i recently encountered a problem with the system i have had for a number of years, when the batteries are charged up the Multiplus units then dump the battery capacity back into the grid , then the multiplus units will grid charge the batts and then dump them back into the grid again , it cycles like this day and night. The system consists of 2x 5kva multiplus units connected parallel, 1x 5 kw + 1x 4kw SMA inverters, color controller. running ESS with feed into grid enabled.
