12V / 24V 20A MPPT太阳能充电控制器
描述：
MPPT的全名是最大功率点跟踪。它是一种先进的充电方式，可以检测太阳能电池板的实时功率和I-V曲线的最大点，从而实现最高的电池充电效率。
特征：
1，采用双峰或多峰追迹技术，用于太阳能电池板部分阴影或太阳能电池板部件损坏时的状态。
2，内置最大功率点跟踪算法，可以提高pv系统的能源利用效率。充电效率比PWM模式高出15％〜20％。
3，可以在1分钟内找出IV曲线的最佳工作点。 MPPT效率可达99.9％。
4，采用先进的数字电源技术，使能源转换效率达到97％。
5，四个充电阶段：MPPT - 均衡充电 - 增压充电 - 浮充电。
6，带限流充电模式。当太阳能电池板的功率过大时，控制器将自动降低充电电力，使系统在额定充电电流下工作。
7，有故障代码指示，有助于用户确认系统故障。
8，各种负载控制方式。可以自动识别白天和黑夜。
9，各种系统保护功能。包括过充电，过放电，过载，过热，电池反向连接和短路保护等。

使用建议
1.太阳能电池板的端子电压可能超过人体安全电压，请使用绝缘工具，确保手干。
请谨慎正确地连接电线。虽然控制器具有反向保护和短路保护，但这并不意味着它可以处理各种错误，反向连接和短路。
3.请勿将太阳能电池板连接到控制器的电池端口或负载端口，否则太阳能电池板的高压将损坏控制器。
4.请先连接电池，然后在控制器上的电池指示灯正常打开后连接其他设备。如果反向连接电池，负载端口的电压将为电池电压的负值。这可能会损坏负载设备。
5.MPPT控制器根据太阳能电池板的I-V曲线设计，因此当控制器连接一般恒压直流电源时，控制器可能无法工作。
6.安装在通风良好的环境中，因为控制器在运行过程中会发热。
7.选择适当的电缆，以避免电路中的额外功率损耗。电路损耗过多可能导致判断错误。
8.充电对电池来说非常重要。电池应至少每月充满电一次，否则电池将遭受永久性损坏。只有当电池的输入功率大于负载的功耗时，电池才能充满电。
9.请勿将控制器浸入腐蚀性液体中，否则会损坏控制器并释放有害气体。
由于电池存储大量的能量，所以不要在任何情况下允许电池短路。我们建议串联电池上的保险丝
11.电池可能释放可燃气体，请远离火花。
12.确保孩子远离电池，电池和控制器

12V/24V 20A MPPT Solar Charge Controller
Description:
The full name of the MPPT is maximum power point tracking. It is an advanced charging way which could detect the realtime power of the solar panel and the maximum point of the I-V curve that make the highest battery charging efficiency.
Feature:
1,Adopting double crest or multi crest tracing technique, used for the condition when a part of solar panel is under shadow or parts of solar panel is damage.
2,Builtin maximum power point tracking algorithm which could promote the energy utilization efficiency of pv system. The charging efficiency is 15%~20% higher than PWM mode.
3,It can find out the best working point of IV curve within 1 minute. the MPPT efficiency could reach to 99.9%.
4,Adopting advanced digital power supply techniques which makes the energy conversion efficiency reach up to 97%.
5,Four charging stages: MPPT - equalizing charge- boosting charge- floating charge.
6,With current limiting charging mode. When the power of solar panel is oversized, the controller will lower charging power automatically, which enable the system to work under the rated charging current.
7,Have the fault code indication, it helps user confirm the system fault.
8,Various load control methods. Could recognize day and night automatically.
9,Various system protection functions. Including over-charge, over-discharge, over-load, over-heat, battery-reverse connection and short-circuit protection etc.
Specifications:
Using Suggestion
1.The solar panel's terminal voltage may exceed human safety voltage, please use insulating tools and ensure the hands dry.
2.Please connect wires cautiously and correctly. Although controller has reverse protection and short circuit protection, that doesn't mean it could handle all kinds of wrong, reverse connection and short circuit.
3.Please don't connect the solar panel to the controller's battery port or load port, otherwise the high voltage of the solar panel will damage the controller.
4.Please connect the battery first, then connect other equipments after the battery indicator on the controller is normally on. If connect battery reversely, the voltage of the load port will be the minus value of the battery voltage. That may damage the load equipment.
5.MPPT controller is designed according to solar panel's I-V curve, so when the controller connect the general constant voltage DC source, the controller may not work.
6.Advice is installing in the ventilated and well-cooled environment, because the controller will fever during operation.
7.Choosing the proper cable with enough capacity to avoid extra power loss in the circuit. Too much circuit loss may lead to wrong judgment.
8.Full charge is very important for the battery. The battery should be full charged at least once a month otherwise the battery will suffer permanent damage. The battery can be full charged only when the input power of the battery is more than power consumption of the load.
9.Please do not dip the controller into the corrosive liquid otherwise the controller will be damaged and release harmful gas.
10.Because the battery stores lots of energy, do not allow the battery short circuit in any case. We suggest tandem connect a fuse on the battery
11.The battery may release combustible gas, please far away from the spark.
12.Ensure the children are far away from battery ,pv and controller
