User Manual 3 / 54 CPS Mini Central series

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 4 / 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.

 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.

minimize risk of accidents.

 The CPS Mini Central series may only be operated with PV generators

(modules and cabling) with protective insulation. Do not connect any source

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.

5.4.3 Wiring DC Input

Danger to life due to hazards voltages!

Before connecting the PV array, ensure that the DC switch and AC breaker are disconnect from the inverter. NEVER connect or disconnect the DC connectors under load.

Improper operation during the wiring process can cause fatal injury to operator or unrecoverable damage to the inverter. Only qualified personnel can perform the wiring work.

Risk of damage to the inverter. If the voltage of the PV modules exceeds the maximum input voltage of the inverter, it can be destroyed by the overvoltage. This will void all warranty claims. Do not connect strings to the inverter that have an open-circuit 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.

Excessive DC voltages can destroy the measuring device Only use measuring devices with a DC input voltage range up to at least 1,000 Vdc.

*Relate only to transformerless installation.

1 Check the connection cables of the PV modules for correct polarity and make sure that the maximum

6.2 Operation Modes

Normal Mode

In this mode, the inverter works normally and LED turns green.

 Whenever the DC voltage is higher than 300Vdc, inverter converts power to grid as generated by the PV

panels;

 Whenever the DC voltage is lower than 250Vdc, the inverter will work in waiting state and attempt to

connect the grid. In waiting state the inverter consumes just enough power generated by the PV panel to

monitor the internal system.

Notes: The inverter starts up automatically when DC power from the PV panel is sufficient.

Fault Mode

The internal intelligent controller can continuously monitor and adjust the system state. If inverter finds any

unexpected conditions such as system fault and inverter fault, the fault information will be displayed on the LCD. In

fault mode the LED turns red.

6.4 Double MPPT of the CPS Mini Central

The CPS Mini Central includes dual input section to process eight strings with independent MPPT, high speed and

precise MPPT algorithm for real-time power tracking and energy harvesting, as well as transformerless operation

for high performance, the max conversion efficiency is up to 98.2%. The wide input voltage range makes the

inverter suitable to low power operation as well as the high power operation.

As the weather influence and the location of two MPPT PV arrays different, the power of the MPPT A inputs is

different from the power inputs of the MPPT B at the same time, the CPS Mini Central works at a non-symmetrical

input state. But the MPPT algorithm of the inverter makes it tracking the maximum power point of each MPPT

channel to improve the energy utilization of the PV arrays.

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.

1. Please disconnect the DC and AC connection.

 Turn off the DC switch.  Disconnect the DC terminal. (You might need some tool to disconnect the male and female

terminals)

 Disconnect the AC terminal.

2. Remove the protecting plants at the bottom of inverter.

Remove the inverter from mounting bracket, and place inverter horizontally on clean and dry place.

3. Screw off the screws to open the cover with suitable tool, then fans will be seen, as figures below:

Fig 8.1.5

4. Pull out the white connectors with some tinny tools.

6. When finishing cleaning, put back the fans in reverse order.

8.2 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 8.1 Cleaning Cooling Fan and Grill (Step 1 ~ 6), step 7 should be exchanging the fans and

assembling the inverter in reverse order.
