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.
If the system has no grid/genset and the ISS 1Play has not a PV Input to start charging batteries, it will remain
stopped indefinitely.
However, in case that the installation has an additional PV inverter it is possible to start the ISS 1Play to
charge the battery from the PV inverter.
First of all it is needed to verify that the additional PV inverter has enough PV energy to start its production.
After that, it will be necessary to access:
"Emergency charge" function has been developed to start the ISS 1Play voltage generation for a short period
of time (5 minutes). This time should be enough for the additional PV inverter to detect this grid and to start
the current injection into it. Finally, once the system is correctly fed, the battery charge will run automatically.
Important note: ISS 1Play finds out automatically grid/genset or internal PV production in its input to charge
the batteries according to its configuration. The "Emergency charge" routine must be followed only when there
is no other option to start charging batteries from the ISS 1Play.
6.2 Manual equalization
6.2.1 I have a lead-acid battery and it has decreased its capacity, is there any option to
recover some capacity?
Not all lead-acid batteries support the equalization process. So first of all, check this point with the battery
manufacturer.
If it is allowed, there is a "Manual equalization" function to prevent the premature failure of individual battery
cells and extend the service life of the battery. It is located in the display in the following path:
This function launches a routine that will charge the battery in a certain moment following the steps below:
- Step1: Battery charges at constant current until it reaches the equalization voltage level.
Equalization step: The equalization process maintains the battery voltage to the "Equalization
-
Voltage" parameter during a "Equalization Time" parameter to recover batteries capacity.
Both parameters shall be configured in the ISS 1Play Battery Settings.
- Step2: Once that the equalization time is finished, the battery voltage keeps charging with the
"Absorption Voltage" parameter while the current starts to decrease. This step finishes when the
current is 1/8 of the configured "Charge Current" parameter.
- Step 3: The battery enters the floating phase, the charge process is finished and the SOC value is set
to 100%. It will remain there until the battery starts to discharge.
