Product Description:

Solar Charge Controller Descriptions:

LandStar series solar charge controller  is a new generation lighting controller for off-grid solar system, such as home system, traffic system, CCTV system. It adopts the most advanced digital technique and operates fully automatically.

Features:

  • 12V/24V automatic identify or user-defined working voltage.

  • With functions of current power calculation, it is convenient to view charging and discharging energy of each day, month, year and total value.

  • Wide input voltage range: DC8.0V---DC32V, compatible with 12V/24/ full voltage range.

  • Digital precision constant current control and the control accuracy are better than 2%

  • Maximum output efficiency of 95%

  • The rated output current can be adjusted at rated power and current range.

  • The max current output voltage can reach up to 60V

  • Charge control parameter, the load control parameter and the output current value can be set separately

  • Use standard Modbus communication protocol for TTL232 bus connection, communication protocol compatibility much better.

  • Fully encapsulated PCB, IP67 protection

  • Aluminum housing

Q:Solar controller 10a, a represents what
A (Ampere) is the basic unit of current expressed in the International System of Units, referred to as Ann, Symbol A. 10A refers to the controller can control the output device maximum current of 10A, select the load device when the device current can not exceed this value
Q:Solar controller can not charge what is the reason
Overdischarge protection Termination voltage: This is better understood. Battery discharge can not be lower than this value, which is the provisions of the national standard. Although the battery manufacturers have their own protection parameters (standard or line standard), but ultimately to close to the national standard. It should be noted that, for safety reasons, the general 12V battery over the protection point voltage plus 0.3v as a temperature compensation or control circuit zero drift correction, so 12V battery over discharge protection voltage is: 11.10v, then 24V system over discharge protection point voltage is 22.20V. At present, many manufacturers of charge and discharge controller are used 22.2v (24v system) standard.
Q:What is the system voltage of the solar controller?
General solar energy is now used LED lights, because the solar power is limited, with LED more power, the general 3, 4 watts when the general lights a 20 watts of brightness.
Q:How the inverter is connected to the solar controller
Inverter and solar controller connection requires intermediate storage device to connect, the general use of batteries, solar controller and battery connection charging, the battery and then connected with the inverter to its voltage, the elevated voltage and solar controller connection.
Q:What is the meaning of the 30A solar controller?
Solar controller above the marked 30A is the maximum current of the controller is 30A, the general solar controller has 12 / 24V10A 12 / 24V / 15A 12 / 24V20A 12 / 24V30A 24 / 48V10A 24 / 48V20A 24 / 48V30A 24 / 48V60A and so many Type of model. Customers can choose according to their own power size! The The When purchasing the capacity of the controller must be greater than the capacity of solar panels and load! The The
Q:What brand of solar controller is good
The State Administration of Quality Supervision, Inspection and Quarantine announced the Chinese brand-name products, the entire solar water heater industry is currently only selected eight companies, as follows: force Norit Shandong force Norit New Energy Co., Ltd. billion to Shandong billion solar energy Co., Ltd. Sunrise Oriental sun rain Lianyungang City sun rain water heater Manufacturing Co., Ltd. Huayang Jiangsu Province, Yang Yang Solar Co., Ltd. Huang Ming Shandong Huang Ming Solar Group Co., Ltd. Sang music digital Shandong Sang Le Solar Co., Ltd. Tsinghua sunshine Beijing Tsinghua sunshine solar equipment limited liability company Brilliant Jiangsu Huaiyin brilliant solar energy limited company
Q:What is a solar controller?
Can control the solar street light, the switch controller is the solar controller; domestic well-known brands should be far away power and the exchange of energy to the sun in the science and technology in Beijing; we are the power to do LED lighting business is brand goods
Q:Solar controller red light flashing
Look at the flash of red light shows what is the logo, the general controller should be a bad flash line
Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
In fact, as long as the voltage is 12V, with more power battery panels can be affected only the problem of charging speed.
Q:Choose a solar controller which need to have a few conditions
And some electrical function must be necessary. In one is from the manufacturer, the best choice of more formal relatively large manufacturers, and now the market is too messy. Stability is one, after the sale is also a.
