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 diers 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)
Battery SOC High indicates the limit of capacity the unit which can be charged
by the grid. If you set the Battery SOC High to 80% in Customized Mode, the
EP500Pro will be charged up to 80% from grid power. The remaining 20% will
be charged via solar panels (PV). This allows a discharged EP500Pro doing UPS
duties to quickly recharge from the grid when it comes back online to a certain
percentage before switching to solar panels to insure there is ample power for
the next power outage, but still charge via solar for clean and free energy.
