An off-grid inverter is a device that converts DC power from batteries into AC power. One of their essential features is that their DC input is available only for limited DC voltages, such as 12V, 24V, and 48V, as they are connected to battery outputs that come in these DC voltages.
Not every off-grid solar system needs an inverter. An inverter is not needed if power is to be provided to DC loads only. However, there are two types of inverter-less off-grid photovoltaic systems: one with a battery bank and one without. Grid-tied and off-grid photovoltaic systems use different kinds of inverters.
Another essential feature of off-grid inverters is that their DC input is available just for a limited number of DC voltages (12V, 24V, and 48V). This is because the inverter input is connected to the battery output that comes in these DC voltages.
The inverter must also match the system voltage (i.e., the voltage of the battery and the charge controller). In off-grid solar electric systems, an inverter can be designed to power either a single AC device or all the AC loads to be plugged into. The inverter must be sized to handle the peak electricity demand.
A grid-tied solar inverter converts DC voltage from the solar array into AC voltage, which can be used immediately or exported to the utility grid. The inverter is the heart of any grid-tied solar system.
2. Typical Off-Grid PV Power System Configuration Off-grid PV power systems can range from a single module, single battery system providing energy to dc loads in a small residence to a large system comprising an array totaling hundreds of kW of PV modules with a large battery bank and an inverter (or inverters) providing ac power to the load.
