Please confirm if there is partial contact in your connection, shake the cables a little, if there is a loosed cable tighten it, if not then

Buy original knife switch and replace

Confirm your load wattage and wattage of the knife switch in use - It’s probably not a rating issue though, but check, there may be a need for replacement if, you find the issue still persists

Good morning

Check this type out
Preferably you would have taken a pic of urs.

But for that load that shouldn’t happen at all

I think is the same as mine, hopefully it needs to be replaced

Good day All,

Please which inverter model (24V) is pocket friendly apart from Hybrid inverters (Axperts models) that can charge Lifepo4 battery. I need to get a stop gap for my MPP Solar hybrid inverter that have refused to come up or show any light for some days now. The inverter is less than 3 months old and I have contacted MPPSolar support.

Thank you.

Yet another Axpert bites the dust!

I truly have been unable to trust this entire family of hybrids to perform under demanding conditions.

I am looking right now for a basic and reliable inverter in the 5kw range to play with and test out some new ideas but keep coming up blank. I already ruled out all Axpert and Mustpower types and their many clones

Reason I'm looking for something different from Axpert family before buying another one.

Yet there are many that are still running theirs for years. Ofcourse we can't expect axperts to perform like the high end Victrons, Deye etc just as they are not in same price range either. Having used both MPP and Deye I will still recommend them depending on customer packet.

I think they are okay within a particular price range - I just do not think they are robust enough to trust mission critical work to.

The Axperts seem to have a particular fondness for spoiling easily and needing a board change. The Steca I last tried in 2020 just randomly started drifting on DC measurements and ultimately gave up the ghost. Mustpowers are similar in that the control board ultimately fails and you lose a key piece of functionality. You generally have to change the whole board too. Heck leave the inverter idle for 6 months and you may find that the board has already failed on its own.

I very rarely hear that an SMA or Magnum or Victron inverter failed. When that happens you can usually clearly pinpoint the user error or catastrophic event that caused failure. They simply do not fail under normal (ab)use.

But your MPP also had a problem at a time and you had to replace the board. I still believe that the best inverters to buy are the first tier makers like Outback (I have a 7-year old outback), Victron, Schneider etc. I currently have a Felicity hybrid running for several months, but I bought it with low expectations. But, it has been fine so far. Caveat: It is only inverting, rarely charging with electricity and never connected solar panels to it.

So, how does one know which inverter is an axpert variant?

That's right at least I have an idea of the cause and thanks to MPP replacement warranty. Nevertheless those "first tier" are sure thing so long as the user's budget is sure as well

Structural design and interface will give you a clue

Please what was the cause

Peterlove11:


Please what was the cause

Was using a relatively aggressive equalisation on LFP, made the BMS react in a way that impacted the inverter. It was after I learnt you don't equalise LFP or at least not at high voltage and not prolonged.

IYGEAL:

Most hybrids are

Okay. But MPP seems different in structure from most.

I see

My Oga. Finally we have your confession

A battery disconnect due to BMS HVD limit reached should not kill an inverter.

There are many scenarios where inverter could be doing heavy work and the DC side disconnects due to low battery, DC breaker trip due to overload e.t.c The inverter should recover from these gracefully.

I know the tolerances on the internals for these Axpert types are relatively poor although they keep making improvements - a capable person can also perform hardware upgrades - beefier capacitors, changing the fan e.t.c

Get this... 4k-5k for the 100A depending on the brand and your area. There's A&Bt and MG

We still give the most safe, professional, reliable, and classic installations...

Akwa Ibom based but install anywhere in Nigeria, apart from the Northern regions.

So after a lot of back and forth,
Am back to this lifepo4 group buy matter.

Due to less than stellar performance from several china shippers, i have tried.
Am considering the safer option of the alibaba seller handling the shipping.
He says his minimum cargo is 1cbm which is 64 pieces of Lishen 3.2v 272ah batts, cost about $550 customs and all inclusive, and pick up in their lagos warehouse. I only need 32 pieces, hence looking for possible buyers of the other 32 cells.

Each cell is about $80, and shipping duration is 3 to 4 months

The chinese new yr holidays is coming, commercial activities in china will grind to a halt from early feb and pick up again early march

Reserve 8 cells for me when the groupy restarts

My Oga. Finally we have your confession

It's not the first time I mentioned it as a possible cause Oga. I wasn't home when it happened but I know I had an aggressive equalisation plan set-up and it's the only thing I know was newly introduced before I left. The sign of a burnt section on the board also further makes me gave the impression.

Yes it shouldn't as indeed I have had battery disconnect due to HV on the same MPP many times without issues, just that the one that cause issue was with equalisation. Would a victron have done a better job maybe. However that's not the point, I have only stated what happened to mine. If any axpert user wants to prove me wrong they can continue to use equalisation for their LFP else they learn from my experience.

Good day people, please does anyone here know where I may buy impulse (bistable) relay. I don't have time to wait for AliExpress.

Oga why don't you want to go to the northern regions, na there money dey pass, especially Borno

Haha! Have you been there yourself? Wisdom is part of valour!!! I think the long distance from Akwa Ibom to Borno is the issue or also the sun there is too much ; it might crack solar panels if installed there. I am sure it's not due to the bullets or RPGs that might be flying around............, or am I missing something?
