    SHENZEN BASEN 280Ah, I received my first order

    I am going to correct you on this statement of it being their "LAST" famous words.. Typically the folks that do this come onto this forum and rant allot and blame blame so they have lots more words that are just as famous after they bloat their cells so by definition it is not their LAST...

    No, You missed it then! All arrived on the same slow boat from China to LA Port of Entry. But FEDEx decided to send them from LA in FOUR DIFFERENT FEDEx Deliveries.

    Heads Up Alert: Li-Ion & LFP prices going UP this month.

    Has anyone contacted EVE directly on this ceasing business with individual sells around the world? Which sellers are stating this to be true? I don't think the problem is with the sellers but with the buyers. A major manufacture uses a secondary channel market to maximize profits per Adam...

    Resistors for bottom balancing (25W, 2.7Ω) -- where to purchase?

    I am assuming you are going to use a BMS. If so most of them will destroy your bottom balance by top balancing them passively by trickle drain down every time they are fully charged, some passive have as much a 150 ma drain down. Some folks here use BMS with active balancing that uses 1 Amp or...

    Schematics for all in one units

    I don't know about other manuals but I thank you for the one you posted. I have the 800W MPP. panels, & batteries set up as a back up UPS so I am saving the manual you posted. I agree a "Better" service manual or for other units would be helpful. As for the horror stories ..... its the Chinese...

    Expected output of 4.2kW system?

    Eleven years with no idea and no maintenance is on the long time side of things. The answer to your question: 72Kw-hr for 22 days on a 4.2KW system is totally unacceptable unless you are way up in the artic circle during winter (22 hours of night) or you see your neighbor NOAH building and arc...

    1 BMS or 2?

    If your batteries are new, matched, and balanced the only definable gain with two BMS's is redundancy of system. That is if something happens too one cell or BMS you can still limp along with "half a battery" if you absolutely can not be down at all and having at least half a pack has huge value...

    MPP 2424LV in parallel: One box making more amps

    Not enough information Probably perfectly normal! No worries. Possibly something amiss like cable/lead/connections. Most common reason if amiss is the resistance on one lead/pack/battery/etc is higher than the other lead/pack/battery/etc ......with most likely cause being imabalance from user...

    Battery Charging

    Yep.....voltage and amperage is conditioned by the MPP to a lower voltage and limited current.......set by the settings..... to what the battery likes to digest without damaging them during charging. That's why you spend all that money for this thing. It will stop the charging when the battery...
