- The device shall be used for the regulation of 12V photovoltaic modules charging only.
Connection to other equipment which can damage its correct operation may result in
warranty void.
- The regulator must be exclusively used with the types of batteries listed above. The kind of
battery to charge shall be set on the solar regulator internal board using the apposite
selector (see page 8); the wrong setting of the battery to charge may damage the battery
itself!
: the PRS300 regulator is not suitable for the charging of nickel/cadmium batteries,
lithium batteries without integrated electronics or other kinds of rechargeable or non
rechargeable batteries.
- The regulator is not suitable for external use.
- Install the regulator in an appropriate dry and ventilated housing; make sure there is a
minimum distance of 300mm from the front and 100mm from the sides of the device to the
surrounding surfaces.
- Do not cover the air intakes on the lid.
- The device produces heat during its normal operation. Make sure that the installation of other
equipment near the instrument does not hamper the correct air flow and prevent the
necessary instrument cooling.
- Use cables with an appropriate section (a 6mm²
for
photovoltaic module
).
- Protect the cables from any possible damage.

The PRS300 charge regulator can automatically charge the following 12V
battery types
using the correct charge line (which can be selected with the switch placed inside the
regulator): lead-gel, lead-acid, AGM and lithium batteries (with integrated electronics).
The charging procedure occurs in three steps:
Step 1:
with the maximum current of the photovoltaic module, until the end of
charge voltage is reached.
Step 2:
at the end-of-charge voltage with
.
Step 3:
at a constant voltage.
The cycle starts again when the battery voltage is lower than 13Vd.c., such as in the case of
equipment turning on.
an uneven exposure to sunlight may lead to varying charging times.

A desulfation function is automatically activated when required by the battery.
Generally, the selector should be set on position

for
lead-gel batteries, and position

NOTE:
the end-of-charge voltage is reached only if the batteries are efficient.
