Have a happy Thanksgiving
@vitalssigns - and everyone, (Canadian T-G was back in October, home grown Turkey was so good). lol.
When you are ready this is my recommendation for initial testing:
Small steps approach:
Step one - disconnect everything from both inverters. EVERYTHING - remove the PV supply all wires from both inverters, switch off both.
Step two - disconnect all the server rack battery cables and switch them all off.
Step three - with nothing connected, turn on one rack battery - the top one. put a meter and see if you have 50-54 volts (like you did back at post #78 where you have the meter red to red, black to black on the top battery - it was showing proper voltage. Lets confirm it still does.
Step four - connect the neg from the top battery only to the neg of
one inverter. Then connect a cable to the pos of the top battery.
Step five - Now attach one light bulb wire to this pos cable.
Step six - touch the other light bulb wire to the neg battery terminal for a few seconds - the light should come on dim, and stay dim.
Step seven - now touch that same light bulb wire to the pos terminal on the inverter for a few seconds. - the light should come on dim and fade out.
STOP HERE - report to the forum the follwing:
Did the light bulb glow dim when you touched the bulb wire to the battery neg terminal at step six. Yes or NO?
If YES - did the light bulb glow dim when you touched the wire to the inverter positive terminal in step seven. YES or NO?
If YES - did the light bulb glow dim and fade slowly or did it glow dim and stay steady dim, STEADY OR FADED?
We will move to the next steps once we have your replies to the above.
Gobble - gobble!
