The pop up hints do not change when you have parallel inverters so in effect they LIED to you.
My discharge max says it cant go over 110, but I have it at 125? Hmmm LIES!!!
With your usage patter,If these batteries were not turned off routinely, that would explain everything. The Battery management system consumes power and I doubt its included in the SOC value displayed.
Inverter based dryer? If not, some "low power" drying modes do use less amps. Mine is not like that....
Hut tub?? haha I wouldnt feel lucky if I were you. Heat is heat no matter how you slice it. What breaker is it on? That will be your best clue!
Put a smaller heater in there?
I just put...
I support all the conclusions presented.
One BMS for each group is absolutely ideal, but I wouldnt consider it mandatory. It would be tremendous insight into how the orphan pack is doing, spot trouble much easier (abnormal cell deviation would be masked if 2 in parallel) , and allow twice the...
Having one BMS that is at least close to the parallel bank would be miles better than what I am doing. All I want to do is leave enough space in the battery for the next days sun. I hate losing watts because of full batteries.
I will definitely be looking into that project.
I am sorry and sad that this happened to you. What is that low cell about? It isnt circled in the photo. 3.26- 3.0 is quite the spread! That could possibly be one at 10% and one at 60%.
I would say that is too close. It is certainly not worth it given you probably wont lose anything besides another run of 10 awg
Smart plan.
Because you will hit it on a cold mid morning and every single time your batteries are full with the sun out. Over voltage is the WORST thing you can do...
Using a Kilowatt meter like seneysolar mentioned for the inverter output would be a great step.
You also could use a meter on your battery before the inverter. A Victron Smartshunt would be ideal and a wonderful long term investment for measuring exactly what is going into the battery and out...
This is true but a lot of the new routers only have one SSID and decide what feed to give a device. My guess is the OP is using a 2.4/5ghz bridged SSID and the dongle cant grab the 2.4 because it cant see it.
The manual references "Working Modes" But I have not found any documentation on how to change or test these settings. Searching the pdf manual for "Bypass mode" I get nothing that will help me change to it...
It appears I am stuck in off grid mode and this is not ideal. I am not looking to...
I guess I should say that Im pulling in 3300 watts into each PV input with peaks nearing 4000. So Im using it pretty close to its fullest.
I know when clouds are rolling thru from the sound in my kitchen and the 6000xp is in my basement.
:)
Yup, this is what happens to me with my 6000xp and is my biggest complaint... I didnt know what was causing that.
So far this happens with the JK inverter BMS and the victron shunt mod that converts it into a fake BMS
Are panels wired in parallel? What is your PV line voltage?
If you have them wired in parallel they might not have enough voltage to charge a 24v battery.
What is your battery voltage? Are they in parallel?
Bulk means its trying to charge.
I recommend getting the Victron bluetooth adapter so...
Looks good to me! But of course wait for a couple more people to chime in.
Nice detailed diagram!
It would help if you gave a link to your buss bars.
Their is no spec listed and they are pretty important
I am not sure. I Calibrated to hit 99% at 3.65/cell and now am charging to 3.48. Not an issue really. I know turning off the pylon switch helped but I remember it triggering again. Let me know what you figure out.
I love when we talk about compression/ no compression. That convo has never been settled, yet here we are talking about compression that isnt demonstratively perfectly equal.
Compression can kiss mine.... If I need to replace my batteries in 7 years vs 12 Im ok with that. Sure beats bashing...
Im in Wisconsin in an unusually "not as cold" winter. My panels have been at about 85 percent since the 3rd week of feb. My angle is at 42 degrees My 3600 watt array is getting 15-21 kw on a typical good day. I think my angle is actually perfect for where the sun is right now and less ideal in...
Yup, Fuses by nature get warm.
I think mine at a 80 amp draw gets to about 130F Mine is an ANL fuse. They are notoriously warm.
If you are SURE that the fuse lug connections are good, and there are NO washers between the lug and the fuse, You are fine.
No drilling lugs either, NO bright...
I am surprised to hear of an EVE 304 having a problem at the 2 year mark.
What typical and max currents were you pulling?
I understand this problem. I have seen this behavior for the last decade. It is not unique to LiFePo4, it is every chemistry including lead acid , tho you just dont notice...
