I am trying to understand whether I could still use generator power if I remove the 48V batteries from the site and the inverter is off. The generator power is wired thru the Inverter. Would the inverter still "wake-up" and pass-thru the generator power, even if no batteries are connected to the...

I am trying to understand whether I can connect my newly installed EGC (solar racking ground, charger controller ground and inverter ground) to the existing AC grounding that currently serves the cabin OR if I need to install a new grounding rod system. This is for an off-grid installation...

This is for an off-grid 15 KWh 48V battery bank (3x EG4s) connected to a Schneider 4048 Inverter in split-phase. The system has been running well for over a year. I would like to get feedback on how you'd deal with these warnings if you were running this system. I have a total of (3) alarm and...

Doing research on the Outback FLEXmax 100 with Arc Fault protection but not sure about lithium/EG4 battery compatibilities. Anyone using the FLEXmax100 with EG4 batteries? Any issues with compatibility?

Here is my final design for my off-grid cabin PV installation. I would appreciate any last minute feedback or blessings from the group: I am comfortable with most of the design but a bit reluctant about the DC disconnect switch rated at 32A. I think I should've bought a higher current...

I guess I don't exactly know what the "poles" are hence my confusion trying to select the correct DC switch for my setup. I have (1) set of 8 AWG wires going to the DC switch. The wires carry 2 x Isc: 13.85A = 27.7A so in my limited understanding of things I would expect that I need 2-Pole @...

This week I've received the solar panels & racking mounting rails + hardware. MPPT is also under way. I am shooting for installation the following weekend. I have some last minute questions that I could use some help with: 1. 3/4" Schedule 80 PVC Conduit to run a a pair of 8 AWG + ground...

I am struggling finalizing the PV package for my off-grid cabin and could use some help. One package seems to be border line oversized risking high voltage on the MPPT and if I upgrade package sizing, adding two more panels and upsizing MPPT I then risk being too low on minimum required MPPT...

Anyone with PV Solar Farm design experience? Looking for some basic industry-quality assumptions so that I can create a class case study. Looking to answer some of these questions: panels/acre? Power capacity/Acre? Estimated energy production/Acre? Average $/kWh ? Average $/RECs? TIA!

Selling (4) new, unused Q-CELLS-Q.PEAK-DUO-L-G7 405W panels. $1,000 for the package delivered 1 hour of Norwich, NY.

Got a clamp meter and went happily to measure the output current out of my 240V generator and this is what I got: - RED: 11.77A - BLACK: 11.87A - WHITE: 6.86A Is this as expected? I just don't understand why the neutral line would 6.86A and not 22A. Could someone please explain me the...

What is the importance of differentiating the wire with a MC4 connector on an end and calling it "PV" as opposed to THWN electrical wires without the MC4 connectors? I am in this rabbit hole trying to understand WHY this is important but no success. Could someone briefly clarify the terms and...

Here is the (12) panel design I am working with, two parallel strings of (6) panels in series each. Panels to be Canadian Solar HiKu6 400W @ 108 cells connected to a Victron 250/70 MPPT & 48V battery bank with 15 kWh capacity. I have a few lingering questions that I could use some help of...

My current system is a 48V Conext SW4048 inverter with 15 kWh energy storage. I need to install (2) distinct solar arrays on my roof, one with (6) panels and the other with (5) panels, different panel quantities and different panel orientation. The Conext Charger Controller MPPT 80 600 seems...

We decided to also add an PV array on the smaller roof area with a better solar exposure. The only issue we have is the roof area limitation: 42 ft by 8 ft, which seems tight for a PV array. Ideally I would get more panels if I were able to mount them portrait orientation. Not sure if possible...

I purchased directly from EcoFlow last year a River Pro 720 Wh unit which I use to run my mini fridge in my cabin. Originally I was able to run the fridge for over 30 hours. After a few months I realized I was getting about half of the runtime. This prompted me to purchase a Wattmeter. Not to my...

Hello @JacksonSolar & @SignatureSolarJames & @Markus_SignatureSolar I have a running setup with a Schneider SW Inverter + InsighHome + (1) EG4 Battery. Setup was properly connected to InsightHome and correctly showing EG4 BMS device: Yesterday we received (2) more EG4 batteries straight...

