1.4 Introduction to Maximu m Po wer Point Tracking Technolog y

Maximum Power Point Tracking (MPPT) is an advanced charging technology that enables the solar panel to output more power by adjusting the electric module's operating status. Due to the nonlinearity of solar arrays, there exists a maximum energy output point (maximum power on their curves. Unable to continuously lock onto this point to charge battery, conventional controllers (employing switching and PWM charging technologies) can't get most of the power from the solar panel. But a charge controller featuring MPPT technology can continuously track array capacity at maximum power point so as to get the maximum amount of power to charge the battery.

Take a 12V system as an example. As the solar panel's peak voltage is approximately 17V while the battery's voltage is around 12V, when charging with a conventional charge controller, the solar panel's voltage will stay at around 12V, failing to deliver the maximum power. However, MPPT controller can overcome the problem by adjusting the solar panel input voltage and current in real time, realizing a maximum input power

Compared with conventional PWM controllers, the MPPT controller can make the most of the solar panel's max. power and therefore provide larger charging current. Generally speaking, the latter can raise the er utilization ratio by 15% to 20% in contrast with the former.

Fig. 1-2 Solar panel output characteristic curve

Meanwhile, due to changing ambient temperature and illumination conditions, the max. power point varies frequently, and our MPPT controller can adjust parameter settings according to the environmental conditions in real time, so as to always keep the system close to the operating point. The whole process is entirely automatic without the no for human intervention.

1.5 Charging Stage Introd ucti ons

As one of the charging stages, MPPT cannot be used alone. It is required to combine boost charge, floating charge, equalizing charge a other charging methods to complete the battery charging process. A complete charging process includes: Quick charge, holding charge and floating charge. Charging curve is shown below:

Fig. 1-5 SLD Battery charging stages diagram
Fig. 1-6 LI Battery charging stages diagram

a) Fast charging

At the fast charging stage, as the battery voltage has not reached the value of full voltage (i.e. equalizing/ boost voltage) yet, the controller perform MPPT charging on the battery with the maximum solar power. When the battery voltage reaches the preset value, constant voltage charging will begin.

b) Sustaining charging

When the battery voltage reaches the set value of holding voltage, the controller will perform constant voltage charging. This process will no longer include MPPT charging, and the charging current will gradually decrease with time. Holding charge comes in two stages, i.e. equalizing charge and boost charge. The two stages are conducted without repe in which equalizing charge is started once every 30 days.

Boost charging

By default, boost charging generally lasts for 2h, but users can adjust preset values of duration and boost voltage point according to the ac needs. When the duration reaches the set value, the system will ther switch to floating charging.

Equalizing charging

Warning: Risk of explosion!

In equalizing charging, an open lead-acid battery can produce explosive gas, therefore the battery chamber shall have good ventilation condition

Note: risk of equipment damage!

Equalizing charging may raise the battery voltage to a level that may damage to sensitive DC loads. Check and make sure that allowable voltages of all the loads in the system are greater than the set valu battery equalizing charging.

Note: risk of equipment damage!

Overcharge or too much gas generated may damage battery plates and cause active material on the battery plates to scale off. Equalizing ch to an excessively high level or for too long a period may cause dar Read carefully the actual requirements of the battery deployed in the system.

Some types of batteries benefit from regular equalizing charging which stir the electrolyte, balance the battery voltage and finish the electrochemical reaction. Equalizing charging raises the battery voltage a higher level than the standard supply voltage and gasifies the batte electrolyte. If the controller then automatically steers the battery into equalizing charging, the charging duration is 120 mins (default). In order avoid too much generated gas or battery overheating, equalizing charge and boosting charging won't repeat in one complete charging cycle.

Note:

1) When due to the installation environment or working loads, the system can't continuously stabilize the battery voltage to a constant level, the controller will initiate a timing process, and 3 hours after the battery

reaches the set value, the system will automatically switch to equalizing charging.

2) If no calibration has been done to the controller clock, the control perform equalizing charging regularly according to its internal clock.

➤ Floating charging

When finishing the sustaining charging stage, the controller will switch floating charging in which the controller lowers the battery voltage by diminishing the charging current and keeps the battery voltage at the value of floating charging voltage. In the floating charging process, visible light charging is carried out for the battery to maintain it full state. A stage, the loads can access almost all the solar power. If the loads consume more power than the solar panel can provide, the controller not be able to keep the battery voltage at the floating charging stage, the battery voltage drops to the set value for returning to boost charge, the system will exit floating charging and reenter into fast charging.
