The amount of electrical power required to keep an inverter ready to produce electricity on demand.

The first stage of three-stage battery charging. Current is sent to batteries at the maximum rate they will accept while voltage rises to full charge level.

A deep cycle occurs when a battery is discharged to 50% of its capacity (50% depth of discharge). A deep-cycle battery is one that is intended to be deeply discharged and charged repeatedly.

A control circuit that stops the flow of electricity from batteries to loads when battery voltage drops to low levels. This prevents over-discharge of the batteries.

The second stage of three-stage battery charging. Voltage remains constant and current tapers as internal battery resistance increases during charging. This ensures complete charging.

The type of electrical power supplied by the power utility. The unique characteristic of this form of electricity is that it reverses direction at regular intervals. For example, 120 Vac 60 Hz power r [..]

Refers to the air temperature around the inverter and batteries, which will affect the output power of your system.

One amp of electrical current flowing for one hour. Expresses the relationship between current (amps) and time. (Ohm’s law: A = V/R)

The current-carrying capacity of an electrical conductor or device, expressed in amperes.

A lead acid, maintenance-free battery.
