I think I'm going to take a combination of solutions. I do need to install a Class-T fuse, so that will allow me to extend the positive side. On the negative side, I'll pick up the proper connector and build a new cable.

I just got my new EG4 indoor Powerpro battery in. It came with lengths of 2/0 battery cable with the special ends that the battery uses. However, I'm a foot or 2 short of length to hook them into my existing DC bus bars. What type of connector should I use to connect high-current fine-stranded...

I've had 4 EG4 3kw inverters and 6 EG4 lifepower batteries connected to Solar Assistant now for several months. SA's running on a Pi 3 It's been working great, except for the past 2-3 months. After being up for around a month, the web interface starts getting really laggy, then grafana graphs...

It's all THHN. The existing conduit is an above-ground horizontal run around a shed that I installed in August and stuffed an 8/3 Romex into. The Romex didn't particularly like making the corner in the LB.

It's for a ground, though consulting the NEC table again, it should actually be a #10. The idea is to use the 3 #8s and a #10 for a 50-amp RV receptacle, and 3 #10s to feed a 120v single-leg sub-panel for up to 40 amps of critical loads like freezers.

Ignoring the NEC rule regarding maximum number of current-carrying conductors in a conduit, how easily/possible will this cable pull be? I haven't buried any conduit yet, so plans can change, but I'm seeking to integrate into an existing 1" conduit where I'll be pulling the existing conductors...

I submitted a ticket to SS tech support, and got back that I should be charging bulk/absorb to 58 volts, float at 54v, and set low DC cutoff to 46v. I made the corresponding changes, and what do you know, as soon as the batteries hit 58 volts, the SoC of all the packs went to 100%. Finally, all...

The charger is set to bulk charge to 57 volts, then float at 55.4. Looking at the graphs, it does indeed hit 57 volts on the main DC bus, right up until it hits 57, then clips solar and goes into float. Do I need to set float higher? I'm certain I'm doing something wrong, but I don't know what.

2 weeks later, and the batteries do appear to slowly be increasing in SoC when fully charged, but none have reset their SoC to 100%. Pack 3's cells appear to be pretty balanced, right until it hits the 100% mark, then the cell delta starts to grow. When it goes to discharge, the cells rebalance...

Yes, they hit 57 during bulk, then drop to 55.2 for float.

Bulk is set to 57v

I've been a few days now, and unfortunately, the 5 balanced packs haven't reset their SoC scales, and pack 3 doesn't appear to have balanced itself. Though, when not fully charged, pack 3's voltages no longer show the 100mv delta when it's fully charged. Yesterday I tried to apply the BMS...

I bumped float to 55 and absorption to 57, and we'll see what happens. My original voltages were set per the EG4 manual for the batteries because I didn't know what would happen if I exceeded them. This is my first foray into a battery that's not lead acid...

I have 3 EG43000EHV-48 inverters in split-phase backed up by 6 EG4 LifePower4 batteries. All of the batteries were purchased within 6 months of each other and commissioned at the same time. When charging the batteries, 1 battery appears to hit 100% while the others are around 70% charged. The DC...

I'm 95% off-grid for my system in its current state. After a couple poor sun days, my batteries get lower than I can reasonably recharge with the panels I have, so I have the grid hooked up to recharge during those periods. I have 4 of the EG4 3kw inverters in split-phase mode hooked up to 30kwh...
