The system i have “inherited” has two 150W solar panels, each driving a 75/15MPPT. These two MPPTs charge a single bank of 3 AGM batteries. it seems to me that the two MPPTs should be communicating with each other, but there is no comms between them. i have looked through the documentation but haven’t found the right information. is it ok for them to run independently? i would appreciate it if someone could point me to documentation on setting up multiple MPPTS such as this. Thanks
There’s no need for them to communicate, multiple controllers and other charge sources can be concurrently charging a single battery bank with no problems.
