PowMr MPPT Solar Charger Controller 25A/35A/45A

MPPT Solar Charger Controller technology gives you stronger, more consistent solar charging performance. This controller helps your system capture more usable energy every single day.

MPPT Solar Charger Controller – Benefits for You

✅ Optimizes power harvesting so you get more usable energy from your solar panels.

✅ Improves battery longevity by adjusting charging behavior to match your battery type.

✅ Reduces wasted power through precise tracking, helping your off‑grid system stay efficient even in changing light.

✅ Minimizes system downtime by maintaining stable performance across wide temperature and humidity ranges.

✅ Enhances system safety so you avoid damage from overcharging or unstable input conditions.

Take control of your off‑grid power setup with a controller designed to make every watt count.

This MPPT Solar Charger Controller refines how your 12V or 24V system captures energy, adjusting intelligently to flooded, sealed, gel, and lithium batteries. Its three‑stage charging ensures that every battery type receives the right balance of bulk charging, absorption, and float maintenance. That means fewer worries about overcharging and more confidence that your power bank stays healthy.

The controller’s positive‑ground structure and forced‑air cooling keep internal temperatures steady even during demanding conditions. With low self‑consumption—44mA at 12V and 26mA at 24V—it preserves stored energy when sunlight isn’t available. Its IP32 housing and reliable operation from -35°C to +45°C make it suitable for remote cabins, RVs, small off‑grid homes, and portable solar systems.

Its electrical capabilities support a wide range of solar setups. Power limits scale across 25A, 35A, and 45A models, allowing you to pair the controller with the panel array that fits your needs. The MPPT tracking efficiency exceeds 99%, while conversion efficiency reaches up to 98%, giving you strong overall system performance. With a battery voltage operating window from 9V to 30V and built‑in temperature compensation, it adapts well to real‑world conditions.

Compact sizing across the three models makes installation straightforward whether mounted in an RV compartment or a wall‑mounted off‑grid station. Lightweight construction helps keep your system streamlined while still delivering the robust functionality you expect.

Its clear interface gives you a quick at‑a‑glance understanding of charging status and system behavior.

The rear layout keeps wiring manageable and accessible during installation.

Clear connection points help reduce setup errors and ensure a stable system configuration.

The onboard screen provides real‑time voltage, current, and charging stage information to keep you informed.

Upgrade your solar system with a controller built for efficiency, reliability, and long‑term off‑grid performance.
