Compatible with multiple battery types? The solar controller is compatible with 12V/24V/36V 48V/60V/72V/84V/96V lithium-ion and lead-acid batteries, including GEL, LiFePO4, Li-ion, user. Wide coverage of battery voltage, whether it is as low as 12V or as high as 96V battery type, can be perfectly adapted. Extremely versatile, it can realize multi-purpose use and fully meet the requirements of different stages and various scenarios. Advantages? Y&H MPPT controller is equipped with full power input function to provide stable and sufficient power for the equipment, which has obvious advantages in high-power and complex power demand scenarios. Multi-protection? Solar voltage regulator has overcharge protection, overcurrent protection, overheating protection, short circuit protection. Lithium battery activation can effectively activate lithium batteries that may be in a low-activity state and restore them to a good working condition, thus extending the service life of lithium batteries. Application Scenarios? : Off-grid solar power systems for homes and farms, off-grid solar power systems for small workshops and factories, RVs, boats and off-grid solar power systems. Y&H controller is used in solar off-grid power generation systems to automatically regulate battery charging and discharging. It has an advanced tracking algorithm to obtain the maximum power of the solar module to charge the battery; at the same time, its Low Voltage Disconnect (LVD) function prevents the battery from over-discharging and causing damage. The MPPT controller’s comprehensive self-test function and electronic protection function can avoid damage caused by installation errors and system failures. Maximum power point tracking technology, can significantly improve the energy utilization of solar energy system, conversion efficiency of up to 97%. Battery voltage available:12V/24V/36V 48V/60V/72V/84V/96V. Multiple battery type settings: Lead Acid, Gel, LifePo4, Li, User. PV Open Circuit Voltage: 0V-230V, Charging current (A) is adjustable. Automatic compensation of charging voltage and current according to battery temperature to prolong battery life. Wide range of high voltage: the same type of 60A controller can withstand up to 150V, while the 12V battery can withstand up to 45V, Y&H controller 12V battery system can withstand up to 230V, the advantage is obvious. PV minimum input is calculated as about 1.5-2 times the battery voltage. (Example: 12V battery, minimum input voltage is 18V-24V voc). 1:Lead-acid batteries: 60V/72V/84V need to be adjusted manually. 2:solar panel input voltage minimum input: to be greater than the maximum battery voltage of 20V; maximum does not exceed 230V. MPPT automatic maximum power tracking. MPPT tracks maximum power, fast charge balanced charge, and float charge. Single voltage 3.2number of strings (4 strings -45 strings adjustable)Saturation voltage 3.65V. Single voltage 3.7number of strings (2 strings -45 strings adjustable)Saturation voltage 4.2V. Adjustable limit voltage for equal charge, float charge and DC discharge:8V-170V. With lithium battery activation function. With photovoltaic input, there is charging voltage (activate lithium battery), can be used without battery DC output. PV maximum open circuit input voltage. The charging current is adjustable. PV voltage is greater than +3V of battery voltage (low current charging on rainy days). According to the temperature of the battery, the charging voltage and current are automatically compensated to prolong the battery life.
