Hi,
OK, my set up, 300W solar, epever 30a controller, 100Ah lithium, with JBD BMS.
I have set the BMS to shut off charge at about 90%, and discharge at 20%, and mirrored these settings in the solar controller.
The loads are connected directly to the battery NOT the epever 'load' terminal
The problem, the BMS keeps shutting off both the charge and discharge switches.
I have been trying to work out when this occurs as the logging is not perfect on the BMS.
I have narrowed it down to the situation where the sun is shining, battery is charged (no solar output), a load starts to take power, firstly from the battery, then as the Epever algorith kicks in from solar. when the load is switched off the solar keeps supplying the power until it sees the battery is full, then it stops, however before this transition happens in the epever, the BMS has cut boh charge and discharge FETs. could this be what the 'load' port on the epever is to prevent?
I hope this makes a bit of sense, If someone can suggest useful avenues for further investigation, I am all ears.
Thanks in advance
Ian
