On and Off Grid Inverters
On & off grid inverters are tied to the utility grid and can also provide back up power if the utility grid fails. These inverters are generally used in residential and commercial applications.

More about On and Off Grid Power Inverters
On and Off Grid Solar Power Inverters provide grid-tie (selling power back to the utility company) but also have the added features needed to provide backup power when the electric utility grid fails.
Since substantial power may move across On and Off Grid Inverters, attention must be paid to self- heating and efficiency. To minimize energy loss to heat, On and Off Grid Inverters have special circuitry to match the voltage and the frequency of your local utility. In addition to managing the utility power, On and Off Grid Inverters must manage the battery power subsystem.
On and Off Grid Inverters usually include some form of battery charging and battery management circuitry. Batteries have specific charging profiles. Depending on battery state of charge, and their temperature, batteries have optimal charging rates and if not properly controlled they can have their life shortened. An On-Off Grid Inverter should incorporate this circuitry.
Another consideration is the voltage of the backup battery power storage. High power On and Off Grid Inverters tend to use higher voltage battery assemblies. Using higher voltage batteries menad less current has to be ‘stopped up’ household level voltage – typically 110V to 120 V Alternating Current. On and Off Grid Inverters usually have data ports to allow monitoring of operation.
