Product Description:

Solar Charge Controller LED 5A-20A    

This is a highly intelligent charge controller with Maximum Power Point Tracking (MPPT). The optimal and intelligent “MPPT + SOC” charge control is implemented. The power switching components consist of low-loss MOSFET type transistors that have a long operating life and guarantee high performance. The extremely low own consumption makes it especially suitable for solar home systems, solar street lamp system, advertising lighting, traffic management system, and other professional applications etc. With the reverse polarity protection, lightning protection, electronic fuse and automatic detection of faulty battery, the controller is robust, maintenance-free and user-friendly.

   

● Solar home system
● Public security monitoring system
● Solar street lamp system
● DC signal light power supply system
● Small and medium size telecommunication station power supply system
● Small size solar power station system and solar DC power supply system

·         Q. What is an UPS and What it is for ?

An uninterruptible power supply (UPS) is a device that allows your computer or telephone switch or critical equipement to keep running for at least a short time or longer time when the primary power source is lost. It also provides protection from power surges, spikes, brownouts, interference and other unwanted problems on the supported equipment.

·         Q. How long the UPS to run when power goes?

This can take 3 paths.
1.You can pick a UPS that is rated for pretty much the full VA you need so it will be running at 100% of capability and will thus last 'n' minutes.
2.You can pick a UPS that is rated at a much higher VA value than you really need so, for example, is running at 50% of capability and will thus last for longer than the UPS from option 1.
3You can use extra external battery packs to run for longer. If charging capability allows, the more and the bigger batteries you take with, the longer time UPS runs. 
or using a generator after about 6 hours, it will be more cost-effective, with a short runtime UPS to bridge the generator start-up gap.

Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
Grid-connected inverter does not need energy storage, but the energy can not be controlled, how much light to send online to the number of online, simply do not want people to the grid does not like.
Q:Three-phase photovoltaic inverter grid, the use of phase-locked loop is what?
Grid-connected inverter can be operated locally through the LCD screen, or through remote monitoring with dedicated monitoring software.
Q:PV grid-connected inverter can directly load it?
Grid-connected inverter is usually equipped with island protection function, can only receive the power grid, if the load directly, the output is disconnected.
Q:PV grid-connected inverter and independent inverter in the control of what is the difference
Photovoltaic grid-connected inverter is the assembly of the DC into AC power for the use of load, or do not use the load, the inverter after the AC power to the city power grid, when the electricity outage, the inverter will automatically
Q:Photovoltaic grid-connected inverter problem
But Baidu Encyclopedia clearly pointed out: the zero line is the secondary side of the transformer leads the neutral point of the line, and the phase line constitutes a circuit for power supply equipment.
Q:After the PV inverter, how to achieve the same period before the network?
It can automatically detect the generator and the grid frequency and voltage, in the frequency, voltage, phase are in line with the requirements of the grid to set the time before the release of the closing signal, so that it can be safely and securely connected.
Q:What is the difference between a PV inverter and a solar inverter?
The main component of the inverter is the three-phase bridge converter. The main purpose of the grid-connected inverter is to change the power to DC and change the AC power. The main purpose is to improve the power quality (because the wind power generation is very large
Q:Is the PV inverter a current source or a voltage source?
Photovoltaic inverter, also known as power regulator, according to the inverter in the use of photovoltaic power generation system can be divided into two kinds of independent power supply and grid.
Q:Grid-connected inverter is generally divided into photovoltaic power generation grid-connected inverter, wind power grid-connected inverter, power equipment and grid-connected inverter and other power generation equipment power generation inverter.
Grid-connected inverter is generally used with large-scale photovoltaic power plant system, a lot of parallel PV string is connected to the same set of inverter DC input, the general power of the use of three-phase IGBT power module, power
Q:Is the grid side of the grid and the inverter?
Off-grid system power transmission sequence: photovoltaic panels> relays> inverters> relays> electricity load;
