Iota IQ-Turbo Rapid Charge Controller DLS Battery Chargers

Easy to install and works great.

So much easier than manually switching charger from fast to slow. Presumably better for the batteries, too. Needs Bluetooth interface to a monitoring app.

Update: This controller is fine for on-grid use but off-grid means you’re using it with a generator and this controller is not so great for that. To reduce generator run times I prefer to use their Equalizing controller and I have it paired with their 55A charger to a 460AH battery bank. The charge profiles are shown below for the two controllers. The Turbo controller amps start tapering off around 14.3v and that happens within 10 minutes. After that it’s only delivering about 35amps. The Equalizing controller amps taper off starting at around 15.1v after about 25min. After that it’s still producing 41amps. This is entirely due to the batteries acceptance rates at different voltages but he upshot is that you charge much harder with the equalizing controller and that reduces generator run time. Keep your batteries watered and don’t exceed the battery specified charge rate (mine are 10% of the c/20 rate or 46amps) - I do exceed that but not for long and not by much.original:I contacted Iota for the spec on this and the Equalizing module. The output voltages are:This unit (turbo):14.78 volts for 4 hours, then14.51 volts for 2 hours, then13.6 voltsIQ-Equalize unit15.4 volts for 2 hours, then13.6 volts for 160 hours
