I supported the Caia heliostat project on Indiegogo. Last spring, after waiting 6.5 years (!), I finally received my 4 units. Three of them are still working fine after a year out in all weathers, but the fourth never worked properly from Day One. I'd love to get it up and running. I did try...

The original glass panel broke, so I removed the remains. I have been unable to source a replacement with the original specs, which are: Textured glass, 3.2mm, tempered, low iron content, 1.742m x 1.135m The nearest I came was a supplier in China, but minimum order is 25 pieces. The...

Ah ok, thanks. I have setting 16 Charging Source set to Only Solar. I'll change that to Solar First (switches to utility charging if solar not available) and see. I'll leave current settings for 12 and 13 at 24V and 25.5V and see how she goes. I always thought of charging the battery from...

It's the unknown unknowns that get you: I got rid of the old, tired lead-acid cells and installed new LifePO4s, with Daly BMS. All seemed fine. But... If the battery pack gets low (24V in my case) due to a prolonged lack of sunshine, the hybrid controller switches to utility power. A while...

Hi, sorry for the delay in replying, I became sidetracked with other things. And no problem mjrogers for the hijacking :0) Here's what the BMS manufacturer Daly said: "Hello Sir, The Balancing start when trigger the equilibrium condition. Pls check the datasheet of the active balancer."...

Good suggestion thanks, but that's not a toggle, it's just a display, the toggle is on the Active Balance screen, but it's greyed-out, presumably because two parameter values are showing zero and it won't accept new values. But the good news is all cell voltages are within .01V now, one was...

I feel such a complete idiot - that loose nut was the problem. Thank you so much. Can't believe I didn't notice or check that! All others checked now of course. And yes, I'll add ring terminals later. However, the Balance Current and Battery Strings settings in the app are still at 0 and won't...

Good idea, I dis- and re-connected the BMS - no change. I un- and re-installed the app - no change. Interestingly, the same bad readings were showing in the app even with the BMS disconnected from the battery (but with the sampling wires still connected). I'm thinking the BMS has failed, but...

I tried that too, but no response.

My BMS is giving me strange readouts. After assembling my 8 x 3.2V LifePO4 24V battery pack, I connected the Daly 8S 24V 60A BMS then connected the solar charger, correctly set to LifePO4 battery type. I checked the BMS app and it correctly showed temperature and the individual cell voltages...

After an accidental short circuit (that did not blow a 13 amp fuse in the appliance's plug, nor did it trip the circuit breaker at the main board in my home), my inverter stopped working. The unit shows error code 6, the suggested solution being "return unit for service". The unit works fine...

Oh well, was worth a try. My own research took me to a web page called BMS Picker. I've ordered a Daly 8S 24V 60A with Bluetooth through Amazon.

Thanks for the reply. I had a 3-way (grid/gas/12V) absorption fridge in my caravan (trailer in US-speak), it was horribly inefficient - 120 watts constantly, but interesting to know better 12V options are available nowadays. My much larger domestic fridge/freezer needs about 40 watts when it's...

Thanks for the reply. Night time load is about 50 - 200 watts while I'm up. Day time varies greatly from near zero to a max of about 1200 watts if the washing machine ever needs to heat water in very cloudy winter weather (about twice a year), in which case the system trips almost instantly to...

Hi all, I'm new here. I'm replacing my 8-year old 12 x 2V 250Ah lead acid batteries (that are down to about 0.5 kWh capacity) with 8 x 3.2V 140Ah LifePO4. I'm aware that I need a BMS, so before I start Googling and getting overloaded with info, I wondered if some of you might have some pointers...
