RP300 Solar Charge Controller for Lead Acid, SLA/AGM, and Lithium Batteries
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.

Replacement for malfunctioning controller supplied with battery box.
Customer service was excellent, going the extra mile to track down a partial address. Replacement controller was easy to install.

Works well for my test solar power rig
I'm just learning about setting up a solar power system on a small scale - learning by watching videos, reading books and doing what I can with what I can afford. Would love to just buy a full-out set-up system but those are expensive! So...I have a couple of 12V 200W solar panels and I have 3 different pairs (wired in series) LiFePO4 batteries (one pair is 12V, 8Ah wired in series to be 16Ah, another pair is 12V, 16Ah or 32Ah, and the last is 12V, 32Ah or 64Ah) plus a 2000W inverter and a 3000W inverter. This charge controller is set up between my solar panel and battery set to ensure a full charge and so I know when the batteries can be removed from the solar panel and another set added. I am working with these smaller sets as emergency power for when my house goes dark. I had a five day period last year without power and was not prepared. With this solar charge controller on my smaller solar set up, I'm feeling good about facing the next time the grid goes down (along with other preparations I've made).
