Good morning, very new to solar so please keep any answer simple to understand, I have a pair of US300C batteries and I'm trying to find out accurate detail on the max rate of charge that they should be set to to ensure maximum life. My invertor is a Solis and watching some setup videos it suggests that on one of the invertor screens that the batteries will show the max rate? I have checked this and got one figure (was far lower than the example in the video), however, I then go further into the setup and note that the invertor is looking to charge at a higher rate (this was set by the installers) so I have currently left everything the way it was installed, but would not like to think that I'm harming the batteries, whilst also thinking that both figures appear to be on the low side? (not added any figures so as to keep the discussion open)
