The new ProStar Gen3 PWM charge controllers are Morningstar’s third generation of their highly reliable mid-range PWM solar charge controllers for residential, mobile, or stand-alone power and lighting systems. They feature conformally a coated circuit board, corrosion-resistant terminals, and automatic battery select for 12 and 24 VDC systems. 4-stage charging for Bulk, Absorption, Float, and Equalizing, with 7 standard battery settings, or custom settings can be programmed in. Full nameplate current rating, both PV and load, up to 60 C continuous.
The ProStar Gen3 controllers provide continuous self-diagnostics, monitoring, and reporting of any errors through its status LED’s, optional display or communication port. Electronic error protections prevent damage when installation mistakes or system faults occur. Protected from overload, short-circuit, high voltage warning, reverse polarity, high temperature, and nighttime reverse current on the PV input side, and overload, short-circuit, high temperature, and reverse polarity on the load side. They are also protected from battery reverse polarity.
MODBUS communications protocol allows for easy programming, control, remote data access and charge synchronization. On-board data logging stores up to 256 days of detailed solar charge and load consumption data.
Load terminal connections provide Low-Voltage Disconnect and Reconnect, and can be programmed for lighting control (dusk to dawn or custom settings). Automatic PV Based Lighting Control is field adjustable with multi-event load control allowing many options for PV lighting systems. Models with the optional meter allow adjustments to charging, lighting, and load control settings without an external computer.
Wire terminals accept wire up to #6 AWG. The Remote Temperature Sensor allows for automatic adjustment of charge settings based on the battery temperature. The optional Meter display is a high resolution, LCD, multi-lingual, backlit graphical display.
Low noise design meets US Federal Communications Commission Class B specifications. ETL Listed: UL62109/CSA.107.1; IEC 62109; FCC Part-15 class B compliant.
These charge controllers are covered by a 5-year warranty.
