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.

User Manual 5 / 43 CPS Mini Central series

 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 frame and the PV generator.

CyberPower strongly recommends grounding the generator frame in order to have optimal earth protection to PV generating system and personnel.

 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 both indoors and outdoors.

 You can use the AC current generated as follows:

House grid:

Energy flows into the house grid. The consumers consume the energy with household devices or lighting. The left energy 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 wattmeter spins backwards. Note that the wattmeter should be bi-direction type under such application.

Public grid:

Energy is fed directly into the public grid. The CPS Mini Central series need install a separate wattmeter.

 Ensure all covers and doors are closed and secure during

operation.

 Although designed to meet all safety requirements, some parts

and surfaces of Inverter are still hot during operation. To reduce the risk of injury, do not touch the heat sink at the back of the PV-Inverter or nearby surfaces while Inverter is operating.
