rjxj - Using a Dremel to cut the screw head off is a good idea. Thanks for the better link to the datasheet for the RSP-320-15. As you said, scroll down to page two.
Almot - I want to use a 100 amp charger when off grid and using a generator to charge the batteries from 50% to 80% quickly to reduce the generator run time. After many 50% to 80% charges and later at a campground (on grid), I will Top Charge to 15.0V to remove any sulfate build-up from the previous under charges (50-80). I got this method from Mexicowanderer, I hope I understand it right.
landyacht318 - "Also, it does not have constant current limiting on overload, so if the batteries were discharged enough to draw more than the Meanwell could provide, it would shut off until overload was removed, making it more useless for battery charging."
I was wondering if the Overload Protection mode (and more) was suitable for charging. Still I wonder if the batteries were fully charged by the converter, then charged with the RSP-320-15, if it wouldn't go into overload and shut down. I'll look for another model with constant current limiting. I want to have output of about 20-24 amps (4-6% of battery capacity) to fit Mexicowanderer's formula for Top Charging.
westend - "It sounds like you have lost one leg of the 50 amp service."
That's what I think. I put a meter on the end of the power cord and got 120V on L1 and L2. The power cord connects to a Marinco socket on the side wall, and from there the cord goes to the circuit breaker box. Since the problem appeared immediately after turning the main breakers off and on, I suspect the right side 50A main breaker.
Thanks for the tips on getting the screw off.
CA Traveler - Thanks for the tip on a screw extractor. I depends on the shape of the broker nut flange. Pulling out while turning might lock the nut flange in place.
Thank you all the the help. Please keep them coming!
