EXPANDABLE
SOL STACK batteries are expandable in 105aH increments (2.4kWh @ 24v, 4.8kWh @ 48v).  Buy the capacity you think you'll need.  Upgrade affordably if it's not quite enough.
RE-STACK FOR DIFFERENT VOLTAGE
Easily upgrade a 24v battery to a 48v (or 48v to 72v) by simply re-stacking and adding modules as necessary.  FUTURE PROOF BATTERY!
LOCAL, ON-SITE, 10 YEAR WARRANTY!
Manufactured locally, with on-site service island wide!  10 year warranty with no hassles.  We come to you for service and repairs.
MASSIVE POSSIBILITIES!
A single SOL STACK battery pack can go up to 30kWh, with 250amp current capacity.  Build massive battery installs with little space.
PREMIUM PRISMATIC GRADE A CELLS
Prismatic cells perform better, and have longer life for solar energy storage than the cheap cylindrical cells used in most lithium packs on the market.
EASY 1 PERSON INSTALL
SOL STACK batteries are comprised of lightweight modules which can easily be installed/assembled by 1 person.

EXPENSIVE TO EXPAND
Your only option is to add another complete battery with the similar capacity.  Bought 10kWh but need 12kWh?  You'll need to add another expensive 10kWh battery to get that additional 2kWh!
CANNOT CHANGE VOLTAGE!
As inverter technology advances, voltages keep going up.  With typical battery packs, you will have to buy a new battery to upgrade your system voltage.
IS THAT WARRANTY WORTH ANYTHING?
If you have to ship your battery back to the US or even China for service, or the warranty is pro-rated...you may find the warranty is basically worthless here in Puerto Rico.
LIMITED OPTIONS FOR LARGE BATTERIES
With typical battery packs, you may have to install several to get to the capacity you need.  This means more space, more expense and more points of failure.
OFTEN CHEAP CELLS
Many "white label" batteries being sold in PR today use cheap cylindrical, or even grade B cells.  These do not perform as well and do not last as long.
HEAVY PACKS, DIFFICULT TO INSTALL
Lithium packs can be quite heavy, making them difficult to wall mount, requiring 2 or more people to install.
