GR300 Solar Charge Controller for Lead Acid, and similar items

The GR300 is Gridless Revolution's new standard charge controller for all solar generators. When purchased separately it can be mounted flush in an RV, van, on a wall, or in your own unique application. Automatic battery recognition for 12/24V Flooded, AGM and GEL batteries. Lithium batteries can be manually set. Modern and Efficient 3-stage PWM charging: equalize, boost and float (for Flooded, AGM and GEL). 2-Stage user friendly settings for lithium batteries. Simple menus with a Large Back-lit LCD display. The display shows system status, solar input current, solar input voltage, battery voltage, and battery state of charge (%). The menu rotates through these parameters automatically, so a wireless camera can be used to remotely monitor them. Temperature compensation for better battery charging in cold or hot ambient temperatures. Features Automatic battery recognition for 12/24V Flooded, AGM and GEL batteries.
