When looking at my setting for an issue I had with my Sol-Ark 15K, the tech commented that I'm charging my batteries at full current right up to full charge. I've looked at my settings on my Seplos BMS, I don't understand which is the parameter to change that. I already know that I'm going to...

After reading 20 pages of "house burned down", I'm not as secure about having my batteries in my living space as I would like to be. Fire inspector said the cause was a fuse arcing after blowing, I say that it more likely the probable cause, not definitive. I have class T fuses on each battery...

After reading some threads about battery issues, I started to think about cell spacing, as too much compression can cause cell damage. The data sheet for the Eve MB30, which is in the resource area, refers to this. "Customer shall fully consider the influence of the cell swelling force when...

This looks like it's a Seplos BMS. The numbers on the screen certainly match my screen. Anyone purchase one of these? I have 3 DIY with seplos V2, looking to build 3 more. Could save $200 on 3 if they are the same thing.

I've got 3 304ah batteries with Seplos V2 BMSs (passive balancing) below my inverter. They run individually to a busbar, then using both breakers in my Sol-Ark 15k to connect the inverter to the busbar. The 3 batteries are connect via comms, and the master battery connected to the inverter...

Noticed my fans are running a lot, so looked at my temperature via SA. Shows it holds between 144 and 145.5 F. Anyone with a 15k, what are you seeing?

Fisker is slashing their prices nearly in half on their top model, over 35% on their lower end to avoid going under. Check this out

As you can see from the picture, when I get over 5kW of draw, grid kicks in. It's not a hard 5kW, as sometimes the battery will provide around 5500W. I must have something set wrong, but not finding it.

Anyone else not getting info from their Sol-Ark through powerview? Solar Assistant is working, but powerview doesn't show data for me since around 9AM. There was an update today, maybe they broke it?

EG4 has an abbreviation chart in their Chargeverter manual, thought it might be helpful.

In my area of western NY, we received a postcard with exciting news, our smart meter is coming. We contacted them to let them know we are opting out. They will gladly do that for a "small fee" of $11 something a month. That got me wondering about if people fought the fee. Doing some research, I...

I had a Generac 10k LP generator attached to my house before installing solar. Removed it during full remodel of the house. I'm going back and forth between AC coupling and the generator, as I don't see how to have both. One of the considerations is transfer time for the generator. In it's...

I've got 3 Seplos 10E with BM2. Running version 2.1.8. Everything works. They are all connected to each other via RS485. Bluetooth works with all 3 batteries. But, with battery monitor, I can't see the first battery (Pack 00) I can see the second and third batteries (Packs 01 and 02) There is no...

Adding a third battery to my Sol-Ark 15K. This means moving cables to a busbar, which means I need to take my batteries off line. I can't find a way to tell the inverter that I don't have batteries. I checked "no battery", which is how I ran it for the first month before adding a battery, but...

Setup is a Sol-Ark 15K fed directly from meter (with disconnect in between). I have the whole house on load. Because of this, I don't always notice when grid is down. They make simple devices that will alert you when power is out, but obviously they won't work on a normal outlet. So, I'd like to...

Wishing everyone a very merry Christmas and an amazing new year. This was a great year for me, in that I took the plunge into solar and came out with success thanks mostly to this site (Thanks Will) and the amazing people on here who constantly offer help.

Pretty sure I read discussion about this, but not finding the thread. I have 2 DIY batteries with Seplos 200A V2 BMS, closed loop. I'm seeing about 200 watts of drain when not in sell mode. I never really noticed this at first because they were always charging back up, but now with some really...

Last night we had an outage for about an hour and then 2 short 1 minute ones shortly after the first was restored. The only way I noticed the first time was because the lights flickered when the heat pump furnace came on. Are any of you using a separate app/devise to get outage notifications...

I have a ditch dug to get wiring from my panels to my house. I MAY in the future add more panels in the same area, so thinking about burying the conduit for this possible additional array next to the the existing conduit to save work/possible damage in the future. The additional array would be...

