Hello Peter,
The 3024iL and DiL have a few parameters that can be programmed with the internal DIP switches. Switch 7 will allow you to change the acceptance time. This will help lengthen the charge time as long as the current draw stays above the factory default setting of 1.5 amps/100AH capacity. You are correct: You must have the IPN Pro to adjust the float transition current to force the controller to stay in acceptance long enough to charge AGM's properly. You can program down as low as 0.1% of the 100AH capacity. The IPN Pro can be used to program all the settings of all IPN controllers and dealer cost is much less than a "few hundred" dollars.

Dan et al,Thanks for all the input. The 1 mA per A-hr capacity (20 hr) for AGMS was very important to know. Our AGMs are 250 A-hr, so that equates to 0.25 A. This is exactly what we are getting right now in float mode.The problem that I was having arose from the Blue Sky 3024 DiL CC only staying in acceptance mode for 2 hours each day (this is the factory default). So it took quite a few days to really top off the battery bank.In order to program the scenario I want, I will have shell out a few hundred bucks for an “IPN-ProRemote” to access and adjust the acceptance mode parameters on the 3024.- PeterPeter T.
