Haha, we would not have the pool heater on a backup system, but many times people want a partial home backup system with whole home annual grid offset.
But for practical purposes around here, full-time residents often just trade pool heating for air conditioning based on season. If you size a backup system for central air conditioning, sometimes it is technically possible to heat the pool off-grid in the winter because the house load is otherwise a fraction of what it is in the summer months. In the winter, we sometimes see batteries full by 9:00 am and a lot of wasted solar energy.
