1 Introduction and purpose

The present document is intended to be a guide to solve the most frequently asked questions that will appear

to both, user and installer, during INGECON SUN STORAGE 1Play (hereinafter, ISS 1Play)start up, operation

and maintenance actions.

As the device continues its development and continuous improvement, new questions will be added in order

to keep it updated.

The most common doubts and problems have been summarized here and classified depending on its origin.

2.1 ISS 1Play Internal Schema and Connections

Figure 1: ISS 1Play Schema

A. Storage system: Connection point between the DC/DC converter and the batteries. The storage

system is compound of a battery bank; the batteries in the bank can be of Lead-Acid or Li-ion.

B. PV input: Coupling point between the PV modules and the DC-bus.

Figure 3: PV input

D. Consumption grid relay: Relays used to isolate the inverter from the grid or the loads. When closed,

these relays connect the inverter to the loads.

E. Grid or auxiliary generator relay: Relays used to disconnect the grid from the ISS 1Play and the loads.

When closed, these relays create a bypass joining grid and loads.

F. Auxiliary grid/genset input: Connection point between the ISS 1Play and the grid.

It is very important to know the configuration of the installation where the ISS 1Play will be connected

to, including the electric power system type. More information about them is included in 2.2.

Figure 4: Grid / Genset input

G. Consumption grid output: Coupling point between the ISS 1Play and the loads.

As in the previous point, it is very important to know the type of the installation that will join the loads

to the ISS 1Play. Further information is shown in 2.2.

2.2 Electric Power Systems (AC)

2.2.1 Number of Phases

Single phase electric power system: power system used for distribution of energy where there are a line

and a neutral (in some systems earth acts as the neutral). The line carries the current which varies its

amplitude in a 50/60 Hz frequency, feeds the load and finally returns to the source by the neutral. The

available values for the ISS 1Play are between 200 and 250 Volts, they should fit to the grid depending on

each country’s standard too.

A simple single phase system is included in the figure below:

Figure 6: Single phase system

Three phase electric power system: Despite the fact that in the past there were sold some ISS 1PLAY to

create a three phase power system, currently this solution has been discontinued.

2.2.2 Earthing or Grounding System

Earthing or grounding specific parts of an installation is common practice done in the low voltage distribution

networks for safety and functional purposes. The safety ones are basically to protect a person against electric

shocks.

There are several ways to do it, but International standard IEC 60364 distinguishes three families of earthing

arrangements, using the two-letter codes TN, TT, and IT.

The first letter indicates the connection between earth and the power-supply equipment (generator or

transformer):

"T" —Direct connection of a point with earth (Latin: terra)

"I" —No point is connected with earth (isolation), except perhaps through a high impedance.

The second letter indicates the connection between earth or network and the electrical device being supplied:

"T" —Earth connection is by a local direct connection to earth (Latin: terra), usually via a ground rod.

"N" —Earth connection is supplied by the electricity supply Network, either as a separate protective

earth (PE) conductor or combined with the neutral conductor.

The network system used in your installation must be identified because the ISS 1Play can only work towards

some network types.

TT Network

In a TT system, there is a connection to the earth in the grid distributor´s transformer, usually the star point of

a three-phase system. However, it is provided a connection to the local earth electrode. As the fault loop

impedance is usually high, those systems should always have a Residual Current Detector.

Figure 7: TT system

TN Network

In a TN system, as in TT systems, there is a connection in the grid generator´s transformer to Earth. However,

the bodies of the electrical devices are connected to a so called Protective Earth wire. This wire is related to

the Neutral wire, but depending on the connection point, three variants are distinguished:

TN-C Network

A combined conductor fulfills the functions of both PE and Neutral wires. This combined wire is called PEN.

TN-S Network

PE and N are separate wires from the distribution point.

TN-C-S Network

PE and N come combined from the distribution point, but they are separated (usually at the building

distribution point) before getting to the consumer.
