Home Solar Backup Power Supply Systems – Backup Batteries


Backup battery systems or generators keep the power on for safety during outages, preventing productivity losses, avoiding perishable food waste, and eliminating costly repairs like frozen pipes and flooded rooms. Backup power systems can also make it possible to use the solar energy you produce outside of daylight hours to power your home or electric car.

What is Backup Power?

Backup Power is a system that connects to electricity sources, typically solar panels and the electric grid, to store excess power and return it to your home when you need it, generally because of a power outage during an emergency. In most cases, your backup power supply will come from a generator or a battery. Today’s solar batteries are also intelligent energy management systems that can optimize your home’s energy usage to take advantage of utility time-of-use plans or to ensure that your electric car is charged with your solar power system.

Tesla Powerwall Battery

Tesla Powerwall

The Tesla Powerwall is a home battery that works by intelligently storing energy during times when energy rates are lower, and using this less expensive stored energy when energy prices start to rise.

This solar panel battery solution is ideal for those looking to save money by switching to solar energy during times when home utility rates are high.

The stored energy can also be used in an emergency situation as a home battery backup for electricity supply. Tesla’s battery backup system offers 13.5 kWh of energy storage capacity, enough to power an average home’s lights, refrigerator, and small appliances for (but not A/C) for one day during a power outage.
