Should you buy an Alpha ESS solar battery?

On a cost per kilowatt-hour (kWh) basis, the Alpha ESS solar battery range has made adopting a lithium battery system a far more viable concept than previously conceived. With such improved economic viability, the obvious question arises; is the Alpha ESS the ideal solar battery for you?

Pros & cons

When it comes to solar battery systems, you are one of two shoppers. An existing solar owner wanting to store excess solar energy (instead of exporting to the grid) or a new solar purchaser weighing up the viability of the ultimate energy solution; solar power infused with energy storage for 360° energy savings.

Either way, some vital questions must be answered to validate your energy investment, even if such presents an economically viable solution. Could the Alpha ESS solar battery range be the energy solution you’ve been searching for?

There’s an interesting commonality within the Alpha residential solar battery range. They’re all smiling. The obvious question arises, what does SMILE refer to? 

Potentially your face when the next electricity bill comes in after installation? Perhaps it’s what you’ll be doing during your first blackout when you have power and the remainder of the street doesn’t. 

Both are likely instances to smile. However, creatives behind Alpha ESS branding have constructed the acronym as follows;

  • Self-sufficient
  • Modular battery
  • Intelligent control
  • Long lifespan
  • Elegant design
