Everything has been working great except now will not charge. I ran some ac appliances to run down the battery and DSSR20 does not turn on. Solar panels are putting out about 33 volts. I also started van and DC-DC charge also and no charging note on SBMS0. Checked setting of EXTIO 3,4,5,6 all correct. Thermistor set at 1040 and 3000.

The SBMS0 shows both the charging and discharging are enabled.

Check that EXT IO4 is not disconnected (open circuit) maybe at the connectors either at SBMS0 or at the DSSR20.

EXTIO4 + has come loose. I checked the wire's conductivity, and there is none. It has a resistor 0.5W 10K Ohm in line. It's very hot here, so I need to check tomorrow morning. As always thanks for you help!

Glad to hear that problem was solved.
