Thought id give something back to the community. Not sure if its been done before, I didn't see it here, but I have managed to decode the data from a wide variety of PV inverters, Grid tie, storage etc, written a python script that outputs to influxdb then you can read off in to grafana or...

Just thought I would update everyone, after lots of back and forth and finally getting through to a very helpful support guy at Seplos we run tthough all the tests he asked, he confirmed it was faulty and passed the email chain back to Adam in sales who straight away sent me a new one, they sent...

Thought some of you might like a look at the bench supply I purchased to balance my Lifepo4, nice colour display and only $60 / £55 Its app and PC controllable which means you can monitor remotely, has built in wifi and has battery temperature probes and provides graphing and data logging...

Today my delivery of 32x 280ah LFP cells arrived from Senbry, these were listed as brand new EVE cells, he was a seller on here but has since been banned for advertising at every opportunity as fas as i know. I paid $70 per cell plus $4 per Kilo shipping by train. total was just under $3100...

Hi all, yes happily upload the pi images for you, I use a cheap RS485 to USB adapter $3 from amazon. I have now have written node red flows for Sofar, Ginlong/solis both 4th gen and the new 5th gen units, growatt and solax inverters, more flexbile than the early python scripts. I believe many...

I have held off naming and shaming as I have been an advocate of this suppliers products for some time and actively supported their UK buyers despite not being affiliated with them at all. As some of you may know, I purchased four of their 280ah cells cases including BMS which they shipped but...

So quick update I did a capacity test from 100% down to 0% yesterday with a draw of 20amps, and the pack reported 286ah to empty which im super pleased with. so far these are looking like a bargain. well chuffed.

This has got danger written all over it, LiPo cells + no BMS

Why would you spend decent money on an LFP pack and cheap out on the SCC? surely you want to protect your investment of the Batteries?

Note to self, turn speakers down before watching any videos. That genuinely scared the sh1t out of me

You can manually change the SOC, normally when I set these up for a customer, I top balance all the cells to3.65, hook up a new Seplos unit, login with admin & admin, go to upload settings, change the battery capacity,rated capacity, then change the SOC ah to whatever the cells are rated for...

I would never have thought to remove the last two pins, I just put a new crimp on with 5&6 and its working exactly as described. hundred percent sure only 5&6 are needed, thought maybe Seplos would have come across this before and made that their first mention in the support email but that was...

Now top balancing them as per @Will Prowse video using my super duper new power supply.

The cost per cylic discharge and the toll on the battery packs isn't worth it in the long run, I did this very thing when I had my grandfather Go tariff at 5p import with agile export which they no longer allow you to have both. The SOH of the battery being constantly hammered at full rate to...

I import a lot of stuff from China on a large scale, hundreds of thousands of $$ of LED display units for my business. we usually opt for "FOB" freight on board and arrange our own handler to receive the goods and clear customs and forward on to me. The key to import is the HS code used and...

Why bother with the Google Pixel device, tethering and a separate AP, you can get all in one LTE routers with an external SMA connector, cabled directly to a directional Yagi antenna directly to your house in a P2P config, a cheap 12V buck /boost converter to run the router directly, then hook...

You cannot connect any equipment that has the ability to feed back to the grid, be it software limited G100 or not in the UK without post install notification (under 3.68kW) G98 or prior approval G99 (greater than 3.68kW). The G99 procedure is there for several reasons, 1) for any equipment that...

I mean this in the nicest possible way, several people have already given you a simple and correct answer to your question. Rather than potentially destroy a decent working panel, get a simple MPPT controller that outputs for your 12v configuration, I have just had a look on amazon.ca and there...

Thanks to the help from @tictag @MisterSandals and many other members with my initial DIY 1.5kW install I have decided to go full roof PV. I have sold on my initial equipment and hybrid inverter and invested in 22kW of roof mounted LG all black panels, solar optimisers and 10kw solis grid tie...

To be fair, the shipping cost was from the UK to Austria (not back to China) and the price not set by Seplos, that was my cheapest quote I found myself to return it insured.

Point F would be the most logical place, as its the combined end point for both negative leads from both battery packs.

Another update. Things seem to be just as id wanted. The pack now discharges down to 20% and recharges to 80% during the day, all cell voltages are good and very close. Ive completed four cycles so far without issue. As a side note my other 16s cell pack with the bloated battery also now seems...

The main thing is it works and really well.

To chime in, I made a really small but smart "UPS" with a boost converter / charger from a single 3.2V LFP, runs my raspberry pi just lovely

The manual even shows the correct way to cable them for single parallel config

More tin foil needed for you. firstly microtik are owned by a Latvian company with 60% Russian ownership. That’s your first mistake as that was on your initial not to trust list but you have it as the core of your network and they use Chinese made hardware based on open router board, which...

It doesn't unfortunately, but I have just bought an inline one with remote monitoring back to my PC so will see how that goes. Svetz, this is just a small beer style fridge, no freezer or anything, this is the charge rate im seeing at the moment, batteries seem to be at 80% in the morning after...

Hi Mr Funk I have a new pi image specifically for the Solis inverters, its ready to go, you will need to remove some dashboard items as I have three solis inverters so you wont see any data for two of them with my image. I will upload to the resource section for you. I dont have a guide...
