Storing and long-term parking of your vehicle in winter
The battery is often removed or at least disconnected when a vehicle is put into
storage for the winter or is parked for an extended period. When doing this, please
make sure that you take into account the points below which relate to the use of
an automatic solar system.
E
Your SamYSolar+® system uses a microprocessor which, among other things,
continuously calculates the current sun position on the basis of the GPS data. Of
course, this requires a current in the region of a few mA. As you need to connect
the SamYSolar+® (just like all other solar charge regulators) directly to the battery,
the system will not be isolated from the switch by any isolating switch fi tted to the
battery circuit.
Accordingly, if you park your vehicle in a (naturally) dark garage for several week
or for the winter, the solar panel will not be able to recharge the battery at all, but
at the same time the electronics will still draw a very low current. We therefore re-
commend that, in this case, the battery should either be buffered with a designated
trickle-charging device, or it should be fully disconnected.
If you store your vehicle out in the open during the winter, then the SamYSolar+®
will keep recharging the battery during daylight hours by a small amount even
when it is in rest mode, so there should be no deep-discharging of the battery. Of
course you will need to turn off any other consumers, as the yield from the retrac-
ted solar panel is lower in winter than it is in summer. So, if you keep your vehicle
out in the open during the winter months, leave the SamYSolar+® system connec-
ted to the battery and switch it to rest mode.
