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.
