Still having b attery problems

Good rant!!!

What all my "rantings" boil down to in your specific case.. and if you are not comfortable delving into the miriad of custom settings (very understandable)... I think you would find that moving to the AGM-2 profile would make you a much happier camper with shorter charge times and minimal impact to your battery banks lifecycles.

If you want to stay with equalization cycles, you could select "flooded" and be still be well within the tolerance ranges of your AGM's.

Option #3... back to AGM 1.

We have diligently followed Magnum's settings and had everything set for AGM 2. We were aware that settings were different for AGM batteries and felt Magnum should know what they are doing. I think our biggest problem was looking at voltage(since everything seems to use voltage as the "standard") and that threw us into a panic. As we learned from all of you and upgraded our monitor we felt more and more comfortable that all was really fine.

At this point we will stick with AGM 2 and no equalization. If we start seeing lower rating problems we will probably equalize.

We are working on getting our 2nd solar panel, just waiting for an appt. time and then we should be in good shape. The supplier is holding a panel for us.

That's entirely my bad then. I had, mistakenly, read that you were using the AGM 1 profile. Sorry...

You're good.

I'm not sure if i should jump in with some unsolicited advice about the solar panels and wiring or not, but here it goes anyways.

Just in case you haven't thought about the these things:

--  Be sure the new solar panel matches the old panel in watts and voltage. 

--  Check the wire size coming down from the solar panels (or combiner box).  If the wire size is #10 and the solar panels will be wired in parallel, you may have a significant voltage loss (more than 3% loss) when the solar panels are in midday sunlight.  You might consider having the installer pull new #6 wire. 

--  Or you could wire the solar panels in series, which would double the voltage, assuming the controller will handle the higher voltage.

--  The down side with wiring the panels in series is, if you shade even one solar chip on one panel you loose almost all output from both panels.  If the panels are in parallel and one part of one panel is shaded, you still get full output from the other panel.

It would be good to use a wire size calculator like this one from Blue Sea and check what your voltage loss will be.  I would shoot for 1% loss if possible.  Just remember the wire length is the round trip distance, the length from the combiner box to the controller times 2.

Thanks Al. Panel matches, running in parallel and we will see about the wire size.

Sometimes things are meant to be. My regular solar supplier had the panel available; he delivers to my installer once a week and that is on Weds; called my installer and he can fit us in on Friday AM. Just rolling along.

Just a tag on bit of reminder info for those who use Lifeline's and Magnum Inverter/Chargers. In Feb of 2017, Lifeline alter their charging parameter's just a tad. I called Magnum to see if they'd be making any software updates to the AGM1 setting, and they said the only way to do that was to send the unit in for a new board, or buy the board and swap it out yourself. So, they recommend just using the Customized profile, to alter the charging parameters to Lifeline's new recommended values. 

Probably not a major difference for many, but as I understood it, the new value was to ensure Lifeline's don't 'walk down' to a lower top charge level. So, worth the research and the 10 mins it takes to set a Customized profile.

Again, just a repeat of this info, not targeted specifically to this thread:)!

Best to all,

Smitty

New panel now installed and working. Installer said we can probably fit 6 panels on the roof if we wanted. We will see how the 2 work and then make a decision as to a third. Installer and supplier say up to 3 panels can run on our #10 wire, then we will need to switch. I seriously doubt if we would go beyond 3 panels. This rig just uses so much more electricity than our 5th wheels, all that technology.

Next project is to add Bluetooth to our MH. 2015 model and came without Bluetooth!!!! When we have a chance we will get the Jabra Freedom and try it out. Fry's Electronics carries it. I'll need to see if they will match the Amazon price.

Always something!!!!
