Thanks for answer. The wheel are 1.5m in diameter, so its got alot of power with all that water pulling. And i was thinking about this gear unit from Aliexpress, the waterwheel dont go fast, but its powerful, so the gear ratio fits fine.

Hello all you creative inventors out there.. I have this remote cabin with 800w solar and a 24v/230v/3000w inverter. kind of a modern setup in a small cabin far into the woods.. in february to september its no problem, plenty of Solar/battery power. But in the darkest wintermonths there is...

Yes, the best would be to have a standalone panel just for the heater. Then it wont mess with the batteries.. maybe the panel will be covered in snow, maybe not. With luck, the temperature in the battery is on the +side when i get there in the winter. Is'nt it like using a 100w heater on a...

Hi. I have a cabin with a 24v 12kw li-ion battery setup. 230v/3000w inverter. Its installed a heating cable in the insulated batterybox that is controlled by a 230v temp thermostat. In wintertime, when i arrive at the cabin , i turn on the inverter, the heating cables heats the batteries to...

Thanks for answers, I'l do some testing and report back my findings.. I will also check the balance setting. The batteries are of the same type cells, all cells are tested with a capacity tester. After a storrage period on my cabin, with main switch off, its allways battery 2 that is slighty...

Hello. I have two jk B2A8S bms mounted on two 250a 24v li ion batteries. All working fine. No alarms. I find that one of the batteries selfdischarges faster over time(several weeks) than the other one. The battery Main switch is turned off at this time. Can one of the bms be foulty? I would...

I ask this question becouse i'm looking for any ways to try to save some power. Here in norway its getting dark now in november, and at my off grid cabin its wery low chargig ang to high resting power consuption from the inverter/charger (epever up 3000hm10022) its about 30watt/h just having...

Anyone tryed this "Smart Sleep On" setting? What do this setting do? Is this the same as turning off the bms with long-press on the button?

Now this came out on youtube... Something new going on?

There is a new wifi module in the marked now. I asked the support about it, it is in stock, but it's taken back for an upgrade.. so soon the new version are ready.. its wifi, - redy for cloud. The name i wifi module rf45 D https://www.epever.com/product/epever-wifi-adapter-2-4g-rj45-d/

Agree to that the heating should heat before the temp cutoff turns on. Only thing could be that id the battery is stored in the dark wintermonths with litle solarpower, it will drain the battery(maybe.. ) , so in my case,- i have the battery in a remote cabin, with not so much solar power in...

Hi. I'm planning swapping my qucc smart bms to a jk smart heat bms. About the heat output; do the bms start heating ALWAYS if the temp sensor open for heating? Or do the bms ONLY start heating when charging and the temp sensor open for heating? Or is all this adjustable in the settings?

Thanks. Interresting... seems the victron is the one that uses the least amount of power.. I think average wifi router is about 5watts.. but have not tested myself. Guess i need to order a victron then.. ?

Hi. Anyone tested power draw from a victron gx lte 4g transmitter/receiver vs using a 4g wifi router to connect from a cellphone ore remote pc? I need a new router, but do the victron gx lte use less power? Tryin to make it use as little power as possible in the darkest winter days when...

I stil have'nt found a way to display the battery temp sensor on the main page in the App. It can be seen in the setting, but not on the main. Its the same issue on the external lcd monitor for the bms. I kinda just have to trust the bms doing its job..

I found a solution i think.. i sat the bms (no power connected)on my workbench for a couple days, its a small room with constant 20C in the air.. i put a digital temp monitor beside it. After a couple days the whole bms was 20 degrees C. Then i adjusted all the sensors to 20.. it seems like...

Cool, maybe thats the way to go..

Works fine in Norway..

Do you manage to get some spec or any cell info for the cells? I know it's a nms cell, but can just find some standard nmc cell info online..

Yes. A predator 3500i .

SOLVED. the firmware upgrade in the inverter/charger dud not fix it . Replaced the invertermodule in the generator, that fixed it. Working fine now.

My 4g module is also offline. It's a cloud problem.. lets hope it don't take long. ..

Epever support sendt me a new firmware.. i will install and test again soon...

Thanks, i think you are on to something here.. ? i have sendt all my mesurements and all info to rhe epever support. Recomending to test it themselves, and update the firmware if possible. Is there anthing i can do to trick the inverter or the generator to think it's all right?

I have a nmc lithium 24v ev battery pack. The bulk charge is set to 28.7v(4.015v/cell) and float is set to 28.5. Bulk reconnect is set to 28v.

I don't think it's any wrong with the settings , i agree that the amp is realy low in float, so it cant be the amp draw thad overload the generator. I think its something with the inverter/charger in the moment it goes from bulk to float. Some strange voltage peak, power peak or something that...

Tested some more .. connected a 2800watt heater direct to the generator. It run the heater with no problem?. So.. the generator is ok. Then i connected the heater to the inverter and decharged the battery to about 50%. Then connected the generator and tryed again.. now the gen started charging...

If you press and hold the "ac" button. The right one, you turn off the inverter, not mppt.

Thanks for tip, I'l look into that.

Hi. I have this all-in-one inverter/charger in my solar system. Works great. Ifs a Epever 3000-hm10022. 3000watt/230v max 100A charge 24v battery. But now, when i connect the generator, a loncin(predator) 3500i , to the grid (generator) input , the generator goes into overload mode. I'v...

I also have the same issue.. it seems that when the battery hits float, the generator goes in "overload" . wierd.. Did you find a solution for youe problem?

Tryed this? Not the same controller, but still cloud setup.

Support@epsolarpv.com

I also got info from the support that nextyear they will make a upgrade in the inverter that make automatic firmware upgrade..

Ok, so the wifi is not any better.. we keep on trying.. i have also contacted epever Patric on messenger/facebook/youtube. He has not ansvered yet. He make instruction videos, and also work at epever solar.. maybe if you to try to contact him, you can get a ansver?
