Hybrid systems
Store solar energy and keep your essential appliances running during outages too.
LA Solar designs hybrid systems for homes and businesses based on consumption, the selected appliances and the required run time.
How a hybrid system works
During the day, the energy produced by the solar panels is used first for current consumption.
The surplus can be stored for later use or exported to the power grid.
When solar production is not enough, the system uses the stored energy or the power grid.
A hybrid system is most effective under the current offset scheme (Net Billing), because it lets you use stored energy in the evening and at night, reducing the electricity you buy from the grid.
During a power outage, the pre-selected backup circuits and appliances are powered from the battery.
When to choose a hybrid system
A hybrid system is the right choice if:
A battery does not run every appliance indefinitely. The required capacity is calculated from the power of the selected appliances and how long they need to run.
What can run during an outage
For homes
- essential lighting
- refrigerator
- internet and communication devices
- security system
- heating control system
- water pump
- TV or computer
- other priority household appliances
For business
- computers and servers
- point-of-sale systems
- security and CCTV systems
- refrigeration equipment
- communication and internet systems
- priority production equipment
- pumps or control systems
Actual capability depends on appliance power, simultaneous use and battery capacity.
How the battery capacity is chosen
Battery capacity is not determined by the solar system size alone.
For example, a 10 kW solar system can be paired with a 5–20 kWh battery bank depending on which appliances must run and for how long. The final capacity is determined by an individual consumption calculation.
- •total power of the backed-up appliances
- •start-up loads of the appliances
- •simultaneous use
- •desired runtime
- •usable battery capacity
- •possible system energy losses
- •the need to expand the system later
