Years of war has severely damaged Cambodia’s power sector, the inducing high electricity price and low energy access has closely impacted local factories’ production capacity, profit etc. One garment factory there used to rely on a 400KVA power grid transformer, yet the whole factory peak load was 600KW, so the diesel generator had to be turned on when load capacity exceeded 400KW. Extra high expense and pollution caused by the generator are also headaches. To resolve such problem and maximize production profit, owner of the factory opted to utilize their abundant light resources, to retrofit his existing power system to an ATESS integrated solar energy storage system.

Why do we need load balance when using multiple chargers?
When install multiple chargers in public stations, if the output power of these chargers is not managed, the total power might exceed the maximum power of the power distribution switch and cause a trip. Therefore, performing load balance for multiple chargers is a must.

Today in response to the call of green travel and to alleviate pollution of automobile exhaust, electric vehicles have gradually seep into people's routine life and become a necessity. As things are at the moment, the main power source for the popular electric vehicles in the market is utility grid, however, the increasing number of electric vehicles will inevitably cause grid pressure and lead to some kind of limitation for EV charging. To resolve this conflict and also improve the efficient use of energy, solar charging is introduced to ATESS EV charging technology.

Today solar energy storage inverter undoubtedly has been a common choice for residential and industrial power supply, for now there are two ways to construct medium to large-scale applications: one is to use single high-power inverter; the other is to use several smaller inverters in parallel. Single high-power inverter might have disadvantage in volume, quality, installation and other aspects. In addition, the reliability of single high-power scheme is relatively poor, one error may make the whole system paralyzed. Therefore, the technology of parallel connection is worth being applied in wider field.
