Introduction

The REGO series is the culmination of RENOGY's ten years of industry experience by modeling "Lego" energy building blocks for power solutions. The REGO 12V 60A MPPT Solar Charge Controller has achieved several firsts as a key member of the entire REGO Collection. Focusing on rapid plug and play and safety, the REGO 60A MPPT reduces installation time and integrates a high BPU (Battery Protect Unit) technology achieving the highest protection against battery cells damage and battery failure, especially Lithium. The compact and robust nature of the controller not only has a sense of technology and fashion, but also saves on installation space relative to the competition. The REGO 12V 60A MPPT Solar Charge Controller is easily one of the most reliable controllers on the market yet.

Key Features

• 【Rapid Plug & Play】 The quick plug port design reduces installation to a simple "click" when connecting your battery bank and solar panels. Uncomplicated programming issues by simply turning the battery selector knob to your battery type and quickly provide accurate charging services for different battery types.
• 【Smart Chat, Perfect sync】 Let software do all the work by using the embedded Bluetooth technology or daisy chaining devices for software communication. Software will adjust the charging current based on smart chat experience between energy devices. The entire REGO system will actively respond to the needs of the battery, and provide more accurate charging services.
• 【MPPT: Ultra Fast Maximum Power Point Tracking】 Built-in maximum power tracking algorithm with advanced dual-wave or multi-wave tracking technology can significantly improve the utilization efficiency of solar power generation by about 15%-20% higher than the traditional PWM charging efficiency. The ultra-fast technology can still accurately trace the maximum power point to obtain the maximum power generation efficiency if panels are shaded with a charge conversion efficiency greater than 95%.
• 【Smart Battery Manager】 REGO 12V 60A MPPT Solar Charge Controller adopts a three-four-stage charging design for Lead Acid Batteries and two-stage charging for Lithium batteries: 1 - high-current boost (bulk), 2 - constant voltage charging (boost), 3 - floating stage (float), 4 - equalization stage (EQU), corresponding to the different power situations of the battery. When the battery level is very low, the controller will provide high-current charging at this time that allows the battery to recover quickly. The REGO 12V 60A MPPT Solar Charge Controller offers a range of functions for different battery types, from charging to maintenance, and is a smart battery manager.
• 【Protection】 Full high-temperature protection at the solar input and battery output terminals. Input terminal protection also includes solar reverse polarity, solar overvoltage, solar short circuit, solar night back-flow protection. Output terminal protection also includes battery overcharge, battery overdischarge, and battery reverse polarity. The REGO 60A 12V MPPT Solar Charge Controller BPU protection embeds protection into the controller rather than separate protection components safeguarding your system.
• 【Quality Assurance】 REGO 12V 60A MPPT Solar Charge Controller features a 5-year warranty and is multi-certified to UL1741, CAN/CSA-C22.2 No. 107.1/CB+IEC 62109/EMC, EN61000-3-1/-3; EN301489-1/17; RF, EN300328; and FCC, 47 CFR 15B.

MPPT技术

In many cases, the MPPT charge controller will "boost" up the current in the solar system. The current does not come out of thin air. Instead, the power generated in the solar panels is the same power that is transmitted into the battery bank. Power is the product of Voltage (V) x Amperage (A). Therefore, assuming 100% efficiency:

Power In = Power Out

Volts In * Amps In = Volts out * Amps out

Although MPPT controllers are not 100% efficient, they are very close at about 92-95% efficient. Therefore, when the user has a solar system whose Vmp is greater than the battery bank voltage, then that potential difference is proportional to the current boost. The voltage generated at the solar module needs to be stepped down to a rate that could charge the battery in a stable fashion by which the amperage is boosted accordingly to the drop. It is entirely possible to have a solar module generate 8 amps going into the charge controller and likewise have the charge controller send 10 amps to the battery bank. This is the essence of the MPPT charge controllers and their advantage over traditional charge controllers. In traditional charge controllers, that stepped down voltage amount is wasted because the controller algorithm can only dissipate it as heat. The following demonstrates a graphical point regarding the output of MPPT technology.

Current vs. Voltage(12V System)

Output Power(12V System)

Limiting Effectiveness

Temperature is a huge enemy of solar modules. As the environmental temperature increases, the operating voltage (Vmp) is reduced and limits the power generation of the solar module. Despite the effectiveness of MPPT technology, the charging algorithm will possibly not have much to work with and therefore there is an inevitable decrease in performance. In this scenario, it would be preferred to have modules with higher nominal voltage, so that despite the drop in performance of the panel, the battery is still receiving a current boost because of the proportional drop in module voltage.

Four Charging Stages

REGO 12V 60A MPPT Solar Charge Controller has a 4-stage battery charging algorithm for a rapid, efficient, and safe battery charging. They include: Bulk Charge, Boost Charge, Float Charge, and Equalization.

Battery Voltage

CHARGING CURRENT

Bulk Charge: This algorithm is used for day to day charging. It uses 100% of available solar power to recharge the battery and is equivalent to constant current. In this stage the battery voltage has not yet reached constant voltage (Equalize or Boost), the controller operates in constant current mode, delivering its maximum current to the batteries (MPPT Charging).

Constant Charging: When the battery reaches the constant voltage set point, the controller will start to operate in constant charging mode, where it is no longer MPPT charging. The current will drop gradually. This has two stages, equalize and boost and they are not carried out constantly in a full charge process to avoid too much gas precipitation or overheating of the battery.

Boost Charge: Boost stage maintains a charge for 2 hours by default. The user can adjust the constant time and preset value of boost per their demand.

Float Charge: After the constant voltage stage, the controller will reduce the battery voltage to a float voltage set point. Once the battery is fully charged, there will be no more chemical reactions and all the charge current would turn into heat or gas. Because of this, the charge controller will reduce the voltage charge to smaller quantity, while lightly charging the battery. The purpose for this is to offset the power consumption while maintaining a full battery storage capacity. In the event that a load drawn from the battery exceeds the charge current, the controller will no longer be able to maintain the battery to a Float set point and the controller will end the float charge stage and refer back to bulk charging.

Equalization: Equalization is carried out every 28 days of the month. It is intentional overcharging of the battery for a controlled period of time. Certain types of batteries benefit from periodic equalizing charge, which can stir the electrolyte, balance battery voltage and complete chemical reaction. Equalizing charge increases the battery voltage, higher than the standard complement voltage, which gasifies the battery electrolyte.

• ! CAUTION: Equalization is carried out only for non-sealed / vented/ flooded / wet cell lead acid batteries.
• DO NOT equalize VRLA type AGM / Gel / Lithium cell batteries UNLESS permitted by battery manufacturer.
• ! WARNING: Once equalization is active in the battery charging, it will not exit this stage unless there is adequate charging current from the solar panel. There should be NO load on the batteries when in equalization charging stage.
• Over-charging and excessive gas precipitation may damage the battery plates and activate material shedding on them. Too high of an equalizing charge or too long of one may cause damage. Please carefully review the specific requirements of the battery used in the system.
• Equalization may increase battery voltage to a level damaging to sensitive DC loads. Ensure that all load allowable input voltages are greater than the equalizing charging set point voltage.
