POWLSOJX 20A/40A/60A MPPT Solar Controller 12V-48V Auto, 150V PV Input with DSP Chip & 6 Protections for Li/AGM/Gel LCD Display, USB Port, 97% Efficiency (20A)

Features

• 97% MPPT Conversion Efficiency：Harness 100% true MPPT technology with DSP chip precision, achieving up to 97% energy conversion even under low-light conditions. Continuously tracks solar panel voltage/current curves to maximize output for RVs, cabins, and telecom stations.
• 3-Stage Smart Charging & Protection Bulk-Absorption-Float Charging: Extends battery lifespan for lead-acid/GEL/lithium batteries Triple Safeguards: Overcharge cutoff, PV reverse polarity auto-shutdown, and thermal throttling (＞75℃/167℉) Current Limiting: Prevents overloads during high-demand device connections
• Auto-Voltage Detection (12V/24V/36V/48V)：Instantly recognizes battery bank voltage without manual switches. Seamless integration with solar arrays from 150W to 2000W, ideal for expanding hybrid energy systems.
• Plug & Play Customization One-Touch Battery Presets: Optimize charging for sealed/GEL/lithium via LCD menu Discharge Scheduling: Program load runtime for lights/pumps via intuitive buttons Error Diagnostics: LED indicators pinpoint issues (PV short circuit, low voltage)
• Industrial-Grade Durability：Aluminum alloy housing with IP32 waterproof rating withstands dust, humidity (-25℃ to +55℃), and voltage spikes. Emergency disconnect sequence (load→PV→battery) ensures safe maintenance.
