10. Zyyini


Zyyini MPPT Solar Panel Controller,Solar Charge Controller Battery Charger for 12V Lead Acid Battery Packs

Zyyini #ad - Power saving: in the floating state, if the battery voltage drops to 83. 95% of the set overcharge voltage, a new charge cycle is automatically started. When the input power is lost or the input voltage is lower than the battery voltage, it automatically enters a low-power sleep mode. Multifunctional: high-end technology mppt solar maximum power tracking charging management chip, with trickle, over charging and floating charging mode, constant current, it is ideal for charging for 12V lead-acid batteries.

In the overcharge phase, and when the charging current is reduced to 38% of the constant current charging current, the charging current is gradually reduced, the floating state is entered. Solar cell maximum power point tracking: in constant current charging mode, the charging current is set by an external resistor. When powered by solar panels, the internal circuitry automatically tracks the maximum power point of the solar panel, allowing the user to maximize the output power of the solar panel.

Automatic switching mode: if the battery voltage is lower than 75% of the set overcharge voltage, the battery is trickle charged with 17. 5% of the set constant current charging current. Hight quality: pwm buck mode 12v lead-acid battery charge management integrated circuit, has the advantages of small package shape, which automatically manages the charge of lead-acid battery independently, few peripheral components and simple use.
