The displayed state of charge of the batteries (SOC) value is an indicative value based on a mathematical calculation. This SOC value gives an informative value with a precision tolerance. If you want to display a specific value of the SOC then, it will be necessary to invest in an additional meter. The inverter displays the state of charge of the batteries (SOC) according to the voltage. It is important to check the type of batteries used (AGM or GEL) before installing them. Make sure that the absorption voltage (Bulk) and the holding voltage (Float) are correctly set in the inverter using the IMEON OS. ONE software. The factory setting of the “absorption” voltage is 56 Vdc and the “Float” voltage is 54 Vdc. Please contact the battery manufacturer to validate the dimensioning of the battery park with IMEON.
