2. Safety
2.1 Intended Use
CPS Mini Central series inverters are to be used solely to feed solar energy converted
photovoltaically into the public grid. CPS Mini Central series inverters are multi-string
inverters with multi-MPP trackers, which mean they are able to connect to different PV
module arrays. The equipment may only be operated in compliance with its intended use.
Grid-tied PV system Overview:
Fig2.1
The inverter may only be operated with a permanent connection to the public power
grid. The inverter is not intended for mobile use. Any other or additional use is not
considered as intended use. The manufacturer is not responsible for any damages resulting
from unintended use. Damage caused by such unintended use is at the sole risk of the
operator.
As drawings shown above, a complete Grid-tied PV system consists of PV modules, PV
inverters, public grid and other components. Moreover, PV inverters always act as key
components.
PV modules Capacitive Discharge Currents:
PV modules with large capacities relative to earth, such as thin-film PV modules with
cells on a metallic substrate, may only be used if their coupling capacity does not exceed
5000nF. During feed-in operation, a leakage current flows from the cells to earth, the size of
which depends on the manner in which the PV modules are installed (e.g. foil on metal roof)
and on the weather (rain, snow). This "normal" leakage current may not exceed 300mA due
to the fact that the inverter would otherwise automatically disconnect from the electricity
grid as a protective measure.
If PV modules of the PV system require POSITIVE or NEGATIVE
grounding, , please contact CyberPower Systems, Inc. for technical
support before installation.

voltage greater than the maximum input voltage of the inverter.
To reduce the risk of electric shock, avoid touching the live
components and treat the terminals carefully.
The PV modules should have an IEC61730 Class A rating*.
Please use the same brand male and female PV connectors.
Under any conditions the total circuit current should never
exceed the Max. Current.
*Relate only to transformerless installation
Check the assembled DC connectors for correct polarity and connect them to the
inverter.
Check the connection cables of the PV modules for correct polarity and make sure that
the maximum open circuit voltage of each string should never exceed 1000V.
In order to optimize the system configuration, the two inputs are recommended to be
connected to the same number of PV modules.
The maximum short circuit current of each PV string is no more than 12A under any
conditions.
In order to secure the inverter from water and dust, all unused DC inputs must be closed
with sealing plugs.

11. Maintenance and Cleaning
Once the output power is derating because of too high warming, some tips can help you
solve such problems:
The air grills or cooling fans are clogged. To clean the air grills and cooling fans please
refer to 11.1 Cleaning Fans and Grills.
One or two cooling fans failed. To exchange the cooling fans please refer to 11.2
Exchanging Fans.
Ventilation of installation location is poor. Choose appropriate installation location
before mounting.
11.1 Cleaning Fans and Grills
Maintain fans and grills every half a year to reduce the power derating caused by
excessive heat.
If fans or grills are just covered by soft dust particles, using tools such as vacuum cleaner
to clean the fans. And if user has no such tools or there are obstructions in fans, grills or the
cooling area of inverter, you need to clean the fans and grills after they are took apart from
the inverter.
Fan cleaning and exchange procedure:
Step 1: Please ensure that the DC side and AC side of the inverter have been disconnected.
Turn off the DC side switch
Disconnect the DC terminal. (You might need some tool to disconnect the male and
female terminals)
Disconnect the AC terminal.
Step 2: Screw off the screws to open the cover with suitable tool, then fans will be seen, as
figures below:
Fig11.1
Step 3: Pull out the white connectors with some tinny tools.

Fig11.2
Step 4: Take away the fans from the cover and clean them thoroughly.
Fig11.3
Step 5: When finishing cleaning, put back the fans in reverse order.
11.2 Exchange Fan
Sometimes the heat dissipation error occurred because the cooling fans failed, under
such situation, you need to exchange the cooling fans.
The procedure is similar to 11.1 Cleaning Cooling Fan and Grill (Step 1 ~ 5), step 6 should
be exchanging the fans and assembling the inverter in reverse order.
11.3 Exchange Fuse
Fuse exchange procedure:
Step 1: Please ensure that the DC side and AC side of the inverter have been disconnected.
Turn off the DC side switch
Disconnect the DC terminal. (You might need some tool to disconnect the male and
female terminals)
