PowMr 80A MPPT Solar Charge Controller - 12/24/36/48V, 160V PV Input, Parallel up to 12, Lithium/AGM Support

This controller combines advanced MPPT tracking with multi-stage charging and comprehensive protections so you can harvest more energy from your panels while safeguarding batteries. It is engineered for flexibility — compatible with lead-acid, gel, AGM, flooded and lithium batteries — and built to scale, letting installers expand capacity by linking multiple units in parallel.

How does this controller increase energy harvest compared with simpler regulators?

The PowMr 80A uses Maximum Power Point Tracking (MPPT) algorithms to continuously adjust input to match panel output at peak power points, increasing charging efficiency. It achieves tracking efficiencies up to 99% and peak conversion efficiencies up to 97%, which typically yields more usable charge from the same PV array compared to PWM controllers.

• MPPT algorithm for real-time maximum power capture
• Up to 97% peak conversion efficiency
• Accepts high PV voltages (up to 160V) for larger panel strings
• Compatible across 12V/24V/36V/48V systems for design flexibility

What battery types and charging modes are supported?

The controller includes selectable battery types and a three-stage charge algorithm (Bulk, Boost, Float) to optimize battery health and charging cycles. A lithium-specific mode with activation function is available, and the user-defined setting allows fine tuning for uncommon battery chemistries.

• Pre-configured modes: Sealed, Gel, AGM, Flooded, Lithium
• Three-stage charging to prevent overcharging and extend battery life
• User-defined parameters for custom battery profiles
• Lithium activation feature to wake and protect lithium packs

Can this controller scale for larger systems and how do parallel connections work?

Yes — the updated model supports linking up to 12 controllers in parallel, enabling higher total current and expanded battery capacity without requiring a single oversized unit. Parallel operation simplifies system growth: add units as your energy needs or PV array increase.

• Supports up to 12 controllers in parallel for larger arrays
• Parallel mode increases total charge current and storage headroom
• Suitable when expanding PV input power and battery bank size
• Maintains individual protections while working as a coordinated system

What safety and protection features are included?

The PowMr controller integrates multiple hardware and software protections to protect panels, wiring, and batteries from common faults. These protections reduce risk of component failure and simplify maintenance.

• PV input over-current and short-circuit protection
• PV and battery reverse polarity safeguards
• Load short-circuit protection and over-temperature shutdown
• Comprehensive battery charging safeguards to prevent overcharge

Who this is for: installers, off-grid homeowners, RV and marine users, and small commercial systems that require a robust, scalable MPPT controller. It suits anyone planning an expandable solar setup who wants higher panel-voltage support (up to 160V), flexible battery compatibility, and the option to increase system capacity by paralleling units rather than repurchasing a larger single controller.
