Status: Sheltering in place, we have plenty of food and supplies.
Plans: Put away groceries and take a walk.
- 07:00 Get up, have coffee, read the paper.
- Changed out portable battery connectors from Red/Blk to Pnk/Blu.
- Change UPS connector from Pur/Blk to Pur/Blu.
- Labeled all ten portable 20AH Deep cycle battery packs.
- Installed Red/Blk connectors on new DC power meters.
- Checked bathroom sink drain.
- Dishcharge test on two portable batteries (2 Yrs Old)
- 10:00 Walked around the block
- Attempted to run Inverter on Club Car charging port, OBC disconnected it.
- Left a message with Golf Car service center to get an SB-50 pigtail installed.
Narrative: All that tests that I’ve done with the 48V Inverter have gone very well. Other than just being HUGE, it’s very efficient and continues to run without fault.
In the homestead I have three prominent voltages, maybe four. When I built the 56V battery bank and accidently connected it to the 28V bus destroying a 12V regulator, I knew that I needed to color code the voltage on the wires. The first is a regulated 12V (Red/Black), then I also have a battery voltage of 14.2 (Pink/Blue). There’s 24VDC Orange/Black also unregulated battery voltage 28V (Orange/Blue). For the 56V unregulated voltage for the UPS I’m using (Purple/Blue), I don’t have a regulated 48 volts anywhere (Purple/Black). Two solar panels in series is Yellow/Black. AC voltages are Grey/Grey.
If you were wondering how I came up with that color code it was a long road. When I decided to run a DC line to every room in 2012 I was thinking low power with solar backup. (CPAP and emergency lighting.) I bought two 500′ rolls of Red/Black wire and ran them across the attic to every room from the garage. At that time I only figured on using 12V, so the connectors on the homestead were red/black just like the wires. The NEC by the way says that Black is a “HOT’ wire above ground and that I should have used a “White” wire instead. The plan is to run a white wire in addition to the Red/Black ones to satisfy the requirement. (+12 Red, Return White, -12 Black ) which supports all the requirements of the homestead with those three colors. (I don’t foresee running 56V across the house.)
The CPAP didn’t like the voltage drop at 6A @ 12V so I needed to push 24V for that purpose which used the same Red/Black wires. Very little in the homestead cared whether it was 12V or 24V so it didn’t matter the wires stayed the same color. When I added the solar panels I really needed to separate the 42V from the DC distribution and the color code was started with Yellow/Black. I had to buy a significant amount of connectors to interconnect the batteries and power distribution. Pink/Blue arose out of having 14.2V portable battery banks that needed a separate charging circuit. The homestead had a pair of power supplies that used the 14.2V (Pink/Blue) and regulated it down to 12V (Red/Black) It also has a pair of power supplies that regulate the 28.2V (Orange/Blue) down to 24V (Orange/Black) When I bought the 1500VA 56V UPS units I needed a third color which became purple/blue. (Blue being battery at this point and black being a regulated return.)
