Doing the math, currently US$ to NZ$ = 0.60 to 1. I paid NZ$ 16k (US$ 9.6k) to get 52kWh from China to my doorstep. Admittedly, this excludes the BMS setup & Solax inverter. The latter added about NZ$ 4k (US$ 2.4k) to the total, still a huge saving.

I use some 200Ah LiFePO4 cells with 5 strings of 16 in parallel, imported from China Factory, see details in spec sheet. I am very happy with the performance, doing exactly as specked. The caps i use are ordinary electrolytic caps, just fairly large ones (total of 1.32 Farad). I implemented the...

I would have needed 4 x 12.5kWh power walls to equal this setup. I imported 80 x 200Ah LiFePO4 cells (5 strings of 16) directly from China Factory, was a HUGE saving. I am also very happy with performance, did one DOD to almost 98% and delivered the rated energy with no problem at all.

Hi Doug. The default for the cutoff time is 10 sec. For my scenario I set it for safety to 0 seconds, I have a 1000Ah 52V lithium iron battery on my solar system for my house and can turn catastrophic if things go wrong. I do have circuit breaker protection also, but rather play it safe...

With a little more tweaking on excel, it now also show the Max & Min voltage cells on every update just as the display unit does.

Hi all. After much struggling I managed to get the BMS16T onto plain old simple excel. See pictures below:

Hi Craig. On the Chargery website, they have a small test program "USR-TCP232-Test V1.4.exe", when the unit is set up as "TCP Client", the test program shows the data coming from the BMS as "Network Data Received" as per the attached page. At Least this confirms the data to be converted from...

Apologies for that.

Apologies for that.

Hi All. I missed to share one drawing with you guys, the "Modified BMS Connections" drawing, showing the small 12VDC interposing relay circuit. Here it is:

Thanks for the larger screenshot, looks perfect! When I studied the USR units, I noticed that they have a "Httpd Client" mode and I imagined that I somehow could use the "Httpd Client" with the "GET" command directly via a web browser, but as yet don't know how to do that. Any thoughts on this...

Hi Graig. Thanks for your reply and the screenshot. Also thanks for the suggestion of the N540, I do have other stuff that I can connect to the other ports also. As far as I can gather, the USR unit need to have websocket capability, else it won't work. I also posted some higher quality images...

Hi Craig. I had my BMS up and running since February (2 months now) and pretty mush ironed out the settings for it. Being an electrician, the hardware side was no issue for me but I am a bit of a novice on the software side. Not knowing where to start, I got myself a USR-TCP232-302 but am not...

Hi Craig. Can you please do a screenshot of your data you get on your PC from the setup you have done.

If you guys are interested, here are some higher quality pictures below of my system and some screenshots of the settings of the Chargery BMS in pdf format.
