Hi all,
(Forgive the long and winding ramble!)
I've inherited a non-completed Solar Install. My Dad was making a bus to rv conversion, and it got held up. 6 years later, the guy who was going to set up the electrics has shut shop... but Dad has all of these parts. All that was missing was the batteries, but it was assumed (at the time) AGM would be used. The time has come to finish the install and I've done the wiring, mounted the panels and components, etc, etc. But, still without any batts (I've been using 12v Lead Acid to test the system).
So, I've been lurking here, watching Will's vids for a few weeks now, coming up to speed with everything lipo, and was getting really excited about DIY'ing a 280ah 12v lipo and was reading up about float and bulk charging...which caused me to re-read the SCC manual (which also has a DC-DC converter) to see what it said.
The problem/question:
The SCC (and the DC to DC part) allows me to set Bulk and Float settings. No problems there...
But I read in the forums here that lipo hate Float... I assume that's correct...?
But this thing is a multi-stage charger and can only set the two settings. I can't set any absorption time, etc, etc.
I found an updated copy of the manual for the controller and it says:
"The solar controller may only be used in PV systems for charging Lead-Acid type batteries. This includes: SLA, VRLA, Lead-Calcium, AGM and GEL."
(My hard copy of the manual doesn't have this, but it's *old*).
It also says it does "Multi Stage Charging with Timer Protection".
The device in question is a Voltech SCM030, it's a 50V 30A MPPT and DC-DC charger for 12v batts only.
PS: I've set the the DC-DC part to be wired to the 24v bus (aka car) system (the DC-DC part has cut in and cut out voltages, which I can set to sense alternator 'ON'). I know Will is non-fanatical about this type of setup....but hey ;-)
I was wondering if I can or can't use lipo on this SCC? I was under the impression that lipo could be used as drop in replacements?
If I can use it, I presume the default Bulk charge setting of 14.2 could be changed to 14.6. What about the float level?
Here's the manual for it (Voltech SCM030):
(also the same manual is attached to this post)
Any help or advice would be welcome.
Thanks all, especially for your patience!
