What are the settings for a 12V solar controller? ›

Basic Settings of Solar Charge Controllers

The range for a 12V system is usually 10.8V to 11.4V, for a 24V system it's 21.6V to 22.8V, and for a 48V system, it's 43.2V to 45.6V. Typically, the values are 11.1V, 22.2V, and 44.4V. Battery Overcharging Protection Voltage – Set this according to your battery type.

Victron's MPPT charge controller size is denoted by two numbers with a / between them. The first number represents the panel voltage that can be applied and the second number is the amperage it can pass through. For example one of the most popular charge controllers is the 100/50 unit.

Recommended charger settings for SolarKing Lithium Batteries 100AH and above. Bulk Charge We recommend 14.6v maximum. Float Charge We recommend 13.6v but this can be set to a maximum of 14.0V. Charge Current We recommend 30Amp.

The voltage value should be set according to the battery type. The voltage value range is between 14.1V to 14.5V for 12V system, 28.2V to 29V for 24V system and 56.4V to 58V for 48V system.

Sizing the correct solar controller for your set up is critical. Too small and you risk losing the power your panels are creating, too large and you are wasting money on something you do not need.

You take the total watts of the solar array divided by the voltage of the battery bank. That will give you the output current of the charge controller. For example, a 1000W solar array ÷ 24V battery bank = 41.6A. The rating of the charge controller should be at least 40A.

A lithium battery can be charged as fast as 1C, whereas a lead acid battery should be kept below 0.3C. This means a 10AH lithium battery can typically be charged at 10A while a 10AH lead acid battery can be charged at 3A. The charge cut-off current is 5% of the capacity, so the cutoff for both batteries would be 0.5A.

For a 4S LiFePO₄ battery, we recommend a multi-stage charge profile with a charge voltage of 14.4V (3.6VPC), 30 mins Absorption time in order to balance the lithium cells, and then dropping to a float voltage of 13.6V.

What is the best charge level for LiFePO4 battery? ›

What Is the Optimum Voltage for LiFePO4? The optimum voltage for a LiFePO4 (Lithium Iron Phosphate) battery typically ranges between 13.2V and 13.6V for most applications.

Lithium Ion batteries are charged with an absorption voltage of 14.25 V for 12 V, and 28.5 V for 24 V systems. The float voltage is 13.5 V for 12 V and 27 V for 24 V systems.

Lithium-ion battery packs should not be totally depleted and recharged frequently ("deep-cycling"). Utilising only 20 or 30 percent of the battery's capacity prior to recharging will greatly improve your battery life. Five to ten shallow discharge cycles are roughly equivalent to 1 full discharge cycle.

Manage the Discharge

Unlike other types of batteries that need to be recharged throughout their storage time, lithium batteries do better at 40%-50% DOD (depth of discharge).

At Sunstore we are often asked about how the solar charge controller load output terminal should be used. The load output on the charge controllers is ideal for putting small lighting circuits on in sheds, garages and outbuildings.

Battery Type Description: B1 is an acid battery (automatic identification 12V 24V); B2 is a lithium-ion battery (11.1V lithium battery series 3); B3 is lithium iron phosphate battery (4 sets of 12.8V), factory default setting is B1.
