9.3. How to Calculate the Operation Time
●What is the depth of discharge (DoD)?
To extend the battery-life, the power station set the 90% DOD, which means that
only 90% of the battery capacity can be discharged. 10% of the energy is reserved to
avoid damage to the battery due to over-discharge.
η indicates local inverter eciency. DOD=90%, η =90%.
10. UPS
10.1. UPS Description
An uninterruptible power supply or uninterruptible power source (UPS) is
an electrical apparatus that provides emergency power to a load when the
input power source or mains power fails. A UPS differs from an auxiliary or
emergency power system or standby generator in that it will provide near-
instantaneous protection from input power interruptions, by supplying energy
stored in batteries, supercapacitors, or ywheels.
10.1.1. FYI (For Your Information)
Max. capacity retention indicates the limit of capacity of the unit that can be
recharged by grid, if you set the Max. battery capacity at 80% at Time Control
UPS Mode and Customized UPS Mode then AC300 could be charged to 80% via
grid. The rest of the 20% capacity will be recharged via solar panels.
