Compact PWM Solar Charge Controller with Temperature Probe and LCD Display This intelligent 20A regulator manages solar panel charging for 12V and 24V systems using pulse width modulation charging. The built in temperature probe and LCD display allow more accurate battery charging and easy monitoring of system status. Designed for small off grid installations, vehicles, boats, and other standalone solar applications where reliable battery management is required. Key benefits Reliable battery management: PWM charging reduces overcharge and improves battery life by controlling charge current to matched voltage levels. Temperature compensation: Integrated temperature probe adjusts charging parameters as battery temperature changes, helping maintain charge under varying conditions. Clear system information: LCD display provides visible status of battery voltage, charging current, system mode, and simple configuration without extra tools. Simple compatibility: Auto detect or selectable 12V and 24V operation fits common small solar setups without complex wiring changes. Compact and easy to install: Space saving design and straightforward terminal connections make installation quick for DIY and professional installs. What it does Regulates charging from solar panels to battery using PWM technique to limit overcharge. Monitors battery voltage and charging current and displays system status on an integrated LCD. Uses a temperature probe to adjust charge parameters for temperature dependent battery compensation. Provides a single 20 amp rated output suitable for small battery banks and modest solar arrays. Key features and attributes Function: PWM solar charge regulation with temperature compensation and status display. Compatibility: Designed for 12V and 24V battery systems and standard solar panel input ranges for small systems. Rating: 20A maximum controller output capacity for charge management. Display: Built in LCD for clear readout of voltage, current, charging state, and basic settings. Controls: Intelligent regulator logic for automated charging cycles and easy configuration. Design: Compact footprint and robust enclosure suited to indoor or protected outdoor installations. Accessories: Includes temperature probe for accurate compensation. Performance notes Improved charging consistency compared to basic controllers because PWM reduces voltage spikes and provides smoother charging profiles. Temperature compensation helps prevent under or overcharging when ambient or battery temperature deviates from nominal conditions. Rated for continuous operation at up to 20 amps; actual performance depends on ambient temperature and installation conditions. Typical applications RV and camper systems: Manage a 12V or 24V house battery charged by a roof mounted solar panel array and monitor charge status while parked or traveling. Off grid cabin or small cottage: Control charging for battery banks in small standalone power systems powering lights, pumps, and electronics. Marine and leisure craft: Maintain battery health on boats by regulating solar charging and compensating for temperature changes while at sea or docked. What to expect in use Straightforward wiring to solar panel, battery, and load terminals. LCD provides immediate feedback for commissioning and troubleshooting. Temperature probe placement near the battery allows charging settings to adjust automatically with changing battery temperature. This PWM solar controller provides practical, easy to use charge regulation for small 12V and 24V solar systems where consistent charging, temperature compensation, and simple monitoring are important.
