Considering how cheap these are for low current, I think I'm going to start with this and just monitor the battery stays at around 90% charge. Thanks.

Ultimately yes, but I'm looking at making the system as robust as possible so that I can work on some other projects in the future that would otherwise fail when the battery system fails. The install is at a cottage a 4 hour drive away in northern Ontario so winterizing is a real issue and if I...

I'm ok with slow charging since my application is pretty low power. Even the 48/12-9A is overkill for what I need. Having the right profiles for this application as you've stated is what I'm more worried about. Don't really want to fry a $400 battery because I "saved" $100 on charging it with a...

Hi all, I've got a 48V Lifepo4 bank being charged by two MPP Solar 3048 units in parallel. The whole thing is at a remote off grid location that I don't get to for a few weeks at a time and I'm setting up some remote monitoring stuff. I'm going to be hooking up a Raspberry Pi running Solar...

After everything, I connected my panels to my second MPP unit again and it works! Maybe I just didn't give the mppt tracker enough time previously to figure itself out. Looks like the other unit is somehow faulty, luckily it's not super critical I have them both running right now. I'll post...

Thanks for this. My problem isn't that I'm not getting any watts through (although that's the next step) it's that the unit isn't detecting any voltage from the panels. I'm at a pretty remote cottage and I didn't even think to bring computer, I've been doing all my settings on the unit's...

No, this was the loose wires making contact with each other since I bypassed all my disconnects from the panel.

Coming back to things this morning... The issue is not with the panel wiring which I can guarantee by an accidental arc flash about an inch and a half long from the wires that go into the MPP when I was trying to rewire something. I'm at a complete loss as to why the MPP unit is only reading a...

I've gone back through the connections at each of the panels. As the sun is setting I'm getting 120V on my tester and 4V on the MPP display. I'm taking my neighbours advice of "Drink a Scotch and sleep on it. Better yet, make it a double."

I'm on really poor 3g service and the upload isn't quite liking it. Really there's not much to picture - I go from PV +- on the MPP to a disconnect, from the disconnect outside to the shed with a PV combiner, up to the panels (in this case, just one now). I've now bypassed the combiner and the...

I've now gone through a few permutations and bypassed my PV combiner. Even one panel, reading 20Voc on my meter at the MPP is giving me 0V on the unit display. Tried with 4, then 2 panels before trying with the 1 and always similar results.

Hi all. I've been lurking here for a while but now that I have my system installed I have a real head scratcher that I can't figure out. I've installed two MPP Solar 3048 units in parallel along with my new Lifepo4 16s 280ah 48v battery system. I had some trouble but I've got the battery...
