FAQ

It is required to connect the battery first, if the battery polarity is reversed in this step, the controller has the protection and would not be damaged. But if the user connects the PV first and then, unfortunately, connects the battery polarity reversed, the controller would be damaged. This is caused by lithium battery characteristics.

Negative battery current means battery is discharging, this could happen when no PV or PV power is not enough to power the loads.

About MPPT Charge Controllers

Introduction on MPPT Charge Controllers?

  • The most basic functionality of a solar power system is solar panels collecting energy from the sun and storing it in batteries so that you can use it whenever you’d like.
  • However, you can’t simply connect your solar panels directly to your batteries and expect them to charge.
  • To get the most out of your solar panels, you’ll need a charge controller to charge your batteries efficiently.
  • The most efficient type of charge controller is the maximum power point tracking or MPPT charge controller like the EPEVER 10-40A MPPT Charge Controller.

What is Maximum Power Point Tracking?

Before we dive into how MPPT charge controllers (EPEVER 10-40A MPPT Charge Controller) work, let’s explain how they get their name.

  • The voltage at which a solar panel produces the most power is called the maximum power point voltage. The maximum power point voltage varies depending on environmental conditions and the time of day.
  • MPPT charge controllers  like the  EPEVER 10-40A MPPT Charge Controller get their name because they monitor the solar panel and determine the maximum power point voltage for the current conditions. This function is called maximum power point tracking, or MPPT for short.

What Is An MPPT Charge Controller? 

  1. Solar panels and batteries have different optimal operating voltages. Not only that, these voltages fluctuate. An MPPT charge controller (EPEVER 10-40A MPPT Charge Controller) is a DC-DC converter that maximizes the efficiency of a solar system. It does this by optimizing the voltage match between the solar panel array and the batteries.
  2. For example, depending on the state of charge, a 12-volt battery has a nominal voltage that ranges between just over 10 volts and just under 13 volts. Furthermore, the voltage required to charge a 12-volt battery ranges between 13.5 and 14.5 volts depending on the charging phase.
  3. On the other hand, the optimum output voltage of a solar panel varies depending on the panel’s temperature, time of day, how cloudy it is, and other environmental factors. For instance, under ideal conditions, a 250-watt solar panel may have an optimal operating voltage of 32 volts. As the panel heats up in the sun or on a hot day, the optimal voltage may drop to as low as 26 volts.
  4. The rated panel voltage must be higher than the battery voltage to accommodate for these voltage drops in the panel and the increased required battery charging voltage. Without an MPPT charge controller (EPEVER 10-40A MPPT Charge Controller), this voltage differential leads to a lot of wasted power.

Benefits of an MPPT Charge Controller

More Efficient at Using Power

On a properly sized solar power system, it’s not uncommon to see up to a 30% increase in efficiency by switching to an MPPT controller like the EPEVER 10-40A MPPT Charge Controller. This efficiency increase is even more significant on systems where the solar panel voltage is much higher than the battery voltage, like our example above.

Best for Large Systems

Utilizing an additional 20-30% of power out of your system becomes more advantageous as the size of your system grows. For this reason, MPPT controllers (EPEVER 10-40A MPPT Charge Controller) are often best used on large systems and may not be worth it on smaller, simpler setups.

Better in Cloudier Environments

The maximum power point tracking feature of MPPT controllers (EPEVER 10-40A MPPT Charge Controller) is a huge benefit in cloudy environments where the max power point of the solar panels will be fluctuating all day.

The difference between PWM and MPPT solar charge controllers

The crux of the difference is:

  • With a PWM controller, the current is drawn out of the panel at just above the battery voltage, whereas
  • With an MPPT solar charge controller the current is drawn out of the panel at the panel “maximum power voltage” (think of an MPPT controller (EPEVER 10-40A MPPT Charge Controller) as being a “smart DC-DC converter”)
You often see slogans such as “you will get 20% or more energy harvesting from an MPPT controller”.   This extra actually varies significantly and the following is a comparison assuming the panel is in full sun and the controller is in bulk charge mode.  Ignoring voltage drops and using a simple panel and simple math as an example:
     Panel maximum power current (Imp)  = 5.0A
     Panel maximum power voltage (Vmp)  = 18V
  1. Battery voltage = 13V (battery voltage can vary between say 10.8V fully discharged and 14.4V during absorption charge mode).  At 13V the panel amps will be slightly higher than the maximum power amps, say 5.2A
  2. With a PWM controller, the power drawn from the panel is 5.2A * 13V = 67.6 watts.  This amount of power will be drawn regardless of the temperature of the panel, provided that the panel voltage remains above the battery voltage.
  3. With an MPPT controller (EPEVER 10-40A MPPT Charge Controller) the power from the panel is 5.0A * 18V = 90 watts, i.e. 25% higher.
  4. However this is overly optimistic as the voltage drops as temperature increases; so assuming the panel temperature rises to say 30°C above the standard test conditions (STC) temperature of 25°C and the voltage drops by 4% for every 10°C, i.e. total of 12% then the power drawn by the MPPT will be 5A * 15.84V = 79.2W i.e. 17.2% more power than the PWM controller.

In summary, there is an increase in energy harvesting with the MPPT controllers (EPEVER 10-40A MPPT Charge Controller), but the percentage increase in harvesting varies significantly over the course of a day.
