ECO-WORTHY L03PWM30A2.1BW-1
ECO-WORTHY PWM Solar Charge Controller 30A 12/24V with Bluetooth,WiFi | APP Remote Connection, Solar Panel Custom Battery Regulator, Dual USB Port Auto,for FLD/LiFePO4/SLD/GEL RV Solar System
In Stock
Budget 30 A PWM controller for 12/24V systems with an LCD, two 5V/2A USB ports and 30 days of built-in generation records. It offers LiFePO4, flooded, sealed, gel and custom charging profiles, and its 50 V maximum PV input is among the lowest listed, suiting small 12V panel setups in vans and boats. The listing says Bluetooth is built in, but also that Bluetooth and Wi-Fi need the separate BW0F data unit.

Features
- Smart Auto Voltage Detection: Auto-detects 12V/24V systems & features dual USB ports (5V/2A) for fast device charging. Track 30-day solar power generation via built-in data recording to optimize solar panel efficiency
- Remote monitoring:When paired with the BW0F Data Acquisition Unit, it enables Bluetooth and Wi-Fi connectivity. Bluetooth offers control from up to 98 feet in an open area for on-site operation, while Wi-Fi allows for remote monitoring via the app from any location after you leave.
- Universal Battery Compatibility: Compatible with all 12V/24V batteries. Choose preset modes (LFP, FLD, SLD, GEL) or customize parameters (CUS mode) for tailored charging
- Accurate monitoring: Built-in Bluetooth connectivity for easy operation. Advanced components ensure voltage/current measurement accuracy <1%. A clear LCD display shows real-time data; intuitive three-button control allows seamless adjustment of settings.
- 3-Stage PWM Charging: Intelligent bulk/absorption/float charging boosts efficiency & battery lifespan. Built-in safeguards against reverse, short circuit, overcurrent, low/high voltage and overheating
- Widely Used: Sturdy metal backplate for effective heat dissipation and protection of internal components; Ideal for RV camping, boating, and more outdoor applications
