the only time an OB GFX bulk charges is after a grid outage.

I’ve had some success with RE batteries in float service by reducing the absorb time and float voltage. Talk to the manufacturer for their recommendation.
 
I think float service is fine for RE batteries, but bulk charging every day when the sun comes up just cooks them unnecessarily. Also anecdotal…

I would not recommend using an RE battery for standby/back up use.

 

There is a similar problem that I have seen. People use 6 volt golf cart batteries in their motorthome and then stay plugged into shore power for long periods of time. I see premature failures from this type of use. A golf cart battery is designed to be cycled, not left in float service. Without exercising the battery by occasionally discharging it and then charging and equalizing, it is likely to fail early. My opinion is anecdotal but I'm convinced it is true.

so what does this mean for grid ties/battery back-up?
