What are the disadvantages of battery back-up systems (Hybrid)?
Hybrid systems typically require a larger up-front investment than grid-tie systems. Batteries are an additional expense, require maintenance, only last 5-10 years, decrease system efficiency and result in a more complicated system. Many of our customers opt for a grid-tie system and purchase a standby generator with a properly installed manual transfer switch. For a given level of power output, generators are usually the least expensive option for backup power production. Generators provide the most reliable and cost effective source of extended backup power, eliminate the additional expenses related to batteries, and have backup power available for as long as they have fuel.
