A while back I installed two 125 watt solar panels, but I was never happy with the power controller I installed.

In part this was because I installed 18 volt panels for a 12 volt battery system, and at the time the options were limited. Today the situation and the electronics are better. At the time there was more choice if I had gone with 24 volt panels, but those panels are quite large.

Blue Sky Energy’s 3024i fills the bill nicely.

Solar Boost 3024i provides an advanced fully automatic 3-stage charge control system to ensure the battery is properly and fully charged, resulting in enhanced battery
performance with less maintenance. An automatic or manual equalize function is also provided to periodically condition flooded lead-acid batteries.
