I am having a similar issue on a daly 500a 8s and a clone 8s 250a. Both just decided to stop sending data about their status and allowing access into parameters but the mosfet indicators show up. I downloaded the old 2.0 apk(correction edit) and got it to show this but its not updating and the...

Has been roughly a year with the Eccotemp. Havent even gone through a 20lb tank yet. My only real gripe is that it does not seem to care if hot water is coming in so I have to manually turn it on and off as needed. I thought a unit with digital controls and a screen would be smarter.

Is heating an issue or are we just dreaming about air conditioning in this post? I just retired two Midea U (8K + 12K) in my tiny house in favor of a lesser efficiency mini-split heat pump. A worthy sacrifice as I had plenty of power in the summer, but was left to chopping wood all winter for...

Do this across all the cell groups. Connect all your - together, then all your 1+\-2 bars together, then all the 2+\3-... all the way up to all the positive terminals. Be super careful... or your ring lug will turn into a spade. Edit: i had occasional connection issues, lock washers are suggested.

I am actually retiring a set of 5. I used one dalygreen BMS and paralleled 5 packs with it. #6 x 1/2 self tapping screw can conveniently attach a ring lug to the fuse strips. The more cells you parallel the better your balance will be, at least in my experience.

I have already ordered from Midwest Steel Supply, but got an email about a 14 day backlog. They are cutting everything to the length I need before sending. McMaster was going to cost about 30% more and I would've been cutting them myself.

I got fuses in today, still waiting for bus bars

Btw didnt realize I was responding to you Will, big fan great vids... Im at 14c/watt including the 250A BMS

Here is the link to the ones I purchased Grade A+ lithium iron phosphate battery cells 3.2V 310ah lifepo4 battery for Electric Power Systems https://m.alibaba.com/product/1600215997258/Grade-A-lithium-iron-phosphate-battery.html Edit: It looks like they have changed to 310ah where I ordered...

I am looking for bus bars so yes there is some plumbing strap used here for now. Ive run my maximum current through it as it is now and checked for temp rise, barely noticeable. Never intended it to be permanent I just ran out of bus bars while my power was down. There are actually 3 pieces...

Thank you! Has been an ongoing project. As for the rest of the crew, 250A SouthROL BMS (Daly clone) 2x Epever 8420AN MPPT controllers - 2kw and 2.5kw arrays @250w-2s4p and 2s5p 3500w/7k surge Edecoa inverter

Reorganizing upstairs in my 400sq ft barn-house. Planning to loft my bed and have a closet underneath, so have been rearranging everything. Also just got my newest cells, 302ah grade "A" (but really B at best) built into a pack (8s4p). Very happy with the outcome! Still have to wire the tired...

Looking for some copper flat stock to use for bus bars. Can go up to 3" wide, up to 1/4 thick (atleast 1/8) , need 6 pieces 21" length and 2 12". Can cut and drill etc just need that much to do the job. Also need a plate, at least 1/8 upto 1/4, 4" x 10". Does not have to be new and IDC what...

I tried one out, and was not pleased with it. The good: it will program all your controllers in one shot via usb The bad: the mt-50 display becomes useless Mine had a strange error once and reset one of my controllers to a weird ID I didnt ask for... but by inquiring the channel via direct usb...

Just wanted to add to Hedges awesome answer. Can also buy 24v elements, I ordered 2 900w 24v elements off Aliexpress and they work fine. You cant use the internal thermostat directly going this route, will need a contactor and thermostat seperately but it does unload the inverter. I found my...
