Overview
The PowMr Pstar Series PWM solar charge controller is designed for off-grid solar systems, with automatic 12V/24V/36V/48V system voltage identification, an LCD display, dual USB output, and silent (fanless) operation. It uses PWM charging technology with a 3-stage charging algorithm to optimize charging and discharging and help extend battery service life.
Key Features
- PWM charging with 3-stage charge algorithm
- Auto system voltage: 12V/24V/36V/48V
- LCD display and function keys for operation
- Dual USB output: 5V/2A*2
- Multiple protections: reverse connection, over-temperature, overvoltage, short-circuit, overload
- Lithium battery activation (feature shown on product materials)
- Battery compatibility: LiFePO4, SLA (sealed lead-acid), GEL, FLD (flooded), AGM
- Silent operation via natural convection cooling (fanless design)

Protection & Operation Notes
- To ensure lithium battery safety, do not charge lithium batteries when their temperature is below 0°C.
- Read the user manual carefully before installation and connect solar panels, battery, and loads correctly.
- Over-temperature behavior: charging stops when internal temperature exceeds 85°C and resumes when it drops to 75°C or below.
Applications
- Off-grid solar systems
- Home solar lighting
- Garden power supply
- Outdoor monitoring power supply

Details
Built for off-grid solar setups, the Pstar series controller combines PWM charging with an easy-to-read LCD and dual 5V USB outputs.
Multiple built-in protections help reduce wiring mistakes and electrical faults, and lithium battery activation support is included.
Works with common battery types including LiFePO4 and lead-acid (AGM/GEL/FLD/SLA), with automatic 12V–48V system detection.
Simple front-panel controls and USB charging ports pair with a die-cast aluminum body for durable, fanless cooling.
Clearly labeled PV, battery, and load terminals make installation easier when wiring panels, batteries, and DC loads.
Choose the charging current that fits your system—30A, 60A, or 80A—within the same Pstar PWM controller family.
