  • Page 5: Introduction And Purpose

    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.

    INGECON SUN STORAGE 1Play 2 Definitions 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.

  • Page 9: Electric Power Systems (Ac)

    INGECON SUN STORAGE 1Play 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.
  • Page 10 INGECON SUN STORAGE 1Play 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.
  • Page 11 INGECON SUN STORAGE 1Play IT Network In an IT network, there is no connection to earth at the distribution point, or there is a connection with very high impedance. So, it is isolated. The bodies of the electrical devices are connected to the Local Earth Electrode.

    3.1.3 In a stand-alone system, could the ISS 1Play work with other Ingeteam PV inverters? Yes, it could be possible in a 2 to 1 power ratio, meaning that the sum of added PV inverters will not exceed the double of the ISS 1Play stated power.

    INGECON SUN STORAGE 1Play Figure 9: Dual-pitched installation Connecting the whole PV installation to the ISS 1Play will decrease the efficiency of the whole system, but anyway this solution will be more inexpensive rather than installing two ISS 1Play or an ISS 1Play and an additional Sun 1Play.

  • Page 14: Battery

    The choice of the battery bank is one of the most important tasks to achieve a correct performance from the ISS 1Play. Ingeteam’s device has been designed to work with a minimum battery voltage of 40 volts, which means that if the battery during its discharging cycle goes under that voltage, the device will stop working.

  • Page 15: While Taking Energy From The Batteries, Which Are The Main Power Limitations In The Iss 1Play

    INGECON SUN STORAGE 1Play Figure 10: SOC step During the SOC calculation process, the SOC parameter is set to certain specific values at two points: 1. 85%, when the charging current in the step 2 (absorption) decreases until the 1/3 of the configured charging current.

  • Page 16: Can Inverter Measure Mid-Point Voltage Of Battery Bank

    3.2.7 I have a Lithium battery, how should I configure it? Lithium-ion batteries suitable for operation with the INGECON SUN STORAGE 1Play have their own advanced battery management, usually programmed by the manufacturer and built into the batteries (BMS).

  • Page 17: Pv Modules

    INGECON SUN STORAGE 1Play 3.3 PV modules 3.3.1 If the available energy of PV modules is greater than the load’s need, where is extra energy going? Even if the ISS 1Play is configured to not injecting to grid, it will not be any excess of energy because the inverter inside the ISS 1Play will automatically regulate itself changing the MPPT configuration and just taking the needed energy from PV modules.

  • Page 18: In A Grid Connection System, How Is The Extra Pv Inverter Controlled

    3.3.4 In a grid connection system, how is the extra PV inverter controlled? First of all it shall be checked that the PV inverter is an Ingeteam device, as shown in 3.1.3 only Ingeteam inverters can be used to work in a common strategy and communication with the ISS 1Play.

  • Page 19: Ac Grid / Generator

    For identifying the systems, see the definition section “2.2 - Electric Power Systems (AC)”. For more information, see the “Installation and Operation Manual” of the Ingecon Sun Storage 1Play. 3.4.2 Does the ISS 1Play have any surge arrestors to protect from AC over-voltages? The ISS1 Play does not have surge arrestors but it includes varistors in the AC side.

  • Page 20: Loads

    INGECON SUN STORAGE 1Play 3.5 Loads 3.5.1 Having grid and loads of 10kW, is it possible to feed them with an ISS 1Play? How the installation should be? Yes, it is possible because the both the AC Grid Port and the AC Loads Port are limited to 11.5 kW. However, the ISS 1Play will be able to provide the Output (AC) Rated Power from the Battery or/and PV Input.

  • Page 21: Communications

    INGECON SUN STORAGE 1Play 3.6 Communications 3.6.1 Is Bluetooth available in ISS 1Play? No, it is not. Bluetooth has been discontinued. 3.6.2 When having an alarm in the ISS 1Play, is it possible to receive notifications? It is possible installing the INGECON SUN EMS Board.

  • Page 22: Measured Pv Voltage Is Over 0Vdc At Night Or Even Without Pv Modules' Connection, How Is It Possible

    INGECON SUN STORAGE 1Play 3.7.2 Measured PV voltage is over 0Vdc at night or even without PV modules’ connection, how is it possible? This happens because PV input is directly connected to the DC-bus. When there is not enough voltage from PV modules to generate the desired AC voltage, the voltage value shown on the display will be the DC-bus voltage and it is the only PV voltage sensor.

  • Page 23: Operation Mode

    INGECON SUN STORAGE 1Play 4 Operation mode 4.1 General 4.1.1 Which parameter is used to inject extra PV power to the grid? The parameter to configure is GRID POWER. To let the ISS 1Play inject the extra PV energy to the grid, “GRID POWER”...
  • Page 24 INGECON SUN STORAGE 1Play Charging Power: This parameter is not used in “Grid Support” mode. Anyway, it is recommended to set this value to 0 W. 24/29 Technical Guide 10/11/2017...

  • Page 25: Configuration

    Important note: if the charge/discharge current is not specified in the datasheet, the value shall be asked to the manufacturer in order to get a suitable current. A wrong configuration of this parameter may cause damage to the battery bank and to the ISS 1Play. Ingeteam will not accept any responsibility of any wrong configuration.

  • Page 26: Inverter

    INGECON SUN STORAGE 1Play 5.2 Inverter 5.2.1 How should be configured the nominal voltage and frequency values? AC Voltage and Frequency parameters have different purpose for on-grid or off-grid situations: In grid-connection systems: Those values must be the nominal values of the utility grid.

  • Page 28: More Options

    INGECON SUN STORAGE 1Play 6 More Options 6.1 Emergency charge from an external PV Inverter 6.1.1 There is no grid/genset but I have an additional PV inverter, is it possible to charge the batteries with the ISS 1Play from the PV inverter? When the ISS 1Play has reached the SOCdescx or the minimum voltage (Alarm=0x0001 and Code2=0x0080) stops.

  • Page 29: Start/Stop Lithium Battery

    INGECON SUN STORAGE 1Play Figure 17: Equalization process Important note: As seen on the graph, the battery will be exposed to a higher voltage than usual, so it is very important to ensure before using the “Manual equalization” that the battery is fully compatible with this option.
