Status: Sheltering in place, we have plenty of food and supplies. We are still higher than the peak when the Governor gave the sheltering in place order.
Plans:
- 08:00 Up, eating breakfast and making plans for church.
- 12:00 Nap time.
- 14:00 Up getting organized.
Narrative: Testing the first of two 35AH batteries removed from the 48V string yesterday using about 40W load. I started out with 7W and increased it looking for the battery to falter. When I got to an hour at 28W I plucked a 40W light bulb out of the closet and used that instead of the four candle lights. I also have a 60W light if I get that far with the battery.
The first of the two only got 7AH out of it before the inverter called it at 10V. The second was 11AH and running at 11V when I pulled it. The charge has been 3.5A (1C) and it is still charging this morning at 7Ah+. I expect the internal resistance to increase as the battery is discharged, however the resistance is a little high to me for a 35AH battery. (I think the 18AH batteries I have were much lower.) The voltage of this second battery discharged below 70% jumped to 14.2V at 3.5 A charge, which I thought was not very good. These batteries seem way too “Mushy” to me for a UPS, meaning the internal resistance is pretty high. (Maybe a couple of ohms.)
Thinking of doing a test at 1C which is 3.5 Amps on all three strings. 3.5x50V is 175W, these UPS units are good for 1200W which is 24Amps. (Almost 7C) Maybe a better test in my case would be 350W or 2C, the batteries should last about 4 hours at that rate.
I have started to build the cables to connect mom’s solar panels to the golf cart. Normally waterproof MC4 connectors would be used but since this would be a temporary setup and mom would have a hard time connecting / disconnecting them I am transitioning to red Anderson SB50 connectors.
Feelings: Police are on such difficult ground, their jobs are impossible and there is a camera everywhere to find fault in their decisions made at gunpoint.
