WRM20 is a complete solution for off-grid PV systems to supply power to road signs systems, lighting systems, small low voltage systems and batteries inside caavans. This model of charge regulator has a circuit for the research of the maximum PV module power (MPPT): regardless ofthebattery voltage and its charge status, WRM20 works withthe PV module in its maximum power point,maximizing the energy thatcomes from the module and then is loaded into the battery.
