DMAC took advantage and collected them - Gone

DMAC took Advantage - Good luck and I hope they work for you

Ive had a desire (Not the time) to get into home automation, read my batteries and communicate with my inverter, so started researching, and thanx to this forum found some answers and how to. So I pulled out my Link sprite, bought some Tuyo switches, a bit of zig bees, mixed in my 403 Mhz and 433 Mhz's, dusted off my arduino and looked for Raspberry Pi, No one had stock, and the ones that had 2nd hand were asking prices double the value. Everything went into a bag, and thrown into my sock drawer. New hobby..... I started looking for a 3d printer, and bang found raspberry Pi 4 back in stock at the PiShop.co.za. I await my delivery and ....... more time

I Dun this

Hi also have an interest, are they available ?

Hi Stefan, At the moment I dont't know where this is going to go. The guys who supplied them seem to have a want or need if being usable. Cant make promises for now.

This Particular battery was 12 V when received, on average the cells read 3.0V. So my next thing is to charge the individual cells to see their ability. Other battery packs are between 6.0V and 10V. My Next thing is to look for a tester/meter that can give me more informative results. SOH/SOC/AH/ not just Volts and Percentage. My readings tell me of a Raspberry Pi device. Ill post in classifieds. The Battery as a complete unit is rated 55 AH . Total of 8 cells packed 4s2p. So 3.2v x 4 =12,8V and 4AH x 2 = 8AH. BODMAS not working here ? Thanx for the input I think even those Lithium packs at Builders/Leroys/China are rated 9 to 12AH, but yes packed in the std 7ah housing.

I have the VZ-3524P-FS Manual , which model are u wanting ?

Please specify the Model, I can help with VZ-3524P-FS Manual

Hi Johan I am stuck with same problem on FiveStar VZ-3524P-FS inverter : Read in posts to use 1. The software Licence No 511C1-01220-0100-478DF2A (Seems to be generic) 2. Administrator 3. Serial number of Inverter All have failed My second is I can not communicate inverter to the Fivestar 24/100 battery : And I can not find the pin outs for the inverters RS485 port. I have got the Pinouts for the battery, and the supplied straight through network cable does not work.

Waiiiit. RJ45 - Once a standard for cat 5 Network communication. Then adding Power over ethernet added, Now rs232 then RS485 then Can-Bus then remote switching, then combinations of RS232/RS485/Canbus and seeing positive +12V and or +5v . all in a 8 wire termination. And I still dont understand Earting (1 wire) on a DC system

While we do live in a city with various trees and shrubs and Roses, we gotta look back and appreciate that JHB is the biggest urban forest that we/ancestors have created for shade and wind breakers. In youre banner pic shows trees going up to roof height. but not showing the taller ones shadowing on youre panels 80 % maybe. Were we right then to plant trees, as it once was grassland. Or are we right now to utilise the sun. ? Its a big, big thing as to growing vegetables hydroponically, and growing vertically. I made a decision going solar, and I live on one of those Jacaranda streets. Having that and a Lovely Palm decided Solar. And was lucky enough to cut my Jacaranda before it become a heritage/protected tree. I dont have to clean up after it any more. My plum tree now fruits. Not sure by "might help someone" Oxygen? Plants use it ? And give it ? Walk into a room of a herbal grower. Its hard to breathe after half an hour. So is the Tigo TS04 optimiser realy necessary.?.

Questions related : The guys with the green/blue and black/white cards doing solar installs will leave the industry as the roofs are full. The Gents with the COC's being paid the 3K to sign off . The Pros will continue to fault find. Guys come down from suntanning into the automotive industry - or do the mechanics have their chance of industry Waste management are you ready ? as this gets dumped ? Where do I go from here: Ive got a welder that can do 18650 batteries, but not for busbars this thickness. So do I drill and tap Ive got a capacity checker that gives me a percentage of charge, but does not give me soc and soh or resistance, or the mAH capabilities.: Not finding it available in SA. OR are these cells just not re-usable ?

The BMS is my big dissapointment, I really was expecting to find Huge meat, watercooled system (Daly style), but I got this. (Dala style) Where do I go from here.... Are these cells a different manufacture Deep cycle to crank to golf cart Individually : Can it be recharged, checked for the bad cells and repurposed for solar use ? - or tell the company "you're problem to dispose", because repair is virtually impossible. Although the one battery supplier said he 'knows a guy' "Of Course - I replied" In this pack i found 2 cells bad - but it is packed 4s2p - so maybe 1 is faulty and destroying its partner. Looking up the battery replacement i found 1000 Euro +/- R20K replacement value. Please flush my oil.

Eventually everything pulled apart to get an inventory of Busbars - Plastic Housing - Al filler plates on side - BMS - Relay AND LifePo4 labelled 4AH 220705 63536 Google that and came up with nothing
