Energy arbitrage in battery storage means charging a battery when electricity is lower-cost or lower-value and discharging it when electricity is ...

Commercial battery storage ROI is calculated by comparing the project’s lifetime net cash benefits with its total installed and operating costs. A...

The most common home battery installation mistakes happen before the system is switched on: the load has not been measured, components have not be...

A 2MWh battery system is not automatically twice as useful as a 1MWh system. The right choice depends on the required discharge power, runtime, ta...

Battery storage fire safety is not proven by one certificate, one suppression component or a chemistry label. For a commercial or utility-scale pr...

PCS, BMS and EMS are not interchangeable terms. The BMS protects and supervises the battery, the PCS converts electricity and controls AC-side pow...

LiFePO4 batteries are lithium-ion batteries for transport purposes; their chemistry does not remove dangerous-goods obligations. Importers, distri...

Industrial facilities do not need a microgrid simply because they have solar panels or batteries. They need one when the cost of interrupted produ...

Data center battery storage can strengthen resilience, but it must be designed around the load, transfer sequence and failure modes of the facilit...

The cost of a commercial battery storage system cannot be reduced to one price per kilowatt-hour. Two projects with the same battery capacity can ...

State of charge (SOC) tells you how full a battery is. Depth of discharge (DoD) tells you how much of its capacity has been used. They describe th...
