1.   How do I decide which system is right for me ?

For protection from long outages, include a generator or solar panels in your Must solar system. Shorter outages can be handled by a battery-only system.

2.    Where my system will be installed ?

Must solar systems are usually wall-mounted near a home's main electrical (circuit breaker) panel.

3. How do I install my system ?

A solar backup inverter is connected to a home electric system , we will supply detailed installation manual and videos for our customers .

Sealed and maintenance-free battery USES the latest design fully sealed structure and in the ninety s modernization production process.Has the high performance, long life, no pollution, free maintenance, safe and reliable performance.When charging, electrical energy into chemical energy, discharge chemical energy into electricity.Battery during discharge, the metal lead is negative, the oxidation reaction, oxidized lead sulfate;Lead dioxide is positive, reduction reaction, reduction of lead sulfate.When used in dc rechargeable batteries, lead and lead dioxide generated poles respectively.Remove the power supply, it back to the front of the discharge state of dynamic balance of the inner of the chemical battery.Lead-acid batteries is to repeatedly charging and discharging of battery, also known as secondary battery.Commonly used batteries are divided into four categories, respectively, the common battery, dry battery, wet charge batteries and battery four without maintenance.

Q:District power equipment installation tender, the need for the conditions of the tender unit
Power installation qualification certificate: one, two, level threeLevel 1: mechanical and electrical equipment installation engineering contract one class or the transmission and substation engineering contract qualification of an independent legal person to build more than 220 thousand volt classTwo level: mechanical and electrical equipment installation engineering contract two class or transmission and substation engineering contract qualification of independent legal person (220kV and below the transmission line, the construction of the substation) twoThree level: mechanical and electrical equipment installation engineering professional contract three level or transmission and substation engineering professional contract level three qualification of independent legal person (110kV and below transmission line, substation (room) construction)
Q:Ask the expert about the design of the power system diagram, 6kV side of the electrical equipment how to supply
For 35/6KV step-down stationEach line with the 6/0.4KV transformer, or 6KV equipment (such as 6KV synchronous motor), are the load of the stationSo, there are 6KV devices, single occupancy 6KV bus on a certain line can be
Q:Under the same voltage level, the rated voltage of the equipment is not exactly the same
And some appliances have no effect. For example: switching power supply, it can work in a wide range of voltage, the output voltage remains unchanged. It should be noted that, as long as the manufacturers in the normal operating voltage range, generally will not cause the state of work and security issues, can be assured that the use of.
Q:Private enterprises must be free transfer of power facilities
The new user electrical facilities investment, after the investment asset is transferred to the power supply enterprise, according to the need for "business rules", the actual state of electricity contribution, interface division, maintenance management ability, after consultation by both parties to determine.
Q:What is the GIS in power system
Popularly speaking, GIS is often we can see the switch station, also known as high-voltage distribution device.There are three types of high voltage power distribution equipment: the first is the conventional air distribution equipment, referred to as AIS. The bus bar is exposed directly to the air, and the breaker can be provided with a porcelain column or a tank type. This type is used in Gezhouba Dam power plant.
Q:In order to ensure the normal operation of the power system and equipment to achieve a grounding
The grounding of power system and electrical equipment can be divided into working grounding, protective grounding, grounding and repeated grounding.
Q:What is the redundancy of electrical equipment
Disk duplex: a I/O controller is added to the mirrored disk to form a dual disk to improve bus contention.RAID: cheap redundant array of disks (Redundant array of inexpensive disks). As the name suggests, it consists of a number of disks, through a controller to coordinate the movement of a single data flow into the disk. The RAID3 system consists of 5 disks, in which 4 disks store data, and the 1 stores the check information. If a disk fails, you can replace the disk on the line, and through the other 3 disks and check the disk to re create the data on the new site. RAID5 will check the information distributed on 5 disks, so you can replace any disk, the rest with the same RAID3.
Q:What specific enterprises and units are used to test the power of the equipment ah
Electrical installation company, has installed for repair, test qualification. The test is power detection.
Q:What equipment is necessary on the list of electrical engineering equipment?
MS-300D geodetic network grounding resistance tester, MS-101D anti-interference dielectric loss automatic measuring instrument, MSGK-E high voltage switch dynamic characteristic tester, MSBL-IV arrester characteristic tester and other equipment.
Q:What is the meaning of the high - voltage high - voltage device in power system, which is mainly used to protect the situation,
That response to the power parameters is high frequency, this requires high cycle splitting device, tripping the corresponding circuit breaker, to remove the part of power grid connected or separated from the original into two or more power, get rid of the accident or the narrow scope of the accident to
