The Growatt Shine Phone app has been driving me crazy and I decided to dump it in favour of SA. Had a Rasp Pi Zero W laying around and decided to accept the 30 day free trial of the software. Flashed a 16GB SD card and had the whole setup running in under 30 min. What a pleasure ! Will never go...

I have been running the inverter on a 48v 16s self built battery for about a year without any problems and only monitoring and making setting changes via the JBD BMS on the BT app - no comms between battery / inverter. Charging voltage set to 54,6v ( setting # 19 ) due to errand running cell...

Has anyone successfully revived a faulty LiFe cell / cells that have dropped below 1v ? 2 of a batch of 28 cells arrived from CH in that state. Currently charging / discharging them to see if they will recover. Any advice or comments are welcome.

I need a good quality boost converter as follows : DC input voltage : 48 - 60v DC output voltage : 150 - 180v Output current : 10 amps. I am experimenting with converting PV energy into heat energy in the water heater. Instead of powering the heating element directly from the PV panels I would...

Shown here is a 48v 100aH battery built into an ammo box ( ZA version ) The build consists of 16 x A grade LiFePO4 battery cells controlled by a 200A JBD BMS. Only problem at the moment is that I do not have a 48v mains charger , so I charged the battery in 4 x 12v groups with a Victron Blue...

I have just received a new batch of A grade cells that I will be testing with my favorite DGJBD Bluetooth BMS. The cells are 100Ah LiFePO4 measuring 230mm (top of stud) x 135mm X 35mm and nice beefy 8mm terminals. In future I will only use stud type batteries as the puny 6mm screw type terminals...

a While ago I bought this tiny Split Port 4S BMS on Amazon for about $10 . Rated at 100 amp , so I was not convinced. It arrived in a little brown box without any label , spec sheet or user manual. Obviously some kind of bypass relay had to be used to handle the current , so I hooked it up to a...

Oh how I wish for the US to metricate a little faster ! It will be such a blessing if the whole world can be communicating in ‘metric’ . Come on US , you must be one of the last nations on earth to still cling to the old imperial system. I suppose I am going to be lambasted for this.

Has anyone used the 3pin port on the side of this meter ? I have noticed that Will P has a few of them in service. The pins are marked "+" , "-" and "U" and I thought that it is some kind of a comm port for external measurement or data logging...

Until recently I have been using Daly Common Port BMS's in my experimental 12v LiFE 100Ah 4S battery pack. Very pleasing results getting in excess of 1500Wh on the discharge cycles. 'Curiosity killed the Cat' and after reading / watching Will experimenting with Bluetooth BMS's I decided that I...

I am experimenting with LiFePO4 100ah battery packs and recently received my new Tenergy T180 balance charger for cell management. The capacity can however only be set up to 50 ah and meter gave me an error message when wanting to balance 4 x 3.2v 100 ah cells in series. Looks like I made the...
