KSTAR: Как работят акумулаторните системи?⚡️

How do battery systems work?
The main operating principle of a residential or commercial/industrial energy storage system is almost the same. The difference lies in the amount of energy that is stored and transmitted.

The system can be powered by electricity from sources such as solar panels, as well as from the grid during periods of lower energy demand (off-peak) when the price usually drops significantly.

Energy is stored in the form of direct current (DC), which is later converted to alternating current (AC) by a power conversion system (PCS) or inverter to power appliances and equipment in a home or commercial facility.

The Energy Management System (EMS) takes care of actively controlling the charge and discharge cycles to ensure the best system outcome and maximum gain for the user. C&I systems are also commonly used to interact with the utility grid to provide grid services such as frequency regulation or energy arbitrage.

Tips for long battery storage life

Maintain temperatures within recommended temperature ranges
The battery datasheet (downloadable with each product) includes a "Ambient Operating Temperature Range". It is important to pay attention to both the lower and upper limits. If the battery is heated too much, the battery life will be reduced by up to 50%.

DOD settings
The DOD, or usable depth of discharge, should be set from the default 90% to a value in the 60% - 80% range. Or increase the minimum battery condition value from 10% to 20 - 40%.

Charging to 100%
Occasional (twice a month) or regular (daily) charging to full capacity is very beneficial for batteries.

Winterizing the battery
One way to extend the life of a battery is to charge it to 100% and completely shut it down over the winter. However, this will extend the payback period of your investment.

Longer discharge and charge times
Spread the power surges over the whole day. For example, delay the start of your appliances - jumping discharges are just as damaging to batteries as jumping or fast charging.
