Charge Controllers - MPPT Controller

PowMr - 60A MPPT Solar Charge Controller

The PowMr 60A MPPT Solar Charge Controller is designed to optimize the energy harvesting from solar panels by employing advanced Maximum Power Point Tracking (MPPT) technology. With a tracking efficiency of up to 99.9% and a peak conversion efficiency reaching 98%, this controller effectively reduces power consumption and heat generation. It is equipped with a digital signal processor (DSP) for auto-detection of solar battery voltages ranging from 12V to 48V and supports various types of deep-cycle batteries such as Lithium, LiFePO4, Li(NiCoMn)O2, Flooded, Sealed, Gel, and user-defined batteries. Additionally, the controller features multiple electronic protections, including safeguards against PV short circuits, reverse polarity, battery overvoltage, overdischarge, load overcurrent, load short circuits, and over-temperature conditions. Its adaptive boost charging phase tailors the charging duration to battery response, enhancing battery longevity. The controller is also designed to support parallel operation for scaling solar energy storage systems up to 12 units, making it highly versatile for expanding solar setups.

PowMr - 10A MPPT Solar Charge Controller for Multiple Voltage Systems

The 10A MPPT Solar Charge Controller by PowMr is engineered for scenarios where the photovoltaic input voltage is lower than the battery voltage. It effectively boosts the input voltage to meet the battery charging requirements, overcoming the limitations of insufficient voltage from a single photovoltaic panel. The controller boasts up to 99% tracking efficiency and 98% peak conversion efficiency, enabling optimal battery charging from solar panels. It utilizes a multi-stage charge algorithm, including bulk charge, boost charge, and float charge phases, with customizable charging voltages via an LCD screen. Suitable for various battery types, such as LiFePO4, Gel, and flooded lead-acid, it supports multiple system voltages (24V/36V/48V/60V/72V). The adaptive boost charge feature intelligently assesses the battery’s response during initial charging and adjusts the boost charge duration to ensure full recharging without accelerating battery aging.
