Thanks for the response. A couple of questions. So let’s say I were to move the kitchen circuits that power our refrigerator and freezer to the critical loads panel. I would connect power from the main breaker panel to the inverter AC input and AC output to the critical loads panel. Then as long...

I just went to the basement to check the voltage of the cell I’m charging. The cell measured 3.37 volts and not the 3.45 volts the tester thinks it’s at. I wonder if that accounts for the weird looking charge curve? I’m monitoring the charge from my master bedroom remotely on my iPad so I can...

Thanks that’s good to know.

I don't have an answer for you but I like your "lightning fast chicken plucker patch!"

Andy's latest video on how the Daly BMS balances is very enlightening.

Thanks for the detailed explanation and the pictures!

I might have to take the bad A40L apart to see if I can troubleshoot the problem with it.

I am new to this forum and new to Solar. I have a basic knowledge of electronics though. I am trying to get an off grid solar installation going for my house. I have purchased solar panels that I will install in the Spring. For now I am trying to build my own 24 volt battery pack. I recently...

Thanks. For the critical loads panel other than breakers for the circuits, would you have a main breaker where the inverter feeds the panel? And I’ve spent the past two days reading through the manual.

I’ve come to the same conclusion. Too good to be true. The case and hardware with BMS should be close to that price alone, without the cells. You can buy the cheapest 280ah cells for about $1300 delivered from China. So the cheapest you should be able to build a comparable battery would be...

Hi, I wound up with 8 Lishen 272ah and 8 Eve 280ah, all supposedly brand new. I plan on building two separate banks of 8 each Lishen and Eve and series connecting them with each bank having its own BMS. Has anyone actually done this? What was your result, any issues? In addition, if this works...

I know this is a simple problem, and maybe I’m just not understanding how it mounts, but should a breaker slide back and forth on the din rail? I have tried three different ones and they all mount, but I would think they should stay in place? My don’t. They all slide back and forth and won’t...

Rechecked all connections. I know that the wiring of the sense leads to the BMS and cells is correct. I did re-torque all the bus bars, they were already torqued to 4nm. The BMS ring leads were all crimped and soldered. Sense ring connectors are directly on top of the bus bars, and underneath...

These seem too good to be true. First of all the listing says 280ah, when the label clearly says 272ah, possibly Lishen? But what really stands out to me is the price. $320 for 4 cells with free shipping from China? Something‘s not right.

To make it do what I would want would raise the price to about 90k. No thanks! 40 mins just to charge to 80% on a fast charger? This article shows that hauling 10k lbs will cut the range in half. So 115 miles off your lucky. So much for hauling an Airstream like what is pictured in Ads...

I have 8 each Lishen 272 ah and Eve 280 ah cells that I want to use together to make one 48 volt battery. I'm pretty sure that I can't just connect them all in series and use a 16s BMS. But can I create two 24 batteries each with their own BMS and connect the two batteries in series to make a 48...

Hi, Does anyone on the forum have this inverter? Has anyone tried it without batteries? This is one of the units that when used alone, not in parallel can supposedly work without external batteries. My question is, without batteries does the unit draw power from the home AC? Can I test it...

Thanks I’ll do that. I have some good #14 wire I can use. And hopefully I can get more current flowing.

Hi, I want to build a DIY solar system, using ground mount solar panels, a home built battery bank and all in one MPPT charge controller and Inverter. I plan on this being a backup for the utilities and it will not feed the grid. I went on the PIke’s Peak Regional Building Department’s website...

I am trying to test Eve 280 cells using my Ebc-A40l tester. Just a note, I have already tested 8 Lishen 272ah cells with this same tester without any issues at all. However as soon as I attempted to run the same discharge and charge test on my Eve 280 cells I am having problems. Both the...
