PowMr MPPT Solar Charge Controller

The PowMr MPPT solar charge controller is a 100% MPPT (Maximum Power Point Tracking) solar charger controller that can work with 12V, 24V, 36V, and 48V systems. It has a three-stage charging mode that includes constant current (MPPT), constant voltage (Absorption Voltage), and floating charge. This controller automatically recognizes the system type and works with sealed lead acid, vented gel, and lithium batteries.

Shenzhen Hehejin Industrial Co., Ltd. manufactures PowMr solar charge controllers. PowMr also has a solar installation project that covers topics such as lowering electricity bills and converting an inverter to a UPS.

The PowMr MPPT solar charge controller has the following features:

• Charging efficiency: Max efficiency of ≥98.1%
• PV utilization: PV utilization of ≥99%
• Electronic protections: Protects against short-circuiting, reverse-current, overcharging, overload, over-discharging, and reverse polarity.
• LCD screen: Allows for easy adjustment of charging mode parameters.
• Plug-and-play design: Saves time during installation and prevents errors caused by reverse connection.

MPPT solar charge controllers can detect the voltage and current of solar panels in real-time and adjust the output voltage to deliver the maximum available power from the photovoltaic array to the load. However, MPPT charge controllers are more expensive than PWM charge controllers, which are generally less than 80% efficient.

What is an MPPT solar charge controller?

An MPPT solar charge controller, or Maximum Power Point Tracking controller, is a DC-to-DC converter that optimizes the match between a solar array and a battery bank or utility grid. It does this by converting the higher voltage DC output from solar panels to the lower voltage needed to charge batteries.

MPPT controllers work by:

• Checking the output of the PV module
• Comparing it to the battery voltage
• Determining the best power that the PV module can produce.

MPPT charge controller can be used in a variety of conditions, including Cold weather, Cloudy or hazy days, when a battery is deeply discharged, Battery system voltage equal to or less than 48 V, and Battery system voltage greater than 48 Volt.

MPPT controllers are considered the most efficient device for controlling the charge flowing into a battery. They help avoid losing energy that the system captures and generates, maximizing what can be stored and used.

MPPT controllers have a voltage range of 24V to 250V, but some high-voltage models can operate up to 600V.

Here are some tips for installing a PowMr solar charge controller:

• Mount the controller indoors and away from water and direct sunlight.
• Ensure power connections are tight to prevent overheating.
• Install external fuses or breakers.
• Connect the battery first so the controller can recognize the system voltage.
• Don’t close circuit breakers during installation.

How to set PowMr MPPT charge controller?

Here are some steps for installing a PowMr solar charge controller:

• Mark the wall for the controller’s mounting holes
• Mount the controller.
• Connect the battery first to the controller.
• Connect the DC loads to the controller.
• Connect the solar panels to the controller.
• Connect the solar inverter to the controller.
• Check before starting up.
• Turn on and set up the controller.

Here are some tips for connecting multiple charge controllers in parallel:

• Connect each PV array individually to each controller.
• Connect every controller to the DC load.
• Set a parallel operation code for each controller.
• The controller with the lowest communication code value will be the master.
• If the master controller has an issue, the system will automatically switch to the next controller with the highest code value.

PowMr MPPT charge controller settings

Set parameters on a PowMr MPPT charge controller, you can:

• Press and hold the Speed button.
• Adjust the value with the Battery and DC buttons.
• Confirm with Set

To enter load mode settings, you can:

• Press and hold the DC button.

The PowMr MPPT charge controller has over discharge protection, which will cut off the DC output when it detects over discharge and restart it when the battery voltage recovers. The load mode settings include:

• 24h: Always on mode where the DC output remains open.
• Zero Edge: Load control mode where the DC output is enabled.

Here are some other tips for MPPT solar charge controllers:

• The absorption voltage should be 14.6 volts, with an acceptable range of 14.4 to 14.6 volts.
• The absorption time for lithium batteries is recommended to be half an hour per 100ah of LiFePO4 battery.
• The voltage output should be at least 5 V higher than the battery voltage for the MPPT to start and remain above 1 V for the charge to continue.
• The voltage value should be set according to the battery type.
• The length and quality of the cables between the solar panel and the MPPT are important for an efficient charge.

Is PowMr a good brand?

YES, I HIGHLY recommend this unit to others. YES, POWMR has proven themselves to me, as makers of good products, and EXTREMELY GOOD CUSTOMER SUPPORT! Thanks, PowMr folks, for a great product that has helped me to upgrade my system, where I could never have afforded to with the other prices.

Is a PowMr charge controller good?

Reviews for PowMr charge controllers are generally positive, with some customers saying they are good products with good customer support. The 60A MPPT Solar Charge Controller has a 98.1% efficiency rating and uses three charging stages to power a battery with a 60A current. It also has multiple electronic protections, including reverse polarity, short-circuiting, and overcharging. However, one YouTube review says that the 60A model should be treated like a 40A model, and that operating it under 120 VOC can help it last longer. Another review says that the PowMr responds quickly to changes in cloud cover and when it’s turned on and off, while a Victron takes 15–20 seconds to ramp up to MPPT.

Some say that PowMr charge controllers are reasonably priced, but not perfect. Others say that the 60A model can get hot after a full day of use.

PowMr MPPT Charge Controller User Review

100% would buy again. PowMr 60 Amp Review. A True MPPT solar charger is rated max at 48v battery (Lithium self-defined voltages) at 2,800w Max Solar Array & 150 Voc. Manual is ok English.

One Amazon reviewer is very happy with the PowMr MPPT Solar Charge Controller 60 and highly recommends it to others. They say that PowMr has good products and excellent customer support. However, the reviewer also notes that the wire holes are small for larger gauge wires and that the controller overheated and shut off due to its safety feature.

MPPT controllers can provide more power. Especially in colder temperatures, this system works well with less expensive 60-cell modules. However, consider the lower cost of a PWM controller when deciding whether an MPPT controller is the best choice for your system.
