.
AC
Alternating Current
Ah
Rated battery capacity specified in Ampere-Hour.
AC Run To
T
he level the solar regulator will charge the battery to before the inverter
switches back to battery power
AC Source
The primary AC input that is connected to the inverter, e.g., Mains Grid or
Generator.
Bat Run To
The
level the battery discharges to before switching to mains power.
Bat Off At
The voltage at which the inverter will disconnect the load from the batteries.
DC
Direct Current.
Grid Connected
A system that is connected to the grid.
Inverter
Is an electronic device or circuitry that changes direct current (DC) to alternating
current (AC).
Inverter Mode
The inverter is producing AC from the batteries.
LED
Light emitting diode.
Load
Electrical appliance or device to which an electrical voltage is fed
Off-Grid
A system not connected to the grid
Solar Array
A collection of Solar Panels.
PV
Photo Voltaic solar power.
State of Charge
(SoC) Referring to the battery charge condition.
Sealed Battery
A lead acid battery with no access to the electrolyte - either valve regulated or
gel. No hydrogen gas discharge during normal operation.
Flooded Battery
A lead acid battery with access caps for maintaining the electrolyte - replacing
water lost during recharge operations. Hydrogen gas discharged during normal
recharge
SoC
State of Charge is the amount of charge in the battery bank expressed as a % of
the battery capacity. When SoC = 100% the battery is fully charged. When the
SoC is 50% then the battery is half charged.
