Class-T fuse
A high-interrupt DC fuse class used on battery banks so a short can clear without welding the fuse closed. Pair with a proper holder and cable ampacity. See tools & accessories and protect an EG4 12000XP.

Busbar
A thick conductive bar that joins multiple battery or inverter cables so current shares cleanly. Undersized busbars heat up and sag voltage under shop loads. Related: batteries, cables & hardware.
AIO (all-in-one)
An inverter/charger (and often MPPT) in one chassis. Handy for compact DIY, but confirm continuous watts, PV input, and battery voltage before you buy. Compare paths on inverters and 12000XP vs Solis hybrid.
Hybrid inverter
Grid-interactive inverter that can charge batteries and export or backup depending on settings. Best when the meter stays primary. Off-grid shop autonomy usually wants a different lane — see EG4 12000XP vs Solis hybrid.
LiFePO4
Lithium iron phosphate chemistry common in DIY 48V banks: long cycle life, stable chemistry, high usable capacity vs lead-acid. Shop reviews on batteries; size with size your battery bank; compare EG4 vs budget 48V.
SPD (surge protective device)
Hardware that clamps voltage spikes on PV or AC lines so lightning and utility events are less likely to kill an inverter. MidNite-class SPD is a common DIY pick — see tools & accessories and protect an EG4 12000XP.
Soft starter
A device that reduces motor inrush (compressors, well pumps, HVAC) so inverters do not fault on surge. Often cheaper than upsizing the whole inverter. See tools & accessories, garage shop, and size your inverter.
Server rack vs WallMount
Two 48V LiFePO4 form factors: WallMount hangs as a tidy wall pack; server-rack modules stack in a cabinet for modular kWh growth. Full compare: EG4 WallMount vs server rack. Intent: whole-home backup.
MPPT
Maximum Power Point Tracking — squeezes more watts from an array than PWM. Most modern AIOs and hybrids include MPPTs. See inverters, solar panels, cabin off-grid, and size your inverter.
Split-phase
US 120/240V service common in shops and homes. Confirm inverter output before tying into a panel. Related: 12000XP install, size your inverter, garage shop, whole-home backup.
