For safety operation and regulation compliance, it’s requested to install a separate DC
over-current protector or disconnect device between battery and inverter. It may not be
requested to have a disconnect device in some applications, however, it’s still requested to
have over-current protection installed.
All wiring must be performed by qualified personnel.
It's very important for system safety and efficient operation
to use appropriate cable for battery connection. To reduce
risk of injury, please use the proper recommended cable and
terminal size as below.

Note:
For lead acid battery, the recommended charge current is 0.2C (C
Æ battery capacity).
Please follow below steps to implement lead-acid battery connection
a. Assemble battery ring terminal based on recommended battery cable and terminal size
(Same as Lead acid, see section 3.3.2 for details).
b. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the
bolts are tightened with a torque of 2-3Nm.Make sure polarity at both the battery and the inverter is
correctly connected and ring terminals are tightly screwed to the battery terminals.
Figure 3-7
WARNING:
CAUTION:
Shock Hazard
Installation must be performed with care due to high battery voltage in series.
Do NOT place anything between the flat part of the inverter terminal and the ring
terminal. Otherwise, overheating may occur.
Do NOT apply anti-oxidant substance on the terminals before terminals are
connected tightly.
Before making the final DC connection or closing DC breaker, be sure positive (+)
must be connected to positive (+) and negative (-) must be connected to negative (-).

CPS5000ECH48-P can be used in parallel operation in single phase with up to 3 units. The following
items were used, if you need parallel function.

Figure 6.3
CAUTION:
6.3 Parallel installation in single phase
You need to connect the cables of each inverter together. Take the battery cables for example: You
need to use a connector or bus-bar as a joint to connect the battery cables together, and then connect to
the battery terminal. The cable size used from joint to battery should be X times cable size of each
inverter. “X” indicates the number of inverters connected in parallel. Regarding AC input and output,
please also follow the same principle.
Contents of this chapter were applied to CPS5000ECH48-P only.
For proper air circulation to dissipate heat, allow a clearance of approx. 300mm to the
side and approx. 500mm above and below the unit. Be sure to install each unit in the
same level

CPS5000ECH48-P 100A/60VDC
If you want to use only one breaker at the battery side for the whole system, the rating of the breaker
should be X times current of 1 unit. “X” indicates the number of inverters connected in parallel. But we
suggest that each inverter has a battery breaker. It will be safer.

Model Name 1 unit 2 units 3 units
CPS5000ECH48-P 40A/230VAC 80A/230VAC 120A/230VAC
Also, you can use 40A breaker for only 1 unit, and each inverter has a breaker at its AC input/output L line.
WARNING:
Be sure that all inverters will share the same battery bank. Otherwise, the inverters
will transfer to fault mode.
Be sure the length of all battery cables is the same. Otherwise, there will be voltage
difference between inverter and battery to cause parallel inverters not working.
Please install the breaker at the battery and AC input/output side. This will ensure the
inverter can be securely disconnected during maintenance and fully protected from
over current of battery or AC input/output. The recommended mounted location of
the breakers is shown in the figures in 6.4 and 6.6.
Unobstructed connections for all inverter’s AC input/output N lines.
Please ensure that the L&N order for each machine is consistent. Otherwise, the
inverter may be damaged.

9 Trouble Shooting
Problem Explanation/
Possible cause What to do
Unit shuts down automatically
during startup process. The battery voltage is too low 1. Re-charge battery. 2. Replace battery.
No response after power on.
1. The battery voltage is far
too low.
2. Battery polarity is
connected reversed.
1. Check if batteries and
the wiring are connected
well.
2. Re-charge battery.
3. Replace battery.
Mains exist but the unit works in
battery mode.
Input protector is tripped
Check if AC breaker is
tripped and AC wiring is
connected well.
Insufficient quality of AC
power. (Shore or Generator)
1. Check if AC wires are
too thin and/or too long.
2. Check if generator (if
applied) is working well or
if input voltage range
setting is correct.
(Appliance)
Set “Solar First” as the
priority of output source.
Change output source
priority to Utility first.
When the unit is turned on,
internal relay is switched on and
off repeatedly.
Battery is disconnected. Check if battery wires are
connected well.
