Temank PowMr MPPT 60A Solar Charge Controller — Parallel Version, 12/24/36/48V Auto, Programmable 2–60A

The Temank PowMr MPPT 60A is a programmable solar charge controller that auto-detects 12/24/36/48V systems, delivers up to 60A charging, and can be paralleled up to 12 units to expand system capacity.

Designed for medium-to-large off-grid arrays, RVs, marine installations and commercial setups, this MPPT controller maximizes solar harvest while giving installers flexible current limits and battery profiles. Built-in die-cast aluminum cooling, an upgraded turbofan and an external temperature probe help protect batteries and maintain performance under load. The controller supports multiple battery chemistries with user-adjustable charge parameters and extensive fault protection.

How does parallel operation increase system capacity?

Paralleling lets you multiply the available charging current by adding more identical controllers to the same battery bus. The PowMr 60A supports up to 12 units in parallel, so you can scale from a single 60A controller to a system capable of much higher aggregate current without redesigning the battery or PV array topology.

• Up to 12 controllers in parallel for larger arrays and redundancy
• Each unit programmable independently for staged charging and maintenance
• Simplifies system upgrades — add a controller instead of replacing one
• Improves reliability by distributing load and reducing single-point failure risk

What battery types and settings can I use with this controller?

The controller includes preset profiles for common batteries (sealed, gel, flooded, LiFePO4 and lithium-ion) and allows custom charge parameters for less-common chemistries. Users can set absorption/float voltages, low-voltage cutoffs and load timers, and adjust the charging current anywhere between 2A and 60A to match battery manufacturer recommendations.

• Preset profiles for lead-acid (sealed, gel, flooded) and lithium chemistries
• Programmable absorption, float and cutoff voltages plus load timer
• Charging current configurable from 2A to full 60A rated output
• External temperature probe for temperature-compensated charging

How does the device manage heat and protect battery life?

Thermal design combines a die-cast aluminum housing with an intelligent turbofan that activates above 45°C and turns off below 40°C, keeping noise and wear down. The controller offers comprehensive protections — overcurrent, short-circuit, reversed polarity, overvoltage, over-discharge and over-temperature — to reduce risk to the battery and system components.

• Die-cast aluminum body for passive heat dissipation
• Quiet turbofan cooling with automatic temperature thresholds
• External temp probe for more accurate battery temperature monitoring
• Multiple electronic protections to safeguard the system

What PV input and installation considerations should I follow?

PV input recommendations vary by system voltage: follow the suggested PV power and voltage ranges to avoid overvoltage and maintain MPPT performance. Always disconnect PV input before changing parameters; the unit provides a factory-reset option (battery only connected) by holding the last button for five seconds to clear settings or recover from night-mode display.

• 12V: recommended PV power up to 720W, PV voltage DC20–75V
• 24V: recommended PV power up to 1440W, PV voltage 37–100V
• 36V: recommended PV power up to 2100W, PV voltage 50–155V
• 48V: recommended PV power up to 2800W, PV voltage 72–155V

Who is this for: installers, fleet operators and DIY solar enthusiasts who need a flexible, high-efficiency MPPT controller for medium to large off-grid systems. It’s suited to RVs, boats, cabins, solar-powered commercial equipment and any installation where scalability, precise battery charging and robust protection are priorities. If you plan to grow your solar array or use lithium chemistry with temperature compensation, this controller provides the programmability and safety features required by modern systems.
