Applied a update to my batteries this morning. They are now doing something very interesting and likely to save me and others with two or many more a lot of input power.

Battery 2 is just starting maintenance cycle and is almost fully charged. It seems to be waiting for my second battery to start charging. Battery1 is just completing maintenance and is at 0%.

Previously Battery 2 would have been sending 2ish kW to my building use or overflow to the grid.

More than happy not to export power add it back to Battery1. Noting the Extractor modification from years back may also see DC Discharge to DC recharge which eliminated the small loss of inverter conversion from or to AC/DC power.

Well done RFX. My tiny scale $$ benefit would be $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ at larger sites.
