Thanks for the detailed replies, RCinFLA and pvgirl! Just what I needed to know. :)

Thanks for the reply. I am off grid and will not supply anything on the AC input side, all power will come from batteries. I was looking at page 18 of this PDF that describes maximum AC output amps of the 5kva model...

I've just purchased a Victron Multiplus II 5000kva 48v 120v inverter to replace a failed Growatt. The Victron manual calls for 2 AWG on the AC output side. I'm quite comfortable and familiar with DC cabling, but am a bit lost when it comes to AC. I've looked all over for a 3 conductor 2 AWG...

Thank you. I just checked and confirmed the second inverter is floating, there is no continuity between N and G on the AC output (48v growatt 3000 TL LVM’s). I’m seeing ~55v on the second inverters neutral line, where as the first inverter (which is grounded to earth) shows 0v between N and G...

Sorry, I don’t quite follow. Are you saying to break the N / G bond on the first inverters panel and only have it on the second AC panel? Or are you saying to N / G bond on both AC panels? Just to confirm, the systems are completely separate on the AC side and as far as I’m aware there is no N...

I have a bit of a strange setup and after lots of searching have been unable to find an answer on how to properly ground my systems. I am completely off grid, and have two inverters that each have their own separate AC panels. One inverter is always on and powers the majority of the house...

Based on a few months of use now, and lots of monitoring, I’m fairly certain these issues are simply a matter of the BMS incorrectly reporting the SOC. Background - I have 3 of the 105ah 48v EVE batteries in my bank along with a couple other LFP batteries I bought a few years ago. I’ve been...

Sorry to resurrect this thread, but thought I'd provide an update for anyone else that has a fan failure. I opened the case and confirmed it's an 80mm fan with a 4 pin connector. However, the tabs and size of the connector are non-standard. I tried using a typical 4 pin computer fan and it...

This featured worked for me for at least a few weeks to a month after release. However, now it's the same as what you're reporting, it does not seem to store trend data once the app is closed. I've seen several more beta releases since it stopped working and it has not brought historical trends...

One of the fans on my Growatt 3000TL LVM seems to have failed and I'm seeing an error code 001 which corresponds to fan failure. I'd like to replace it with either a stock Growatt fan of the same model or any other off the shelf fan that would be compatible with the inverter and not throw...

After downloading the app, there are two firmware updates that the app will initiate to enable these features. I have almost 24 hours tracked now, so far so good!

Just wanted to share this exciting news for any other Victron smart shunt battery monitor owners. I've been anxiously hoping for this feature for the last year and it's finally available in their beta release of the app. Long story short, every time you closed the app or disconnected from the...

I don't think that's necessary. I don't see any mention of an additional breaker between the AC output and subpanel within the manual (pages 5-6) https://www.ginverter.com/upload/file/contents/2019/06/5d0355a465ff4.pdf Just be sure to size your wiring correctly (6AWG) between the inverter and...

Haha, yep, I went deep down the youtube rabbit hole on water generators. I saw a guy essentially diverting an entire river worth of water for a measly 500 watts. They look like fun to build, but decided they would only really make sense if you lived in a cave with no access to the sun.

Haha, that’s a pretty good idea, might have to read into it.

Yes I’ll likely use more than 10% in the future with a large home theater system, additional lights and computers, and a large freezer. I’m completely off grid and so I sized the bank to be both future proof and something to get me through multiple cloudy / rainy days. I’m on the wet side of...

Good distinction regarding sitting vs. cycling. So even though I'm cycling near 100% would it be better to keep that cycling in the 20-80% range for longevity? I'm using a Victron smart shunt to assess SOC, but also cross checking on the batteries which have a basic built in diode that reads in...

I have an oversized LIFEPO4 battery bank and oversized panel array. In typical use I'm only depleting ~10% of the bank's power overnight and am fully charged by just 10-11am. This means the batteries are sitting near 100% SOC for the majority of the day. Should I be concerned about potential...

Not yet, sorry. I also noticed that note in the manual after first posting but for my current needs I’m getting by without splitting loads. I’ll likely revisit this in the next few weeks and will post here if I have any luck.

Thanks for the quick reply. It’s a good quality bus bar, 500a blue sea system, and cabling is all equal in length and vastly oversized in AWG so minimal losses there. Anyway, sounds like I can stop second guessing myself. Appreciate the relief your answer has provided.

I have 3 parallel banks of batteries, each one connected to its own terminal on a 4 terminal bus bar. The main load is connected on the last terminal of this bus bar. Is it reasonable to expect even draw from each battery bank even though technically some batteries are wired closer to the load...

I've just finished a test setup using 2 growatt 3000tl LVM 48v all in one systems. I don't see any explanation on the functionality when wiring these two systems for parallel single phase operation. My assumption was that the AC load would be split between the systems in this configuration, but...

Thanks for the feedback. I've taken your advice, adding in fuses for each series on the UT1300's. Here's a first pass at a schematic if that helps others visualize (I know it's helped me a ton). One of my other concerns with the build is voltage drop on the panel array during cloudy days...

First time system and jumping in with both feet. As the title indicates, I have 12 Lion Energy UT1300’s that I’ll be wiring in series parallel @ 48v, s4p3. I have lots of questions, but for now my focus is BMS requirements. The individual batteries have a built in BMS, but am I right to think...

Thanks for the quick reply, will take your advice and start a new thread. To answer your question about use, I’m building a 100% off grid home in rainy Hawaii. I’m overbuilding the capacity to account for extended days without sunshine and know that it’s not wise to add additional batteries to...

I jumped on this deal and am planning to configure 12 of them in an s4p3 configuration to get 48v. While the batteries individually have BMS’s do I need a BMS for each series as well? Any concern about individual batteries coming out of balance with the rest of the array? Any advice is...
