Thanks. So the suggestion here is that I just connect the large AGM storage battery and the smaller UTV FLA to the output of the charge controller and set the controller for AGM? This seems dead simple and ultimately I would replace the UTV battery with a no-maintenance AGM anyway. A 10 Amp...

Morningstar looks to be top notch, but pricey. I am not a big fan of Renogy's documentation or customer support, but the Adventurer is a flush mount (like my existing) and the current model does appear to allow selecting what bulk/absorption voltage to use. The BlueSky SC30 ($100) appears to...

I finally have the BlueSky SC30 installed. I had to slightly enlarge the hole in the panel where the Go Power SCC was. While I had the saw out, I added a DC breaker so that I could disconnect the PV + input when necessary. The unit is very easy to program and all parameters are available...

Thanks. I checked out the Optimate at your suggestion. At $110, it's more expensive than the simple solution suggested by Vigo, but it seems like it might be easier on my UTV starting FLA in the long run. In the attached diagram, I could replace the Optimate with a separate 10A PWM controller...

I have been thinking about replacing the SurePower 1314-200 battery separator in my 2016 PleasureWay Lexor class B with a DC-DC charger, so this thread is right on the money. The RV came with 2 proprietary (EcoIon) 100 Ah LiFeP04 batteries with built-in BMS and 3 95 watt 12V solar panels going...

I have a shed I have on a remote property in Michigan with a 50 watt panel feeding a 40Ah LiFePO4 battery for lighting and occasional inverter use. I've already set up a thermostatic switch that kills the PV feed to the SCC when the battery case gets close to freezing and everything seems to...

I thought about that, but a "reverse" photo switch that closes during daylight hours is what I need and hard to find. I'd rather not waste the electrons at night when the battery won't be charging anyway. The idea is to warm the battery as necessary during daylight hours when the solar panel...

I'd like to set up my 12x16 garage/shed with a single 50W solar panel that will both charge a storage battery and keep the FLA battery in my Polaris Ranger topped off. The storage battery (I am thinking 50-100 Ah AGM) will be for 12V lighting and occasional 800W inverter needs. This will be...

That's helpful. In my case, the battery is more than capable of getting us through the night and solar is only supplemental, so no float would be OK. The only option on my older GP SCC is a 13.7 float which is 0.4-0.5 volts than the no-load voltage of my fully charged LFPs . Interestingly...

Agree with you that "if it ain't broke, don't fix it", which is why this has been down on my list of things to do. Part of this is trying to better understand how all these systems in the RV work. My model year was the first that Pleasureway went from AGM to LFP. In 2016, LiFePO4 in RVs was...

I would hate to replace one PWM with another unless it's to make it easier on my batteries. One of my hold-ups in going to MPPT is that the 3 parallel panels on my roof are also older and relatively low voltage (Vmp 17.5). Since an MPPT requires that the panels be at least several volts higher...

It's an excellent point. The RV lives in a barn when we're not using it. When we are using it, we're charging with the alternator (though a DC-DC charger - one of my first improvements) and solar or plugged into shore power. Occasionally we boondock but only for a few days at a time (my wife...

After reading the Blue Sky SC30 manual, I liked it so much that I ordered one. It should fit right into the existing cabinet cutout. One nice thing is that they don't have fixed profiles for different battery types, but rather allow for the user to select values for every parameter. Not a big...

Your replies put my mind at ease, thank you. Unfortunately, there is no option to define charging profiles on the existing SCC. From what I have read here and elsewhere, I understand why LiFePO4 should be charged with a fixed bulk/absorption voltage 14.2 +/-, but the opinion seems split on...

I'd guess that there are good and poor hall sensors and shunts. For me, any possible lower accuracy of the hall effect sensor is offset by the easier siting and installation. I use these in front of and behind my DC-DC charger and at the starter battery and really just use them to make sure...

I am stepping through upgrades on my 2016 Pleasureway Lexor TS class B and have come to the solar charging system. The RV came with two 100 Ah LiFePO4 batteries, three 95 watt roof panels and a GoPower 30 Amp PWM SCC without a LFP charging profile. The manufacturer says to use the AGM...
