Comment NOT Why I Have a Backup Battery (Score 1, Informative) 104
How do I block Southern California Edison (SoCalEd) from draining our backup battery? I had the battery installed because of health reasons.
My wife has COPD and Parkinson's. She needs electricity 24/7 to run an oxygen concentrator. She needs electricity to run the stair-lift in our two-story house. I have sleep apnea. I need electricity at night to run the CPAP machine that keeps me breathing.
During a public safety power shutoff (PSPS) earlier this year, we were without electricity from SoCalEd for more than a day. In the daytime, we had electricity from our solar system; in the night, we had electricity from our battery. The PSPS did not impair our health.
Actually, a PSPS is not my only concern. SoCalEd fails in my area without warning, without regard for the weather, at any time of the year. Sometimes, it is only for a few minutes; sometimes it is for many hours. If it happens while we are sleeping, we might not realize that we must report the outage. With our battery, we are protected.
