    Splice connector for 2/0 wire

    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...

    Solar Assistant on Pi4 not staying connected to EG4 Lifepower batteries

    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...

    How easily will this pull be in 1" conduit

    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...

    Uneven battery charging and can't get to 100%

    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...

    EG4 3000 utility charging settings

    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...

    Neutral/Ground bonding on 3000EHV-48 inverters

    With the recent video from Signature Solar regarding neutral/ground bonding recommendations and my permanent install of 4 3000EHV-48 inverters in process, I'm thinking about how my neutral/ground bond should be configured. It looks like SS's video is specifically in regards to their 6kw units...

    Class-T fuse sizing sanity check

    When I built out my system, I included a Class-T fuse holder inline with the main cable coming off the battery rack bus bar. I'm using 4/0 105C-rated welding cable from the battery bank bus bars to the main distribution bus bars. The total run one-way from the distribution bars to the battery...

    Connecting Solar Assistant to EG4 Lifepower batteries

    I have a pair of EG4-3000EHV inverters setup in split-phase and a bank of 6 EG4 Lifepower4 v1 (as far as I know; purchased in mid-2022) batteries. I have closed-loop (RS-485) communication running between the inverters and batteries. Solar Assistant is working great for the inverters, and...

    How much of a panel can go unsupported

    I'm working on engineering my "ground" mount for a rack of Bluesun 460w bifacial panels. Due to the place I'm planning to put the array, at least some of it would need to overhang a different roof. I estimate I'd have at least 25% of the length of the panel unsupported. I don't think that will...

    EG4 3000 inverters in mixed on/eco mode

    In a system of, say 4 EG4 3000EHV-48 inverters setup in split phase (2 per leg) is it possible to have a mixed configuration where 1 inverter on each leg is set in the on/active mode, while the other 2 set in eco mode? The goal would be to reduce the parasitic standby load of the additional...

    Flat/Angled mounting of EG4 3000EHV-48 inverter

    I have a pair of EG4 3000EHV-48 inverters. However, with my available wall-space and the clearance specified in the manual for airflow/cooling, I'm having trouble cramming them on the wall, much less potentially adding 2 more to move more of my load to solar in the future. In the manual, I...

    Recovering from poor purchase decisions

    I feel like I made some generic beginners mistakes, and now I'm trying to figure out how to make the best of what I have. I'm seeking to build up an off-grid solar setup capable of powering a shed and an RV with 50-amp service. Now, from the get-go, I know that what I purchased isn't remotely...
