Best Solar Battery Backup System for Home in Canada 2024

Best Solar Battery Backup System for Home in Canada 2024

Solar power has gained significant traction among Canadian homeowners, prioritizing sustainable and dependable energy solutions. The solar battery backup system is integral to a comprehensive solar energy setup. This innovation empowers homeowners to accumulate surplus energy generated by their solar panels, facilitating energy autonomy and guaranteeing uninterrupted power supply, even in the face of outages. In this guide, we'll explore the best solar battery backup systems for homes in Canada in 2024, helping you make an informed choice for your energy needs.

What Is the Solar Battery?

A solar or residential energy storage battery is a mechanism for retaining surplus electricity solar panels produce. This electrical energy is preserved in chemical formats, predominantly lithium-ion or lithium iron phosphate, to be tapped into when solar radiation is unavailable. Solar batteries are available in diverse dimensions and capabilities, and your selection should align with your specific energy requirements and personal inclinations.

Battery Capacity and Size

Battery capacity, usually denoted in kilowatt-hours, represents a battery's overall energy storage capability. It's crucial to acknowledge that the practical capacity of a battery may not align with its full capacity. Typically, the usable capacity of a battery is restricted to around eighty percent to ninety percent of its total capacity. This limitation is in place to extend the battery's operational life and prevent potential issues at extremely low charge levels. To illustrate, a lithium battery boasting a total capacity of 10kWh might have its usable capacity capped at eighty percent, facilitating a daily discharge of 8kWh. Nonetheless, depending on the system's configuration, the remaining ten percent to twenty percent can often be accessible in critical situations, such as extended power outages.

Determining the appropriate battery size is a fundamental factor to contemplate when selecting a solar battery. It involves determining the right battery size to meet your energy needs. A 'too' diminutive battery might not deliver ample power, whereas an excessively large one might not acquire an adequate charge, especially during winter. To circumvent these predicaments, it is crucial to opt for a battery and determine its dimensions based on multiple considerations:

  • Solar Array Magnitude: Whether you possess an existing solar array or contemplate installing a new one, the magnitude of your solar system influences the quantity of energy accessible for storage.
  • System Classification: Make the determination of whether your solar system is on-grid (interconnected with the utility grid), off-grid (independent), or a hybrid system (merging both on-grid and off-grid functionalities).
  • Backup Power Requirements: Consider how much backup power you need during outages or low solar generation.
  • Evening or Overnight Energy Consumption: Understand your energy consumption during the evening or overnight hours, which will determine the battery size needed to meet these needs.

Modern battery systems are often modular and scalable, allowing for flexibility in sizing to match your specific requirements.
