PowMr 60A MPPT Solar Charge Controller for 12–48V Batteries — Parallel Version, 160V PV Input & LCD

PowMr 60A MPPT Solar Charge Controller is a high-efficiency, multi-voltage solar regulator designed to manage up to 2800W of PV input and charge 12V–48V battery banks with intelligent MPPT tracking and LCD monitoring.

This compact controller uses a DSP-based MPPT algorithm to maximize solar harvest while giving you detailed system feedback on a backlit LCD. It supports 12V, 24V, 36V and 48V battery systems with automatic detection, accepts PV input up to 160V (or 150V when using the LCD), and supplies up to 60 amps of regulated charge current. Built-in protections, a quiet bladeless cooling fan, and a plug-and-play temperature sensor make it suitable for mobile and stationary off-grid applications.

How does this controller improve solar charging efficiency?

The MPPT (Maximum Power Point Tracking) software continually adjusts the operating point of the PV array to extract maximum power. With a DSP controller and a claimed efficiency at or above 98.1%, it raises PV utilization and improves charge currents across a wide range of sunlight conditions. Real-time energy recording lets you confirm performance over days or months.

• 100% MPPT design with DSP-based tracking for rapid adjustments
• PV input tolerance up to 160V (150V with LCD) and 2800W maximum
• Real-time display of PV voltage, charge current, battery voltage and power

Which battery chemistries and voltages are supported?

The controller auto-detects 12V, 24V, 36V and 48V battery banks and is configurable for multiple battery types. It has presets for sealed, flooded, gel, NiCd and several lithium chemistries (including LiFePO4 and Li(NiCoMn)O2). Note: lithium battery settings require manual configuration to match the battery's recommended charge/float voltages.

• Automatic detection for 12V/24V/36V/48V systems
• Preset profiles for lead-acid types and user-programmable lithium profiles
• Programmable absorption, float, low-voltage disconnect and load timer

What protections and system diagnostics are included?

The PowMr controller includes multiple safety features to protect PV arrays and batteries, plus a troubleshooting mode to help identify issues quickly. The LCD presents operating parameters and fault codes so you can adjust settings or isolate problems without additional tools. Two positive and two negative terminals for both PV and battery improve wiring flexibility and current distribution.

• Over-voltage, over-current and reverse-polarity protections
• Troubleshooting function and backlit LCD for quick diagnostics
• Dual connectors per positive and negative PV/battery terminal (9 AWG copper wiring compatible)

How does the cooling and temperature compensation work?

An upgraded bladeless fan provides quieter, more efficient thermal management, turning on above 45°C and off below 40°C to reduce audible noise while protecting electronics. A plug-and-play temperature sensor is included so the controller can apply temperature compensation during charging, improving battery life and performance across temperature ranges.

• Bladeless fan triggers at >45°C, stops below 40°C for low-noise cooling
• Included temperature sensor for automatic compensation of charge voltages
• Ideal for RVs, boats, commercial vehicles and fixed off-grid systems

Who this is for: installers and DIYers who need a versatile, high-current MPPT regulator for small to medium off-grid systems — including RVs, marine setups, caravans, remote cabins and commercial vehicles. It suits users who want detailed monitoring, flexible battery support, parallel expandability and quieter cooling, but who will manually set lithium parameters to match manufacturer recommendations.
