If you are experiencing frequent grid outages and have critical operations or perishables that always require power.
By storing excess solar production during the day and utilizing it at night, you're maximizing financials by avoiding partial credits for what would normally be sent back to the grid.
By adding an additional battery to the system, you're able to leverage self-metering while having extra storage to provide confort at any time of the day. With all other aspects of the project already accounted for, the cost of adding an additional battery is rather favorable.

Can I go off grid? We are very fortunate to be connected to a grid, so we want to utilize it. Almost all systems in our area our grid tied. To go fully “off grid” is a very expensive process and truly utilized for situations where grid connection is not in the area.
Can I charge the battery during the day and use the power at night? Technically, yes. However, we operate mainly on fixed rate bill, so this function is not typically used in our area.
Do I backup my whole house or just a critical loads panel? We can offer both, but in most cases, you just need to back up the most critical loads to get you through an outage. Backing up an entire house requires a larger investment.
Can I back up my A/C unit and other large electrical loads? If you were to back up large electric loads, such as HVAC systems, the battery will deplete rather quickly. That said, we normally do not recommend backing up non-critical loads such as HVAC.
