What is a battery energy storage system?

A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.

What is a battery discharge limit?

The discharge limit is how you can control how much battery power you use on a regular basis. Most likely, this will be set up for hours in which there is sun. If you are using grid power and not PV to recharge your battery, then you would likely set the charge window to match up with the cheapest rate for utility power.

What is the difference between rated power capacity and storage duration?

Rated power capacity is the total possible instantaneous discharge capability (in kilowatts [kW] or megawatts [MW]) of the BESS, or the maximum rate of discharge that the BESS can achieve, starting from a fully charged state. Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity.

What is a charge and discharge limit?

The charge and discharge limits determine how much power the battery is allowed to use or charge with during the time windows that you set. If you set it to the maximum, the system will discharge up to 6kW until the battery is drained to the Overdischarge SOC or the end of the "discharge" time window is reached.

What is a battery energy storage system (BESS)?

Battery Energy Storage Systems (BESS) are pivotal technologies for sustainable and efficient energy solutions.

What parameters control the depth of discharge?

When no mains power is available, and the system is in inverter mode, the following parameters control the depth of discharge: Low cell signals from 3rd party CAN-bus enabled BMS's are ignored. The system relies on the automatic protection inside Lithium cells to trip. What about the Sustain mode?
