cleaning. Turning
off the unit will not reduce this risk.
5. CAUTION --Only qualified personnel can install this device with battery.
6. NEVER charge a frozen battery.
7. 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.
8. 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.
9. 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.
10. Fuses (1 piece of 200A, 58VDC for 3KW,4KW and 5KW) are provided as over-current protection for the battery
supply.
11. 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.
12. NEVER cause AC output and DC input short circuited. Do NOT connect to the mains when DC input short circuits.
13. Warning!! Only qualified 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.
