In Stand-Alone Operation Mode, How Is It Possible To Have Grid Alarms? (Alarms: 0X0002; 0X0004; 0X0006) - Ingeteam INGECON SUN STORAGE 1Play Technical Manual

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. The additional cost of a second inverter will not be taken by the power gain benefits.
3.1.6 In stand-alone operation mode, how is it possible to have grid alarms? (Alarms:
0x0002; 0x0004; 0x0006)
Stand-alone operation mode is intended to work completely away from grid, so grid alarms like 0x0002 (grid
frequency out of range), 0x0004 (grid voltage out of range) or 0x0006 (grid frequency and voltage out of
range) would have no meaning.
This is completely true while working with batteries on a higher SOC than SOCmin. When SOC reaches the
value of SOCmin, the ISS 1Play will automatically start looking for a genset to take energy from it, during this
process, if no genset is found, a grid related alarm will appear.
In case that there were no genset and a lower SOC than SOCmin, this alarm is completely normal and the
device will not stop working while SOC>SOCdescx. It is important to know that not every alarm will stop the
ISS 1Play.
