Zapp Star Battery Prices
Recommendations based on our experience
Off-Grid
The majority of our customers live off-grid. The difference
between our off-grid customers and those using other batteries is that
ours do not have to make major lifestyle sacrifices. They use
appliances pretty much like those who live on the grid.
While certainly every household is different, we have found
that our off-grid customers usually do fine with any of the three
systems in the table below with 5-hour output ratings of 12 kWh
($14,500). The number of solar panels needed to make systems work
through the darkest months of the year varies by lattitude. The total
cost, including inverters, solar panels and other gear is roughly
$20,000 in Arizona. The most northern U.S. lattitudes pay up to $30,000
for the same functionality.
Grid Tie
We recommend half the number of batteries for grid-tie
configurations--the two configurations rated at 6 kWh in the "Watts:
5-hr output" column.
The unique aspects of our battery make our recommended
configuration quite different than the usual grid-tie. The household
runs directlly from the batteries. Solar charges the batteries. Only if
all household demands are met, and the batteries charged, is the excess
power sent to the grid. This is best for the household, because
utilties do not pay nearly the rate for electricity than they charge to
consumers. It is better for utilities, too, because the variability of
the power they receive is reduced. All of this possible because Zapp
Works batteries don't degrade from use.
Unique batteries, so configuration is also unique
Unlike any other battery, you can completely discharge Zapp
Works batteries without shortening life. Also unique: Charge at a
higher voltage to completely recharge in as little as 30 minutes. These
unusual properties make selecting and configuring the solar panels,
inverter and charge controller quite different from other batteries. We
work with each and every customer to make sure that the components are
harmonized to ensure optimum performance.
Our prices listed with actual tested performance
One universal truth: All batteries produce more total output
when discharged more slowly, e.g., with less power being drawn. Another
truth that applies to all batteries: The per-cell performance of a
battery--made up of a number of cells--is always lower than the
performance of one single cell. With this in mind, consider these
factors when comparing.
Other battery companies run a single cell at the (low) power
level required to finish discharging at 100 hours. This is not
representative. First, discharging 1 cell for 100 hours will produce
more PER CELL than discharging 10 cells for 100 hours. Second, no one
cares how much power is available as a result of discharging for over
four days (over 96 hours).
Keep in mind that, after a complete discharge, a lead-acid battery used for such a test is pretty much destroyed.
Our approach: We provide representative data. Rather than
using a single cell, and then unrealistically multiplying by the number
of cells in a battery cell, we offer test results for a 10-cell
battery. And we don't offer test results beyond 58 hours.
Also, keep in mind the time to charge lead acid vs. Zapp Works batteries. Per Battery University,
lead acid charge time is 12–16 hours and up to 36–48 hours for large
stationary batteries. Compare that to as little as 30 minutes for Zapp
Works.

Maintenance and Warranty
During Zapp Star Battery installation, we
add a 1/4" layer of consumable grade mineral into the electrolyte. All
you need do is keep the water level between the two level lines by
adding distilled water. Provided you perform this maintenance, a
two-year warranty is provided.
Zapp Works proudly offers Made in Montana Nickel-Iron batteries.
Lifetime batteries from the USA.
