How a battery backup inverter is wired to the grid, how the backed-up circuits wiring is moved without going into the house, and how the inverter works. Why a charge-controller is needed, and how the MX-60 works. Peak power tracking (PPT) is not explained, but it essentially uses a coil to convert higher voltage from the panels (which would otherwise be wasted, since the batteries always operate at 24 or 48 volts) into extra amperage (current). Usually, eg, 100 amps in at 80 volts (no-load voltage is 120) is converted into 130 amps at 53 volts. UL-1741 requires all inverters to "island" if the grid goes down or if the voltage is irregular (happens more often than you might think!). Battery Backup inverters island, just as grid-tie inverters, but they are able to go to the battery pack for power when the grid is cut off, even when the panels are not producing. These inverters are even "smart" enough to start a diesel genset, if it's attached; but no need to do so if you have enough batteries to last until the next sunny day.
