SOL STACK IS EXPANDABLE
Need to add capacity? With SOL STACK adding capacity is easy with CapacityPacks.
With the competition? Not so much. Add a whole new battery...
UPGRADING VOLTAGE
Have a 24 volt system now? With SOL STACK you can simply "re-stack" your battery modules to 48v in the future. Soon 72 volt systems will be common. Buy a SOL STACK and you can upgrade easily.
BETTER QUALITY CELLS
SOL STACK uses only Grade A matched PRISMATIC cells from EVE (one of the best battery cell manufacturers on the planet). EVE cells are rated for 6,000+ cycles, with a reputation for living up to that rating.
Many other manufacturers use cheaper cylindrical cells (lower performance), and even less reliable Grade B cells.
10 YEAR WARRANTY WITH LOCAL SERVICE
A REAL 10 Year Warranty, with local service island-wide within 3 days.
With other batteries you may find that there is no viable warranty, or you have to pay expensive shipping to return the battery to the manufacturer for service or replacement - and wait without power while they honor their warranty.
EASY 1 PERSON INSTALL
SOL STACK batteries are assembled from lightweight 12v modules (20-40 lbs each), so 1 person can easily wall mount a SOL STACK.
Other batteries are heavy, and can be difficult to wall mount - even with 2 able bodied people.
BIGGER BATTERIES AVAILABLE
With SOL STACK a single 48v battery pack can be configured up to 42kWh. SOL STACK takes less space for large installations, and results in a visually cleaner result.
MANUFACTURED AND STOCKED IN PUERTO RICO
All SOL STACK batteries are manufactured in Puerto Rico, for Puerto Rico. Our stock is local, and does not require waiting for your order to ship in from the US or elsewhere.
