How does one handle properly wiring large gauge PV wire to an CC that has smaller connections? Scenario : 6x Panels @ 37.07v/13.79a Distance from Panels to CC: 100ft EG4 6000EX : PV Connection unspecified (assuming <= 8AWG) * Not provided in the manual At this distance, running 15a at 100'...

I had one of my Eve cells start leaking. Figured I would check here before searching online.

Just picked up 2 SK48V100NC batteries from SOK and upon mounting and precharging, the voltage is 40v out of the box. Isn't this a little low for new lifepo4 batteries?

I'm trying to understand why configuring a system to take advantage of the optimal output and availability of equipment and power isn't talked about very much. I do understand that finances are a challenge in some cases along with the need for split phase but there is a happy medium that has a...

I'm looking to do an off-grid installation that requires a split phase setup and have been looking at the eg4 8K all-in-one charge controller. In Wills videos I believe he said that it seems to work fine in off grid mode but it's the on-grid features that are an issue. I'm wondering if anyone...

Has anyone encountered this issue and how did they resolve it? I recently purchased a lv6548 second hand. When I go to register an account for wifi connectivity it tells me I cannot because the device is already registered.

I'm setting up a lv6548 and noticed in the docs (attached) that it's recommended detailed example provided would exceed the max voltage rating in a 6S configuration when temps dip below 50°F. Am I wrong or misunderstanding something here? Taking temperature coefficient into consideration I...

It's been a out 4 months now since my 3000w wzrelb inverter blew up and think I finally have enough in the budget to replace it. I did use the 3000w so 5000 would be a better fit if possible. Any recommendations would be great. I even noticed a refurbished growatt 6000 that was about $900. The...

Was thinking about adding a large buck converter to add redundancy in the case where the 48v inverter fails and my only option is local 12v resources. I came across this beast of a converter and was curious what other's thought about it. Tian Power DCDC 175A 2500W 48V to 12V Buck Converter and...

I ran the numbers to calculate the max output from the 2 panels i have and would like to pair with a SmartSolar 100/20 (48v config). I chased down the coldest day recorded in history for my area (hit these temps twice a long long time ago) and it put me at the the max output of...

Have a modular build I am doing for a client. In my past projects I've built my lifepo4 batteries but it appears that there are some options out there that really compete with the cost of the DIY build. I am looking for suggestions/recommendations for pre built battery banks that play well with...

I've seen examples of how to appropriately wire 4 to charge and discharge evenly but for some reason 10 batteries breaks my head lol. Can someone please assist.

Is there a safe maximum % of voltage drop between PV and CC using the wire without long term degridation? This is what I am wanting to do. I am wanting to connect the following together: 1 - Victron SmartSolar 150/35 12 - 4S3P PV's each rated max 41V/11A This would give max output of 164V/33A...

So my 16 LifePO4 cells are stacked on there side in 2 vertical columns because of space requirements. My question is, since the coldest cell in my bank is closest to the floor, can I connect the victron SmartShunt Temp Sensor to the lowest positive cell terminal in the stack (cell 8 so that I...

I've finally been able to pull the cells out I bought last year out of storage and build my battery banks. My concern is that there is a difference between cells. None have been hooked up and the only exposure they have had has been seasonal temp changes. Each cell is 305ah and all showing...

I'm really wanting my 48v pack to be all together and space is forcing me into 2 columns of 8. I will be laying them on there side, with 2 columns of 8. Compression will be maintained only by threaded rod at the top, middle, and bottom, on the outside of the columns (not in between) using 2 -...

I'm needing to order the primary inverter for my offgrid home. Below is how everything is setup currently. Can I please get recommendations for some reliable efficient ones from the community. I know we are looking for at least 5kw and trying to decide on either putting small tankless water...

I'm trying to understand what causes a panel to reach conditions that push it to VOpen or CMax levels. Can someone please explain?

I was looking back at my purchase of cells and bms and not sure if it was a good deal or not. Can I get others opinions? Total Cost: $4,666.00 32 Eve Grade A 304ah Lifepo4 Cells 32 bus bars 64 studs & nuts 2 Daly 48v 16s 300a Smart BMS w/Bluetooth

So I have my 32 304ah cells (2 banks of 16), the hardware they sent with the cells (nuts, studs, and bars@90*20*2mm), and I have my 2 Daly 48v/300a BMS. Are these bars enough to supply the 300a max draw on the cells without significant resistance? Does each bus bar going from cell to cell need...

I have 4 SmartSolar 100/20 CC that I need to bring together in a power distribution block that will tie to another PDB that my 2 48v LifePo4 battery banks and inverter will connect to. Each bank is using a daly BMS that is rated for max draw of 300a. If my calculations are correct does this mean...

I searched for a deep dive into the pros and cons of each in an offgrid setting but found very little. Hopefully this will fill the gap. Here are some of the questions I have. * Is the output of microinverters pure sine wave? * Can microinverters produce 120/240 (split phase) without additional...

I thought I bought the right items but now I'm lost on how to wire properly. I have 32 New Eve 304ah LifePo4 Cells and 2 Daly 16s 300a 48v Smart BMS w/ Bluetooth. I was thinking that I need 2 16s BMS's for creating 2 banks of 16 for my 48v build. Now I'm lost on how to wire and setup. Any help...

Can someone help me understand how to determine if a fuse/breaker is needed for 1-9, how to determine the size of the fuse/breaker, and if possible explain why at that location Understandings (please correct me if I'm wrong): * DC (Direct Current) power flows in a loop. * Because DC requires a...
