Does anyone have a copy of Build 2023-08-16 lurking on their hard drive you could send me? I did the last update thinking I would just reinstall the last stable version if I didn't work out, I thought for sure I had saved it on my computer but apparently did not. After many emails with Duane...

This popped up on my Amazon feed today 3/22/24. Limited-time deal: 60A MPPT Solar Charge Controller 12V 24V 36V 48V Auto Battery Regulator, Solar Panel Max 150V Input for Lithium, Sealed, Gel, and Flooded Batteries (Yellow) https://a.co/d/elcOd9P

I have used Alison online courses for several years now in both my professional and personal life. I'm in no way affiliated with Alison but wanted to pass on the availability of this online course that may be of interest to some. The structure of the training is self paced and relevant. The...

Picked up a new drone, so of course I needed to get a shot of the current PV installed.

Meaningless post to push my total to 1000 posts 🥳

This is my third and final ;) DIY battery revision, the first two were contained in a metal truck toolbox. Went a different route here to repurpose my old Power Conversion (Eaton) lead battery rack and distribution panel. The bus bars are rated at 600 amps, spaced and supported on fiberglass...

Was rebuilding one of my packs today, changed the layout from a linear string to a square. Attached the lead of an Overkill BMS for battery 1 to battery 16. Of course the magic smoke was released... Dumb mistake because I was in a hurry and distracted. Nobody to blame but myself, but I'm...

This story is a little long, but the problem was quite involved. I bought a new Growatt SPF 12000 at the end of last year and it's been sitting in the garage, still in the crate. Just got around to hanging it on the wall this week, that was a significant chore and I was glad to have it done...

Just reinstalled Solar Assistant on what's claimed as a High Endurance SD card. The latest beta version allows saving historical data and uploading it to the new card so you don't lose anything. Putting this out there as a date reference of how long it lasts.

I have received 32 EVE 230 Ah cells from Docan's Houston TX stock and 31 look pristine. They all measure 3.293 volts out of the box. Number 32 is only reading 3.286 volts and also appears to have a defective weld on one side of the negative terminal. The square tab with the stud has a stepped...

These fires are killing my production! I'm in south central Pennsylvania.

Finally finished my upgrade build. Had one set of EVE 230's mounted in a small wall mounted toolbox. Was going to duplicate that with a second set of the same batteries but decided to do something different. I now have two batteries in a 48" toolbox and put a set of wheels on the bottom so...

I currently have two batteries assembled with EVE 230ah cells, each with their own Overkill Solar BMS. They work well but as the Overkill BMS has no communications port, the Growatt 6k AIO they feed has to "guess" the SOC based on voltage. I see Trophy Battery has a battery using the same...

My SPF 6000T DVM generally works well but I've been having a problem where the setting for the constant voltage charge point resets itself to the default value of 56.4 volts. None of the other settings change, just the CV. I don't have enough PV or battery capacity to go totally off grid so...

Playing with the thermal camera, got a surprise when I looked at the 200 amp breaker which was carrying about 20 amps. It's cold in the garage so don't give a lot of thought to the actual temperature reading.

For sale is a Cotek SK1500-124 Pure Sine wave 1500 watt 24 volt Inverter in pristine condition. I used this inverter as a UPS and it had no trouble with a refrigerator, large upright freezer, the television and a few LED lights. Asking $180 includes shipping conus and PayPal fee...

I have recently installed 10 Q Cell 335 watt 72 cell panels in a 2s5p configuration. A local guy is selling Boviet 325 watt 72 cell panels and I'm thinking of adding two more as a sith string. I don't believe the specs of the two are different enough to cause any problems but wanted a second...

Finished my ground mount over the weekend. Wood frame construction with Uni-strut to attach ten 335 watt panels in a 2s 5p configuration. Sized appropriately for a Growatt 6000 watt non MVP model. My only regret is not getting two more panels and finding another place for the satellite dish LOL.

My grid tie system with 29 panels has had its third Solar Edge optimizer failure in about 4 years of operation. I don't know if a 10% failure rate is considered normal but I'm sure glad it's under warranty.

Decommissioning my old lead system, so up for sale is a Battery Extra EX02 12-48-400 desulfator. I had it rack mounted in my home, so it's never been exposed to moisture or dirt. Below is a link to the manufacturers web page. Works on lead acid batteries from 12 to 48 volts, up to 1500 Ah...

I picked up one of the harbor freight 9500 watt inverter generators and first tests indicate it's a winner. One problem I've noticed however is the neutral is bonded to the ground in the generator and I'm not having any luck finding an easy way to separate them. Has anyone seen anything on...

I installed a Growatt SPF 6kW DVM over the summer and have been 100% satisfied with it. Although a ground mount of panels is in the budget for next year, right now my only battery charging option if the grid is down long term is a Smarter tools 9500 watt (7500 running watts) generator. These...

History: I built a 16s battery for my Growatt using an Overkill 100 amp BMS and 230 amp EVE cells. It works wonderfully but I wanted more capacity so I purchased another 16 of the same EVE 230 amp cells. I also picked up another BMS, Class T fuse holder, shunt, the whole enchilada...with the...

For sale is a nearly new AIMS Power CON120AC1224DC AC Converter & Battery 12V or 24V Smart Charger 75 amps 12 volt and 37.5 amps 24 volt. I bought this new in May of this year after seeing Will used the same unit in some of his videos. It works very well but I've gone to a 48 volt system. SOLD.

For sale is a Cotek SK1500-124 Pure Sine wave 1500 watt 24 volt Inverter in pristine condition. I used this inverter as a UPS and it had no trouble with a refrigerator, large upright freezer, the television and a few LED lights. Asking $195 includes shipping conus and PayPal fee...

I top balanced and was extremely careful building the battery. These are 230 amp EVE cells in a straight 16s configuration. I'm seeing an average .005 - .007 cell delta, with #1 usually being the low cell. In normal practice, is this considered acceptable?

I'm installing a 6k Growatt, using 230 amp EVE cells. Last weekend I got all the AC wiring finished and this weekend started on the DC side. I wanted something compact and secure for the batteries, and found a metal toolbox on Amazon that fit the bill perfectly. It's tight and made for...

Going to the store later for supplies and was double checking the electrical requirements for the Growatt 6Kw unit. "AC Breaker Recommendation (double pole 240V) 8AWG, 80A (Input & Output)" This doesn't seem right to me, I'd be reluctant to use 8AWG even on a 60 amp breaker. I was planning...

1 week in and still top balancing! I have 16 of the EVE 230 cells in parallel, charging at 10.3 amps and only up to 3.357 volts.

I'm planning the install of a Growatt SPF 6000T DVM and the installation instructions indicate it's not to be mounted on a combustible surface. Does the back of these things get that hot? When my Solar Edge grid tie system was installed, they put a sheet of 3/4" plywood on the wall and mounted...

SOLD

So I'm in the process of building a 24 volt battery. My intent is to arrange 16 cells in a 2p8s arrangement, and use a 100 amp BMS. Since the Overkill BMS has been unavailable, I ordered a JBD BMS on eBay. Well I didn't read the fine print. (PRO TIP : never order eBay stuff from a cell phone...

My existing setup has the shunt to monitor charge current in the positive line. Actually I have two shunts. One in the positive charger output and another on the positive inverter input...both connected to big beautiful analog meters. Yeah, I'm old. I see most everything here specifies...

While I'm waiting on the slow boat, I have time to plan ahead on my installation. I've purchased 16 200 ah cells that will be configured in a 2P8S 24 volt block with a JBD 100 amp BMS. My application is a 1500 watt inverter that rarely goes above 60 amps surge when one of the refrigerator or...
