Was finally able to finish the job that I have started before new year.
I was changing the charge wiring to 1/0 AWG, but had to wait for the surepower relay. Mine was recalled and took a long time to get a new one. I asked them for an upgrade while changing it in and got it 4 free.
🙂Previously I had a 1315-100amp, but changed that to 131
4-
200amp, wich was much better with the 1/0 wiring and to uni-directional for solar. The recall came at the right time.
😉By the time it got here, the truck was gone for a transmission rebuild. I got it back Wednesday.
So yesterday I placed the 1314-200amp relay and connected it, placed and connected my 200A shunt and A-meter, connected the "emergency start" switch, the "emergency cut-off" switch and two led-lights.
Then I placed our extra battery in a hiddenpower from Torklift. We now have a total of 315AH from 3 trojan 27TMX batteries.
When all this was done, I tested my two-way-usage-with-a-one-way-battery-separator-theory. (omg) And it worked!
🙂 The reason is: I only want one-way charging, because I don't want to loose solar power to charge the truck batteries. When I'm on shore power, I can choose to charge the truck batteries anyway by using my theory. In other words, I can use it semi-automatic bi-directional if I choose so.
The theory was to hold the emergency start switch for some time (which seems to be 12 seconds) and then release it. After this time, the one-way separator stays closed because it sees more than 13.2V at the truck side. I saw 5 to 10 amps of charging current going from camper to truck, so this is the amount that would get lost by solar if I kept the bi-directional separator.
Some pictures:
The ammeter works as soon as the separator makes a connection, so I can see when the batteries are charging and by how much. "Plus" means that the truck alternator is charging the camper batteries. "Minus" means that the camper is charging the truck, which is the case in the pictures.
And now I'm going outside to dewinterize and install a water saving shower head.
Greets!
