3.2 Battery

3.2.1 As the minimum operation voltage is 40Vdc, is it possible to connect a 40Vdc battery?

It is highly not recommended due to the fact that during their discharge cycle batteries decrease their voltage,
in case that the voltage was under 40Vdc the device will stop working. In conclusion, the battery bank shall be
into proper voltage ranges (extended operating voltage, see "Installation and Operation Manual").
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.
It is completely necessary to set the battery bank properly to avoid the possibility of an under-40 volts
situation. In Lead-Acid batteries for example the minimum nominal voltage needed will be 48Vdc. This value
takes in consideration that the battery during its discharge cycle could reach the limit depending on the depth
of the discharge.
3.2.2 If we have a battery voltage higher than the specified in the storage system voltage
range, can we connect it to the ISS 1Play?
There are 2 different battery voltage ranges depending on whether the PV Input is being used or not. In any
case the battery voltage range could exceed those ranges.

3.2.3 I have an AGM battery, how should I configure it?

AGM batteries are fully compatible with lead-acid configuration as they are a type of them. Unlike common
lead-acid batteries that have their electrolyte flowing free inside the battery, the electrolyte in these AGM
(Absorbent Glass Mat) batteries is held in fine glass mats, where its name comes from.
AGM batteries usually do not include an equalization value in their datasheet due to the fact that they are
sealed, not allowing that phase. Only absorption and floating voltage values are considered.
Note: It is very important to verify, as done with all Lead-Acid batteries, that all the configuration values have
been included correctly.

3.2.4 SOC parameter has suddenly jumped to 100%, is it possible?

SOC parameter is used to show the battery remaining charge. SOC value is estimated for Lead-Acid batteries
using many factors, the most important are the discharge current capacity for 20 and 5 hours (C20h and C5h).
The algorithm used to calculate the SOC value may produce jumps in the value due to its own computation
process, so it could be perfectly normal seeing those big steps for example in EMS Tools graphs as shown in
the next figure:
