EARNMee 1200W MPPT Solar Boost Controller 30A — 12–60V PV to 48/60/72V, 99% MPPT

The EARNMee 1200W MPPT Solar Boost Controller is a compact, high-efficiency charge regulator that converts 12–60V PV input to selectable 48V/60V/72V battery outputs while maximizing solar harvest with up to 99% MPPT tracking efficiency.

This MPPT boost controller is built for off-grid and mobile power systems where space, reliability and conversion efficiency matter. It accepts a wide range of PV and battery types, shows real-time operating data on an HD color LCD, and includes protections and cooling to keep the system stable under varied conditions. Designed to be easy to install and operate, it fits applications from RVs and small cabins to golf carts and auxiliary battery arrays.

How does the MPPT boost feature increase solar energy capture?

The controller constantly tracks the maximum power point of your solar panels, adjusting input parameters to extract the most available energy as sunlight and temperature change. That dynamic tracking raises energy harvest considerably compared with fixed-point or PWM controllers.

• MPPT tracking efficiency up to 99% to follow panel Vmp precisely
• Conversion efficiency around 98% to minimize losses during boost conversion
• Operates across 12–60V PV input to suit different panel arrays

Which batteries and voltages can I use with this controller?

The EARNMee controller supports common battery chemistries and lets you manually select the target bank voltage to match your system. It is compatible with lead-acid varieties as well as modern lithium types, giving flexibility for upgrades or mixed installations.

• Supported chemistries: Lead-acid, AGM, Gel, LiFePO4, and Ternary Lithium
• Selectable output banks: manual 48V, 60V, or 72V configurations
• Rated maximum output current of 15A for charging higher-voltage banks

What monitoring and protection features are included?

An HD color LCD shows voltage, current, and power so you can verify system performance at a glance. Built-in protections and an intelligent cooling fan protect components and batteries from common hazards without complex configuration.

• Real-time display of PV voltage/current and battery status on the LCD
• Protections: overcharge, over-voltage, over-current, over-power, and over-temperature
• Upgraded MC4 connectors for dustproof and waterproof PV connections and a cooling fan for thermal control

How simple is installation and daily operation?

Installation is compact and straightforward; the unit weighs only 0.7 kg and uses familiar MC4 PV connectors. Daily interaction requires only two buttons to change settings or view data, keeping setup and routine checks fast for non-technical users.

• Small footprint and lightweight design for easy mounting and placement
• Two-button interface for intuitive configuration and monitoring
• Works with single-crystal or polycrystalline PV panels up to 1200W input power

Who this is for: The EARNMee 1200W MPPT Solar Boost Controller is intended for DIY off-grid enthusiasts, RV owners, small-cabin installers, and anyone needing to charge higher-voltage battery banks from lower-voltage PV arrays. It works well when space and efficiency are priorities, when you need support for multiple battery chemistries, and when reliable protections and simple monitoring are desired. If you want a compact boost MPPT controller that transforms 12–60V PV arrays into stable 48/60/72V charging with clear system feedback, this model is a practical choice.
