DIY forever There is no shunt trip breaker at all. There are fuses on each battery, 1pc 250A breaker for the inverter, 3pcs 80A breaker for the charge controllers, 5pcs 63A circuit breakers for the solar panels. The BMS is connected in a way to be able to switch off charging through the 5...

DIY forever.

Glad to hear you like like it and thank you for your kind words. The straps over the top and sides keep the batteries together firmly. The Batrium is the best I could find that allows batteries in parallel (1P16S×6 in my case) without having to worry about balancing at the cell level. Downside...

I came up with the idea because of space constraints. I used 3 straps for my first build, but I decided on 4 straps for the second build. The build was done on the ground and lifted to position. 16 cells sit on a modified pallet, strapped together with the batteries. I figured I'll have a...

DIY system with the following: -3 Morningstar MPPT-60. -1 12Kw Growatt 12 KT HVM. -1 Watchmon Core + 6 K9s + Fan. -1 Batrium 500A shunt. -96 Eve LF280K mixed a little bit. -5 Gigavac Contactors P195FDA to control charging through Watchmon Core. -Board to the right for spares. Sorry for bad pictures.

I am experiencing the same problem. Whenever it happens, the state of charge as shown on the page goes to zero, and there is a fault event set on the page but not on the inverter.

Well, it depends on the BMS you have. What is the model of your BMS?

You are right. Anything else?

Should I ask you same?

Oh, you mean a conversation? Didn't know you call it an email in the south. The only message you sent was what I posted. There was no other explanation. Could you should me this explanation of yours?

Stop lying. We never had any email exchange. Curious though, how do you top-balance cells individually?

Thank but no thanks. A cell swells while top balancing. I wish the buyer of other cells good luck.

Thanks for the information.

Oh really? You offered $100 each but I said it was too high for damaged cells. I never offered you anything because I didn't want damaged cells but I pointed out the price was high and I felt others should know the condition of the batteries by quoting you and leaving out your $100 offer which I...

Important message from the seller: "A couple of the batteries have swollen a bit due to a defective charger when I first got them and was leveling them, just FYI..."

I wish to buy 8pcs without BMS. What is the price?

I am not sure why good intensions matter at this point. Could the fact that the person that screwed you didn't intend to screw you from the beginning makes you feel better?

Thank you for your recommendation. I now use Gigavac.

You may just be more knowledgeable about the DCC than Chargery as a company. ? Thank you for the insight.

I hope you know that the max voltage rating of the Chargery DCC is 100V. Assuming you are right, should Chargery not provide this information to us?

PV array is 76V Voc.

Yes, it lasted for about a month and failed. I never trusted their BMS from the start, I went for Electrodacus SBMS0. Thank you for your kindness by the way.

I used it between PV and Morningstar charge controller. Highest current input was <40A for a 300A DCC, yet it failed. I have been lucky to have the charge controller come to my rescue to avoid overcharge. That thing is dangerous ⚡⚡⚡.

True. Only one worked and that one is also history.

Chargery DCC is simply a piece of sh*t according to my experience. I now have five failed DCCs: 1. DCC300. FAILED CLOSED 2. DCC300. FAILED CLOSED 3. DCC300. FAILED CLOSED 4. DCC300. FAILED CLOSED 5. DCC100. FAILED CLOSED None of these was used between battery and...

Can the Bluesea 7713 accept a power source for latching (through the red and black wires) that is different from the power source going through the A-B terminals? I intend to use 7713 to switch power (on/off) between the solar panels and the charge controller while using an external power source...

I can buy it only if you are willing to ship them to NJ.

I wish I could believe that. Scam may or may not start with good intentions.

Who would have imagined there are scammers outside "China". :confused:

Yeah, as long as he's paying for shipping.

Michael sent me evidence that shows the Alibaba case is still pending. I wonder why he won't post it here. He seems to be working behind the scenes but lacks the ability to communicate properly.

Michael asked me via chat to return the batteries to him, this issue isn't a rumor.

How cheap are these batteries exactly? Assuming they are half the normal price, should we not get the "cheap" batteries we paid for? Should we blame ourselves for wanting "cheap" batteries? For instance, I purchased 16pcs 302Ah grade A batteries but got used, damaged cells instead.

Let's say you are right, how is that the concern of your buyers?

I mean if you open a Paypal or any other case, he takes his time to fight it so you don't get refund. However, he's too busy to respond to anyone else.
