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.
Technical Data:
20A charge regulator
MPPT algorithm with 12/24V autodetect,
LCD graphic display
RS485 interface
