- 10:00 Cleaning.
- 11:00 Moved Backup CKT to a Standby Modified Square wave UPS to reduce heat.
- 12:00 Shut down Pure Sine Wave inverter. (Reduced the noise considerably)
- 13:00 Cleaned up materials used in testing the batteries for MSW Inverter test.
- 14:00 Built cart for groceries tomorrow. (Now very complicated with Dental APT.)
- 15:00 Nap

Narrative: Shortly after we bought the house I had a homebuilt Un-Interruptible Power Supply that powered my computers and the lights on the fireplace. Over the years it has become a secondary breaker panel with outlets in every room that will remain powered when the utility power fails. It also has become two completely redundant circuits with separate power sources that can support their loads for more than five and up to twelve hours. (Including a third circuit for the refrigerator.)
Today I have stepped backwards on one of the two circuits, I have decommissioned the “Online” UPS for an offline modified square wave one. (That I used to use about 10 years ago.) The advantage is they don’t produce any noise and very little heat. The disadvantage is that they tie the utility power to the house circuit as long as it falls within an acceptable range. Outside that range a relay switches the power to battery with a minor break in power to and from battery. (The online UPS use battery power for their inverters 100% of the time so there is no break in power.) There is a significant power loss with the “Online” UPS units of about 20% where the offline ones are near 100% efficient when they are not charging the batteries. The last problem that the “Offline” versions have they don’t recognize a MSW as an acceptable power source and will run on battery. I found out that my new 48V online UPS units are also in that category, which was unnerving.
I’ve already moved most of my loads off of the online UPS in the garage to reduce the temperature extremes that are not good for my batteries.
White Fragility: I really wish that the national news would not carry EVERY SINGLE incident of abuse to a black man without giving an equivalent amount of media attention to all colors of men and women that have been abused. It paints a very biased picture that black men are always the target of abuse.
