EARNMee MPPT Solar Boost Controller 1200W 30A — 12–60V PV to 48/60/72V, HD Display & High Efficiency

The EARNMee 1200W MPPT Solar Boost Controller is a compact, high-efficiency power manager that converts 12–60V PV input into selectable 48V, 60V, or 72V battery charging outputs with a maximum 15A output current.

This MPPT (Maximum Power Point Tracking) boost controller is designed to squeeze more usable energy from solar panels while giving you the flexibility to charge multiple high-voltage battery banks. It pairs sophisticated tracking algorithms with a clear HD color display and simple two-button controls so you can monitor performance, adjust settings, and protect your batteries without complex setup. Lightweight and rugged, it suits small off-grid systems, RVs, golf carts, and compact home arrays.

How does the MPPT boost controller increase solar harvest?

The controller continually finds the PV array’s optimum operating point so panels deliver near-maximum power under changing conditions. Conversion and tracking efficiencies are high, minimizing losses between your panels and batteries.

• Advanced MPPT algorithm for rapid power-point adjustments
• Tracking efficiency up to 99% and conversion efficiency near 98%
• Improves output under cloud cover, temperature shifts, and partial shading

Which battery types and voltages can it manage?

This unit supports a wide range of common battery chemistries and offers manual selection for multiple output voltages to match your bank. That flexibility makes it compatible with both legacy lead-acid systems and modern lithium designs.

• Compatible with Lead-acid, AGM, Gel, LiFePO4, and ternary lithium cells
• Manual output selection: 48V, 60V, or 72V battery banks
• Input PV voltage range: 12–60V with up to 30A input current

What monitoring and controls are available?

An HD color LCD presents key metrics—voltage, current, and power—in real time so you can verify system behavior at a glance. Two simple buttons let you navigate menus and change settings without digging through complex menus.

• High-definition color display for instant system readouts
• Two-button user interface for quick configuration
• Live display of PV input, battery voltage, charging current, and power

Is the controller durable and safe for long-term use?

Yes—its compact build and robust connectors support reliable field installation. Multiple protective systems and thermal management help prevent damage and extend component life.

• Upgraded MC4-compatible solar connectors for weather resistance
• Built-in intelligent cooling fan and thermal safeguards
• Protections for overcharge, over-voltage, over-current, over-power, and over-temperature

Who is this for? If you need a small, efficient boost-conversion controller that adapts to several battery chemistries and higher-voltage banks, the EARNMee 1200W MPPT model is a strong fit. It serves owners of compact off-grid systems, RVs and vans, golf cart retrofits, hobbyist arrays, and homeowners wanting to use lower-voltage PV modules with 48–72V battery systems. Installers and DIYers will appreciate the light weight, clear readout, and simple controls when space or budget limits rule out larger charge-management solutions.
