The scenario
An off-grid installation powers AC loads from a 48V DC bus charged by a solar PV array and battery bank, with an 8 kW hybrid inverter and a backup generator connected through an ATS.
What is in this drawing
Read the decisions behind it.
01
Use a 48 V DC bus to connect the PV array, battery bank, and hybrid inverter.
02
Place an automatic transfer switch between the inverter and generator for seamless backup.
03
Protect each DC source and AC load circuit with appropriately rated breakers.
04
Route AC power through an energy meter before the distribution bus.
Use when documenting or reviewing off-grid or backup solar PV systems with battery storage and generator transfer.
