I've done a quick search on cooling and many solutions posted here seem heavily engineered and expensive. My offgrid solar system saves me about $2 a day from my electricity bills, so I have opted for using a cheap domestic evaporative cooler: That works quite well on its own, but I can...

First of all, hello to the forum and thank you for having me on board. I don’t think I’m a typical member. I am not a DIYer. I did physics at school so I understand Ohm’s law, but I am not practical. I am here to overcome the ridiculous constraints of Australian regulations and the profiteering...

This is a continuation of the thread I started in the introductions forum, and here I shall describe how the project progresses (or doesn't). The first step is to get the shed roof ready for the solar panals, and to that end I have taken delivery of a box of aluminium ties. Left over from...

Just picked up six used Suntech stp175 panels to add to my off-grid array. The specs for this panel show a male connector coming off the positive side. But when I got home I noticed a strange female female dongle had been connected to the positive terminal to make it female. And the negative...

Does anyone else lie awake at night worrying about whether their BMS is going to fail? And if so, do you always keep a spare on hand – just in case!

I ordered this product in April at the same time as my first batch of LiFePO4 cells, but the cells took a lot longer to ship and I had nothing to test it on until the cells arrived just now. I've probably used up all of the AliEexpress complaints period, so note to self: synchronise product...

One cell out of eight in a 24v 8s LFP battery is jumping from 3.336V when idle to 3.791V as soon as the battery begins to charge. Any ideas as to why this might be? Is the BMS possibly giving false readings or does this cell have a serious problem? I made a screen recording of what happens when...

I have been using the jk-b2a8s20p with an 8S LFP battery for a few weeks now and everything seems to be working except the temperature sensors. Both T1 and T2 show the temperature as NA. I thought at first I had a setting wrong, and then I did some reading and learnt those readings come up...

I roll my eyes a bit when people warn of the dangers of charging LiFePO4 cells below 1º c because I live in Australia and I am more worried about keeping the cells cool when the ambient temperature goes over 40º. So I set up a bench test with the charging cycle to run over night, and before...

While working on my solar project I’ve joked with my boys that I’m preparing for the apocalypse. Three days into a 4 day power outage, they’ve joked with me that I am poorly prepared! My off-grid circuit with a 2S4P 195W solar array and 8S 24V 304Ah battery is fine for getting me through the...
