Black plastic solar charge controller with LCD screen and two USB ports

Vszerda

Vszerda 30A 12V 24V Solar Charge Controller LCD USB gadget

SKU CH-D8N3-8FT3R

A 30 A PWM solar charge controller for 12 V or 24 V systems with LCD display, dual USB ports up to 2.5 A, and support for 32 battery types including lithium and lead-acid

  • 30 A charge current handles large solar arrays
  • LCD display shows real-time voltage and current
  • Dual USB ports deliver up to 2.5 A for devices
  • Supports 32 battery types including lithium and lead-acid
  • Built-in protections guard against short circuit and reverse polarity

Solar charge controller for multiple battery types

The Vszerda unit manages charging for 12 V and 24 V systems and supports 32 battery profiles including lead-acid, lithium-ion and lithium iron phosphate configurations. It is suited to off-grid setups where a single controller must handle different chemistries without manual reconfiguration.

PWM charging with dual USB outputs and protection

A built-in industrial microcontroller runs fully automatic three-stage PWM charge management and remembers settings after power loss. Dual USB ports deliver up to 2.5 A total for device charging, while short-circuit, open-circuit, reverse-polarity, overload and dual-MOSFET reverse-current protections keep the system safe with low heat production.

Voltage limits define usable panel

Maximum solar input is 23 V for a 12 V battery bank and 46 V for a 24 V bank, so panel strings must stay within those ceilings. Adjustable set-points cover float charge at 13.7 V, discharge cut-off at 10.7 V and recovery at 2.6 V, but the 30 A current ceiling caps total array power regardless of voltage headroom.

Questions about this item

Does the 30 A PWM controller limit panel voltage to 23 V for a 12 V battery and 46 V for a 24 V battery?

Yes, the maximum solar panel voltage is 23 V with a 12 V battery and 46 V with a 24 V battery, and the 30 A rating caps the charge current.

What mounting holes or brackets does the plastic case need for wall or DIN-rail installation?

The plastic enclosure has four corner mounting holes for screw fixing to a flat surface; no DIN-rail clip is included.

How do I set the lithium battery type on the LCD, and which step do users often skip?

Hold the single button to enter the battery menu, select the 3-string 11.1 V Li-ion or 4-string 12.5 V LiFePO4 profile, then confirm; many forget to confirm and the controller stays on the default lead-acid setting.
