PRS300 Solar charge controller for 12V PV modules

The PRS300 solar charge regulator is suitable for photovoltaic moduleswith a total output of up to 300 W. It can be connected to the PT642(4300037/4300038) test panel, which displays the photovoltaic modules’charging current and the battery voltage. The PRS300 has three differentcharging characteristics (can be selected manually thanks to thecommutator). Ithas a battery desulfation function that is activatedautomatically only when the battery needs it. Four LEDS indicate whetherthe solar charge regulator is switched on, the current battery chargelevel and whether there is a faulty connection.

Red LED: This shows the potential reverse polarity (incorrectconnection) of the photovoltaic modules and/or the service battery.

White LED: This indicates that the charge regulator is switched on (inthe absence of sunlight, the regulator switches off automatically).

Yellow LED: This indicates that the photovoltaic modules are chargingthe battery (phase 1 and phase 2).

Green LED: This indicates the maintenance phase of the charging atconstant voltage (phase 3).

Dimensions: 115 x 90 x 37 mm
