Feature of the PWM solar charger controller

INTELLIGENT DISPLAY: The solar controller comes with a LCD display that can clearly indicate the status and data, such as digital display, current, voltage, load identification, battery identification, charging identification, etc. it can be conveniently switched modes and parameter configurations.

MULTI-PROTECTION: Over-current and short-circuit protection, inverse connection protection, low voltage and overcharge protection. PCB circuit board, Waterproof:IP32

20A/12V & 24V: handles up to 30A of array current, keeps 12 or 24 volt batteries properly charged, PWM charging model. Best choice for green energy.

NOTE: Charge controller can only use the photovoltaic panel as a charging source. Do not use a DC or other power source as a charging source. Only suit for lead-acid batteries! The charge controller should connect the battery first, then the solar panel, and finally the load! The disassembly sequence is contrary to the wiring order. The charge controller will heat up when it is running. Please be careful to install the charger controller on a flat, well-ventilated place.

The circuit board inside the controller adopts high-quality conformal coating to protect the circuit board from environmental erosion. After curing, it forms a transparent protective film, which has excellent insulation, moisture-proof, anti-leakage, shock-proof, dust-proof, anti-corrosion, anti-aging, corona resistance and other properties.
