Dual module(so I can move the beast) compressed (squeeze box). This one will be on a rolling bace and enclosed with a differential thermostat controled cooling fan. Air is only circulated if the air is cooler than the cells and if needed. The voltage and current will slowly increase and the JK...

I was watching Madi on Digital Mermaid assemble some flexible buss (jumpers), four #8AWG I believe and noticed how low the resistance readings were. This had me confused because I had bigger a cable and my reading were higher. Could tinned cable make the difference? YES!!!!!! My test...

Everything’s working better than can be hoped for and the system is virtually running autonomously. I’m looking towards the future and one can never have too much battery. Just bought 16 cells with flexible busses, JK bms, fast blow fuse & holder, die spring for compression and already have all...

Commissioned my third battery build and like always a little drama. The batteries arrived from Eel batteries in 4 days and 4 of the sixteen cells were damaged. They were dropped upside down and the 2 bolt terminals were bent almost touching the case and others were dented by an nimrod that...

Several years ago I got fed up with over priced cable with poor quality service and found a deal with T-Mobile high speed home internet. At $50 a month and no data caps it was a deal. It worked fine for a few years but others found out about it and it started to slow down to crawl 20Mbps or much...

I manually disconnected from the grid to protect my system. A year or so ago when the wind blew hard I noticed voltage spikes, probably from lines slapping together. That time one inverter went into fault with no codes available, my assumption was it wasn’t happy about the weird supply. I was...

The end game is as little system interaction as possible. And I’m getting close. The goal is to use the grid as little as possible and only during off peak rates as needed to supplement solar if insufficient because of weather or high demand. Also maintain optimal state of charge for emergency...

A friend asked me to drop by and have a look at his system because he’s having some problems. The guy is highly intelligent so I’m ASS-U-ME-ing that he knows what he’s doing. Well, upon entering his equipment room I was so taken aback that it must have shown on my face because he looked at me...

Alright, it’s not as dramatic as meltdown of a T class fuse holder but more of a track down nuisance that I want to bring to light. Some months back I ran into a Solar Assistant and and a shunt issue. They would error or momentarily fail. They had separate sources but had one thing in common...

I wish I had this a long time ago. I found an app called “Sunnytrack” that lets you can stand where you plan to put your panels and view through the phone the suns path at current day or at any point in time during the year. It shows the arc/path across the sky for winter and summer solstice. It...

We’ve been experiencing a heat wave and I’ve been watching the internal temperature in the inverters closely. I’ve seen them get close to 70c. The line/loads and PV currents to each are well balanced and as such the temperature of each inverter are very close. Today I decided to clean the...

There’s some weirdness building and global tensions so it might be a good time to get what you need now. I’m considering buying an extra inverter but buying a pair deal thats actually is still cheaper than one 280ah battery. Tier one inverters are so cheap that for intensive purposes…disposable...

First there were heat pump HVAC then water heaters, dryers, now……… Da…Da,Dahh! Pool heaters! Learning something every day. Gets some more solar panels boys and girls, we’re gonna need them ?

I was shocked(astonished ?) by the looseness of a number of my cell terminal nuts even though I had re-torque them days after the original assembly. Three different 16s batteries but two had similarities and similar issues. None of the batteries had any electrical issues(yet), beautiful balance...

I’ve been running of 6 months with a 2P configuration with great success except for the 300 Daly’s current sense has gone nuts. It can swing 2X actual current and back again(see screen grab). This has lead me to adjust the bms’s settings higher than I like since it wants to trigger a false over...

It’s been working great for three months and now it can’t connect. Everything else on my network never lost connection, streaming or cloud apps. Restarted the SA, router, iPhone… nada. Went off of Wi-Fi and to the beginning with Bluetooth setup and I can see it’s connected to BT but it refuses...

I’ve been using “Willy Weather” App for may years for figuring out how the weather would be for wind when I was boating. The last few years I’ve also been using it for solar. Select the UV at the bottom and you’ll see three days into the future. It’s been amazingly accurate for solar energy.

I’m kinda curious what different inverter’s sine waves look like and what your grid looks like. The first picture is twin, first generation, MPP LV 6548 (247 volt) low load. The second picture is with 6000 watt load (clothes dryer 246 volts) and the last is grid. Between line and neutral didn’t...

I’m reasonably satisfied with my JK’s…now. I thought I had a problem because my third battery commissioning went a little rougher than the first two JK’s. Something was definitely different with the third and newest bms. The first thing that popped up was the yellow flashing “Change password in...

I’m retiring my 2P busses/jumpers (32 cells) and going back to a diagonal #2 cables jumpers for 2 banks. The 2P jumpers I’ve been using 1” wide braid, 4 ply, fixture soldered and the contact area was embossed with 10,000 pounds of force( see photo). Despite this effort, it required regular...

Today is a cloudy day with some rain but something weird happened. The clouds thinned out and let the sun poke through in places. When that happened I could hear the inverter fans start to whine. Then I heard a pitch I never heard before and glanced at the Watts and was confused by what I saw...

I’m planning on mounting JK 200amp versions on the end of a 16S wooden battery boxes. For ease of connection, supplied balance wire length and seeing status light, I’m orienting it connector end up (FET end down). The bms would be spaced off the box about 3/16” by the use of four 1” square 3M...

I heard of mosfets getting fused closed. It’s been a long time since any of my batteries have been triggered, since they were commissioned. Would it be a good idea to test each bms? Could I just turn off the charge state in each bms in my battery bank one at a time and note if the current at...

I had a 2P-16S that used one Daly bms that was giving me trouble so I elected to split bank in two and use two JK’s. Brought them down to 20% SOC and rearranged them. JK’s were flawless in setup and operation but my problems started when I got the cells above 3.4 volts. The balance went crazy...

I have several Neey clones that work great but can’t shut them off at a pre determined voltage and reasonable back on voltage (voltage spread too great). I know the newer ones can when using the android app. The only way to turn it on or off is through the iOS app which isn’t going to work. I...

I found one online a year and a half ago, now I just can’t find it. You enter in the number of wires and size and it told you what size crimp lug you need. I’ve spent an hour on different search engines and every kind/ combination of wording using the + trick or “ “ trick and nada. It’s like...

Anyone on the new stable yet? I’ll wait a bit myself. If anyone is a gremlin catcher, it’s me🥴

When charging from the grid, the inverters charge to bulk setting(56v), slows gradually as it nears setting, hold voltage/absorbs for a short time, releases and the voltage settles to the float voltage(53.6v). All fine right? Yet when the solar charges, it goes to the bulk voltage setting(56v or...

It was driving me crazy trying to get Solar Assistant to connect to two JK bms’s. Every port combination/option, every plug in the usb power hub, every port in the pie, no joy. Then I remembered that I’d ordered extras modules and adapters. Tried another one. Bingo! Instant success! Order one...

When I connect them to my inverter LV6548 (network port with monitor symbol), the molded body of the other un connected end (USB) gets hot quickly., like within a few minutes too hot to touch. It does function when connected to a device perfectly but it’ll dripping plastic and probably hurts...
