POWERWIN MPPT50 50A Solar Charge Controller | 12V/24V MPPT for Off-Grid Systems

The POWERWIN MPPT50 50A Solar Charge Controller brings Maximum Power Point Tracking efficiency to mainstream off-grid builds — supporting 12V, 24V, 36V, and 48V battery systems with up to 100V solar input and a built-in USB output, priced at $60.00.

• MPPT Technology — Continuously tracks and locks onto the solar panel's peak power point, extracting up to 30% more energy than PWM controllers — critical in low-light and partial-shade conditions.
• 50A Continuous Output — Handles serious panel arrays for cabins, RVs, boats, and remote telecom setups — enough current to charge large battery banks quickly without throttling.
• Multi-Voltage Auto-Detect — Automatically identifies 12V, 24V, 36V, or 48V battery systems on connection — no manual configuration needed when swapping between builds.
• 100V Max Solar Input — Accepts higher-voltage panel strings, giving you flexibility to wire panels in series for longer cable runs with less voltage drop.
• Dual USB Output (5V/2.5A) — Powers phones, tablets, and small devices directly from the controller — no inverter needed for basic device charging at your off-grid site.
• Wide Operating Temperature — Rated from -35°C to 60°C, this controller performs in extreme cold and desert heat without thermal shutdown.
• LiFePO4 Compatible — Supports lithium iron phosphate battery chemistry alongside AGM, Gel, and flooded lead-acid — future-proofs your system as you upgrade batteries.
• 1-Year Warranty — Backed by manufacturer warranty with technical support, giving you confidence in long-term reliability for permanent installations.
