PowMr 30A PWM Solar Charge Controller — Auto 12-48V, LCD Display, Dual USB Output

Smart, adaptable charging for 12–48V solar systems

PowMr’s updated 30A PWM solar charge controller is built to adapt across commonly used voltages, from 12V up to 48V. It accepts PV inputs up to 100V and supports a wide range of power levels, making it suitable for compact cabins, RVs, boats, or off‑grid sheds. The integrated LCD offers a clear, real-time view of charging activity, while dual USB ports provide convenient power for small devices without needing an extra adapter.

With its robust yet compact design, this controller is designed to sit quietly in your system, quietly watching over your energy flow while you go about daily tasks or adventures. The user interface is straightforward, so you can quickly check status, adjust settings, or confirm that charging is underway as conditions change throughout the day.

Three-stage PWM charging for safe, efficient power

The controller uses a three‑stage charging approach (Bulk, Boost, Float) to optimize charging cycles. This helps manage energy flow efficiently and supports steady, reliable charging across varying weather and load conditions.

Battery compatibility and simple wiring

Designed to work with 12V, 24V, 36V, and 48V battery banks, it is adaptable to multiple chemistries such as Flooded, AGM, GEL, LifePO4, and Lithium packs. For installation, follow the recommended wiring order: connect the battery first, then the solar panel, and finally the load to help ensure a smooth start.

• Compatible with a variety of battery types and system voltages for flexible installations
• LCD screen provides real-time data for easy monitoring and parameter adjustment
• Built-in 2 USB ports offer 5V and 2A outputs for peripheral devices

Protection and reliability you can rely on

Equipped with overcharge protection, overload protection, short circuit protection, and reverse current protection to help safeguard your photovoltaic setup and prolong battery life.

• Overcharge and short circuit protections reduce risk in varying sun conditions
• Reverse current protection helps prevent battery drain when panels aren’t producing power

Real‑world uses and benefits

Ideal for off‑grid cabins, marine applications, RV adventures, and remote workshops, this controller provides a dependable balance of power management and user-friendly control. Expect clearer visibility of charging status, better battery health over time, and the flexibility to power a range of devices directly from the system.

While outcomes can vary with conditions, the PowMr controller offers possibilities for smoother energy management, faster setup, and a more informed view of your solar charging process.
