solar-battery-backup-626x626Perhaps your solar installer had suggested you add battery backup to your solar energy, and you are confused about the same. Let’s sort out your confusion by discussing four essential aspects related to it. Here we will focus on AC coupling approach that lets a user store energy that can be used during emergencies and outages.

Elements of an AC-coupled system

The major elements include:

  • An energy storage system having batteries and an enclosure
  • A grid/hybrid inverter or charger
  • A center or a coupling device
  • Additional electrical wiring

Importance of AC-coupling

This approach is valuable for every party involved, including the end users, solar installers, and distributors, thereby creating a win-win situation

Factors to look for while choosing the equipment

Make sure the inverter you choose operates effectively with different brands of string inverters. Try to get an inverter with split-phase design and generator input and protection.

The cost of AC-coupling

The average cost of AC-coupling is approximately 16,000 dollars, whereas the electronics-only package cost you around 8,600 dollars.
