Myanmar, the largest country in Mainland Southeast Asia, is one of the least developed nations, with only 50 percent of households connected to the public grid. Solar energy as an important solution to resolve the energy crisis and climate change wins its due attention in Myanmar.

With the expansion of blackouts, Myanmar’s severe power outage poses a big problem for the routine operation of public recreational facilities. Previously totally powered by fuel generators, a playground in Lashio, the largest town in northern Shan State, is deeply troubled by the nearly daily power cuts and the 3 or 4 power supply hours each day are far from meeting the power demand. Meantime, the soaring fuel prices make the cost of using fuel generators too high. Thus, to alleviate the problem, the owner of the playground actively seeks solutions and utilizes PV to generate electricity.

A PV energy storage system includes solar modules, controllers, inverters, batteries, loads, and other equipment. Today there are various technical routes, but whatever it is, the energy needs to be collected at a certain point. There are mainly two topologies in the market: DC coupling and AC coupling. Then you might ask: which configuration should be more preferred, AC or DC coupling? Today we are going to reveal the pros and cons of both.

With the penetration of energy storage systems, today the service life and operating environment of lithium batteries are drawing more attention. In the past years, ATESS has been committed to the research and development of lithium battery BMS. By the end of 2021, we have finally delivered a satisfactory result: The ATESS next-generation battery system integrated intelligent active balancing technology is officially launched. The application of active balancing will ensure that the battery system always is in the best performance condition, hence improving the service life of the battery, also it can make the battery system adapt to diverse load conditions, meanwhile greatly reducing the cost of maintenance, increasing system reliability, stability and load adaptability.  

South Africa has been plagued by power shortage for years. The main power source is coal power, short supply of the coal resource leads to high electricity price. Due to the long-distance transmission, approximately 10-12% of the power is lost during the process.Some people living in poor power condition would have to turn to diesel generators. However its high cost and harmful emissions makes it the last choice in the long run. Solar power, being environmentally-friendly and not affected by transmission power loss , has been popularizing by the South African government, and many households and businesses have put solar panels on their rooftop. Meanwhile as a trend for solar industry, energy storage system has also attracted more eyes of local customers.
