How does a base battery work?

This process is called grid-balancing. Base batteries deploy energy to the grid faster than any other service, which is how Base is able to recoup the cost of the battery equipment and keep prices low for homeowners. The charge level of your Base battery will naturally fluctuate over time, rising and falling throughout a multi-day cycle.

What is a base battery system?

The Base battery system is built for performance and reliability. It combines a high-capacity lithium iron battery with intelligent software to optimize energy use. The Base battery system has three main components: the battery pack, inverter, and hub. The long white unit is the battery pack. We mount the battery pack on the ground.

What is a battery energy storage system?

A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.

Do base batteries run in two directions?

Base batteries run in two directions, which is how Base is able to keep costs low for homeowners. The batteries charge during off-peak hours, like midday and late at night, when energy is more available and demand is low.

How long does a battery storage system last?

For example, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity will have a storage duration of four hours. Cycle life/lifetime is the amount of time or cycles a battery storage system can provide regular charging and discharging before failure or significant degradation.

How long does a single unit Battery last?

At low energy use, the single-unit Base battery can protect an average household for 20 hours. At moderate energy use, backup duration is typically 12-14 hours. You can extend this time by using fewer power-hungry appliances. For more specific information based on your battery configuration, check our specs here.
