I know this has already been asked before - but wanted to see if anyone has a suggestion for my specific issue. I have a site that has 2 x MPPT 150-35. One has around 1300Watts of solar and the other around 1800Watts of solar. Both MPPT regulators then charge the same battery bank in parallel on their output. I also have a BMV700 to monitor the system. One of the solar panel banks probably gets sun a little earlier than the other. It seems like when sun hits the second bank the second solar regultor goes into absorption mode pretty much straight away - I assume becuase it thinks the battery bank is already well charge because the first regulator is already feeding. However I believe the batteries are not that well charged and the idea is to get both solar panel banks feeding the batteries in bulk when required. Anyone have any ideas? Is there a way of syncing or having the regulators talk to one another or act in parallel operation better?