Sol-Ark 15K, connected directly to the grid. I'll have 19.1kW of DC PV connected when done. I have a 10K generator that came with the house that I was going to connect to gen in, but as I add batteries, I'm looking at using the gen in for AC PV instead. I believe from what the manual says is...

I've had my first of 3 sets of 14 panels on my house for about half a year. Finally got around to putting up my second set. We live in basically a holler, so raising the ground panels was the goal. Decided to make a lean-to to accomplish this. Used the same Unirac mounting that I used on the...

Reading the instructions for form IT-255 for the 25% tax credit, it appears that off grid/non-sellback folks don't qualify? Anyone from NY find a way around this? NY Tax credit form "If the solar energy system equipment produces electricity, you must enter into a net energy metering contract...

I'm building a 48V battery in 4 segments. This is so that I can disassemble it to move it from the house inverter to my camper inverter when I go camping. I need metal boxes that are 8 X 8 X 16 for each segment. These boxes will be stacked on top of each other, so the boxes need to either have...

Building a free standing lean-to to mount some of my solar panels on. This will have a perimeter of 8 X 24 feet, 8 posts in all. Posts are 6x6 pressure treated ground contact rated. I'm in western NY, soil has some clay, though that's hit and miss. I've read quite a bit looking for the best way...

I've had a few instances where I lost power or partial power. Two of those times, it appeared to be brownouts. Of those two times, one of the brownouts went to outage and the inverter (Sol-Ark 15k) eventually went to battery, but only after a very noticeable amount of light flickering. The...

Built 2 48v batteries with Seplos 200a bms. Both batteries will charge and discharge fine. Both batteries will be balanced within 5-10 mv when discharged to 20%, one battery will charge within 15mv or so before balancing, but the other is usually off by over 50 mv. The bms will balance it...

Sol-Ark 15, two batteries with 200 amp Seplos bms. Played around with some of the Seplos settings. At some point, the settings in the BMS app changed my Sol-Ark charge settings. For Float, I'm trying to set 55.7v as per the latest example in the Sol-Ark manual. It takes the setting, but then...

Just installed second battery to my Sol-Ark 15K after having one battery connected for a couple weeks. Batteries are connected one to each breaker. I have closed loop, and I can see both Seplos bms on the computer. Does the Sol-Ark just treat these as one battery? Can the inverter see both...

Sorry the pictures are blurry, my phone just sucks. This is a standup case with 16 304ah cells. Cabinet is a knockoff of Vevor 16 X 24 X 12 deep. Seplos 200a bms, 300a T-class fuse, and BEP Marinco disconnect, which has been confirmed safe to use on a 48V system. Not in the pictures is...

In April, I ordered 32 Cat302ah cells from DIYPOW. At the time, there was quite a bit on the forum about people not being happy with purchases from a couple of the common suppliers. So, I decided to shop around. I had put the cells in my cart for DIYPOW, and left them there. The next day, I had...

Built my first battery, took forever to top charge, but it got there. Part of the issue other than it just takes a long time with these little power supplies is that it wasn't staying on CC. So, I took advice from here and installed heavy wires and crimped on eyelets before starting my second...

Sol-Ark 15k with Seplos BMS My understanding is that I am supposed to let the battery drain the first time to let the bms learn the full range of the battery. The only way I can understand to do this is to be off grid with no PV. How low do I let it go? To my normal minimum charge, or till it...

Just want to verify with anyone who has a Sol-Ark15K and Seplos. Connected my battery. I can run off battery with grid disconnected and solar off. I believe I have closed loop, as the below screen updates in sync with the seplos software, and the triangle with an ! inside of it under the battery...

I must be missing something. I can't find any instructions on how to actually set the BMS up. I built my battery. Turned on the BMS and it gets to a flashing green led next to the dip switches. Screen lights, but nothing on it. Reads 57.1 volts at the terminals. I loaded the software. Doesn't...

Very confused about who makes batteries. I ordered batteries from China. Will do a write up of the company I ordered from in the next few days. But, I ordered CatL batteries, but they were back ordered, so they asked If I would be OK with Eve. I said yes. Got the batteries, they came with an...
