ISEMS CSV file format and hex error codes

The ISEMS CSV communication and storage data output revision 1 uses the following format:

Data fields

01 Node-ID = nodeid ;
02 ISEMS-Paket-Format-Revision = packetrev ;
03 Epoch-Timestamp = timestamp ;
04 FREIFUNK-OPEN-MPPT-Firmware-Version and controller type = firmware_type ;
05 Time-until-next-scheduled-power-shutdown (in minutes) = nextreboot ;

07 Solarmodule Open-Circuit-Voltage V_oc, Value Volt DC = V_oc;
08 Solar-MPP-Voltage V_in, Value Volt DC = V_in ;
09 Battery voltage V_out, Value Volt DC = V_out;
10 Battery Charge State estimate (in percent) charge_state_int;
11 Battery Health estimate (in percent) health_estimate;
12 Battery temperature in Celsius = battery_temperature; 
13 Low Voltage Disconnect Voltage, Value Volt DC = low_voltage_disconnect;
14 Temperature corrected charge end Voltage, Value Volt DC = temp_corr_V_end ;
15 Rated Battery_Capacity in Amperehours Ah = rated_batt_capacity;
