outback solar mppt controller
anyone had any experience with the outback mppt controllers? I see solar blvd has a 10A for $99 and a 20A for $149. the 20 A would be a nice update from the morningstar 15A at a reasonable price...

You've maxed it up at 24V battery bank. If you go 48V, you can double your solar wattage without buying another controller.
SMK is right, this controller is not too automated when it comes to absorption.
I wonder if my Rogue 30 is the only MPPT with automatically adjusted Abs time. It terminates Abs stage when current drops to preset (adjustable) value. And, if it doesn't drop, then preset Abs timer (also adjustable) kicks in. In storage it's keeping Abs time very short, some seconds, as the current drops quickly after it hits Abs voltage. I already hear all the flooded crowd screaming - "Heresy! Keep'em jars boiling!" - well, mine are not flooded. I don't think they need much boiling in storage, either.
