I’m trying to figure out how to make a BMS cable from my LV 6548 by new ECO-worthy battery. Has anyone been able to figure this out? I guess I could make a cable if I had the pin out for the LV 6548 and the pinout for the ECO worthy battery.

(14) 250w panels total. Configured in (2) strings as series parallel. Each string is 7 panels.

PV:
Fuse rating 15a.
short circuit current: 8.86a
Pmax: 8.27a
open circ voltage: 37.6v

In series-parallel i should be generating about ~16a, being only (2) strings if a string shorts

I want to run 4kW loads on a 120V 15A shop circuit in bursts of about 500 Wh.

Apex 300 can do this, but it has pieces I don't care about (DC, UPS, 240v, etc.) and 4kW is right at the edge of its capacity, so maybe DIY could be cheaper or better.

I am considering to buy:

- a 48V battery than can supply 100A continuous.

Lo...

Just picked up three eco worthy 48V 100 amp batteries and installed the app. Right now all three show up with their serial number, wanted to see if there was a way to go in an edit the info so that I could rename? Has anyone been able to do this? Looked thru the settings but did not see a way.

I'm switching out my battery banks to lithium and from what I've been reading I may need to switch from ANL to fast/slow T-fuses? one inverter will be just one battery and currently has a 300A ANL fuse after the battery. The other inverter has a 500 amp fuse after parallel batteries. Do I use the same amp rating and do the T-fuses need a fuse holder or can I just bolt them inlin...
