Setting parameters for a lithium iron phosphate (LiFePO4) battery inverter/controller involves configuring several key aspects to ensure optimal performance and safety. Here are some typical parameters you might need to set:
Inverter/Controller Settings（12V）
Select "12V (14.6V) Ll (LiFePO4) Mode" or Select "User Mode" to enter values according to below parameters:
Note: These parameter settings are for a single 12V 100Ah lithium battery. If batteries are connected in series, the voltage values need to be multiplied by the number of batteries.
