Typically for large-scale photovoltaic off-grid power systems, the specially designed high power photovoltaic intelligent controllers, multi-channel input array of PV modules, convergence to one output. For the battery charge and discharge management, according to the battery pack voltage changes, it automatically controlling components and modules connect or disconnect to maximize the use of solar energy, and also avoids battery overcharge or over discharge problem. In addition, through the power controller multi-input, multi-chip components can be simply connected the controller to solve the traditional large-scale systems require multiple small controllers, complex parallel wiring, to avoid errors caused by lining issues. According to off-grid photovoltaic power system and the different battery design, solar controller are divided into 24V, 48V, 96V, 120V, 192V and 240V and other specifications to meet different users' needs or program designer

We manufacture and export solar water heaters (160l-300l) as common solar water heater, whole-day intelligent solar water heater, however, you may get their details (pictures, specification, fuction, packing sizes, and others). Your users don't pay any money when they use them after they bought, except for cold winter when they should use electric heater by electric power which you may pay the money for power only!

Low-pressure sodium lamp (LPS), an electricity source of using the low-pressure sodium vapor (work vapor pressure no more than a few pa), to discharge and generate the visible light. Since the invention in 1930. The Low Pressure Sodium lamp has consistently maintained its enviable position as the most efficient light source available. Germany lighting experts OSRAM is an important member of the Siemens Group, which is one of the two largest manufacturers of the electric light. LPS are famous for the most efficient light sources. For example, the 36W LPS system designed and collocated by our company, used in 8m-height road lamp system, the exposure on the ground is 24.5 Lux, however, the 85W energy-saving light at the same height, only has 4.4 Lux. The life span of low-pressure sodium lamp depends on the number of ignition process, typically 18,000 hours. Light decline is smaller than other sources, can be reached 80-85% Luminous fiux at the end of the life. At present, our company has developed the LSP system with the characteristics of high light efficient, low temperature increase, lightweight, small self-consumption and large power factor and other characteristics. Compared with the common light source, it can save the electricity above 70%. It is especially suitable for the solar road light, tunnel lighting and highland cold special environmental situation etc. Solar energy low-pressure sodium lamp system is the best choice of solar lighting field. 12 pieces/carton.
Working Principle: the current from the sunshine to the solar battery plates begin to recharge the battery through the invert controller and convert into the DC/AC for the use of the appliance, or through the grid inverter directly to the power supply network. Solar photovoltaic system was made of the solar cells (group), solar controller and batteries (group). If the output power is AC 220v or 110v, the inverter is needed. Linux brand battery plate components conventional configuration: solar unit is a device of single power available, which is equivalent to a battery of about 0.5v,While battery plate components were the equivalent of batteries group of more batteries serial or parallel connectivity. The number of components usually depends on the system voltage (battery voltage). Usually, it is the1.4-1.5 times compare to the battery voltage. Power range: mono/multi-crystalline silicon solar cell mainly include several types of 2W, 3W, 4W,5W, 20W, 25W, 30W, 35W, 40W, 45W, 50W, 55W, 60W, 65W, 70W, 75W, 80W, 85W, 90W, 95W, 100W, 110W, 120W, 130W, 140W, 150W, 165W, 180W, 200W, 240W etc.
