UNDERSTANDING UPDATES TO IEC 61215 STANDARDS

Explosion-proof standards for battery energy storage cabinets
The NFPA 855 standard, developed by the National Fire Protection Association, provides detailed guidelines for the installation of stationary energy storage systems to mitigate the associated hazards. [pdf]
Factory roof photovoltaic panel installation standards
If you wish to avoid the need for planning permission, the panels must:Not be installed above the highest point of the property (not including chimneys)Be fitted in a way that least affects the external appearance of the property and the surrounding areaNot protrude more than 200mm from the surface of your roof [pdf]
How much tilt should photovoltaic panels have to be to be effective
To optimize performance, tilt your panels at an angle that is 10-15 degrees less than your latitude. For example, if you live at a latitude of 40 degrees, set your panels at about 25-30 degrees. [pdf]
IEC for electrochemical energy storage systems
IEC 62933-1:2018 defines terms applicable to electrical energy storage (EES) systems including terms necessary for the definition of unit parameters, test methods, planning, installation, safety an. [pdf][FAQS about IEC for electrochemical energy storage systems]
