What We Do | Grid-Paralleled

Grid-Paralleled Systems combine all the same technologies as the Grid-Connected accept that they have no interconnection with the utility. Systems are placed side-by-side and deliver electricity to a group of critical load or preferred load appliances, often being the primary source of electricity. The appliance may have the ability to reconnect to a secondary outlet, which draws on the utility. These loads can be designed to support critical loads such as refrigerator, water heater, freezers, and essential communications and lighting; or they can simply be designed to offset peak consumption such as air conditioning and the washer and dryer. These arrangements can be very affective at curbing power drawn for the utility; and under a time-of-use agreement, there can be substantial financial advantages.

Grid-Paralleled systems are limited in size, essentially because peak capacity must match peak usage. The alternative is to add energy storage to the system.

Mixed with energy storage, this arrangement can almost be as effective as grid-connected. Capacity match is no longer a factor in system engineering. The total goal is to match system storage capabilities with average daily usage. This is great for matching typical energy usage requirements such as electronics and appliance used in the late afternoons. On top, you have the reassurance of stored energy in the event of supply disruptions like black outs.

The primary reason that this type of arrangement would be chosen is because not all utilities have net-metering laws in effect. And a paralleled system does not require interconnection or the approval of the local utility. At this time, Grid Paralleled systems must be purchased. Rent or lease is not an option.
