According to zone flex P300 specs sheet, it uses PoE only. If I'm going to plan for solar power for this equipment, how can I calculate its the power consumption? and also voltage rating? do I need Solar power PoE switch?
When using solar power watch out for the DC coming out of the Battery as new batteries will provide up to 15~16VDC (Had to use a 12V regulator on the output of the battery). As for a 12VDC/220VAC, No solar power company recommended that solution.
From a personal opinion, solar power is the last option that you should consider..