Here is my current setup: (3) EG4 48V Batteries (2) Victron Busbar 4P 250A (1) 400Lbs 12U Server Rack - I am ordering (2) sets (black/red) of 3 wires same length, busbar to each battery - I am also ordering (1) pair of black/red wires, same length, inverter to busbar I suspect aside from the...

100Ah 48V EG4. Initially at 87% SOC connected to a 8A 48V battery charger (fig1): EG4 BMS reads out 100% SOC but still charging @ 8.2A with battery at 54.95V (fig 2): Battery at 100%, zero current and battery at 53.70V. Few cells reading as "(Bal) 3.356V". (fig 3): I am basically trying...

I am currently running my off-grid cabin with (1) EG4 48V battery. This year I need to add at least 1 or 2 battery racks to my system. The only issue I had last winter was the cold weather limitation in which I had to wait until mid-day to charge my EG4. I was recommended Trophy rack batteries...

I am looking for recommendations for 48V battery chargers to top balance LFP rack batteries? I intend to use this charger with shore AC-grid power. Thanks in advance!

I am trying to wrap my head around the dynamics between a lithium rack-type battery with internal BMS and a inverter charger which has NO communication with the battery BMS. Who dictates the charging current to feed the battery? The battery BMS or the inverter charger? I ask this because I...

This is my roof and the proposed layout for a total of (12) Panel to be wired in a 6S2P configuration for a total of 4,860W installed PV capacity. I tried to position the panels so that one could still safely move around the roof to clean up gutters and the chimney. I would like to get...

I've read a few posts about charging current and it seems like most commonly recommendation is around 0.2C to 0.5C. Could someone point me to a brief explanation on how this is determined? I would like to understand the science behind this. And more specifically, what should be the optimum...

I currently have a 1-1/2" electrical conduit running to the cabin from the shed, underground, with split-phase AC power and a generator signal (control) wire inside the conduit. I need to run 8 AWG wire from the roof to the shed. Can the new PV DC wiring run inside the same conduit with the AC...

I have an operational split-phase system based on a Kohler 12kW Gas Generator coupled to a Schneider Conext SW4048 + 48V 100Ah battery. I have noticed thru the Conext control panel that occasionally the generator is outputting only one of the hot wires properly - so instead of getting...

I have an operational energy system with a Schneider SW4048 inverter coupled to a generator, thanks for all the help from some forum members. With the inverter+battery operating, it is time to move on to the PV + MPPT installation and I could use some help here too. I currently have (4) Q.Cell...

My current setup is the following: - Conext SW4048 - Conext InsightHome - Conext AGS - EG4 48V 100AH - 14kW Kohler Generator, split phase, 70A breaker Installation has been completed and in operation BUT I can't figure out ideal Conext device settings. From the EG4 battery specs sheet I have...

I currently have (1) EG4 battery and I am looking to add a second EG4 battery to my system. The vendor recommended the following: I would like to follow this recommendation but I am not sure how to "purchase" and "add" a common busbar to my battery. Could someone explain how this is done and...

Just realized some of our 240V loads were not powering up correctly and when I went to check the EP only one of the hot legs in our 240V split phase panel was getting voltage. I then went to the generator to measure voltage at the generator output and confirmed only one of the generator lines...

After reading the Schneider Conext SW 4048 manual I was not able to determine whether it would work with my EG-4 LifePower4 Lithium battery. It raised me concerns since the product literature does not mention lithium batteries at all. Could someone clarify why this inverter, as well as the...

This has just been a very disappointing experience, considering that I specifically chose the vendor based on their sales and technical support claims. Yes, the fact that they have members actively participating in these forums also led me to believe that they would stand behind their products...

I am confident doing the calcs for a device running continuously but i suspect things change when you add cycles and surge power. Could someone help me calculate the estimated runtime with a 720 Wh capacity battery? This is for a refrigerator which cycles and performs as follows: - It takes...

I need to replace my generator battery - it has been abused and acting up, not holding charge. Could someone recommend a vendor (Lowes? Walmart? Electrical Supplier? Autozone?) and a battery brand for this application? I suspect this is a size 51 battery? Am I reading the labels correctly...

Very exciting, I believe I am making (slow) progress with my installation. I have been able to connect Generator to Inverter + Inverter to AC Subpanel. Yeah!!Everything is working so far: the inverter is reading the 240V from generator correctly and I am getting the correct 240V out in the...
