Could you provide a list of your settings in your MPP LVX-6048? It would be good to also have a single line diagram so we can consider modifications to better balance your system's Voltages.
I am ionizing the water by spraying it (atomizing as in a carburator) onto the high voltage ignition system of an ICE car (the separate molecules are better split when floating in the air, instead of in the "compressed" liquid state). The two emf poles will easily pull the molecule apart (same...
The basics of energy flow are: it moves from the higher potential to the lower potential (Voltage). If you do not want that to happen (i.e. from an alternator into a solar panel) you must use an isolator bus (two in - two out) or a diode switching device. There are many other options depending...
A simple way of providing battery storage without a complex design is by installing a stand alone modular system, which you can add to if found necessary. Here is one for 48V: https://www.evwest.com/catalog/product_info.php?products_id=487
Otherwise you may end up causing a fire without knowing...
If you placed 8 cells in series per module, supervised by a dedicated BMS and paralleled with the other 3 supervised modules, you would not have to create this monitoring system. The individual faulty module would shut down and the other 3 modules would continue to supply the loads. Easier said...
