I bought the 190ah battery pack and am charging it with the 12V MPP solar all in one off shore power right now. The 4 cells arrived very well matched matched at 3.1V, which I thought was a bit low. The pack wont seem to charge past 13.55 volts. I do have the daly BMS 100A on it. I'm new to...

Buy the remote display screen. Maximsolar (or something like that on Ebay) sells them with a different communication board. Works great and you can turn off the inverter from the remote display. It's not the prettiest display but seems to do the job.

Yep. It seems to work well with just a slight delay. It can only be surface mounted, and is kind of ugly, but those are both things I can deal with so I can bury that fan as far from my ears as possible in my little trailer.

I asked this question about the MPP Solar units because their 500W max input on the 12V PIP LV is one of their biggest limitations. I was told that if the input goes over 500W the unit will shut down. This limits the ability to put 6 pannels in a 2P3S arrangement which is good for limiting...

I can try to discharge it some and check it tomorrow. I will be getting a hall effect monitor in the next day or two that is the best meathod? I received the response to my questions about the limited charge cycle from the Maximum solar Ebay seller that I bought it from. It still doesnt...

the watt meter shows the peak draw and average. Plus, I have tested it with my battery and the inverter and it was fine. I actually ran it for a while as my discharge source when testing capacity on my batteries.

If you read above the distributor told me this is a safety feature in the MPP. Since I am still getting full capacity and it is better to not fully charge anyway I am just going to leave it.

Yeah. It just seemed to be sitting exactly at this voltage for a very long time with no change. I just asked jason at BLS and he said "this is normal", so not 100% sure.

I'm using the utility charger. I don't ont have it in my trailer conversion yet so no solar. Should be charging at 20A. That is the rating of the utility charger in my unit.

Yep. I realized the same thing

Yes

Well, I hooked up a hall capacity monitor and ran the batter down to 10.4V . I got 2400 kWh which is a 200 Ah battery, so even if it doesn't charge to over 14V I guess it's no biggy. The only weird thing is that the reported load on PIP was lower than my monitor on the small A/C I was using...

I managed to use an M6 tap to get another helicoil in. I couldn't find an M7 and didn't want to go to M8 unless I had to. I have battery assembled and in a battery box with secondary cable connection points, so hoping it will be fine as long as I don't have to disconnect and reconnect any time...

I've thought about this becasue the internal MPPT Charge controller on my MPP solar 12V pip can only handle 500W and I would love to put 6 100w panels on the roof in a 2p3s arrangement but in the colorado summer sun I imagine we could bump past that 500w limit on the right days.

I got 400w of solar installed on the roof and am a little perplexed by the numbers going into the battery. They are connected 2S2P using 10ga wire The voltage and amps make sense, but the reported watts in doesn't add up. Thoughts. 36Vx9A should equal 324W (which does seem high given where...

That's great. For future refence, this isn't how you talk to people when you want to tell them about a good deal you found. ?

This discussion is making me feel better about the fact that my MPP Solar 12V PIP is automatically cutting off charging of my DIY LiFiPO4 pack at 13.6V (it then settles to 13.4V). It also helps that I did a capacity test and it came out at the rated capacity. I have the bulk charge voltage...

I've also found the fan running when the inverter is off and it is just charging off solar. Not sure why this would be. I thought there was a setting that might improve this, but can't find it.

I started this discussion in another thread, but decided it should have it's own discussion. I have a new 12V LiFePo4 batter pack I built from cells and a BMS ordered from BLS batteries on aliexpress. I am charging with the 12V MPP solar LV PIP unit that has a 20A utility charger. I dont...

I'm measuring with batgo battery monitor and balancer. When I disconnect the battery from the PIP unit or turn it off it drops to 13.4v or so. i have confirmed with an electric tester. MPP PIP unit shows a matching voltage. charge voltage in the MPP PIP is set at 14.6v per battery...

So a brief update. I've connected and disconnected the battery about 5 times. The other day. One of the terminals came apart. I contacted BLS and they were completely unhelpful. Anyone know how to fix this. Dave

I got an M6 helicoil to stay, but it's not going to hold up for too long. The M7 kit seems like a good idea but I can't find M7 terminal studs. They look like set screws to me and I can only find them even sizes. Maybe I'm looking for the wrong thing. Hard to search for stuff online when...

Thanks! now to figure out what to buy and how to do it. family is on isolation lockdown due to severe immunocompromise in my family. could be in this state for a couple of months. Any suggestions for sources on taps, inserts and terminal studs?

Maximum solar on Ebay sells the 12v pip for 265 + 80 for shipping. Seemed reasonable to me.

I am going to be converting a 7x12 cargo trailer into a camper/travel trailer. We will keep things pretty basic but are going to be using a small 6000btu portable AC unit to cool it off when needed. Mostly for the dog when we cant take her places like in national parks or restaurants. It...

I have tested it with a watt meter and the peak draw was 610-620 watts. I had the same concern, but I think it will be fine. How well it will cool is the bigger question. It is a single hose design, which is not very efficient, but I plan on venting the intake as well which will make it...

Well after all that talk of things smoking I'm not sure I want to find out. ?

I tried that too as a test. I agree it would not be wise as a long term setting. It didn't seem to change anything. I don tthink it is a big deal. I got the full capacity from my battery.

I emailed MPP Solar about this. They asked about which solar panels I am using and since I hadn't bought any yet I told them I would be using 6 HQST 100W panels in 2P3S arrangement. and provided specs. Here is the response I got. ------------------------------------------------- HI...

Thanks guys. I can test it a few more times, but off my battery with the inverter in this it started up fine. including cycling the compressor on and off over time. Any other suggestions on my schematic? should I have a disconnect switch for the solar for when I remove the battery over winter?
