    In the previous ATESS white paper, we have introduced the automatic power distribution function of the ATESS EV charger. There are usually household or office appliance in the installation site, and the installation is limited by the total power distribution capacity. Then what can we do to ensure normal use of the load and with the premise of not exceeding the total power? The key is that the EV charger needs to have dynamical adjusting function, to automatically tune the charging power according to the load capacity. ATESS solution is as follow:

    With the rapid expansion of the market demand for ESS, the application scenarios are getting more extensive, resulting in more load types that storage inverter has to cope with. The most common question we’ve been asked is that when the project site has both single-phase and three-phase load, how should the storage inverter be connected? As we all know, connection of single-phase load will cause output power difference in each phase, which leads to imbalance between the three phases, bringing some negative effects to the inverter

    Insufficient space or power? Let "PV storage+charging" settle it -Solution for EV charging station

    2020.07.10

    Electric vehicle with no doubt has become a trend in today’s global automobile industry and an integral part of people's green lifestyle. Therefore speeding up the construction of charging infrastructure has also become an urgent demand. The charging infrastructure as an important supporting facility, is of the most significance, as its quantity and distribution directly decide the charging convenience.

    Data speaks louder, upgrade grid-tie system to storage makes more money?

    2020.06.19

    In recent years with the popularization of new energy, the scale of grid-tie system has increased significantly. However, due to the primitive power grid construction in a lot of areas, decreased or canceled Feed-in-Tariff, and low PV self-consumption rate, the phenomenon of feed-in power limitation and solar station abandonment has frequently occurred, resulting in resource waste, investment return reduction or even deficit. In view of this situation, our company put forward the energy storage AC-couple retrofit scheme and has been widely applied. Grid connected energy storage system can store the surplus power and improve the self-consumption ratio. It is applicable to the scenarios that PV power cannot be sold to utility grid, and self-use electricity price is higher than the feed-in price, or solar power generation and consumption are not in the same period.
