From what I've found, Mpp uses a scale of 22v=0%, 29v=100% and its not changeable, and is for all battery types, user defined is what is to be used for Lifepo4.

1,3,5, are every thing on, and grid voltage seems to pass through to output, 2 is with grid off and inverters are producing, 4 is with solar panels off and inverters are producing. and 5 shows the mppt's of the inverters coming back on line. If the solar is removed to a separate controller...

I have found some strange stuff too with the LV 2424's. As long as they are tied into solar, and the grid I believe they act as a UPS, and only maintain a a float. The only way I got them to start and stop charge was to tie my solar into a separate charge controller. I know have 5, 4 are split...

I had noticed in several of his videos a separate charge controller, when I was having problems with trying to get theses to run on inverter output only. So I tried and have found that as long as there is a solar input they act as a UPS would. 1,3,5, are every thing on, and grid voltage seems...

SOLAR ASSSISTANT IS AWSOME!!! It is a great tool, if it wasn't for this program I don't think I would of ever of seen this problem with the MPP software. This is with #2 inverter on. This with #2 inverter being turned off and with a test to make sure settings were registering and staying...

Been all over that spreadsheet, but I think I found the problem, and am under test now. I was reviewing the inverters in the mpp program and found 3 inverters were sensing the battery's at 100% and 1 was sensing battery's at 64%. So i turned that unit off and will see what happens.

What I believe i was seeing, is that power was going from the grid continually to keep the battery's in a float which was set to 27.3v. My lifepo4 never go there and in a relaxed state they might hit 26.4v on a average. My next try I'm going to set the Float at 26v and see what happens. In a...

Crazy, Been running in battery mode for a couple of days, brought battery's up to charge on their own switched this morning to solar, with the float down to the lowest, solar was reading volts no watts, turned the float back up to 27.3v the solar started recording. ???? This time the Solar Power...

I still haven't heard from my battery manufacturer but to my understanding BattleBorn says turn float off or low enough to turn the grid off, Lifepo4 don't self discharge. This in re the battery, I don't know how the MPP will react, but I will give it a try this weekend when I'm home.

I have had a weird one going for a while and haven't figured it out. Are you familiar with these Hybrid's. No matter what settings I try I have not been able to keep the Grid from coming on. I'm starting to think that I miss understood the operation of theses Hybrids and got the wrong thing...

Nice, I thought their was something else I haven't found. Early this morning I turned off the Hybrid mode, Ill see tomorrow what that accomplishes. Since I'm running in split phase, I have noticed a difference in what the Solar Assistant see's, I should have available 2.4k per leg, I split legs...

The morning of the 12th I changed to your settings in the Mpp, the morning of the 13th I deactivated the maintain battery state of charge in the Solar Assistant trying to get a more constant solar to go somewhere. I've been seeing in my power wall that the Mpp has been keeping them in a float...

I'm really liking it to, just playing with setting to learn what each has for an effect. Still haven't got the grid all the way off yet, one setting a day to see what happens. Your settings got me started this year, ran solarwatch last year.

Have you started to get the hang of this yet, and what the MPP setting do?

I have also put together a battery tester out of a Victron Smartshunt, and picked up another to put on the main supplying the LV2424's permanently.

Good Morning, been a while. Winter is over and back into Solar production. Made some big changes for me and it seems to be working well. Fist off I went to a new program on a Raspberry PI for monitoring, and took the panels off the Epever charge controller and put them back on the LV2424's...

Been cycling too a charge rate of 28v, my relaxed state is 26.3v on average.:(

24v system, If you want your batterer's to settle to the relaxed state of 28v, do you want to set your charge rate , to be set 1v above to not damage battery?

I don't understand? 1. I topped all battery's for separate top balances, with intent to do a full parallel balance. I gained a total voltage to 26.7v relaxed. A. Performed a load for a day, with a one time 15 minute 53% load, the batteries dropped to 26.2v, and after 3 days use the relaxed...

I believe I have found my Issues. I have learned after reading other articles that Capacitance is a constant, which is lets say physical. The range of operation, in my case was balance. I performed these tests and could not understand why they were not more uniform. Each line is a Battery. So...

What is the difference in-between top balancing or bottom balancing. I would imagine it means what it states. They either start together or they end together. I would think that top balancing would be better in a parallel application.

No. 27.5v battery charge setting, batteries were only charging to 26.1v, have now increased to 26.5v. which is the 1 volt difference your system does, mine should be going to at least 27.2v. which is the .3v. thanks for your time

It will be over a week before I know if more capacitance has started come back, at the 20a CR. Would like to see under 1v difference. When I first fired them up it was .3v.

If I see 27.5v on the meter, that means the charger went to 27.5v and quit. So it has been verified. As of this morning the battery's have increased capacitance another .2v on the 20a CR.

That is on the bus bar battery parallel main. This is just a pic. not at the 27.5v I have seen.

Yes, I have a separate meter on the system and I physically see the 27.5v, and yes I don't know why the batteries never go there and stop short. At 10a CR it was worse, and at 30a I thought I was burning them up.

I'm using the lv2424's auto charge rate, settings are 27.5v/24v, stop and start. Amps can be set between 2 and 60. Charger hits the numbers, the battery's are coming up to 26.7v, when the charger kicks out, but only holding for a max of 1 minute. they are the BYD 24v plug and plays.

I've noticed in mine, since I've been running a constant 20 amp charge rate they have came up .3v, on the top end. I must have cell issues because the top end is not constant, the highs have been 26.5v with a average of 26.3v. New to me was 26.9v.

Ill go back through my browser history, see if I can find it, should of kept it. It was a university that was studying chemical breakdown in the battery. Yes I typed it wrong sorry. still have got nothing back from Deligreens.

As I noted a couple months ago, looking for the sweet spot in charge. Went back 3 computers ago, win 7 got constant readings, and with net search found no lipo4 battery should be charged at over 20a.

Just checking, I goofed and had to dig my mount hole twice:confused:, I guess I got excited noticed the shade 1 morning about 2 foot in. Hate doing things twice.

Mount looks good. Did you notice the solar shading? I noticed it in several pictures, is it trees? The shade line looks straight.

Its about $450 to me per pallet, 2 per from the 2 California suppliers. I think I found them http://www.deligreenpower.com/deligreen-products/154-en.html#ad-image-0 last time I got stuff from china it only took a couple days:) Ill request a quote.

Do you know of any Byd cells available for packs? Never had one apart yet, and never seen one. If its not available, and if I have a issue I might just build New.

No these are byd full packs not broke open yet? I have 4 plug and play units in parallel which I got from 2 suppliers. kind of thought that doing a charging amp rate test now, trying to determine where to start. What is a Headway?
