With an ultra wide operating voltage range for photovoltaic arrays. MPPT maximum power point tracking technology of solar charging controller, the tracking efficiency is not less than 99.5%. Compared with the common PWM algorithm, the efficiency is improved by 15~20%. Using high quality imported components, advanced power conversion circuit, the maximum conversion efficiency can reach more than 98%. Photovoltaic charging has three-stage charging mode: MPPT- boost charging-floating charging. With overcharge, overdischarge, overtemperature, overload and other comprehensive protection functions. RS485 communication, can provide communication protocol, facilitate customer unified integrated management and secondary development. Inverter and bypass can achieve seamless switching, can achieve the switching process of electrical equipment continuous electricity. Inverter adopts built-in pure copper power frequency isolation transformer, instant load capacity is strong, load impact resistance is strong.

JN-MPPT-MINI-AL-BL-CL is a new product series of JN-MPPT solar charge controller. Since the first product was launched in August 2019, the cumulative sales of all products have exceeded 50,000 units until now. Of course, the rapid increase in sales is naturally inseparable from perfect product quality monitoring and the development of new performance. The JN-MPPT-MINI-AL-BL-CL product sequence will further strengthen the APP's remote communication function and the user's operating experience in 2020, and will meet the user's multiple needs to the greatest extent. Figure 1. For product layout, JNGE POWER is expected to launch high-power high-voltage solar controller products one after another in 2020 to improve the demand for solar controllers in solar high-voltage systems. At the same time, it will launch a new series of low frequency power inverters and a complete set of solar power system design solutions as one-stop service. In addition, our MPPT wind and solar hybrid controller has also been further improved. At present, the new hybrid controller has APP communication function, and has been put into production in small quantities. Users can monitor the overall parameters of the power generation system from the mobile phone, and can use the mobile phone The interface manually adjusts battery parameters, etc. At present, there are very few such products in the market with this APP function. Figure 2. In terms of production management and quality control, the JNGE team will continue to learn and summarize, strengthen the skills training of workshop personnel, strengthen the sense of service of employees, strengthen the quality inspection of inspectors, and reduce the rate of defective products (within 1%). Finally, in this special period of 2020, the JNGE team will continue to work together to overcome difficulties and usher in a new dawn.

From 28th Aug.to 20th Aug., JNGE Power Limited attended the San Polo Intersolar Exhibition.During this exhibition, JNGE Power show the JN-H inverter off grid solar inverter with newest technology, which attract a lot clients. Besides, our hot sale model JN-MPPT series MPPT solar charge controller as well as JN-K Series PWM solar controller are very interesting to our clients. We’d like to share some photos for your reference:

The PV module is a power generation device that is exposed to direct currentin the sun.It consists of almost all solid state photovoltaic cells made of semiconductor materials (such as silicon). Simple photovoltaic cells can provide energy for watches and computers, and more complex photovoltaic systems can provide lighting and traffic lights and monitoring systems for houses, and integrate them into power grid. Photovoltaic panel components can be made into different shapes, and the components can be connected to produce more electrical energy. Photovoltaic panels can be used on rooftops and building surfaces, and even used as part of windows, skylights or shelter devices. These photovoltaic facilities are usually referred to as photovoltaic systems attached to buildings.

The main control part of the solar street light is the controller, belonging to the "central nervous system" of the solar street light, controlling the charging and discharging of the solar street light, the battery overshoot protection, and the protection of the solar street light system as a whole. So how to choose solar street light controller? 1.choose the right current The current of the solar street lamp is 5A, 10A, 15A, 20A, etc. The current of the selected controller must be correct, and the selected current should be larger than the maximum current needed. For example, if the system current is 2A or 3A, we can choose 5A current. The maximum current is 5A, we can not only choose 5A current, the best choice 10A, to prevent the current is too large and burn the controller. 2.select the correct buck and boost features If the controller has step-down or step-up function, we have to choose the right one, and set the solar street light manufacturers before leaving the factory. 3.choose the right voltage Solar street lamp system voltage is 12 volts or 24 volts, but also a small part of the 36 volts and 48 volts, solar street light controller selection, we must choose the right voltage, or can not work. 4.electricity complementary controller and scenery complementary controller Electricity complementary controller and wind solar controller need to choose correct the electricity complementary voltage and fan voltage. 5.sub-time adjustment of the power controller, the choice of matching constant current source If you want street lighting to achieve sub-time control of brightness, you must select the matching of the constant current source, or impossible, different street controller on the constant current control requirements are not the same, so we must choose the right model .
