Overview

 

Thank you for selecting 12v 24v 48v auto MPPT solar charge controller. Our MPPT is essentially a smart DC to DC converter which has been optimized to harvest maximum energy from the PV array in battery based solar electric systems by using a variety of maximum power point tracking (MPPT) strategies. The controller’s secondary objective is to ensure that the batteries receive a full charge without becoming overcharged. This is accomplished through a four stage charging process.

Advantage Overview:

Traditional controllers connect the solar module directly to the battery when recharging. This requires that the solar module operate in a voltage range that is usually below the module’s Vmp. In a 12 Volt system for example, the battery voltage may range from 10 - 15 Vdc, but the module’s Vmp is typically around 16 or 17 Volts. Figure 5-1 shows typical current vs. voltage and power output curves for a nominal 12 Volt off-grid module.

 Nominal 12 Volt Solar Module I-V curve and output power graph

 

 

 

The array Vmp is the voltage where the product of output current and voltage (Amps x Volts) is greatest, which falls on the “knee” of the solar module I-V curve as shown on the left in Figure 5-1.

 

Because traditional controllers do not always operate at the Vmp of the solar array, energy is wasted that could otherwise be used to charge the battery and power system loads. The greater the difference between battery voltage and the Vmp of the module, the more energy is wasted. MPPT technology will always operate at the maximum power point resulting in less wasted energy compared to traditional controllers.

 

Conditions That Limit the Effectiveness of MPPT

The Vmp of a solar module decreases as the temperature of the module increases. In very hot weather, the Vmp may be close or even less than battery voltage. In this situation, there will be very little or no MPPT gain compared to traditional controllers. However, systems with modules of higher nominal voltage than the battery bank will always have an array Vmp greater than battery

voltage. Additionally, the savings in wiring due to reduced solar current make MPPT worthwhile even in hot climates.

Maximum solar module power

Multiple solar modules in parallel connection(Refer to Fig.4-8): The sum of their voltages must not Exceed open circuit voltage of 150V.The sum of the solar power must Not exceed the maximum capacity of the unit.(see above Table)

 

 

MPPT Technology

MPPT stands for "Maximum Power Point Tracking". This describes a process by means of which the solar module is always operated at the point of maximum possible power. Because the point the maximum power can vary depending on the operating mode and the local conditions, and because it changes in the course of the day, the term "tracking" is used, i.e. the tracking of this point.

 

Current Boost

Under most conditions, MPPT technology will “boost” the solar charge current. For example, a system may have 36 Amps of solar current flowing into the MPPT and 44 Amps of charge current flowing out to the battery.The MPPT does not create current! Rest assured that the power into the MPPT is the same as the power out of the MPPT. Since power is the product of voltage and current (Volts x Amps), the following is true*:

 

(1) Power Into the MPPT = Power Out of the MPPT

(2) Volts In x Amps In = Volts Out x Amps Out

* assuming 100% efficiency. Losses in wiring and conversion exist.

 

If the solar module’s maximum power voltage (Vmp) is greater than the battery voltage, it follows that the battery current must be proportionally greater than the solar input current so that input and output power are balanced. The greater the difference between the Vmp and battery voltage, the greater the current boost. Current boost can be substantial in systems where the solar array is of a higher nominal voltage than the battery.

 

Battery Charging Information

4-Stage Charging

The MPPT has a 4-stage battery charging algorithm for rapid, efficient, and safe battery charging. Figure 4-2 shows the sequence of the stages.

 

MPPT Charging Algorithm

 

Bulk Charge Stage

In Bulk charging stage, the battery is not at 100% state of charge and battery voltage has not yet charged to the Absorption voltage setpoint. The controller will deliver 100% of available solar power to recharge the battery.

Absorption Stage

When the battery has recharged to the Absorption voltage setpoint, constant-voltage regulation is used to maintain battery voltage at the Absorption setpoint. This prevents heating and excessive battery gassing. The battery is allowed to come to full state of charge at the Absorption voltage setpoint. The Absorption setpoint is temperature compensated if the RTS is connected.

Float Stage

After the battery is fully charged in the Absorption stage, the MPPT reduces the battery voltage to the Float voltage setpoint. When the battery is fully recharged, there can be no more chemical reactions and all the charging current is turned into heat and gassing. The float stage provides a very low rate of maintenance charging while reducing the heating and gassing of a fully charged battery. The purpose of float is to protect the battery from long-term overcharge.

 

The Float setpoint is temperature compensated if the RTS is connected.
