Hello everyone, before I get into my questions, let me give a little insight or background of what I do. I work for a company that provides water treatment options for a large variety of industrial water treatment options. We build temporary water treatment systems where ever needed by our customer's request, usually construction sites for dewatering, and stormwater runoff, and a few permanent systems at large recycling plants. Our systems are all automated, they can run unmanned and we have remote capabilities to operate/monitor from a mobile device or a computer.

We have solar panels, a charge controller, and 2 deep-cell marine batteries (24V) to power our PLC, which is the brain of our system. Batteries are lead acid, old, and not working very well for what we need. We have an EcoFlo River 2 Pro that seems like it might be our savior. The PLC doesn't draw much power, less than 2A. What I need to find out if it's possible, is there a way to get the SOC from the EcoFlo unit to our PLC to monitor its state of charge? Our treatment systems run on a generator at 480V 100A, during idle time when nothing is running, the PLC monitors the system, and when needed it calls the generators for power and the system runs, saving roughly $3000 a month in fuel costs. What we are looking to do is, read the SOC when it gets low, the PLC can call for the generator to turn on, provide power and recharge it.

Basically, is there a way to read the SOC from inside the River 2 Pro and wired to our PLC to get the reading?
 
Probably not, unless you find a way to integrate the EcoFlow App somehow with a custom piece of software to monitor its percentage.

You could theoretically set up a timer circuit that would run the generator for an hour every X number of days or something like that.
