Use this tool to determine initial charging parameters for the SC-2030 Solar Charger. Adjust P1, P2, P14, P15, P21 after a few charge/discharge cycles to obtain stable performance.
When the TM2030 and SC2030 are connected together, there are 8 charging parameters you must enter in the TM-2030 to define a charging profile that is specific to your battery make/model. Select the battery make/model or type and enter information about the system, to obtain the eight values.
At any time after they are programmed into the TM-2030 you may individually modify any of these parameters.
Please note: P3 has a default value of 220 amp hours. You must enter the correct battery amp hour capacity for your system.
If your battery is not listed, start with the settings for a generic AGM/Gel or flooded cell type battery and then fine tune the parameters based on your usage patterns.
Parameter P8 is for setting the highest value the battery voltage can reach during charging. We have provided this feature as a means to avoid excessive voltages that any DC device like an inverter may experience. This parameter is unrelated to the charging process and must be set 0.5V higher than the highest value in a charging profile (usually P15).
For more information on each charging parameter, refer to the SC-2030 Technical Manual.
Important! Battery charging recommendations provided on the Bogart Engineering website, including the charge parameter calculator and SC-2030 instructions, as well as contained in Trimetric TM-2030 firmware and instructions, are based on data directly obtained from the battery manufacturer. Charging recommendations are subject to change without notice, and Bogart Engineering makes no guarantee of the accuracy of this information.
