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:
Fig 1.1
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 470nF. 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 50mA due to
the fact that the inverter would otherwise automatically disconnect from the electricity grid as a protective
measure.

User Manual 5 / 54 CPS Mini Central series
If PV modules of the PV system require POSITIVE or NEGATIVE to connect
to GROUND, or the capacitance relative to ground of the modules is
large, please contact CyberPower Systems, Inc. for technical support
before installation.
2.2 Safety Precautions
The CPS Mini Central series is designed and tested according to international safety requirements; however, certain
safety precautions must be observed when installing and operating this inverter. Read and follow all instructions,
cautions and warnings in this installation manual.
2.3 Assembly Warnings
Prior to installation, inspect the unit to ensure absence of any
transport or handling damage, which could affect insulation integrity
or safety clearances; failure to do so could result in safety hazards.
Unauthorized removal of necessary protections, improper use,
incorrect installation and operation may lead to serious safety, shock
hazards or equipment damage.
In order to minimize the potential of a shock hazard due to hazardous
voltages, cover the entire solar array with dark material prior to
connecting the array to any equipment.
Grounding the PV modules: Comply with the local requirements for
grounding the PV modules and the PV generator.
CyberPower recommends connecting the generator frame and
other electrically conductive surfaces in a manner which ensures
continuous conduction and ground these in order to have optimal
protection of the system and personnel.

of energy other than PV modules to the CPS Mini Central series.
Systems with inverters typically require additional control (e.g., switches,
disconnects) or protective devices (e.g., fusing circuit breakers) depending
upon the prevailing safety rules.
Please read this manual carefully, the manufacturer or supplier is not
responsible for damage caused by incorrect operation, installation, wiring,
transport, etc.
The CPS Mini Central series is to be used solely to feed solar energy
converted photovoltaic into the public grid. The inverter is suitable for
mounting indoors and outdoors.
You can use the AC current generated as follows:
House
grid:
Energy flows into the house grid. The consumers connected,
for example, household devices or lighting, consume the
energy. The energy left over is fed into the public grid. When
the CPS Mini Central series do not generate any energy, e.g., at
night, the consumers which are connected are supplied by the
public grid. The energy displayed on the LCD of inverter is for
reference only. When energy is fed into the public grid, the
energy meter spins backwards.
Public grid:
Energy is fed directly into the public grid. The CPS Mini Central
series need install a separate energy meter. The energy
produced is compensated at a rate depending on the electric
power company.
