• Sigenergy systems
• Main metering panel is same location as main switchboard.
• Battery system location is not hard to find, or in a large building.
• Not installed in a BESS room, or BESS room only has 1 door. 
• Designed for 2 x inverters/BESS. 
• DC and AC cables not in the same wiring enclosure without an insulating barrier (conduit).
• Inverter and equipment to be operated in event of a shutdown not necessarily close to each other. 
• Power sensor or no power sensor. 
• There may be DC cables installed in ceiling space. 

If your installation falls outside this scenario, additional labels will be required.

• Assume no 3rd party inverters. 
• Not designed for solar only (must have battery). 
• Connected to MSB directly or to Sub board. 
• Generator or no generator
• No switchboards electrically connected between MSB and switchboard IES is connected to.
• Inverter adjacent to switchboard, or not.
