| Low Battery Protection A control circuit that stops the flow of electricity from batteries to loads when battery voltage drops to dangerously low levels. Modified Sine Wave Also called a modified square wave, this type of waveform emulates a sine wave using a series of small steps to create a curve. Off Grid An electrical system that is not connected to a utility distribution grid. Overload/Overcurrent Protection A control circuit designed to protect an inverter or similar device from loads exceeding its output capacity. (A fuse, for example, is an overcurrent protection device.) Parallel Wiring Batteries or PV modules, wired together to increase ampacity, while voltage remains constant. Two 100 Ah 12 Vdc batteries wired in parallel will form a 200 Ah 12 Vdc battery bank. Photovoltaic (PV) Array Commonly referred to as solar panels, the PV array collects energy from the sun and converts it into DC energy. |
