Zhengzhou conley of electronic power co., LTD., founded in 2000, professional development, production, sales of 2 v, 4 v, 6 v, 12 v four series and maintenance-free lead-acid battery, gel battery and electronic charger, etc. Products are widely used in security alarm system, fire alarm system, building intercom system, elevator emergency evacuation system, emergency lights, antenna, power sprayers, electronic said, children, cartoon gas mould, washing machine, rotary table, parking lock, flashing lights, traffic lights, dc panel, solar energy, wind energy, UPS, EPS, etc for electrical system. The following corlida electronic power co., LTD. To tell you about the quality of solar battery identification methods.

　　According to such standards, methods to identify and choose solar energy will not be wrong!

　　Solar water heater is a large household durable goods, once bought home may not change for more than ten years. The material of solar energy water heater, technology, craft is different, service life has 3 years, 5 years, also have can use more than 10 years. As a hot water supply facility on the roof, the new and old solar energy does not affect the beauty of the bedroom at all, do not need to worry about the issue of replacement. So, from a household investment perspective, buying solar energy that lasts more than 10 years is the most cost-effective.

　　Vacuum tubes, insulation layer, liner and fittings are the main factors affecting solar life.

　　Vacuum tube: the vacuum tube is the core component of solar water heater, its function is to convert the absorbed solar energy into heat energy, and make the water inside the tube warm up and circulate. The quality of the vacuum tube directly determines the performance of the whole water heater.

　　Common vacuum tube vacuum degree is low, small power vacuum unit, short exhaust time, vacuum degree only 10-1-10-2pa. Vacuum tubes cannot store heat for a long time. After being placed outside for a long time, the heat insulation performance is not as good as that of thermos bottles. Coating technology is backward, plus the technology is not good, emissivity ratio is high, heat dissipation is big, same bask in a day, hot water still does not have high quality solar energy half.

　　To make the battery system has high reliability, the first thing to correctly choose the battery, battery on the design of UPS and communication are different: some battery has good circulation features; Some batteries are suitable for starting; Some batteries are suitable for low temperature environment. Some batteries are suitable for low current discharge and so on.

　　When selecting batteries, it is very necessary to understand the differences between various batteries in technology and in use. First of all, it is necessary to fully understand the user's demand for products. Such as back-up power system capacity requirements, frequency of use, use of environment, the main purpose, service life and reliability requirements, instantaneous discharge rate, the specifications of the rectifier and other performance requirements related to battery.

　　Second to understand the battery's performance, including product design parameters (the model of battery, appearance size, rated capacity, rated voltage, weight, volume, weight than energy than energy, design life, the number of positive and negative plate piece, the positive and negative plate thickness ratio, the density of the electrolyte, the type of plate, plate gate materials, etc.), product performance parameters, actual use of the product life, install and use environment, different models of performance and price, different kinds of product warranty, etc.
