My batteries are charged to 100% but as soon as this happens, the mppts turn off and the batteries start discharging, until about 96% then the mppts kick in again to recharge them. I have a mppt 250/85 and a 450/100, the smaller mppt has a load out option in the settings, I've set it to always on, thinking that solar would power loads instead to batteries once it reached 100% but that's not happening, that 250/85 mppt still turns off. The 450/100 doesn't have any load out options in the settings, why is that?
Is this behaviour normal? As in this case I would like to use just the mppt power to divert to hot water, but it seems the battery is doing this.
