EXT - Ext Load current (the use of 10A up to 500A 75mV external current shunt is possible on both SBMS40 and SBMS120 see page 13 )
AD2 and AD3 - user available ADC inputs the value is the digital output of the ADC.
ht1, ht2 - reserved for power output of the DMPPT450
ERR - this is error code it will contain the information referring to the error flags on the SBMS.
There are 15 Flags (see monitoring page3 on SBMS) not all flags represent an error some are representing normal operation and if you consider
this a 15bit binary number each bit representing one flag with “1” highlighted and “0” not highlighted and you start from the top left with OV flag
and continue to right and then down to the last flag DFET and consider the OV as the least significant bit and DFET most significant bit then you
get this binary number and convert to decimal that will be the value contained in this ERR Status and you can also see this number on the SBMS
LCD just under the battery SOC value and also displayed as Status: in the html page.
Uncompressed data and formatted in .csv as it was on SBMS4080 will look like this
Y ,M ,D ,H ,M ,S ,SOC,cel1 ,cel2 ,cel3 ,cel4 ,cel5 ,cel6 ,cel7 ,cel8 ,IT ,ET ,-Batt , PV1 , PV2 ,ExtLoad, ADC2, ADC3, ADC4, heat1 , heat2 , ERR

This is the javascript function for decompression (you will find this inside the SBMS webpage) function dcmp(p,s,d){xx=0; for (z=0;z<s;z++){xx =
xx + ((d.charCodeAt((p+s-1)-z)-35)*Math.pow(91,z));}return xx;}
Were
p - location of the data in the string.
s - size of the data (example year is 1 cell voltage is 2 and PV1 current is 3)
d - the name of the variable in this case sbms.
