The Lithium Solar Charge Controller is a type of charge controller specially optimised for charging Lithium-ion and LifePo4 batteries.
For a long time, solar charge controllers only supported charging lead-acid batteries, but as lithium-ion batteries have become more widely used in off-grid solar systems, an increasing number of controllers now support charging lithium-ion batteries.
Difference between a Lithium Solar Charge Controller and a Conventional Charge Controller
The main difference between a lithium solar charge controller and a lead-acid charge controller is the power management system. lithium solar chargers use constant current charging mode and must have a built-in protection board.
Like other dedicated solar controllers, lithium battery solar controllers have MPPT type and PWM type. An MPPT solar charge controller is a charge controller that uses a Maximum Power Point Tracking algorithm to harvest the most energy from the solar array.
PWM charge controller usually has only 70% conversion capacity compared to an MPPT mode. MPPT mode is strongly recommended in most cases, but some PWM charge controllers also stand out in practice.
We have selected the most popular LifePo4 battery solar charge controllers on the market for comparison and evaluation.
