Thanks to AL-KO Vehicle Technology Electronics the sun's power is under control

The charging regulator is an indispensable instrument when it comes to correct motorhome photovoltaic installation operation. The CBE catalogue – brand of the AL-KO Vehicle Technology Electronics Group – includes an entire range of these devices, to be calibrated according to the power and number of photovoltaic cells in the system and the current to be managed.

The new solar regulator PRS350 is designed and built with innovative electronic technologies, characterised by high electrical efficiency and very low heat dissipation. PRS350 is suitable for the connection of photovoltaic modules for up to a maximum total power of 350 W, and can be connected to test panel PT742, for the control of battery charging and voltage.

The PRS350 regulator has four different charging profiles, including a specific one for lithium batteries, selectable by means of a specific switch. A battery desulphation refreshment function (for traditional AGM lead/gel models with the exclusion of the charging profile for lithium) automatically activates if necessary, to maximise battery duration. The four LEDs on the device provide information on the battery's state of charge, upon device switch-on, solar activation and in the event of any incorrect connection.

Fitted with two inputs for 12 V photovoltaic modules with a maximum rated voltage of 27 V in open circuit, it issues an output current of up to 20 A. Maintenance voltage varies from 13.5 to 13.8 V, according to the type of battery, whereas the end-of-charge voltage oscillates between 14.1 and 14.7 V, once more according to the selected profile and type of accumulator. The regulator ensures automatic switch-off in the absence of sunlight, thus zeroing absorption in self-consumption. The electronics are protected by the block for inverse current and polarity inversion.

The new regulator PRS350, together with all the latest innovations in the CBE catalogue, will be presented for the first time to the public at the Caravan Salon in Düsseldorf, from 25th August 2023, at the company's stand in Hall 14/Stand A6
