OutBack EnergyCell 1000XLC

Since the beginning of 2017 the residential energy storage market has grown 77% according to

an EnergySage report*. While Hawaii and California are still the dominant markets, recent policy

changes have dramatically increased installations in several other states such as Nevada and

New York.

The high cycle life and partial state of charge (PSoC)

operation of Lithium-Ion technology has created a stir

in the market. However, there are some drawbacks

and concerns for users. Our 2019 voice of customer

(VOC) survey has a consistent trend when it comes to

choosing energy storage for renewable energy

applications. While advanced energy storage

solutions like lithium-ion continue to grow in

popularity, in the past year 79% Off-grid systems were

deployed using Lead-Acid technology and 60% for Grid-Tied battery backup. VOC data

reflects that customers continue to prefer reliable Lead-Acid technology over Lithium-Ion due to

lower upfront cost, safe operation, recyclability and the fact that no BMS is required.

With the new 1000XLC (High Capacity Lead-Carbon) addition to our EnergyCell line, OutBack

now offers an energy storage option that provides the best of

both worlds. The 1000XLC stands out from other Lead-Acid

batteries due to its advance carbon additive to the negative

plate, improved anti-corrosion grid, enhanced surface adhesion

and introduction of new separators. Combined with the

advanced technology preventing stratification and sulfating,

which results in extending the life of the battery and increasing

efficiency.

The 1000XLC delivers:

 10-year cycle life including partial state of charge (PSoC)

operation at 50% DoD / 25c

 10-year standard warranty

 17-year standby life at 25c

 A built in OutBack Power branded cabinet with great

aesthetics

 All the safety features of lead-acid technology

 A modular design stackable up to three systems for a total of 177kWh of energy

 Competitive price

The 1000XLC is well advanced beyond traditional Lead-Acid, it actually makes more practical

sense to compare with advanced energy storage offerings instead.

To achieve the same effective energy capacity of a single XLC system, you will require between

6-10 48V modules of the lithium ion offerings. Per the chart below, the upfront cost of Lithium Ion

makes the 1000XLC top choice for best cost per kWh delivered in this energy density footprint.
