Fortress Battery Backup for Solar Why do we Recommend Them in our Installs?

Innovation is key in the solar industry. If you are looking for an innovative battery backup for solar, then you need to consider a Fortress Power Battery. The Fortress Power Lithium Ferrite Phosphate (LFP) battery bank is the latest addition to the wide array of innovative solar energy equipment that we offer at Belmont Solar.

Why is a Fortress Power Battery a Better Battery Backup for Solar?

Battery banks for off-grid and hybrid systems are not new, but the type of battery backup you choose impacts the overall efficiency of your solar system.

This Fortress Power battery bank improves efficiency via storage capacity and power output, and is safer for off-grid and hybrid systems.

Let’s break this down even further. Here are a few specific reasons why we love this Fortress Power battery:

  • LFP batteries will not explode or catch fire because they use stable chemical compounds.
  • When compared to lead-acid batteries and gas-generators, the LFP battery bank doesn’t expose your family or the environment to harmful gases or chemicals.
  • LFP batteries have been proven to be longer lasting and greener than lead-acid batteries without sacrificing power or reliability.
  • LFP batteries grant a 100% depth of discharge, whereas lead-acid batteries only offer a 50% depth of discharge.
  • LFP batteries cost less per cycle.
  • LFP battery banks will give you more reliable power that is less wasteful and less harmful to the environment than lead-acid batteries.

Plus, it’s a nice-looking battery backup for solar!

Obviously aesthetics aren’t everything, but we do really like the look of this Fortress Power battery! It has a clean-looking white metal case and looks good even when installed on a wall. In addition to that, this Fortress Power battery has a sleek, compact design that makes it flexible and easy to install. If you want the battery backup to be floor-standing or wall-mounted, you can rest assured that this compact design will be just what you need.

What Types of Solar Systems will use a Fortress Power Battery?

Traditionally, batteries and battery banks are a secondary amenity for solar power systems. This is largely because most solar power installations are grid-tied systems, where having a battery backup isn’t necessary.

However, a Fortress Power battery backup will enter the discussion when we look at off-grid and hybrid solar systems. Let’s do a quick overview of these two types of solar systems:

Off-Grid Solar System

With an off-grid solar system, a solar panel array collects energy from the sun and converts that energy to consumable power for your appliances (AC current). During the day, your appliances will run off of this AC current, and any excess power will be used to charge the Fortress Power Battery. When the sun is no longer supplying energy (during nighttime or a storm), your charged Fortress Power battery bank will take over and continue to supply your home and appliances with power.

Hybrid Solar System

A hybrid solar system (commonly referred to as grid-tied solar with battery backup) performs a little differently. Like the off-grid system, the solar panel array collects energy from the sun and converts that energy to consumable power for your appliances (AC current). Again, the excess power is then used to charge the Fortress Power battery bank.

However, here is where the difference lies. Any excess power not being consumed or stored in the battery bank gets directed back onto your local grid. This has the potential to offset your cost of consumed grid power that your system will rely upon when the solar panel array is not collecting sunlight. Furthermore, if the grid fails, your Fortress Power battery bank can continue to supply your appliances with power from its charged cells.
