About this diagram
Use the sunshine. Store the surplus.
Solar powers your home and charges the battery with surplus energy, reducing daytime grid purchases.
Illustrative scenarios. Actual supply, backup and savings depend on equipment, settings and available energy.
Common questions
Can I use solar energy after sunset?
Yes, if it was stored in the battery during the day. Stored solar energy can reduce evening grid purchases until the battery reaches its reserve or its power limit.
What happens during a power cut?
For Caribbean homes planning around outages, a correctly configured backup system can isolate from the grid and supply selected essentials using available solar and battery energy. Runtime depends on charge and loads; an empty battery and insufficient sunlight cannot sustain backup. Supply fluctuations and sensitive appliances should be discussed during the site assessment.
Can solar and the grid power my home together?
In a compatible hybrid system, solar can supply part of your demand and the grid can cover the shortfall. This still reduces grid purchases. Our example keeps the battery in reserve; actual sharing depends on settings and available energy.
Can the battery help when solar is not enough?
Yes, while usable charge and power are available. Solar and the battery can supply your home together, reducing grid demand. The grid may also contribute if supported by the configuration; this does not remove the system’s power limits.
