mer temperatures, which accelerate part ageing. Normally the battery
average lifetime is approx. 4-5 years; this also depends on the intensity of
automation use.
SYA1 battery charger
Refer to the specific chapter in device instruction manual.

VERY IMPORTANT:
- When the automation is powered by the "Solemyo" system, it must
never be connected or powered simultaneously by the electrical
mains.
- The devices SYP and SYA1, which supply energy to PSY24, are alter-
natives and cannot be used simultaneously.
• for photovoltaic power supply (with SYP)
Graphs A, B and C indicate the solar power available, on the basis of the
location's latitude, at all times of the calendar year, with the automation pow-
ered exclusively using PSY24 and SYP devices. The graph curve is generat-
ed taking into account the quantity of daylight recorded at a specific latitude
within a year.
To obtain the maximum possible number of cycles per day, proceed as fol-
lows:
01. On graph A, B or C (depending on the latitude of your system) identify
the period of the year concerned, then locate value "Cb" on the vertical
axis, corresponding to this period, as shown in the example in the
graph.
02. Then use value "Cb" to make the calculations as stated in the sheet in
the product pack.
Warning – During the day, if the photovoltaic panel remains in the shade
for a certain period of the day (in particular from 10 am to 2 pm) the maxi-
mum possible number of operating cycles decreases in proportion to the
hours without panel exposure to sunlight.
Warning – To increase the maximum possible number of cycles per day,
automation consumption must be reduced. For this reason, the "Standby"
function must be programmed on the automation control units, setting the
most efficient level (refer to the automation instruction manual).
• for mains power supply (with SYA1)
The PSY24 battery must be recharged via the mains in a protected environ-
ment, previously detaching PSY24 from the SYP solar panel and the
automation.
