AC Coupling
Adding storage on the AC side of an existing inverter — the simplest way to retrofit solar.
Read definitionAmp-hour (Ah)
A measure of battery charge capacity; multiply by voltage to get energy in watt-hours.
Read definitionBattery Management System (BMS)
Electronics that monitor and protect cells, balancing charge and blocking unsafe voltages.
Read definitionBattery Wiring
How cells or packs are connected — in series, parallel or both — to reach a target voltage and capacity.
Read definitionC-rate
The speed of charge or discharge relative to capacity; 1C empties a pack in one hour.
Read definitionCapacity Degradation
The gradual loss of usable capacity as a battery ages and accumulates cycles.
Read definitionCycle Life
How many full charge/discharge cycles a battery delivers before capacity drops to a set limit.
Read definitionDC Coupling
Connecting storage on the DC side of a solar array through a shared hybrid inverter.
Read definitionDepth of Discharge (DoD)
How much of a battery's capacity is used in a cycle, expressed as a percentage.
